The global demand for timber is increasing, with prognoses for the EU showing particularly high growth to meet renewable energy targets. However, there are limited options to meet rising timber demands within the EU, and global land competition to meet world food, energy and material needs, as well as to conserve high value nature areas, is increasing. This dissertation addresses the knowledge gap between the pressures of increased land use abroad and the underlying drivers of land use change. It argues that there is a high risk of problem shifting if EU policies to increase timber consumption are not accompanied by a monitoring system that accounts for consumption levels and provides a benchmark for sustainability.
The German government has set itself the target of reducing the country's GHG emissions by between 80 and 95% by 2050 compared to 1990 levels. Alongside energy efficiency, renewable energy sources are set to play the main role in this transition. However, the large-scale deployment of renewable energies is expected to cause increased demand for critical mineral resources. The aim of this article is therefore to determine whether the transformation of the German energy system by 2050 ("Energiewende") may possibly be restricted by a lack of critical minerals, focusing primarily on the power sector (generating, transporting and storing electricity from renewable sources). For the relevant technologies, we create roadmaps describing a number of conceivable quantitative market developments in Germany. Estimating the current and future specific material demand of the options selected and projecting them along a range of long-term energy scenarios allows us to assess potential medium- or long-term mineral resource restrictions. The main conclusion we draw is that the shift towards an energy system based on renewable sources that is currently being pursued is principally compatible with the geological availability and supply of mineral resources. In fact, we identified certain sub-technologies as being critical with regard to potential supply risks, owing to dependencies on a small number of supplier countries and competing uses. These sub-technologies are certain wind power plants requiring neodymium and dysprosium, thin-film CIGS photovoltaic cells using indium and selenium, and large-scale redox flow batteries using vanadium. However, non-critical alternatives to these technologies do indeed exist. The likelihood of supplies being restricted can be decreased further by cooperating even more closely with companies in the supplier countries and their governments, and by establishing greater resource efficiency and recyclability as key elements of technology development.
Der Verfasser legt eine vergleichende Analyse von Abfallwirtschaftsregimen in drei deutschen Stadtregionen vor. Als Fallbeispiele wurden Frankfurt in der Rhein-Main-Region, Berlin als Kern der Metropolregion Berlin-Brandenburg und Bochum im Ruhrgebiet ausgewählt. Einerseits weisen die drei Stadtregionen eine ganze Reihe von Gemeinsamkeiten auf, die sie für einen solchen Vergleich geeignet erscheinen lassen.
Alle drei Stadtregionen bilden Zentren wichtiger Metropolregionen in Deutschland, denen angesichts ihrer Bevölkerungsdichte sowie der ökonomischen und politischen Bedeutung besondere Relevanz für die Planung von Infrastruktursystemen zukommt. Gleichzeitig unterscheidet sich jedoch die Bedeutung der drei Fallregionen innerhalb ihrer Metropolregion durchaus deutlich, von der absoluten Dominanz in Berlin-Brandenburg bis zur Polyzentralität im Ruhrgebiet, woraus sich auch unterschiedliche Herausforderungen an regionale Planungsverbände und die Gestaltung der Kooperationsbeziehungen mit den Umlandgemeinden ergeben.
Als Bestandteile von Metropolregionen sind sie alle drei intensiv in internationale Geschäfts- und Wissensnetzwerke eingebunden, sind Standort für die Entwicklung soziotechnischer Innovationen und verfügen in vielen Bereichen über hochqualifizierte Humanressourcen. Auch im Hinblick auf die spezielle Situation der Abfallwirtschaft zeigen sich vergleichbare Ausgangsbedingungen: In allen drei Regionen wurde auf eine vollständige Privatisierung der kommunalen Abfallwirtschaft verzichtet, nach wie vor werden mit der Sammlung und Entsorgung von Abfällen Unternehmen beauftragt, die sich überwiegend im kommunalen Besitz befinden.
Poor sustainability and increasing economic shortcomings in fossil raw material use besides further technical developments of substitutes lead to a growing potential for CO2-utilisation. Hence, we balanced CO2-based methane and methanol production in a life cycle assessment and identified CO2-utilisation as a greenhouse gas saving method. However, it requires a lot of renewable energy.
Biodiversity loss is widely recognized as a serious global environmental change process. While large-scale metal mining activities do not belong to the top drivers of such change, these operations exert or may intensify pressures on biodiversity by adversely changing habitats, directly and indirectly, at local and regional scales. So far, analyses of global spatial dynamics of mining and its burden on biodiversity focused on the overlap between mines and protected areas or areas of high value for conservation. However, it is less clear how operating metal mines are globally exerting pressure on zones of different biodiversity richness; a similar gap exists for unmined but known mineral deposits. By using vascular plants' diversity as a proxy to quantify overall biodiversity, this study provides a first examination of the global spatial distribution of mines and deposits for five key metals across different biodiversity zones. The results indicate that mines and deposits are not randomly distributed, but concentrated within intermediate and high diversity zones, especially bauxite and silver. In contrast, iron, gold, and copper mines and deposits are closer to a more proportional distribution while showing a high concentration in the intermediate biodiversity zone. Considering the five metals together, 63% and 61% of available mines and deposits, respectively, are located in intermediate diversity zones, comprising 52% of the global land terrestrial surface. 23% of mines and 20% of ore deposits are located in areas of high plant diversity, covering 17% of the land. 13% of mines and 19% of deposits are in areas of low plant diversity, comprising 31% of the land surface. Thus, there seems to be potential for opening new mines in areas of low biodiversity in the future.
Das Projekt "Ressourcenpolitik" (PolRess) begleitete die Debatte um die anspruchsvolle Ressourcenpolitik, zu der sich Deutschland verpflichtet hat, aus politikwissenschaftlicher, juristischer und ökonomischer Perspektive und setzte dabei auch selbst Impulse.
Der Abschlussbericht fasst Überlegungen des Projektteams für die Weiterentwicklung der Ressourcenpolitik zusammen. Darin heißt es unter anderem, dass das in der Nachhaltigkeitsstrategie erfasste Ziel der Bundesregierung, die Rohstoffproduktivität bis zum Jahr 2020 gegenüber 1994 zu verdoppeln, wohl nicht ohne drastische Maßnahmen (wie einem Ausstieg aus der Braunkohle) erreicht werden kann. Da das hiesige und derzeitige Niveau der Materialnutzung weder global verallgemeinerbar noch langfristig tragfähig ist, müsste die abiotische Materialnutzung Deutschlands (einschließlich der ungenutzten Entnahmen) um bis zu 80 Prozent bis 2050 reduziert werden.
National policies for resource efficiency and waste management : structures, impacts, and deficits
(2015)
The current utilisation of natural resources in Germany and Europe is not sustainable, as inter alia stated by the German government as well as by the European Commission. At the same time, increased resource efficiency could lead to various environmental but also economic benefits. This brief study commissioned by Changing Markets presents developments in the field of resource efficiency policies, analyses the status quo of resource consumption with a special focus on fast moving consumer goods and describes potential effects of resource conservations.
Rohstoffkreisläufe sind eine aussichtsreiche Möglichkeit, die Abhängigkeiten von natürlichen Ressourcen, die knapper werden, zu reduzieren, Kosten zu sparen und gleichzeitig die Umwelt zu schonen. Die Schließung von Stoffkreisläufen steht hoch wie nie auf der politischen Agenda: Angesichts schwankender und absehbar steigender Rohstoffkosten und vermehrter Unsicherheiten über die Versorgung der Industrie mit Rohstoffen wird die umfassende Transformation der Abfallwirtschaft zu einer Kreislaufwirtschaft zunehmend als Schlüssel für zukunftsfähiges und erfolgreiches Wirtschaften gesehen.
Der vorliegende Bericht bietet einen Überblick über innovative Technologien und Verfahren, Primär- durch Sekundärrohstoffe zu ersetzen, basierend auf einem Screening aktueller Forschungsprojekte und Fachpublikationen.
Einsparpotenziale beim Kunststoffeinsatz durch Industrie, Handel und Haushalte in Deutschland
(2016)
In the future, the capacities of renewable SNG (synthetic natural gas) will expand significantly. Pilot plants are underway to use surplus renewable power, mainly from wind, for electrolysis and the production of hydrogen, which is methanated and fed into the existing gas pipeline grid. Pilot projects aim at the energetic use of SNG for households and transport in particular for gas fueled cars. Another option could be the use of SNG as feedstock in chemical industry.
The early stage of development raises the question of whether SNG should be better used for mobility or the production of chemicals. This study compares the global warming potential (GWP) of the production of fossil natural gas (NG) and carbon-dioxide (CO2)-based SNG and its use for car transport versus chemical use in the form of synthesis gas. Since the potential of wind energy for SNG production is mainly located in northern Germany, the consequences by a growing distance between production in the North and transport to the South of Germany are also examined.
The results indicate that CO2-based SNG produced with wind power would lead to lower GWP when substituting NG for both uses in either transport or chemical production. Differences of the savings potential occur in short-distance pipeline transport. The critical factor is the energy required for compression along the process chain.
Reforming the EU VAT system to support the transition to a low-carbon and resource efficient economy
(2015)
This chapter discusses the question of ecologically differentiated value added taxes (VAT) as a tool to overcome tax-related cognitive barriers by connecting to an existing tax system. This is elaborated along several aspects: (a) The role indirect of consumption taxes for the economy, (b) the legal issues of the VAT system, (c) the EU harmonization efforts in this context, (d) the distributional implications of value added taxes. Following this, the chapter develops a proposal for a VAT reform (e). To this end, it looks at potential and existing differentiations between sectors, products and services, and product and service groups and turns to those consumption areas that are widely identified as particularly resource and carbon intensive and sets out how a harmonization of the overall system and an ecological differentiation in single consumption areas could be brought together. Potential impacts and effects are briefly discussed (f) and some conclusions are drawn (g). The subject addressed in the chapter is relevant from a policy perspective but mainly descriptive: It does not use innovative qualitative and quantitative tools.
The rising global demand for metals in a context of declining ore grades is driving the opening of new mines and the expansion of existing ones, disturbing substantial land areas (especially by open pits). However, how much land is currently disturbed globally? How much land could be disturbed by metal mining in 2050? This study investigates the global area disturbed by mining of iron, bauxite, copper, gold, and silver for the first time. The first part consists of the calculation of the specific land requirements, i.e. the area newly disturbed caused by the ore extraction at the mine site. The second part addresses the global area disturbed in the year 2011 whereas the third presents scenarios of how such area might evolve until 2050. The last part addresses the current and future pressures on global biodiversity by metal mines and shows possibilities for the future opening of new mines in low biodiversity areas, alleviating pressures in high biodiversity ones. This study presents the findings of the author´s dissertation hoping they are used as a frame to develop policies and incentives to reduce the amount of area directly disturbed by mines and their pressures on biodiversity.
Im Rahmen des Forschungsprojektes wurde auf der Ebene von privaten Haushalten untersucht, in welchem Ausmaß eine Bedürfnisbefriedigung mit materiellen Gütern innerhalb der Randbedingungen von globaler Gerechtigkeit, einer nachhaltigen Rohstoffnutzung und einer umweltverträglichen Gesellschaft möglich ist. Zur Bestimmung des Rohstoffbedarfs langlebiger Haushaltsgüter wurden das methodische Konzept der Verfügungskorridore entwickelt und empirisch fundiert sowie global tragfähige Ausstattungen für verschiedene Haushalte prototypisch dargestellt. Das im Rahmen des Projekts entwickelte Webtool veranschaulicht wesentliche Ergebnisse des Forschungsvorhabens. Vor dem Hintergrund ihrer eigenen Haushaltsausstattungen wird den Nutzer/-innen des Webtools das Forschungsthema "Rohstoffverbrauch und Nachhaltigkeit" exemplarisch veranschaulicht, wodurch eine konkrete Reflexion des eigenen Konsumverhaltens ermöglicht wird.
Kartierung des anthropogenen Lagers in Deutschland zur Optimierung der Sekundärrohstoffwirtschaft
(2015)
Deutschland hat ein enormes Vermögen in Form von Bauwerken, Infrastrukturen und sonstigen langlebigen Gütern angehäuft. Hierin befindet sich ein wertvolles Sekundärrohstoffreservoir - ein anthropogenes Materiallager. Es ist als Kapitalstock der Zukunft zu begreifen, den es systematisch zu bewirtschaften gilt. In der überwiegend Input-dominierten Ressourceneffizienzdiskussion findet dieser Kapitalstock bislang nur wenig Beachtung. Eine Ursache hierfür ist unzureichendes Wissen über die Größe und Zusammensetzung dieses Materiallagers sowie über dessen Veränderungsdynamik. Das Vorhaben sollte dazu beitragen, die Wissensbasis diesbezüglich deutlich zu erweitern. Mit den Ergebnissen des Projektes liegt nun ein differenziertes Bild über Materialflüsse und Materialbestände vor, die in langlebigen Gütern in Deutschland gebunden sind und von diesen ausgelöst werden. Neben umfangreichen Daten wurde ein Konzept vorgelegt, das Grundlagen zum Aufbau eines langfristigen Monitorings des anthropogenen Lagers durch eine kontinuierliche Fortschreibung von Bestandsveränderungen liefert.
Zwischen Anpassungs- und Veränderungsdruck : Klimafolgenanpassung und nachhaltige Transformation
(2015)
Strategien der Klimafolgenanpassung und der nachhaltigen Entwicklung werden in Deutschland kaum aufeinander bezogen. Kurzfristige Maßnahmenplanungen zur Schadensbegrenzung dominieren das politische Handeln, Fragen nach Vorsorge- und Gerechtigkeitsaspekten kommen zu kurz. Die Entwicklung resilienter Entwicklungspfade stellt eine Herausforderung für die real existierende Problembewältigung dar. Für die Umsetzung einer nachhaltigen und resilienten Klimaanpassungsstrategie ist ein Mix aus institutionell basierten Regeln und teilhabeorientierten Realexperimenten zur Erprobung von Neuem naheliegend.
The CO2 utilisation is discussed as one of the future low-carbon technologies in order to accomplish a full decarbonisation in the energy intensive industry. CO2 is separated from the flue gas stream of power plants or industrial plants and is prepared for further processing as raw material. CO2 containing gas streams from industrial processes exhibit a higher concentration of CO2 than flue gases from power plants; consequentially, industrial CO2 sources are used as raw material for the chemical industry and for the synthesis of fuel on the output side. Additionally, fossil resources can be replaced by substitutes of reused CO2 on the input side. If set up in a right way, this step into a CO2-based circular flow economy could make a contribution to the decarbonisation of the industrial sector and according to the adjusted potential, even rudimentarily to the energy sector.
In this study, the authors analyse potential CO2 sources, the potential demand and the range of applications of CO2. In the last chapter of the final report, they give recommendations for research, development, politics and economics for an appropriate future designing of CO2 utilisation options based upon their previous analysis.
In diesem Artikel erläutert Michael Kopatz, warum Projekte kooperativen Wirtschaftens (wie beispielsweise Regionalwährung, Tauschringe und Energiegenossenschaften) ihr wahres Potenzial in puncto Klimaschutz, Ressourcenschonung und lokaler Wertschöpfung erst dann entfalten können, wenn Kommunen sie systematisch unterstützen.
Er fordert, dass Projekte der Gemeinwohlökonomie nicht länger nur wohlwollend von politischen Entscheidungsträger(inne)n wahrgenommen werden, sondern dass ein Handlungskonzept zur systematischen Förderung geschaffen wird - eine Wirtschaftsförderung 4.0 sozusagen, die er in seinem Beitrag beispielhaft entwickelt und erläutert.
A reduction in working hours is being considered to tackle issues associated with ecological sustainability, social equity and enhanced life satisfaction - a so-called triple dividend. With respect to an environmental dividend, the authors analyse the time use rebound effects of reducing working time. They explore how an increase in leisure time triggers a rearrangement of time and expenditure budgets, and thus the use of resources in private households. Does it hold true that time-intensive activities replace resource-intensive consumption when people have more discretionary time at their disposal? This study on environmental issues is complemented by introducing the parameters of voluntary social engagement and individual life satisfaction as potential co-benefits of rebound effects. In order to analyse the first dividend, a mixed methods approach is adopted, enabling two models of time use rebound effects to be applied. First, semi-standardised interviews reveal that environmentally ambiguous substitutions of activities occur following a reduction in working hours. Second, estimates for Germany from national surveys on time use and expenditure show composition effects of gains in leisure time and income loss. For the latter, we estimate the marginal propensity to consume and the marginal propensity to time use. The results show that time savings due to a reduction in working time trigger relevant rebound effects in terms of resource use. However, both the qualitative and quantitative findings put the rebound effects following a reduction in working time into perspective. Time use rebound effects lead to increased voluntary social engagement and greater life satisfaction, the second and third dividends.
For 20 years, the number of resource policy approaches with direct and indirect relations to raw materials, resource and material efficiency has grown enormously at national and international level. This discussion paper makes an inventory of different political and regulatory approaches that contain a direct or indirect reference to resources such as construction materials, industrial minerals, or metals. They are examined and evaluated regarding foci and resource priorities as well as further categories such as target lines, governance levels, indicators used, integration into wider target systems, specification, and implementation. The aim is to provide an overview of the spectrum of resource objectives in international, European, and national strategies, programs, and initiatives. The closer analysis of raw material targets embedded in the policy programs and legal approaches reveals that most goals lack a time frame and a concrete vision, thus remain at a strategic level. To complement the overview, the state of research in the field of modeling and simulation is briefly discussed. Concluding remarks concerning their relation to the objectives identified and the task of target setting complete the discussion.
Consumption-based CO2 emissions, which are commonly calculated by means of environmentally extended input-output analysis, are gaining wider recognition as a way to complement territorial emission inventories. Although their use has increased significantly in the last years, insufficient attention has been paid to the methodological soundness of the underlying environmental extension. This should follow the internationally agreed accounting rules of the System of Environmental-Economic Accounting, which addresses the activities undertaken by the residents of a country, independent from where these take place. Nonetheless, some footprint calculations use extensions that account for all the activities within the territory, which leads to methodological inconsistencies. Thus, this article introduces the most relevant conceptual differences between these accounting frameworks and shows the magnitude of the gap between them building on the data generated for the EXIOBASE model. It concludes that the differences are high for many countries and their magnitude is increasing over time.
Dauerplastik
(2015)
Das Deutsche Zentrum für Luft- und Raumfahrt (DLR) hat gemeinsam mit dem Wuppertal Institut für Klima, Umwelt, Energie in der Studie "STROMbegleitung" Technologien, Perspektiven und Ökobilanzen elektrifizierter PKW untersucht. Die Studie gibt einen umfassenden Einblick in den aktuellen Stand der Technik, identifiziert Trends und analysiert die Ökobilanz unterschiedlicher Fahrzeugkonzepte. Gleichzeitig ordnet sie die deutschen Aktivitäten im Bereich Elektromobilität in einen globalen Kontext ein.
The paper reflects the hypothesis that those technological and institutional innovations survive which extend the safe operating range (SOR) of the Humans-Technologies-Institutions (HTI) system (e.g. companies, cities, regions and countries). The multidimensional SOR of a country comprises in particular safe livelihood, quality of life, security, monetary stability, supply security and quality of the environment. A "mechanism of progress" is described involving the search for higher safety and independence of constraints. With innovation and learning in a key role, the mechanism leads to a relative decoupling of resource use and economic value added and a growing share of knowledge generation in the economy. Competition of HTI systems for scarce resources may lead to independence strategies such as enhanced resource efficiency. It may also lead to cooperation of competing HTI systems facilitated by new institutions thus forming an HTI system at higher level of complexity. While the consortium could coordinate their resource consumption within the boundaries of safe operating space, the partner HTI systems would further expand their SOR. Data is provided that net resource importing countries have developed higher material productivity thus increasing their independence from resource supply, and countries with such capability have gained higher innovation capacity.
A lack of proper treatment infrastructure and sufficient capacity for municipal solid waste (MSW) treatment is a crucial barrier for the environmentally sound management of waste. However, overcapacities, especially for waste incineration, also have to be taken into account regarding their potential impacts on recycling markets and waste treatment prices. This paper provides a comprehensive overview of existing MSW incineration plants and their capacities within Europe. In combination with the analysis of imports and exports of MSW for incineration, it provides an indication of over- and undercapacities for incineration plants. Among other things, the results show that in six of the 32 countries analysed in this study, capacities exceed more than 50% of the annual waste generation, while in two countries the total amount of waste generated annually is not enough to fill all the incineration plants.
Politikinstrumente zur Umsetzung von Rücknahmesystemen im Bereich Elektroaltgeräte : Kurzanalyse
(2014)
In der Kurzanalyse wird die Mehrwertsteuer zunächst im Kanon der Steuerarten eingeordnet und die zentralen Gesetzesgrundlagen für die derzeitige Systematik und Differenzierungsvarianten dargestellt. Es werden ressourcenrelevante Mehrwertsteuer-Eingruppierungen mit Änderungsbedarf aufgezeigt und Vereinfachungen beziehungsweise Angleichungen vorgeschlagen. Die Implementationshürden einer solchen Reform und der sich ergebende Forschungsbedarf werden skizziert.
The bioeconomy is gaining growing attention as a perceived win-win strategy for environment and economy in the EU. However, the EU already has a disproportionately high global cropland footprint compared to the world average, and uses more cropland than domestically available to supply its demand for agricultural products. There is a risk that uncontrolled growth of the bioeconomy will increase land use pressures abroad. For that reason, a monitoring system is needed to account for the global land use of European consumption. The aim of this paper is to take a closer look at the tools needed to monitor global cropland footprints, as well as the targets needed to benchmark development. This paper reviews recent developments in land footprint accounting approaches and applies the method of global land use accounting to calculate the global cropland footprint of the EU-27 for the years between 2000 and 2011. It finds a slight decrease in per capita cropland footprints over the past decade (of around 1% annually, reaching 0.29 ha/cap in 2011) and advocates promoting a further decrease in per capita cropland requirements (of around 2% annually) to reach global land use targets for keeping consumption within the safe operating space of planetary boundaries by 2030. It argues that strategic land reduction targets may still go hand in hand with the growth of a smart, innovative and sustainable bioeconomy by reinforcing the need for policies that support greater efficiency across the life-cycle and reduce wasteful and excessive consumption practices. Recommendations for further improving land footprint accounting are given.
The transition towards a circular economy is high on the political agenda and support for innovative business models can be seen as one of the key strategies for its implementation. Nevertheless most of these business models rely on an increasing generation of waste and thus undermine the prevention of waste as top of the waste hierarchy. The paper aims to link this debate to more systemic eco-innovations that offer economic market potentials by reduced material inputs and waste generation. This directs the attention to sufficiency strategies that surpass the level of individual consumer choices and regards the potentials of entrepreneurial sufficiency strategies. It takes the example of waste contracting modelsin Germany as a possible approach of resource-light business models that provide existing utility aspects with altered consumption patterns and decreased resource consumption. It describes environmental and economic benefits and draws conclusions on necessary policy framework conditions.
Einsparpotenziale beim Kunststoffeinsatz durch Industrie, Handel und Haushalte in Deutschland
(2015)
Die Produktion von Kunststoffen ist eine Geschichte extremen Wachstums: waren es global 1950 noch 1,7 Millionen, sind es 2012 weltweit 288 Millionen Tonnen (Mt). 57 Mt davon werden in der EU erzeugt mit einem gleichzeitigen Abfallvolumen von 25 Mt. Einher gehen hohe Verbräuche fossiler Rohstoffe mit entsprechenden Umweltbelastungen und massiven Schäden, die durch Plastikmüll verursacht werden. Das Wuppertal Institut hat im Auftrag des Naturschutzbunds Deutschland (NABU) untersucht, wie sich dieser Wachstumstrend in Deutschland ohne Gegensteuerung fortsetzen wird und mit welchen Strategien die Plastikflut eingedämmt werden kann. Die Autoren der Studie errechneten einen Steigerung um 28 Prozent bis zum Jahr 2030, insbesondere in den Bereichen Verpackungen und Bau. Für die künftig wichtigsten Anwendungsbereiche wurden in der Studie jeweils drei konkrete Ansätze zur Verringerung des Kunststoffeinsatzes aus den Bereichen Industrie, Handel und Haushalte ausgewählt. Diese neun Optionen wurden an Fallbeispielen auf ihre Vor- und Nachteile und die grundsätzliche technische, rechtliche und ökonomische Machbarkeit hin diskutiert. Umsetzungsansätze liefert die Studie für den politischen Raum, für Unternehmen und den privaten Konsum.
Im vorliegenden Beitrag soll die Rolle suffizienter Geschäftsmodelle in der Abfallwirtschaft aufgezeigt und anhand konkreter Fallbeispiele diskutiert werden. Daraus lassen sich Schlussfolgerungen zur Rolle technischer Pfadabhängigkeiten, zur Messbarkeit von Suffizienz und zur Integration von Suffizienzaspekten in der Infrastrukturplanung ziehen, die über abfallwirtschaftliche Geschäftsmodelle hinausgehen.
A future-oriented and sustainable "Leasing Society" is based on a combination of new and innovative serviceoriented business models, changed product and material ownership structures, increased and improved eco-design efforts, and reverse logistic structures. Together these elements have the potential to change the relationship between producers and consumers, and thereby create a new incentive structure in the economy regarding the use and re-use of resources. While the consumer in a leasing society buys a service (instead of a product), the producer in a leasing society retains the ownership of the product (instead of selling it) and sells the service of using the product. This creates producer incentives to re-use, remanufacture, and recycle products and materials and could become a cornerstone of the circular economy, depending on how the leasing society is implemented. While a predominantly positive picture of the success of a leasing society model and related business cases emerges from the bigger part of the available literature, this paper argues that the resource efficiency of respective business cases is highly dependent on the specific business case design. This paper develops a more cautious and differentiated definition of the leasing society by discussing relevant mechanisms and success factors of leasing society business cases. The leasing society is discussed from a micro business-oriented and a macro environment-oriented perspective complemented by a discussion of conditions for successful business models that reduce environmental impacts and resource footprints.
Im Auftrag des Bundesforschungsministeriums hat das Wuppertal Institut eine Studie zur systemischen Betrachtung und Modellierung der Bioökonomie erstellt. Sie zeigt Wege auf, die komplexen sozio-ökonomischen Zusammenhänge und Umweltauswirkungen der Bioökonomie zu erfassen und soll als Grundlage für den Aufbau eines kontinuierlichen Monitorings dienen. Die Autor(inn)en erfassten Indikatoren und Modellierungsmethoden mit Bezug zur Bioökonomie und weisen auf bestehende Lücken hin: Diese finden sich vor allem bei der Erfassung neuer technologiegetriebener Sektoren, der systemischen Betrachtung eines nachhaltigen Konsums und bei der Modellierung der Zusammenhänge zwischen Innovationen, Wirtschaftswachstum und Ressourcenverbrauch (insbesondere die Landnutzung).
Zur Umsetzung eines systemischen Monitorings empfiehlt die Studie das folgende Vorgehen: Unter Zuhilfenahme des DPSIR-Konzeptes (Analyse von Wirkungsbeziehungen nach Driving forces, Pressures, States, Impacts und Responses) sollten Schlüsselindikatoren und Nachhaltigkeitsziele in einem Indikatoren-"Dashboard" zusammengeführt werden. Benötigt wird zudem ein Werkzeugkasten von Methoden, der vor allem integrierte Analyse- und Bewertungsmodelle sowie ein systemisch konzipiertes Metamodell umfasst.
In early September 2014, about 4.000 scientists, activists and artists at the 4th International Conference on Degrowth sent out two messages.
1. Industrialized societies will change, either by disaster or by design. Accelerated resource exploitation and climate change can force societies into a transition. Or they swiftly develop new forms of economic, political and social organization which respect the planetary boundaries.
2. "Degrowth" has become a new social movement which translates scientific insights into cultural change, political change and social practice. Hence, the conference itself was an experiment on the potentials and limits of share economy, commoning and sufficiency.
A team of young scholars and activists from different German research institutes and non-govern- mental organisations prepared the conference. The team of the Wuppertal Institute was partly involved in the preperation of the conference. Scientists from all research groups took part in the conference, presenting and discussing project results.
The publication is a collection of contributions of the Wuppertal Institute to the conference and covers pivotal issues of the degrowth-debate: indicator development (Freyling & Schepelmann), working time reduction (Buhl), feminist theory (Biesecker & Winterfeld), and urban transition (Best).
Umweltverträglichkeitsprüfung und strategische Umweltprüfung als Instrumente des Ressourcenschutzes
(2014)
Vor dem Hintergrund der aktuellen Ressourcenschutzdiskussion wird im Beitrag erläutert, wie Ressourcenschutzbelange in den bestehenden UVPG-Schutzgütern, aber auch darüber hinaus in der Umweltprüfung stärker berücksichtigt werden können. In diesem Zusammenhang stellen die räumlichen und zeitlichen Systemgrenzen der Umweltprüfung eine besondere Herausforderung dar. Es werden erste Ansätze dargestellt, wie ressourcenbezogene Umweltwirkungen und stoffliche und energetische Inanspruchnahmen in die Planungspraxis übernommen werden können.
Many countries have started to develop policy programs for the sustainable use of natural resources. Indicators and targets can cover both a territorial and a life-cycle-wide global perspective. This article focuses on how a safe operating space for global material resource use can be outlined based on existing economy-wide material flow indicators. It reflects on issues such as scale and systems perspective, as the choice of indicators determines the target "valves" of the socio-industrial metabolism. It considers environmental pressures and social aspects of safe and fair resource use. Existing proposals for resource consumption targets are reviewed, partially revisited, and taken as a basis to outline potential target values for a safe operating space for the extraction and use of minerals and biomass by final consumption. A potential sustainability corridor is derived with the Total Material Consumption of abiotic resources ranging from 6 to 12 t/person, the Total Material Consumption of biotic resources not exceeding 2 t/person, and the Raw Material Consumption of used biotic and abiotic materials ranging from 3 to 6 t/person until 2050. For policy, a "10-2-5 target triplet" can provide orientation, when the three indicators are assigned values of 10, 2, and 5 t/person, respectively.
Ziel dieser Studie ist es, einen aktuellen Überblick über den Stand der Recyclingwirtschaft in Deutschland zu geben. Der Fokus liegt dabei vor allem auf den Marktprozessen, die bereits heute ökonomische Anreize zur Schließung von Stoffkreisläufen geben, bzw. auf spezifischen Hemmnissen, die genau solchen Entwicklungen im Wege stehen.
Aufbauend auf der Analyse spezifischer Hemmnisse für einzelne Abfallfraktionen (rechtliche und institutionelle Hemmnisse, Marktmacht, Informationsdefizite etc.) leitet die Studie verschiedene Instrumente und handlungsorientierte Ansätze ab, die zu einer Verbesserung der Kreislaufführung beitragen könnten; dabei kann Deutschland auch von bestehenden Best-Practice-Ansätzen im Ausland profitieren. Dazu gehören unter anderem der verstärkte Einsatz ökonomischer Instrumente, Maßnahmen zur verstärkten Integration von Abfallwirtschaft und Produktionssektor, Urban Mining Konzepte, internationale Vereinbarungen zum Rohstoffrecycling sowie Green Tech Funds.
Measuring progress towards sustainable development requires appropriate frameworks and databases. The System of Environmental-Economic Accounts (SEEA) is undergoing continuous refinement with these objectives in mind. In SEEA, there is a need for databases to encompass the global dimension of societal metabolism. In this paper, we focus on the latest effort to construct a global multi-regional input-output database (EXIOBASE) with a focus on environmentally relevant activities. The database and its broader analytical framework allows for the as yet most detailed insight into the production-related impacts and "footprints" of our consumption. We explore the methods used to arrive at the database, and some key relationships extracted from the database.
A desirable future critically depends on our ability to ensure the supply of key resources while simultaneously respecting planetary boundaries. This paper looks at the potential implications of living within the "safe operating space" for people, business and the economy. It develops a positive vision of the future based on three pillars: a safe and fair use of global resources, a sustainable society, and a transformed economy. We review and build on recent sustainability visions to develop a holistic reflection on what life in 2050 could look like, and explore the key changes in the economy needed to get there. In particular we show that resource efficiency requires a systemic shift in values, innovation, governance and management regimes. We present a bold vision for Europe underlined by indicators and targets, explore transition challenges to getting there and conclude with a list of key policies needed for overcoming challenges and reaching the vision.
This report details current and potential recycling of critical metals in Waste from Electrical Electronic Equipment (WEEE). The term "critical metals" is used instead of "rare metals" because the concept incorporates not only supply but also demand. The EU needs access to these metals and recycling can be an important part of the supply-strategy.
The study shows that the current recycling of critical metals in WEEE is very low, but that the potential amount could be increased threefold within 2015. Improving of the recycling of critical metals requires a variety of initiatives tackling different week point in the overall process: better collection, better pre-processing and end-processing, limiting the export of WEEE or used products out of the EU and better design of the EEE-products.
This study shows that data on sales volumes, WEEE composition and the composition of critical metals in EEE is currently insufficient for detailed analysis and monitoring, and addressing this should be a priority. Further, more detailed information on components used in EEE product groups would enable recyclers to identify and access the most materially important components. Dialog between recyclers, smelters and manufacturers could also facilitate product design that supports the recycling process.
Critical metals are in great demand by the electrical and electronics industry, so waste electrical and eletronic equipment represents a significant source of secondary raw materials. Owing to low recycling rates and the concomitant supply risks associated with critical metals, the closure of the material cycles is highly relevant to the German economy. Losses of these metals occur from collection until their material recovery, along the entire disposal chain of waste electrical and electronic equipment. This paper develops planning criteria for the design of collection groups to achieve higher recovery amounts of such metals. The aim is to clarify what amounts of metals exist, both product-specific and on the market, how the dismantling of the products is constructed and how collection groups can be arranged with planning criteria oriented towards resource conservation. The analysis is a snapshot using the example of indium and selected products. A procedure is presented and findings identified which are transferable to various critical metals and to waste electrical and electronic equipment. The results show that grouping of products according to resource amounts and the dismantling effort enables forward-looking and resource-efficient planning of the treatment of every single collection group.
Ein sorgsamer Umgang mit natürlichen Ressourcen gehört zu den Kernthemen von Industrial Ecology. Mit der jeweiligen Betrachtungsebene, vom Unternehmen bis zur globalen Ebene, wechseln die Herausforderungen, Methoden und Lösungsansätze. Gibt es auch Indikatoren, die skalenübergreifend angewandt werden können?
Shifting the resource base for chemical and energy production from fossil feedstocks to renewable raw materials is seen by many as one of the key strategies towards sustainable development. The utilization of biomass for the production of fuels and materials has been proposed as an alternative to the petroleum-based industry. Current research and policy initiatives focus mainly on the utilization of lignocellulose biomass, originating from agriculture and forestry, as second generation feedstocks for the production of biofuels and electricity. These activities act on the assumption that significant amounts of biomass for non-food purposes are available. However, given a certain productivity per area, the current massive growth in global biofuels demand may in the long term only be met through an expansion of global arable land at the expense of natural ecosystems and in direct competition with the food-sector. Although many studies have shown the potential of biofuels production to reduce both, greenhouse gas emissions and non-renewable energy consumption, these production routes are still linear processes which depend on significant amounts of agricultural or forestry production area. Cascading use, i.e. when biomass is used for material products first and the energy content is recovered at end-of-life, may provide a greater environmental benefit than primary use as fuel. Considering waste and production residues as alternative feedstocks could help to further reduce pressures on global arable land. This research focused on thermochemical and biochemical technologies capable of utilizing organic waste or forestry residuals for energy, chemical feedstock, and synthetic materials (polymers) generation. Routes towards synthetic materials allow a closer cycle of materials and can help to reduce dependence on either fossil or biobased raw materials. The system-wide environmental burdens of three different technologies, including (1) municipal solid waste (MSW) gasification followed by Fischer-Tropsch synthesis (FTS), (2) plasma gasification of construction and demolition (C&D) wood for syngas production with energy recovery, and (3) forest residuals use in a biorefinery for polyitaconic acid (PIA) production, were assessed using life-cycle assessment. The first two studies indicated that MSW gasification and subsequent ethylene and polyethylene production via FTS has lower environmental impacts than conventional landfilling. In the future, as societies may shift towards the use of renewable energy, power offset by conventional waste-to-energy systems would not be as significant and chemicals production routes may then become increasingly competitive (in terms of environmental burdens) also to waste incineration. While production cost of Fischer-Tropsch derived chemicals seems not yet competitive to fossil-based chemicals provision, future price increases in global oil prices as well as changes in waste tipping fees, and efficiency gains on site of the waste conversion systems, may alter the economics and allow carbon recycling routes to reach a price competitive to fossil-based production routes. The third study found that plasma gasification of C&D wood for energy recovery has roughly similar environmental impacts than conventional fossil-based power systems. However, process optimization with respect to coal co-gasified, coke used as gasifier bed material, and fuel oil co-combusted in the steam boiler, would allow to significantly lower the system-wide environmental burdens. The fourth study looked at PIA production from softwood hemicellulose in a stream integrated approach (with the partially macerated wood and lignin being used in other existing processes such as pulp & paper plants for conventional pulp and bioenergy production). The assessment indicated lower global warming potential, energy demand, and acidification, for the wood-based PIA polymer, when compared to corn-based PIA and fossil-based polyacrylic acid (PAA). However, water use associated with wood-derived PIA was found to be higher than for fossil-based PAA production and land occupation is highest for the wood-derived polymer. It is hoped that results of this dissertation will add to the current debate on sustainable waste and biomass utilization and to establish future supply chains for green and sustainable chemical products.
Für die Umsetzung der Energiewende und speziell den Ausbau erneuerbarer Energien sind nicht nur energiewirtschaftliche oder Klimaschutz-Kriterien maßgeblich. Zu einer umfassenden Nachhaltigkeitsbewertung gehört unter anderem auch die Ressourcenbewertung. Hier ist unstrittig, dass die Gesamt-Ressourceninanspruchnahme eines Energiesystems generell erheblich niedriger ist, wenn dieses nicht auf fossilen, sondern auf erneuerbaren Energien basiert (und dabei nicht hauptsächlich auf Biomasse ausgerichtet ist). Bisher wurde jedoch insbesondere der Verbrauch und die langfristige Verfügbarkeit der mineralischen Rohstoffe, die in der Regel zur Herstellung von Energiewandlern und Infrastruktur benötigt werden, wenig untersucht.
Im Rahmen des Projekts KRESSE wurde daher erstmals analysiert, welche "kritischen" mineralischen Rohstoffe für die Herstellung von Technologien, die Strom, Wärme und Kraftstoffe aus erneuerbaren Energien erzeugen, bei einer zeitlichen Perspektive bis zum Jahr 2050 in Deutschland relevant sind. Die Einschätzung als "kritisch" umfasst dabei die langfristige Verfügbarkeit der identifizierten Rohstoffe, die Versorgungssituation, die Recyclingfähigkeit und die Umweltbedingungen der Förderung. Die Studie macht deutlich, dass die geologische Verfügbarkeit mineralischer Rohstoffe für den geplanten Ausbau der erneuerbaren Energien in Deutschland grundsätzlich keine limitierende Größe darstellt. Dabei kann jedoch möglicherweise nicht jede Technologievariante unbeschränkt zum Einsatz kommen.
The availability of life cycle inventories is one of the biggest challenges for life cycle wide environmental assessment. There are several life cycle assessment (LCA) databases providing inventory data as well as resource and emission profiles of processes for impact assessment methods like ReCiPe or IMPACT 2002+. But the use of these LCA databases for input oriented environmental assessment is very limited as they cover only a part of all relevant input flows. The paper describes current challenges when calculating the input oriented Material Input per Service Unit (MIPS) indicators based on LCA inventory data from the Ecoinvent database. Propositions are made how to address these challenges. As a conclusion, further need of research to reach a full compatibility of LCA databases and the MIPS concept is pointed out.
Crowdsourcing as a method of transdisciplinary research : tapping the full potential of participants
(2014)
Within the scope of citizen science projects, crowdsourcing has already expanded into scientific application areas. In this, its scientific potential is only partly exhausted, however.
It will be shown that transdisciplinary research is made up in content and structural aspects in such a way that crowdsourcing can fully unfold as a research method through varied participation possibilities, reflective processes and use of contemporary technical possibilities. Furthermore, mutual learning, understanding and the dissemination of knowledge strongly profits from effects that even result automatically in this context.
The scientific application of crowdsourcing represented here makes high demands on project management, but it is expected to turn out as an effective research method precisely in the area of transdisciplinary research.
EXIOPOL (A New Environmental Accounting Framework Using Externality Data and Input–Output Tools for Policy Analysis) was a European Union (EU)-funded project creating a detailed, global, multiregional environmentally extended Supply and Use table (MR EE SUT) of 43 countries, 129 sectors, 80 resources, and 40 emissions. We sourced primary SUT and input–output tables from Eurostat and non-EU statistical offices. We harmonized and detailed them using auxiliary national accounts data and co-efficient matrices. Imports were allocated to countries of exports using United Nations Commodity Trade Statistics Database trade shares. Optimization procedures removed imbalances in these detailing and trade linking steps. Environmental extensions were added from various sources. We calculated the EU footprint of final consumption with resulting MR EE SUT. EU policies focus mainly on energy and carbon footprints. We show that the EU land, water, and material footprint abroad is much more relevant, and should be prioritized in the EU's environmental product and trade policies.
The European Waste Framework Directive has defined waste prevention as top of the waste hierarchy meaning nothing less than a fundamental change of the sociotechnical system of waste infrastructures with all its economic, legal, social and cultural elements. Based on an empirical analysis of more than 300 waste prevention measures this paper assesses which prevention effects can realistically be achieved by applying the measures described in the German waste prevention programme or in those of other EU member states. Taking into account waste streams like packaging, food waste, bulky waste and production waste the results show that waste generation is not an unavoidable evil but can be significantly reduced at current level of technology.

Anpassung an regionale Klimafolgen kommunizieren : Konzepte, Herausforderungen und Perspektiven
(2014)
Der Klimawandel ist nicht nur ein globales Problem, sondern wird auch konkrete Folgen für die Menschen in Deutschland haben. Nur wenn es gelingt, die zukünftigen Klimaveränderungen und ihre voraussichtlichen Folgen zu kommunizieren, ist eine rechtzeitige Anpassung möglich. Nur dann können Gefahren minimiert und Chancen genutzt werden. Wie aber kann vermittelt werden, dass die Anpassung an Klimafolgen notwendig ist - obwohl unbekannt ist, welches Ausmaß die Klimaveränderungen und die Folgen in der Region haben werden? Bei wem führen eher moralische und bei wem eher nutzenorientierte Argumente zu erhöhter Handlungsbereitschaft? Welche Kommunikationsmethoden eignen sich für welche Zielgruppen? Wie können Jugendliche für das Zusammenspiel von Klimaschutz und Anpassung sensibilisiert werden? Fundierte Theorieansätze und zahlreiche Praxisberichte erschließen den vergleichsweise neuen Aufgabenbereich "Klimaanpassungskommunikation". Eine steckbriefhafte Zusammenstellung von erprobten Instrumenten und Formaten illustriert, welche Maßnahmen Erfolg versprechen.
Große Anteile der Gesamtnachfrage nach kritischen Metallen werden durch die Elektro- und Elektronikindustrie verantwortet, weshalb diese Geräte eine bedeutende Sekundärrohstoffquelle darstellen. Bei auffallend niedrigen Recyclingquoten und gleichzeitigen Versorgungsrisiken kritischer Metalle nimmt die Schließung dieser Stoffkreisläufe eine wichtige Stellung für die deutsche Wirtschaft ein. Die Verluste der Metalle treten von der Sammlung bis zum Materialrecycling entlang der gesamten Entsorgungskette der Elektro- und Elektronikaltgeräte auf.
Gegenstand dieser Arbeit ist es, Kriterien für die Gestaltung der Sammelgruppenstruktur der Geräte zu entwickeln und damit erhöhte Rückgewinnungsmengen solcher Metalle erreichen zu können. Ziel ist es zu klären, welche produktspezifischen, in Verkehr gebrachten und erfassbaren Ressourcen-Mengenpotenziale existieren, wie sich die Demontagefähigkeit der Produkte gestaltet und wie sich mit diesen ressourcenschutzorientierten Planungskriterien die Sammelgruppen strukturieren lassen. Die Untersuchung erfolgt als Momentaufnahme am Beispiel von Indium und ausgewählter Produkte. Damit wird eine Vorgehensweise aufgezeigt und Erkenntnisse herausgearbeitet, die modellhaft auf sämtliche kritische Metalle und Elektro- und Elektronikaltprodukte übertragbar sind.
Insgesamt wird in den Ergebnissen deutlich, dass mit einer Gruppierung der Produkte nach Ressourcen-Mengenpotenzial und Demontagefähigkeit der in Verkehr gebrachten Geräte eine vorausschauende und ressourceneffiziente Planung der Behandlungswege der einzelnen Sammelgruppen ermöglicht wird.
The current flow of carbon for the production, use, and waste management of polymer-based products is still mostly linear from the lithosphere to the atmosphere with rather low rates of material recycling. In view of a limited future supply of biomass, this article outlines the options to further develop carbon recycling (C-REC). The focus is on carbon dioxide (CO2) capture and use for synthesis of platform chemicals to produce polymers. CO2 may be captured from exhaust gases after combustion or fermentation of waste in order to establish a C-REC system within the technosphere. As a long-term option, an external C-REC system can be developed by capturing atmospheric CO2. A central role may be expected from renewable methane (or synthetic natural gas), which is increasingly being used for storage and transport of energy, but may also be used for renewable carbon supply for chemistry. The energy input for the C-REC processes can come from wind and solar systems, in particular, power for the production of hydrogen, which is combined with CO2 to produce various hydrocarbons. Most of the technological components for the system already exist, and, first modules for renewable fuel and polymer production systems are underway in Germany. This article outlines how the system may further develop over the medium to long term, from a piggy-back add-on flow system toward a self-carrying recycling system, which has the potential to provide the material and energy backbone of future societies. A critical bottleneck seems to be the capacity and costs of renewable energy supply, rather than the costs of carbon capture.
The relationship between large-scale metal mining and its impacts is a topic of growing discussions in Argentina. Multinational mining corporations publish sustainability reports in order to show their social responsibility and contributions to sustainable development. These reports promote a higher transparency but doubts remain as to its usefulness to improve relationships with communities. By using a descriptive-explanatory method, this study analyses the 2009 Sustainability Report of Bajo de la Alumbrera mine so as to assess its quality and compare the "reality" painted by the company with the views of conflict by critical stakeholders. Results, validated with reports from other years, show the need to improve the information reported for conflictive indicators and, along with local governments, to implement a significant change in the way of making decisions, especially by engaging critical stakeholders.
Global warming, the overall extraction of minerals and the expansion of cultivated land for biomass harvest are growing globally. These "Big Three" represent key environmental pressures which may lead to a continuous degradation of the living environment, if not controlled at levels with acceptable low risk. The situation is complex, because countries and regions consume products which require resources such as minerals and land in various parts of the world. Nevertheless, it is possible to measure the global resource use which is associated with the domestic consumption. In order to inform policies at the national and supranational level whether it may be necessary to adjust the incentive framework for industry and households, reference data are needed to compare the status quo of their countries with what may be deemed acceptable at a global level. This chapter outlines a rationale for the derivation of possible long-term targets for total material consumption of abiotic materials (TMCabiot) and global land use for crops (GLUcropland). The indicated targets are expressed in tentative per capita values which may serve as a first orientation and basis for further debate and research.
While strategic studies on natural resources usually focus on the criticality of certain single materials, our paper starts from the inter-linkages between and among resources (called "the resource nexus"). It examines the impact any food and water stress may have on extraction activities in fragile states and regions. According to our approach, conflicts are likely to increase and may escalate in a number of countries, many of which are of relevance for the global supply of strategic materials. Future criticality for European and other industries, thus, is more likely to result from particular regions surpassing their adaptive capacities, and not mainly from limited availability or bottlenecks in the supply chain. The paper first develops a heuristic model of drivers for stress in resource-rich regions. Applying this approach, our paper then develops a global three-layered map along the dimensions of (i) future regional food and water stress, (ii) fragility of countries, and (iii) resource-rich countries with relevant reserves of strategic materials. As a result our paper tentatively identifies 15 countries at high risk and some 30 other countries being at relevant risk of causing resource supply disruptions. The conclusions underline the need to analyse those global inter-linkages and institutional mechanisms for strategic futures studies at a regional scale. As this may go beyond the capacities of actors on commodity markets, our paper also draws conclusions towards the establishment of an international data hub on the global resource nexus and for futures research. The paper points to some of the long-term implications of these issues.
Improving material efficiency in the manufacturing industry is a sustainability imperative for companies due to economic and environmental advantages such as the reduction of material costs and resource use. Innovative solutions in terms of material efficiency measures are diverse and widespread. As a systematic assessment of efficiency approaches and their effects are likely to support dissemination and deployment, this paper aims to develop an approach that helps to classify material efficiency measures. The classification approach presents different dimensions and properties of material efficiency measures based on a literature analysis regarding existing classification approaches as well as on work that has been conducted for the Eco-Innovation Observatory. The classification has been designed as basis for an empirical impact assessment of material efficiency measures based on a data sample that stems from the German Material Efficiency Agency.
Emscher 3.0 : der Emscher-Umbau als Vorbild für die Gestaltung zukunftsfähiger Infrastrukturen
(2013)
Based on the European Waste Framework Directive and the German Recycling Management Act of 01.06.2012 the objectives for a national waste prevention programme were defined. As main objective, according to art. 1 WFD, the "prevention or reduction of the disadvantageous impacts of waste generation and management on the human health and the environment" is recommended. Indicators for a quantitative and qualitative monitoring are derived for both, the individual measures as well as for a waste prevention programme.
Carbon recycling, in which organic waste is recycled into chemical feedstock for material production, may provide benefits in resource efficiency and a more cyclical economy - but may also create "trade-offs" in increased impacts elsewhere. We investigate the system-wide environmental burdens and cost associated with carbon recycling routes capable of converting municipal solid waste (MSW) by gasification and Fischer-Tropsch synthesis into ethylene. Results are compared to business-as-usual (BAU) cases in which ethylene is derived from fossil resources and waste is either landfilled with methane and energy recovery (BAU#1) or incinerated (BAU#2) with energy recovery. Monte Carlo and sensitivity analysis is used to assess uncertainties of the results. Results indicate that carbon recycling may lead to a reduction in cumulative energy demand (CED), total material requirement (TMR), and acidification, when compared to BAU#1. Global warming potential is found to be similar or slightly lower than BAU#1 and BAU#2. In comparison to BAU#2, carbon recycling results in higher CED, TMR, acidification, and smog potential, mainly as a result of larger (fossil-based) energy offsets from energy recovery. However, if a renewable power mix (envisioned for the future) is assumed to be offset, BAU#2 impacts may be similar or higher than carbon recycling routes. Production cost per kilogram (kg) MSW-derived ethylene range between US$1.85 and US$2.06 (Jan 2011 US$). This compares to US$1.17 per kg for fossil-based ethylene. Waste-derived ethylene breaks even with its fossil-based counterpart at a tipping fee of roughly US$42 per metric ton of waste feedstock.
Calculating MIPS 2.0
(2013)
The Wuppertal Institute developed, in the early 1990s, an input-oriented lifecycle-wide resource accounting method, the "Material Input per Service-Unit" concept (MIPS), today also referred to as "Material Footprint". The official handbook applicable to products, services, and processes describes a MS Excel-based sequential approach for calculating MIPS. Today's computing power, available to every researcher, and access to software and databases dedicated to lifecycle analysis make calculating MIPS using matrix inversion possible. This also opens up possibilities for enhancing MIPS-models programmatically: parameterizing the foreground and background systems, batch modeling for producing time series, and computational algorithms enhancing interpretation. The article provides (1) an overview of the methods and tools used for calculating MIPS from its origins to today, and (2) demonstrates some of the programmatically enhanced capabilities offered to MIPS-practitioners.
Emscher 3.0 : from grey to blue - or, how the blue sky over the Ruhr region fell into the Emscher
(2013)
The river Emscher is - similar to the river Ruhr - the symbol of one of the internationally most renowned industrial regions: the Ruhr area with its 5 million inhabitants and an important location of key industries such as steel, chemical and materials industry. The revitalisation of the Emscher over the last 20 years marks a new phase in the region's history and is an impressive example of ecological and socio-economic transformation affecting all aspects of life along the river. What can we learn from the Emscher conversion for upcoming tasks in other infrastructure fields?
Several studies in Germany aimed at the development of a sound database on existing waste prevention measures by public bodies at the local, regional and federal levels. These results are the starting point for the creation of a national prevention program, which has to be presented by all European Member States until the end of 2013 - due to the revised European Waste Framework Directive. Based on this empirical foundation, this paper draws conclusions with regard to drivers and barriers for eco-innovations in the field of waste prevention. The analysis shows that an optimized adaptation of information on waste prevention to the needs of specific target groups is still missing but could be a relevant driver. With regard to barriers the results of the study show that waste prevention is by no means always a win–win-situation. Institutional frameworks are missing to coordinate the different interests and for the exchange of experiences that could help to realize learning effects regarding innovation approaches.
This chapter addresses material leakage as a major problem of international open markets for used goods, in particular for used vehicles. It develops elements of an international metal covenant that should allow for a more sustainable management of global material flows in that area. The arguments in favour of such a proposal are as follows: Any regulation should actively seek for industry participation, taking advantage of business interest in supplying a sufficient amount of materials while lowering materials cost. It should also address public issues such as sustainability of recycling and waste. A first section analyses contracts as a tool to overcome knowledge problems that occur when many actors are involved. A second short section gives empirical evidence for material leakage in the case of used vehicles from Germany. A third section develops elements of an international metal covenant. A fourth section analyses potential impacts and discusses legal and institutional issues. Finally, some conclusions are drawn.
This article presents the accounts of China's Total Material Requirement (TMR) during 1995–2008, which were compiled under the guidelines of Eurostat (2009) and with the Hidden Flow (HF) coefficients developed by the Wuppertal Institute. Subsequently, comparisons with previous studies are conducted. Using decomposition, we finally examine the influential factors that have changed the TMR of China. The main findings are the following: (1) During 1995–2008 China's TMR increased from 32.7 Gt to 57.0 Gt. Domestic extraction dominated China’s TMR, but a continuous decrease of its shares can be observed. In terms of material types, excavation constituted the biggest component of China's TMR, and a shift from biomass to metallic minerals is apparent; (2) Compared with two previous studies on China's TMR, the amounts of TMR in this study are similar to the others, whereas the amounts of the used part of TMR (Direct Material Input, DMI) are quite different as a result of following different guidelines; (3) Compared with developed countries, China's TMR per capita was much lower, but a continuous increase of this indicator can be observed; (4) Factors of Affluence (A) and Material Intensity (T), respectively, contributed the most to the increase and decrease of TMR, but the overall decrease effect is limited.
Indikatoren für ein quantitatives und qualitatives Monitoring werden sowohl für einzelne Maßnahmen als auch für ein Abfallvermeidungsprogramm hergeleitet. Die knapp 300 Maßnahmen zur Abfallvermeidung durch die öffentliche Hand aus der Beispielsammlung des Vorläuferprojektes werden zunächst bewertet und konsolidiert. Entlang der Lebenswegstufen Rohstoffgewinnung, Produktgestaltung, Produktion, Logistik, Handel, Einkauf, Nutzung und Abfallentsorgung werden diese systematisch gruppiert. Das Abfallvermeidungspotenzial und die ökologischen Auswirkungen ausgewählter Einzelmaßnahmen werden orientierend bewertet. Die wesentlichen Effekte werden durch die Vermeidung von Umweltbelastungen bei den "vermiedenen" Produktionsaufwendungen, z.B. durch die intensivere Nutzung und die Verlängerung der Lebensdauer von Produkten, erzielt. Dazu gehört auch die Förderung eines Gebrauchtwarenmarkts zur Wiederverwendung von Waren. Ökonomische und soziale Auswirkungen werden punktuell beschrieben. Basierend auf der Bewertung werden geeignete Abfallvermeidungsmaßnahmen für das nationale Abfallvermeidungsprogramm vorgeschlagen.
The Low Carbon Future Cities (LCFC) project aims at facing a three dimensional challenge by developing an integrated city roadmap balancing: low carbon development, gains in resource efficiency and adaptation to climate change. The paper gives an overview of the first outcomes of the analysis of the status quo and assessment of the most likely developments regarding GHG emissions, climate impacts and resource use in Wuxi - the Chinese pilot city for the LCFC project. As a first step, a detailed emission inventory following the IPCC guidelines for Wuxi has been carried out. In a second step, the future development of energy demand and related CO2 emissions in 2050 were simulated in a current policy scenario (CPS). In parallel, selected aspects of material and water flows for the energy and the building sector were analyzed and modeled. In addition, recent and future climate impacts and vulnerability were investigated. Based on these findings, nine key sectors with high relevance to the three dimensions could be identified. Although Wuxi's government has started a path to implement a low carbon plan, the first results show that, for the shift towards a sustainable low carbon development, more ambitious steps need to be taken in order to overcome the challenges faced.
Nachhaltiges Ressourcen-Management : eine Herausforderung für die Politik und die Wissenschaft
(2013)
Politische und rechtliche Ansätze für inputorientierte Ressourcenziele in Europa und weltweit
(2013)
Defining the prevention of waste as top priority of the waste hierarchy - as confirmed by the revised Waste Framework Directive (WFD) - is much more than a simple amendment of ways to deal with waste, but means nothing less than a fundamental change of the socio-technical system of waste infrastructures and requires a transition from end-of-pipe technologies towards an integrated management of resources. The WFD therefore obligates member states to develop national waste prevention programs as a new policy instrument with the development of waste prevention indicators as one of the core elements. The article discusses the limitations of waste-based key figures and shows the need for more process-oriented indicators. As part of the development of national waste prevention programs such indicators reveal the relevance of different barriers that have to be overcome in order to make prevention an effective top priority in the waste hierarchy. With regard to path dependencies caused by sunk costs in end-of-pipe waste infrastructures the absolute amount of integrated environmental investments, as well as their share of the total waste-related investments, can be seen as indicators for the level of innovation activities aimed at waste prevention. Sector-specific indicators for the production phase could be used as benchmarks and to highlight differences in the need for policy interventions.

Die Bedeutung von Urban Mining nimmt zu, da das Wachstum der Technosphäre, insbesondere des Baubestandes abnimmt. In den kommenden Jahrzehnten wird in Deutschland regional differenziert ein Gleichgewicht zwischen Zu- und Rückbau erreicht werden. Dann wird ein erheblicher Teil des Materialbedarfs aus Recycling gedeckt werden können. Erste Kommunen wie die Stadt Zürich praktizieren ein integriertes Bestands- und Ressourcenmanagement. Auf nationaler Ebene laufen Untersuchungen zur Dynamik des Materiallagers. Die Entwicklung eines Informationssystems Urban Mining bedarf der Kooperation aller Beteiligten.
Europe in transition : paving the way to a green economy through eco-innovation ; annual report 2012
(2013)
Als einer der weltweit führenden Industriestandorte ist Deutschland abhängig von der Versorgung mit Rohstoffen. Aber nur noch wenige Bau- und Massenrohstoffe wie Kies, Sand oder Kalkstein können aus heimischen Lagerstätten gewonnen werden; Industriemineralien, Energierohstoffe und vor allem metallische Rohstoffe müssen in großem Umfang aus dem Ausland eingeführt werden. Strategische Ansätze wie die Ressourcenstrategie der EU oder die Ressourceneffizienzstrategie des BMU setzen daher in zunehmendem Maße auf die Senkung des Primärrohstoffverbrauchs durch den Einsatz von Sekundärrohstoffen und die Erhöhung der Anteile recycelter Abfälle in Produkten - mit massiven Konsequenzen für die Planung abfallwirtschaftlicher Infrastrukturen.

This study aims to investigate whether, to what extent and how a transition toward integrated flood management has taken place in the Dongting Lake area at the middle Yangtze. Accordingly, we conducted a longitudinal research of its flood management (1949–2009). We developed an analytical framework linking regime components to two societal learning types (double and triple-loop learning) that are key to a regime transition. Our study shows that the transition toward integrated flood management has already started, but the whole regime transformation will still take time to complete, due to, for example, the not-yet-ready decision-making processes that shape the structure changes as well as the incompatibilities between what is on paper and real implementation. To understand how the regime transition took place, we investigated where and how triple-loop learning was initiated as well as how so-called "informal learning processes" has contributed to the transition of Dongting flood management.
To achieve an efficient use and allocation of limited water resources and thus resolve increasing water use conflicts due to fast rising societal water demands, in 2000, the Chinese government started a management strategy of 'Construction of a Water Saving Society (WSS)'. It is guided by the principle that socio-economic development should consider the carrying capacity of the ecosystem and focuses on institutional innovation, building on the water rights concept. This paper explores the innovation process during the transition towards WSS by investigating the development course of the innovation process during the transition towards WSS, and the adaptive capacity of the existing water management regime underlying the innovation process. Accordingly, an analysis framework consisting of three types of governance activities and factors determining a regime's adaptive capacity was developed, based on the theory of transition management and adaptive governance. The Tianjin and Zhangye WSS experiments were selected for a deep understanding of local innovations. It is revealed that co-evolution of all three types of governance activities that are claimed to be essential for transition has taken place. However, the current adaptive capacity of the regime still needs further enhancement to support the transition towards the desired WSS in China. Finally, some general insights are provided for policy innovations in other political economies.
For decades, the Chinese government has been searching for solutions to cope with the increasing imbalance between the supply and demand of water in the Yellow River Basin. This paper aims at a better understanding of the development of the water allocation regime in the Yellow River Basin between 1950 and 2009, introducing a fresh perspective based on the notion of "regime transition". Accordingly, we investigated 1) whether so-called "Windows of Opportunity for Transition (WOPTs)" emerged, triggering a transition, and whether WOPT(s) resulted in a stable transition towards the new regime; 2) how informal learning processes and epistemic communities have contributed to the regime change. We adapted Kingdon's "multiple stream model" and identified four WOPTs from the 1950s, analyzing the reconfiguration process of the regime after the onset of the transition. Our examples of two types of informal learning processes demonstrate their contribution to the creation of WOPTs and the reconfiguration of the regime. Furthermore, this study indicates, in a qualitative manner, how epistemic communities contribute to the knowledge base of the regime, and thus to its development. Finally, we have provided a general insight into the further development of the water allocation regime and highlighted potential avenues for further studies.
This chapter is an excerpt from a study commissioned by the European Parliament, which examines EU subsidies for agriculture, fisheries, transport, energy and regional development. Based on proven methodologies for the identification and assessment of environmentally harmful subsidies, the study assesses the sustainability level of the sectoral policies and makes recommendations for a reform that would contribute to the alignment of the EU budget towards a more sustainable growth. The following sections provide the main findings of one of the largest fields of expenditure within the EU budget, the structural and cohesion policy.
In the past few decades, geochemically scarce metals have
become increasingly relevant for emerging technologies in
domains such as energy supply and storage, information and
communication, lighting or transportation, which are regarded as
cornerstones in the transition towards a sustainable post-fossil
society. Accordingly, the supply risks of scarce metals and possible
interventions towards their more sustainable use have been
subject to an intense debate in recent studies. In this article, we
integrate proposed intervention options into a generic life cycle
framework, taking into account issues related to knowledge
provision and to the institutional setting. As a result, we obtain
a landscape of intervention fields that will have to be further
specified to more specific intervention profiles for scarce metals
or metals families. The envisioned profiles are expected to have
the potential to reduce action contingency and to contribute to
meeting the sustainability claims often associated with emerging
technol ogies.
Multinational mining companies operating in Latin America increasingly publish sustainability reports which outline their contributions to sustainable development. Companies argue that reports help communities better understand the importance of the benefits created by mining. However, we argue that sustainabilityreporting can only play a role in improving a company's performance and reputation if the quality of the reported data is good enough to answer community-raised contentious issues and if such are tackled through a stakeholder engagement process which includes "anti-mining" groups. The paper examines a miningconflict in Argentina's Bajo de la Alumbrera open pit mine. The assessment is based on a content analysis of Alumbrera's Sustainability Report (SR), primarily from 2009, complemented with insights from the 2010 and 2011 reports. The study reveals that environmental and economic indicators are the most contentious and least reported. The reports examined only briefly acknowledge these issues, and fail to detail the procedures followed to identify and engage stakeholders.
Increasing urbanisation and climate change belong to the greatest challenges of the 21st century. A high share of global greenhouse gas emissions are estimated to originate in urban areas (40 % to 78 % according to UN Habitat 2010). Therefore, low carbon city strategies and concepts implicate large greenhouse gas (GHG) mitigation potentials. At the same time, with high population and infrastructure densities as well as concentrated economic activities, cities are particularly vulnerable to the impacts of climate change and need to adapt. Scarce natural resources further constrain the leeway for long-term, sustainable urban development. The Low Carbon Future Cities (LCFC) project aims at tapping this three-dimensional challenge and will develop an integrated strategy / roadmap, balancing low carbon development, gains in resource efficiency and adaptation to climate change. The study focuses on two pilot regions - one in China (Wuxi) and one in Germany (Düsseldorf+) - and is conducted by a German-Chinese research team supported by the German Stiftung Mercator. The paper gives an overview of first outcomes of the analysis of the status quo and assessment of the most likely developments regarding GHG emissions, climate impacts and resource use in Wuxi. The project developed an emission inventory for Wuxi to identify key sectors for further analysis and low carbon scenarios. The future development of energy demand and related CO2 emissions in 2030 were simulated in the current policy scenario (CPS), using five different sub-models. Selected aspects of Wuxi's current material and water flows were analysed and modelled for energy transformation and the building sector. Current and future climate impacts and vulnerability were investigated. Recent climatic changes and resulting damages were analysed, expected changes in temperature and precipitation in the coming four decades were projected using ensembles of three General Circulation Models. Although Wuxi's government started a path to implement a low carbon plan, the first results show that more ambitious efforts are needed to overcome the challenges faced.
Dieser Beitrag stellt Ressourcenproduktivität als Kernstrategie vor. Schließlich kann sie nicht nur als Entschlackungskur fungieren, sondern auch als Innovationsmotor. Darüber hinaus wird ein Vorschlag zu einer internationalen Konvention für ein nachhaltiges Ressourcenmanagement gemacht, das vorhandene Verzerrungen reduzieren und zur Prävention von Ressourcenkonflikten beitragen soll. Erforderlich ist eine Sichtweise, bei der Material-, Energie-, Umwelt- und Technologieaspekte einerseits und internationale Entwicklungsaspekte andererseits integriert betrachtet werden. Schließlich geht es nicht um Rohstoffe als solche, sondern um ihre Funktion für menschliche Bedürfnisbefriedigung und Wohlstand. Nötig ist ein Paradigmenwechsel, in dem ein reines Angebotsdenken - welche Rohstoffmengen werden benötigt und wie können sie beschafft werden - zugunsten einer Systemperspektive überwunden wird.
Vor dem Hintergrund des Klimawandels und der Verknappung fossiler Ressourcen haben nachwachsende Rohstoffe in den letzten Jahren an Bedeutung gewonnen. Insbesondere die Bioenergie hat durch staatliche Fördermaßnahmen viel Aufmerksamkeit erfahren. Mit der Ausweitung der energetischen Nutzung von Biomasse sollen Beiträge zum Klimaschutz durch die Vermeidung von Treibhausgasen geleistet, die Versorgungssicherheit soll durch Ersatz der knapper werdenden fossilen Ressourcen erhöht und der ländliche Raum gestärkt werden. Die selben Argumente lassen sich auch für die stoffliche Nutzung von Biomasse heranziehen. Auch wenn diese etwas aus dem Blickfeld der energiebezogenen Diskussion geraten ist, kann hier in den nächsten Jahren ein erhebliches Marktwachstum erwartet werden. Biomasse als erneuerbare Ressource kann in Land- und Forstwirtschaft aber nur begrenzt bereitgestellt werden. Dies gilt umso mehr, als bestimmte Nachhaltigkeits-Anforderungen eingehalten werden müssen. Der zu erwartenden Nachfragesteigerung für nachwachsende Rohstoffe (Nawaro) steht damit eine limitierte Verfügbarkeit entgegen. Aus dieser leitet sich die Forderung nach einer möglichst effizienten Verwertung ab. In diesem Zusammenhang fällt immer häufiger der Begriff der Kaskadennutzung von Nawaro als möglicher Lösungsansatz. Dieses Konzept kann im Wesentlichen als eine Hintereinanderschaltung von (mehrfacher) stofflicher und energetischer Nutzung desselben Rohstoffs gesehen werden und schafft so eine Verbindung von Material- und Energiesektor. Das Prinzip der Kaskadennutzung ist damit ein Ansatz zur Steigerung der Rohstoffeffizienz von nachwachsenden Rohstoffen und zur Optimierung der Flächennutzung. Das Ziel des vorliegenden Berichts ist es, die Option "Kaskadennutzung" strategisch, differenziert und ganzheitlich zu beleuchten. Im Rahmen der Projektarbeit sind daher Anforderungen an eine nachhaltige Kaskadennutzung von Nawaro abgeleitet und Schlussfolgerungen zu deren Ausgestaltung gezogen worden, um die Potenziale von Biomasse hochwertig und erfolgreich zu nutzen.
Im Zentrum dieser Untersuchung steht die Aufbereitung der Erfahrungen mit den Elektrofahrzeugen in Einzelprojekten der Modellregionen Phase I hinsichtlich der energiebezogenen Parameter und der nach Fahrzeugsegmenten differenzierte Vergleich mit herkömmlichen Fahrzeugen. In der Literatur finden sich für die Klimabilanz von Elektrofahrzeugen unterschiedliche Bewertungsmethoden, deren Ergebnisse kurzfristig stark streuen und sich erst mittel- bis längerfristig perspektivisch annähern. In der vorliegenden Untersuchung werden drei Varianten zur Bilanzierung der klimarelevanten Emissionen gerechnet: a) Werden Elektrofahrzeuge mit Strom aus erneuerbaren Energien betrieben, ist ihre Klimabilanz deutlich besser als diejenige fossil betriebener Pkw. Wann, inwieweit und unter welchen Voraussetzungen (Herkunftsnachweis) eine direkte Zuordnung des Fahrstroms zu einer Stromerzeugung aus erneuerbaren Energien möglich ist, ist heute allerdings umstritten. b) Unter pragmatischen Gesichtspunkten bietet die Strommixmethode eine gute Orientierung für die klimabezogene Bewertung von Elektrofahrzeugen. Aufgrund der auf der Zeitachse planungsgemäß zunehmenden Anteile erneuerbarer Energien im Strommix führt dies für die Zeiten, in denen eine signifikante Durchdringung mit Elektrofahrzeugen zu erwarten ist, zu einer gegenüber heute deutlichen Verbesserung der spezifischen CO2-Emissionen und respektive Vorteilen gegenüber mit fossilen Kraftstoffen betriebenen Fahrzeugen. c) Legt man dem Kraftwerkseinsatz Merit Order als Regel des ökonomischen Betriebs zugrunde und betrachtet den Stromverbrauch von Elektrofahrzeugen als "zusätzlichen" Verbrauch gegenüber einem Zustand ohne Elektrofahrzeuge, stellt sich die Klimabilanz nicht so günstig dar.
The challenges of resource efficiency and appropriate strategies : a special issue in "SAPIENS"
(2011)
Natural resources are back on the agenda. After the rise of new economic powers such as China, India, and Brazil, global competition has perceptibly increased strategic concerns as regards high commodity prices and possible supply shortages. Germany, the EU, the United States, and many others have formulated raw material strategies that put concern over access and supply at center stage - but the environmental and the socio-political dimensions are widely neglected in these strategies. This paper underlines a new dimension of international relations and pleads for new approaches, called international resource politics, which can be used for ongoing debates concerning green economy and transition strategies.
Global trade is increasingly being challenged by observations of growing burden shifting, in particular of environmental problems. This paper presents the first worldwide calculations of shifted burden based on material flow indicators, in particular direct and indirect physical trade balances. This study covers the period between 1962 and 2005 and includes between 82 and 173 countries per year. The results show that indirect trade flow volumes have increased to around 41 billion tonnes in 2005. The traded resources with the highest share of associated indirect flows are iron, hard coal, copper, tin and increasingly palm oil. Regarding the burden balance between regions, Europe is the biggest shifter whereas Australia and Latin America are the largest takers of environmental burden due to resource extraction. To evaluate the findings from a global perspective, the results are analysed in terms of resource flow induced environmental pressure related to a country's land area in terms of total and per capita area. Resource endowment and population density seem to be more relevant in determining the physical trade balance, including indirect flows, than income level.
This paper focuses on market incentives by the introduction of a construction minerals tax as an example of a resource tax. Currently, various European countries levy taxes or duties on primary construction materials, but a harmonisation of the taxation is not planned. Provided the tax rate has a perceptible price effect, the taxation of a resource can foster a demand management or the reduction of the raw material consumption and the governance of side and secondary effects. A construction minerals tax can target the stimulation of demand for secondary raw materials and recycled products, and - because the reuse of construction and demolition waste has technical limits - a stronger emphasis on the conservation of buildings and infrastructures. This has positive effects on the environment and the innovation efforts and it helps to internalise externalities. Germany, used as a case study in this paper, does not raise any taxes on other raw materials than energy sources at the federal level. For this reason, potential impacts of the introduction of a construction minerals tax will be explored and the results of a simulation will be provided.
Northrhine-Westphalia (NRW) is the largest land of the Federal Republic of Germany. Until the 1970ies the Ruhr-area with a population of about 12 million people and a strong coal, steel and chemical industry had been plagued with severe pollution. In the 1970ies environmental protection had emerged on the international and national policy agendas. The federal and regional government launched massive legislative and economic public interventions for cleaning-up rivers, soils and air. As a result, a highly competitive eco-industry emerged. The article outlines main features of ecoindustries, the structural change of the Ruhr area and regional economic cluster policies in support of eco-industries in NRW. It draws conclusions for eco-industry policy developing from end-of-pipe towards integrated preventive approaches.
Concerns over climate change and the security of industrial feedstock supplies have been opening a growing market for biobased materials. This development, however, also presents a challenge to scientists, policy makers, and industry because the production of biobased materials requires land and is typically associated with adverse environmental effects. This article addresses the environmental impacts of biobased materials in a meta-analysis of 44 life cycle assessment (LCA) studies. The reviewed literature suggests that one metric ton (t) of biobased materials saves, relative to conventional materials, 55 ± 34 gigajoules of primary energy and 3 ± 1 t carbon dioxide equivalents of greenhouse gases. However, biobased materials may increase eutrophication by 5 ± 7 kilograms (kg) phosphate equivalents/t and stratospheric ozone depletion by 1.9 ± 1.8 kg nitrous oxide equivalents/t. Our findings are inconclusive with regard to acidification (savings of 2 ± 20 kg sulfur dioxide equivalents/t) and photochemical ozone formation (savings of 0.3 ± 2.4 kg ethene equivalents/t). The variability in the results of life cycle assessment studies highlights the difficulties in drawing general conclusions. Still, common to most biobased materials are impacts caused by the application of fertilizers and pesticides during industrial biomass cultivation. Additional land use impacts, such as the potential loss of biodiversity, soil carbon depletion, soil erosion, deforestation, as well as greenhouse gas emissions from indirect land use change are not quantified in this review. Clearly these impacts should be considered when evaluating the environmental performance of biobased materials.
This paper addresses future perspectives for the management of resources on an international level. Failures of international open markets result in significant material leakage. Here, taking the example of material used vehicles, we develop elements of an international metal covenant that should allow for a more sustainable management of global material flows in that area. Our proposal is based on two principles: any regulation should actively seek industry participation, taking advantage of business interest in supplying a sufficient quantity of materials while lowering materials costs; and it should also address public issues such as sustainability of recycling and waste. In this paper we first analyse contracts as a tool for bridging gaps in knowledge when multiple actors are involved. We then give empirical evidence for material leakage in the case of used vehicles from Germany, before outlining the elements of a proposed international metals covenant. Finally, we analyse potential impacts and discuss legal and institutional issues.
The exploitation of coltan in Central Africa can be considered a case of conflict minerals due to its nature. Many international organizations and bodies, national governments and private sector organizations seek to address this conflict, in particular via transparency, certification and accountability along the material supply chain. This paper analyses the international trade dimension of coltan and gives evidence on the dimension of illicit trade of coltan. The authors start from the hypothesis that illicit trade of coltan sooner or later will enter the market and will be reflected in the statistics. The paper is structured in the following manner: first, a short section gives a profile of coltan production and markets; second, an overview of the mining situation in the Democratic Republic of Congo (DRC) and related actors. The third section addresses mechanisms, actors and measurement issues involved in the international trade of coltan. The final part draws lessons for certification and conflict analysis and offers some guidance for future research.
The paper identifies two main possible gateways to trace illegal trade in coltan: the neighboring countries, especially Rwanda, and the importing countries for downstream production, in particular China. Our estimation is that the value of such illicit trade comes close to $ 27 million annually (2009), roughly one-fifth of the world market volume for tantalum production. With regard to any certification the paper concludes that this will become challenging for business and policy: (a) Central Africa currently is the largest supplier of coltan on the world market, many actors profit from the current situation and possess abilities to hide responsibility; (b) China will need to accept more responsibility, a first step would be the acceptance of the OECD guidelines on due diligence; (c) better regional governance in Central Africa comprises of resource taxation, a resource fund and fiscal coordination. An international task force may provide more robust data, however more research will also be needed.

Das Forschungsvorhaben startete im April 2008 vor Verabschiedung des Kabinettsberichts der Bundesregierung zur Deutschen Anpassungsstrategie an den Klimawandel (DAS). In der DAS wird die Bedeutung der Information über Erfordernisse zur Anpassung und der aktiven Einbindung aller gesellschaftlichen Gruppen in den weiteren Prozess der Strategieentwicklung betont. Das Forschungsvorhaben hat dazu Vorschläge für eine Einbeziehung gesellschaftlicher Gruppen über das Internet und zur Einbeziehung von stakeholdern über Dialog- und Kommunikationsprozesse gemacht. Diese Vorschläge basieren im Wesentlichen auf einer Interessenanalyse über Interviews mit Stakeholdern und der Wirtschaft zu deren Anforderungen und Erwartungen an die DAS. Daneben wurden internationale Beispiele zur Anpassung an den Klimawandel recherchiert und als "good practice" in einer Broschüre für die Öffentlichkeitsarbeit aufbereitet. Für die Internet-Plattform www.anpassung.net wurden in Form von Projektsteckbriefen konkrete Vorschläge zur interaktiven Ausgestaltung der Plattform entwickelt.Ziel des von Öko-Institut und Wuppertal Institut durchgeführten UFOPLAN-Vorhabens war es, für Deutschland zum Komplex Abfallvermeidung eine fundierte Datenbasis über bestehende Maßnahmen der öffentlichen Hand sowie über angewandte Instrumente auf kommunaler, Länder- und Bundesebene zu schaffen. Damit wurde zugleich eine Datenbasis für die Erstellung eines nationalen Abfallvermeidungsprogramms, welche die Mitgliedstaaten gemäß der novellierten Abfallrahmenrichtlinie bis 2013 erarbeiten müssen, geschaffen. Hierzu wurden die in Deutschland und im Ausland bestehenden Abfallvermeidungsmaßnahmen der öffentlichen Hand auf lokaler, regionaler, Landes- und Staatsebene tabellarisch dargestellt und entsprechend dem Ziel, der Ebene sowie einer qualitativen Bewertung ihrer Vermeidungswirkung, beschrieben, soweit Informationen hierfür vorliegen. Schließlich wurden neue staatliche Abfallvermeidungsmaßnahmen in der Literatur identifiziert und geeignete Benchmarks, soweit sie im Rahmen der Recherchen ermittelt wurden, beschrieben. Insgesamt wurden 296 Maßnahmen aus über 20 Ländern erfasst und erste Schlussfolgerungen für mögliche Schwerpunkte eines nationalen Abfallvermeidungsprogramms gezogen.

Development of scientific and technical foundations for a national waste prevention programme
(2010)
In a new waste hierarchy the amended EU Waste Framework Directive (WFD) (2008/98/EG) confirmed the prevention of waste as a priority measure to protect the environment with regard to the production and handling of waste. Amongst others the Member States are requested to promote waste prevention. According to article 29 par. 1 WFD the prevention measures have to be planned in terms of waste prevention programmes to be created by the Member States until December 12th 2013. These prevention programmes are to describe existing waste prevention measures and set waste prevention goals. The progress is to be monitored and assessed by targeting appropriate, specific qualitative or quantitative benchmarks for adopted waste prevention measures. The programmes may be included in waste management plans or other environmental programmes. By the objectives and measures of prevention programmes the environmental impacts associated with generation of waste shall be decoupled from economic growth.
Towards a resource policy : unleashing productivity dynamics and balancing international distortions
(2012)
The paper outlines guidelines and pillars of a resource policy. Two reasons favour the formulation of such policy: a demand to increase sluggish resource productivity growth as well as environmental damages occurring along material flows at an international scale. Thus, it is both the innovation and environmental perspective that legitimate policies. The paper surveys recent empirical trends. Referring to research on innovation and transition management, it develops guidelines for a resource policy, namely, market order, provision function, learning processes, market development, and orientation. It furthermore describes four instruments as potential pillars of a future policy mix: a tax on construction minerals, an ecologically differentiated VAT tax, and an international covenant for metals and an international convention for sustainable resource management. The paper finally reflects these guidelines and pillars against weaknesses and ongoing discussions of climate policy. It concludes that despite all uncertainties and complexities, a well-designed resource policy is on the verge of becoming essential for unleashing eco-innovation dynamics.
Managing solid waste is one of the biggest challenges in urban areas around the world. Technologically advanced economies generate vast amounts of organic waste materials, many of which are disposed to landfills. In the future, efficient use of carbon containing waste and all other waste materials has to be increased to reduce the need for virgin raw materials acquisition, including biomass, and reduce carbon being emitted to the atmosphere therefore mitigating climate change. At end-of-life, carbon-containing waste should not only be treated for energy recovery (e.g. via incineration) but technologies should be applied to recycle the carbon for use as material feedstocks. Thermochemical and biochemical conversion technologies offer the option to utilize organic waste for the production of chemical feedstock and subsequent polymers. The routes towards synthetic materials allow a more closed cycle of materials and can help to reduce dependence on either fossil or biobased raw materials. This chapter summarizes carbon-recycling routes available and investigates how in the long-term they could be applied to enhance waste management in both industrial countries as well as developing and emerging economies. We conclude with a case study looking at the system-wide global warming potential (GWP) and cumulative energy demand (CED) of producing high-density polyethylene (HDPE) from organic waste feedstock via gasification followed by Fischer–Tropsch synthesis (FTS). Results of the analysis indicate that the use of organic waste feedstock is beneficial if greenhouse gas (GHG) emissions associated with landfill diversion are considered.
Fossil independence and substantial reductions in CO2 emissions seem to be possible with 2nd generation biofuels. New technologies allow a full carbon-to-fuel conversion of non-edible plant parts such as straw or wood, and the cultivation of algae or salt-resistant plants uncouples bioenergy from food production. Nevertheless, impacts on biodiversity, global land and water use are widely unclear and their competitiveness with 1st generation biofuels and electric mobility is an open question. An interdisciplinary team of Empa, University of Zurich and the Wuppertal Institute of Climate, Environment and Energy evaluated the most sustainable production techniques and assessed their potential for our future mobility.
Urban mining

Consumption of natural resources should not exceed sustainable levels. The increasing use of biofuels and to some extent biomaterials, on top of rising food and feed demands, is causing countries to use a growing amount of global land, which may lead to land use conflicts and the expansion of cropland and intensive cultivation at the expense of natural ecosystems. Selective product certification cannot control the land use change triggered by growing overall biomass consumption. We propose a comprehensive approach to account for the global land use of countries for their domestic consumption, and assess this level with regard to globally acceptable levels of resource use, based on the concept of safe operating space. It is shown that the European Union currently uses one-third more cropland than globally available on a per capita basis and that with constant consumption levels it would exceed its fair share of acceptable resource use in 2030. As the use of global forests to meet renewable energy targets is becoming a concern, an approach to account for sustainable levels of timber flows is also proposed, based on the use of net annual increment, exemplified with preliminary data for Switzerland. Altogether, our approach would integrate the concept of sustainable consumption into national resource management plans; offering a conceptual basis and concrete reference values for informed policy making and urging countries to monitor and adjust their levels of resource consumption in a comprehensive way, respectful of the limits of sustainable supply.
As illustrated by the case studies of end-of-life vehicles and waste electric and electronic equipment, the approach of an extended producer responsibility is undermined by the exports of used and waste products. This fact causes severe deficits regarding circular flows, especially of critical raw materials such as platinum group metals. With regard to global recycling there seems to be a responsibility gap which leads somehow to open ends of waste flows and a loss or down-cycling of potential secondary resources. Existing product-orientated extended producer responsibility (EPR) approaches with mass-based recycling quotas do not create adequate incentives to supply waste materials containing precious metals to a high-quality recycling and should be amended by aspects of a material stewardship. The paper analyses incentive effects on EPR for the mentioned product groups and metals, resulting from existing regulations in Germany. It develops a proposal for an international covenant on metal recycling as a policy instrument for a governance-oriented framework to initiate systemic innovations along the complete value chain taking into account product group- and resource group-specific aspects on different spatial levels. It aims at the effective implementation of a central idea of EPR, the transition of a waste regime still focusing on safe disposal towards a sustainable management of resources for the complete lifecycle of products.
This contribution presents the state of the art of economy-wide material flow accounting. Starting from a brief recollection of the intellectual and policy history of this approach, we outline system definition, key methodological assumptions, and derived indicators. The next section makes an effort to establish data reliability and uncertainty for a number of existing multinational (European and global) material flow accounting (MFA) data compilations and discusses sources of inconsistencies and variations for some indicators and trends. The results show that the methodology has reached a certain maturity: Coefficients of variation between databases lie in the range of 10% to 20%, and correlations between databases across countries amount to an average R2 of 0.95. After discussing some of the research frontiers for further methodological development, we conclude that the material flow accounting framework and the data generated have reached a maturity that warrants material flow indicators to complement traditional economic and demographic information in providing a sound basis for discussing national and international policies for sustainable resource use.
During the last century, the consumption of materials for human needs increased by several orders of magnitude, even for non-renewable materials such as metals. Some data on annual consumption (input) and recycling/waste (output) can often be found in the federal statistics, but a clear picture of the main flows is missing. A dynamic material flow model is developed for the example of copper in Switzerland in order to simulate the relevant copper flows and stocks over the last 150 years. The model is calibrated using data from statistical and published sources as well as from interviews and measurements. A simulation of the current state (2000) is compared with data from other studies. The results show that Swiss consumption and losses are both high, at a level of about 8 and 2 kg/(cap year), respectively, or about three times higher than the world average. The model gives an understanding of the flows and stocks and their interdependencies as a function of time. This is crucial for materials whose consumption dynamics are characterised by long lifetimes and hence for relating the current output to the input of the whole past. The model allows a comprehensive discussion of possible measures to reduce resource use and losses to the environment. While increasing the recycling reduces losses to landfill, only copper substitution can reduce the different losses to the environment, although with a time delay of the order of a lifetime.
Die globalen Rohstoffmärkte weisen Defizite mit erheblichem Konfliktpotenzial auf. Die Bewältigung von Umweltbelastungen, Ressourcenkonflikten, illegalem Handel und Preissprüngen bedürfen einer institutionellen Ordnung. Eine global nachhaltige Ressourcennutzung erfordert verbesserte und neue Governance-Mechanismen, die sowohl privatwirtschaftliche als auch staatliche Akteure einbeziehen. Mögliche neue Governance-Ansätze wären die Gründung einer International Resource Management Agency, die Schaffung eines internationalen Metall-Covenants und eines Abkommens zum nachhaltigen Ressourcenmanagement.
This paper analyses drivers for resource use and material productivity acrosscountries. This is not only relevant in light of soaring raw material prices but also because EU policies, such as the "Thematic Strategy on the Sustainable Use of Natural Resources" (COM [2005] 670), the EU Raw Materials Initiative (COM [2008] 699) and various similar policies internationally, seek to better manage materials along their life-cycle and across economies. In order to better understand the system dynamics of material use, our paper applies methodologies of material flow analysis and regression analysis to identify the major drivers for resource use and decoupling from GDP. Drivers are understood as those factors that exert influence on human activities to use resources. A panel data set is taken for the European Union for the years 1980–2000 (EU-15) and 1992–2000 (EU-25). The main drivers of resource use were found to be energy efficiency, new dwellings and roads construction activities. Shortcomings of the methodology are also discussed.

This article addresses informational barriers to energy efficiency. It is a widely acknowledged result that an energy efficiency gap exists implying that the level of energy efficiency is at an inefficiently low level. Several barriers to energy efficiency create this gap and the presence of asymmetric information is likely to be one such barrier. The article finds that problems of moral hazard and adverse selection indeed can help explain the seemingly low levels of energy efficiency. The theory reveals two implications to policies on energy efficiency. First, the development of measures to enable contractual parties to base remuneration on energy performance must be enhanced, and second, the information on technologies and the education of consumers and installers on energy efficiency must be increased. Finally, it is found that the preferred EU policy instrument on energy efficiency, so far, seems to be the use of minimum requirements. Less used in EU legislation is the use of measuring and verification as well as the use of certifications. Therefore, it is concluded that the EU should consider an increased use of these instruments.
Renania del Norte-Westfalia (RNW) es el mayor estado federal (land) de la República Federal de Alemania. Hasta la década de 1970, la región del Rin-Ruhr, con una población de unos 12 millones de habitantes y una potente industria química, del carbón y del acero, se vio afectada por graves problemas de contaminación. En los años setenta, la protección medioambiental apareció en las agendas políticas nacionales e internacionales. Los gobiernos federales y el estatal lanzaron múltiples intervenciones legislativas y económicas para limpiar ríos, suelos y aire. Como resultado, surgió una ecoindustria muy competitiva. En este artículo, se resumen las características de las ecoindustrias y se describe el cambio estructural de la región del Ruhr. Asimismo, centrándose en el mesonivel y empleando los ejemplos de la gestión energética y la gestión municipal de residuos, se destacan los puntos fuertes y los puntos débiles de las políticas económicas regionales de clusters que apoyan las ecoindustrias en RNW.
Overviewing the European carbon (C), greenhouse gas (GHG), and non-GHG fluxes, gross primary productivity (GPP) is about 9.3 Pg yr-1, and fossil fuel imports are 1.6 Pg yr-1. GPP is about 1.25% of solar radiation, containing about 360 × 1018 J energy - five times the energy content of annual fossil fuel use. Net primary production (NPP) is 50%, terrestrial net biome productivity, NBP, 3%, and the net GHG balance, NGB, 0.3% of GPP. Human harvest uses 20% of NPP or 10% of GPP, or alternatively 1‰ of solar radiation after accounting for the inherent cost of agriculture and forestry, for production of pesticides and fertilizer, the return of organic fertilizer, and for the C equivalent cost of GHG emissions. C equivalents are defined on a global warming potential with a 100-year time horizon. The equivalent of about 2.4% of the mineral fertilizer input is emitted as N2O. Agricultural emissions to the atmosphere are about 40% of total methane, 60% of total NO-N, 70% of total N2O-N, and 95% of total NH3-N emissions of Europe. European soils are a net C sink (114 Tg yr−1), but considering the emissions of GHGs, soils are a source of about 26 Tg CO2 C-equivalent yr-1. Forest, grassland and sediment C sinks are offset by GHG emissions from croplands, peatlands and inland waters. Non-GHGs (NH3, NOx) interact significantly with the GHG and the C cycle through ammonium nitrate aerosols and dry deposition. Wet deposition of nitrogen (N) supports about 50% of forest timber growth. Land use change is regionally important. The absolute flux values total about 50 Tg C yr-1. Nevertheless, for the European trace-gas balance, land-use intensity is more important than land-use change. This study shows that emissions of GHGs and non-GHGs significantly distort the C cycle and eliminate apparent C sinks.
This paper undertakes a step to explaining the international economics of resource productivity. It argues that natural resources are back on the agenda for four reasons: the demand on world markets continues to increase, the environmental constraints to using resources are relevant throughout their whole life cycle, the access to critical metals could become a barrier to the low carbon economy, and uneven patterns of use will probably become a source of resource conflicts. Thus, the issue is also of relevance for the transition to a low carbon economy. "Material Flow Analysis" is introduced as a tool to measure the use of natural resources within economies and internationally; such measurement methodology now is being harmonized under OECD auspices. For these reasons, the paper argues that resource productivity - that is the efficiency of using natural resources to produce goods and services in the economy - will become one of the key determinants of economic success and human well-being. An empirical chapter gives evidence on time series of resource productivity increases across a number of economies. Introducing the notion of "material flow innovation", the paper also discusses the innovation dynamics and issues of competitiveness. However, as the paper concludes, market barriers make a case for effective resource policies that should provide incentives for knowledge generation and get the prices right.
The papers for this special issue were originally contributed to the 2nd International Wuppertal Colloquium on "Sustainable Growth, Resource Productivity and Sustainable Industrial Policy - Recent Findings, new Approaches for Strategies and Policies" that was held from 10 to 12 September 2009 in Wuppertal, Germany. The intensive discussion during the Colloqium and the subsequent rigorous review process have helped to facilitate this process - we wish to thank all participants and contributers, as well as Sevan Hambarsoomian and Deniz Erdem for administrative support.
The physical dimension of international trade. Part 1: Direct global flows between 1962 and 2005
(2010)
The physical dimension of international trade is attaining increased importance. This article describes a method to calculate complete physical trade flows for all countries which report their trade to the UN. The method is based on the UN Comtrade database and it was used to calculate world-wide physical trade flows for all reporting countries in nine selected years between 1962 and 2005. The results show increasing global trade with global direct material trade flows reaching about 10 billion tonnes in 2005, corresponding to a physical trade volume of about 20 billion tonnes (adding both total imports and total exports). The share from European countries is declining, mainly in favour of Asian countries. The dominant traded commodity in physical units was fossil fuels, mainly oil. Physical trade balances were used to identify the dominant resource suppliers and demanders. Australia was the principal resource supplier over the period with a diverse material export structure. It was followed by mainly oil-exporting countries with varying volumes. As regards to regions, Latin America, south-east Asian islands and central Asia were big resource exporters, mostly with increasing absolute amounts of net exports. The largest net importers were Japan, the United States and single European countries. Emerging countries like the "Asian Tigers" with major industrial productive sectors are growing net importers, some of them to an even higher degree than European countries. Altogether, with the major exception of Australia and Canada, industrialized countries are net importers and developing countries and transition countries are net exporters, but there are important differences within these groups.
Comparative analysis of environmental impacts of maize-biogas and photovoltaics on a land use basis
(2010)
This study aims to stimulate the discussion on how to optimize a sustainable energy mix from an environmental perspective and how to apply existing renewable energy sources in the most efficient way. Ground-mounted photovoltaics (PV) and the maize-biogas-electricity route are compared with regard to their potential to mitigate environmental pressure, assuming that a given agricultural area is available for energy production. Existing life cycle assessment (LCA) studies are taken as abasis to analyse environmental impacts of those technologies in relation to conventional technology for power and heat generation. The life-cycle-wide mitigation potential per area used is calculated for the impact categories non-renewable energy input, green house gas (GHG) emissions, acidification and eutrophication. The environmental performance of each system depends on the scenario that is assumed for end energy use (electricity and heat supply have been contemplated). In all scenarios under consideration, PV turns out to be superior to biogas in almost all studied impact categories. Even when maize is used for electricity production in connection with very efficient heat usage, and reduced PV performance is assumed to account for intermittence, PV can still mitigate about four times the amount of green house gas emissions and non-renewable energy input compared to maize-biogas. Soil erosion, which can be entirely avoided with PV, exceeds soil renewal rates roughly 20-fold on maize fields. Regarding the overall Eco-indicator 99 (H) score under most favourable assumptions for the maize–biogas route, PV has still a more than 100% higher potential to mitigate environmental burden. At present, the key advantages of biogas are its price and its availability without intermittence. In the long run, and with respect to more efficient land use, biogas might preferably be produced from organic waste or manure, whereas PV should be integrated into buildings and infrastructures.
Economic performance of a country is generally being measured through GDP (Gross Domestic Product), a variable that has also become the de facto universal metric for "standards of living". However, GDP does not properly account for social and environmental costs and benefits. It is also difficult to achieve sustainable decision-making aiming at sustainable progress and well-being if welfare is being considered from a purely financial point of view. The study highlights the benefits and some of the shortcomings of GDP. It serves as a helpful and practicable instrument for monetary and fiscal policies. The real problem presumably is that GDP growth is too often confused with (sustainable) welfare growth in people's minds. While there certainly is a correlation between the two, this study shows that this is a highly conditional correlation, void of substantial causality for GDP levels observable in the European Union. In order to be able to assess people's well-being and general sustainable development in the sense of sustainability, an alternative instrument going beyond GDP is necessary. Using so called SWOT analyses, several alternative progress indicators have been assessed in the context of this study. On the one hand it was analysed how far ecological and social factors can be integrated in the GDP measurements. Thereby difficulties arose then trying to monetise these factors. As a further possibility indicators were analysed which are to replace GDP as a whole. The category supplementing GDP seems to be the most realistic and acceptable option for going beyond GDP. Within this approach, GDP is being complemented with additional environmental and/or social information. In order to make this kind of solution feasible the study claims the establishment of an overarching and transparent indicator system for improving economic decision-making in support of sustainable development.
Life Cycle Assessment (LCA) has matured over the past decades and become part of the broader field of sustainability assessment. To strengthen LCA as a tool and eventually increase its usefulness for sustainability decision-making, it is argued that there is a need to expand the ISO LCA framework by integration and connection with other concepts and methods. This paper explores the potential options for deepening and broadening the LCA methodologies beyond the current ISO framework for improved sustainability analysis. By investigating several environmental, economic and social assessment methods, the paper suggests some options for incorporating (parts of) other methods or combining with other methods for broadening and deepening the LCA.
This paper presents the strategy for a large EU-funded Integrated Project: EXIOPOL ("A New Environmental Accounting Framework Using Externality Data and Input-Output Tools for Policy Analysis"), with special attention for its part in environmentally extended (EE) input-output (IO) analysis. The project has three principal objectives: (a) to synthesize and further develop estimates of the external costs of key environmental impacts for Europe; (b) to develop an EE IO framework for the EU-27 in aglobal context, including as many of these estimates as possible, to allow for the estimation of environmental impacts (expressed as LCA themes, material requirement indicators, ecological footprints or external costs) of the activities of different economic sectors, final consumption activities and resource consumption; (c) to apply the results of the work to external costs and EE I-O for illustrative policy questions.
This paper reviews the current EU policy framework in view of its impact on hydrogen and fuel cell development. It screens EU energy policies, EU regulatory policies and EU spending policies. Key questions addressed are as follows: to what extent is the current policy framework conducive to hydrogen and fuel cell development? What barriers and inconsistencies can be identified? How can policies potentially promote hydrogen and fuel cells in Europe, taking into account the complex evolution of such a potentially disruptive technology? How should the EU policy framework be reformed in view of a strengthened and more coherent approach towards full deployment, taking into account recent technology-support activities? This paper concludes that the current EU policy framework does not hinder hydrogen development. Yet it does not constitute a strong push factor either. EU energy policies have the strongest impact on hydrogen and fuel cell development even though their potential is still underexploited. Regulatory policies have a weak but positive impact on hydrogen. EU spending policies show some inconsistencies. However, the large-scale market development of hydrogen and fuel cells will require a new policy approach which comprises technology-specific support as well as a supportive policy framework with a special regional dimension.
The paper aims to shed light on the methodological challenges of GHG monitoring at local level and to give an overview on current practices. Questions addressed are as follows: How do the methodologies which underlie different GHG inventory tools differ? What are the critical variables explaining differences between inventories? Can different GHG inventory tools be compatible - and/or interoperable - and under which conditions? The first section discusses methodological challenges related to the formation of local GHG inventories. Rather than giving a comprehensive overview on methodological problems, this section mainly highlights some of the central methodological challenges posed by local GHG inventories. This overview identifies critical variables and clarifies concepts that are necessary for the understanding of the subsequent analysis. In section two, some of the most advanced GHG inventory tools are analysed and the most important differences between these tools are highlighted. The paper concludes that the methodologies are not consistent. Local GHG inventories can thus hardly be compared. The paper gives research and policy recommendations towards greater comparability and sketches the requirements of an international protocol on urban GHG inventories.

The study "A Green New Deal for Europe" consists of two basic elements: Firstly it aims to cope with the economic crisis through intensive measures in order to systematically stimulate the eco-industries, to create jobs and to boost economic recovery. Secondly it aims at establishing the foundation for a green modernisation of the European economy. The study examines existing EU strategies policies and programs concerning their suitability to implement the Green New Deal. It proposes exemplary measures in the field of energy, mobility and resource use. The study has been compiled by the Wuppertal Institute on behalf of the Greens/European Free Alliance (EFA) Group in the European Parliament.
The global land area required to meet the German consumption of agricultural products for food and non-food use was quantified, and the related greenhouse gas (GHG) emissions, particularly those induced by land-use changes in tropical countries, were estimated. Two comprehensive business-as-usual scenarios describe the development corridor of biomass for non-food use in terms of energetic and non-energetic purposes. In terms of land use, Germany was already a net importer of agricultural land in 2004, and the net additional land required by 2030 is estimated to comprise 2.5–3.4 Mha. This is mainly due to biofuel demand driven by current policy targets. Meeting the required biodiesel import demand would result in an additional GWP of 23–37 Tg of CO2 equivalents through direct and indirect land-use changes. Alternative scenario elements outline the potential options for reducing Germany's land requirement, which reflect future global per capita availability.
Globale Rohstoffpolitik ist Umwelt-, Entwicklungs-, Sicherheits-, Innovations- und Wirtschaftspolitik in einem. Der Band analysiert aktuelle Herausforderungen globaler Rohstoffpolitik. Zugleich entwickelt er Perspektiven für ein globales Ressourcenmanagement auf der Grundlage verbesserter Transparenz und internationaler Verrechtlichung.
Sustainable management of natural resources is a crucial element for a sustainable development, but also a precondition for economic growth. The book analyses raw materials supply and resource use in a global context. The contributions present state-of-the art results and perspectives on the availability of resources. They discuss factors such as demand from emerging and other countries as well as critical shortage of some materials together with the resulting consequences for economies. It also gives new views and perspectives on the sustainable growth in ermerging economies and examines the possibilities and experiences concerning the decoupling of resource use from economic growth. Moreover, it offers cross-country comparisons with emphasis on emerging countries. A key focus is placed on China regarding its domestic energy, climate and resource policy but also its developing foreign policy in Africa.
On the one hand, biofuels may provide environmental and social benefits, for instance, when local communities in developing countries are supplied with power and process energy from oil producing plants, in particular when they are grown on land which is not suited for food production. On the other hand, the ongoing expansion of large scale energy farming for transport biofuels can lead to various environmental and social problems. Corn production for ethanol (additive to petrol) for instance resulted in nutrient pollution of the Mississippi basin and the Gulf of Mexico. The growing demand of transport biofuels in Europe can only be met by increasing imports. This contributes to the conversion of grasslands, savannahs and forests in the tropics, losses of biodiversity and additional green house gas emissions. Even if the use of biomass for other purposes, for instance, the combined production of electricity and heat usually provides a better greenhouse gas balance than transport biofuels, energy cropping remains problematic for various reasons. Whereas, when biomass is used for material purposes first, and the energy is recovered from the subsequent waste, a multiple dividend can be gained. The authors address a number of measures for improvement. They also recommend that in view of the complex circumstances of biofuel production and application, current policy mandates and targets for biofuels should be reconsidered. Biomass policies need to be integrated into a broader perspective of sustainable resource management.
Sustainable Resource Management is the result of longlasting exhaustive research by the Wuppertal Institute. Looking at material flows, industrial and societal metabolism and their implications for the economy, this new book provides radical perspectives on how the global economy should use natural resources in intelligent ways that maximise well-being without destroying lifesupporting ecosystems. It presents a vision of the future and the fundamental elements necessary for the sustainable management of the Earth's resources. It argues that the need to manage the use of our natural resources at a sustainable level can be shaped into a great opportunity for innovation and for new institutions to govern change.
A model of the use of the platinum group metals (PGMs) platinum, palladium, and rhodium in Europe has been developed and combined with a model of the environmental pressures related to PGM production. Compared to the base case presented in Part I of this pair of articles, potential changes in PGM production and use are quantified with regard to cumulative and yearly environmental impacts and PGM resource use, for the period 2005–2020. Reducing sulfur dioxide (SO2) emissions of PGM producer Norilsk Nickel could cut the cumulative SO2 emissions associated with the use of PGMs in Europe by 35%. Cleaner electricity generation in South Africa could reduce cumulative SO2 emissions by another 9%. Increasing the recycling rate of end-of-life catalytic converters to 70% in 2020 could save 15% of the cumulative primary PGM input into car catalysts and 10% of the SO2 emissions associated with PGM production. In 2020, PGM requirements and SO2 emissions would be, respectively, 40% and 22% lower than the base case. Substituting palladium for part of the platinum in diesel catalysts, coupled with a probable palladium price increase, could imply 15% more cumulative SO2 emissions if recycling rates do not increase. A future large-scale introduction of fuel cell vehicles would require technological improvements to significantly reduce the PGM content of the fuel cell stack. The basic design of such vehicles greatly influences the vehicle power, a key parameter in determining the total PGM requirement.

World primary copper production is expected to increase due to growing demand. Reflecting the geographical divergence of copper deposits and demanding industries, copper is produced by various production paths, differing in regional and technological aspects and related environmental pressures. For the mitigation of environmental pressures related to global material flows and a more sustainable resource management, policy makers, producers and buyers require information on regional resource efficiencies and effects of the key processes within the global production chain. This study quantifies material flows of refined copper production and environmental pressures along the pyro‐ and hydrometallurgical paths for Chile and Germany. Inventories for involved unit processes are distinguished by region and most commonly applied technologies, including electric power supply. Different production paths are compared by environmental pressure indicators (primary energy requirements, total material requirements, water consumption, GHG emissions, solid waste disposal, sulphur dioxide and arsenic emissions). Alternative options for improvement of technologies and supply patterns in Chile and Germany are compared.
The policy framework for the promotion of hydrogen and fuel cells in Europe : a critical assessment
(2008)
In this article, we analyze flows of the platinum group metals (PGMs) platinum, palladium, and rhodium and the environmental impacts associated with their supply in Europe. A model of the use of PGMs in Europe has been developed, and this is combined with a model of environmental pressures related to PGM production. Seven industrial sectors and product groups form the main users of PGMs in Europe, comprising the chemical, petroleum, and glass industries; jewelry, dentistry, electronic equipment, and car catalysts. Most relevant environmental impacts of secondary production in Europe and primary PGM production in South Africa, Russia, and Canada are taken into account, including emissions of sulphur dioxide and carbon dioxide and total material requirement. The article quantifies the PGM flows to, from, and within Europe in 2004. The automotive industry is the single largest user of primary PGMs, and catalytic converters represent the major PGM end use. The chemical and glass industries also require large amounts of PGM but rely mostly on secondary metals. The environmental impacts of primary production exceed those of secondary production by far. An analysis of the use of car catalytic converters shows that as a result of efforts to reduce air pollutant emissions in Europe, other negative environmental impacts, such as point-source pollution and mining waste, are occurring elsewhere - for example, at extraction and refining sites in Siberia and South Africa.
This article introduces elements of a global governance regime for sustainable resource management. It argues that such an approach is needed to combat the negative impacts arising from resource extraction and use as well as to overcome the co‐ordination problems of decentralized action. A first section summarizes main conflicts arising from limited access to natural resources and security of supply, environmental impacts and the performance of resource‐rich developing countries. A second section analyses existing initiatives for sustainable resource management such as resource funds, efforts to increase transparency, programmes in development co‐operation, standards and certification, material efficiency and resource productivity as well as efforts to limit the consumption of natural resources. Though these initiative have their merits, the article concludes that more systematic institutional mechanisms are needed. The third section introduces those institutional mechanisms: it describes the International Panel for Sustainable Resource Management (launched in November 2007), outlines elements of an international convention on sustainable resource management, develops the agenda for an international agency on the issue and discusses the interaction with existing international bodies such as the World Trade Organization. Written as a policy paper, the paper formulates proposals for various actors, from small‐scale miners to large‐scale global companies and governments. Its intention is to stimulate the debate and to broaden the horizon on the global dimension of using minerals.
The Wuppertal Institute for Climate, Environment and Energy and the UNEP/Wuppertal Institute Collaborating Centre on Sustainable Consumption and Production (CSCP) set out to analyse Japanese dematerialisation and resource efficiency strategies within the 3R scope and searched for options of enhancing resource effi ciency strategies, commissioned by the German Federal Environment Agency. A further task of the project was to initiate a policy dialogue including stakeholders, academia, politics and Japanese and European environmental experts. The following paper summarises findings from the analyses, the results of the policy dialogues (Experts Workshop, 6 June 2007 and International Conference, 6 November 2007) and draws conclusions for a potential Japanese-European cooperation on the resource efficiency issue.
Umweltbildung auf und durch Sportgroßveranstaltungen : Sportevents als Arena der Umweltbildung
(2007)
The use of materials and the generation of waste are linked to economic activities and in many projections these are assumed to be a constant ratio of the economic activities. This may be the case considering detailed economic activities and unchanged technology. However, the assumption of constant coefficients is questionable when linking material use and waste generation to aggregated economic activities. Therefore, in this paper, econometrics is used to test the assumption of constant waste coefficients empirically. The analyses show that an assumption of constant waste coefficients is not supported, generally, and amodel allowing for trendwise changing coefficients is developed and used for projections of waste and material flows in 25 European countries.
The material stocks in the anthroposphere are growing faster than ever due to urbanization and growing per capita use. Owing to the growing potential insecurity of raw material supply the evaluation of resources gains increasing attention. Despite growing utilization of anthropogenic deposits, ‘urban mining’ has not yet sufficiently been supported by specific exploration methods. An exploration method for anthropogenic deposits is proposed and described by application to the copper stocks of Switzerland. The method combines material flow analysis with a bottom‐up analysis of material stocks. The stock composition and temporal characteristics are analysed by surveys and literature analysis. The stock amounts to 269±31 kg capita -1 for the year 2000. The retrospective data are used as parameters to construct a dynamic stock model, which is calibrated by historical trade statistics. The potential for drafting scenarios is discussed. The stock situation in Switzerland is reviewed and compared with that of other regions.

This book considers corporate governance of sustainability from a co-evolutionary perspective. It explores the linkages between pro-active approaches at the corporate level, market-based incentives and environmental networks involving various actors. Relevant theory on corporate governance, competition, market failures and regulatory tools is also examined. The authors go on to present an assessment methodology suitable for empirical network analysis at the meso-level, and demonstrate its application using eight case studies. Based on these research results, Raimund Bleischwitz and his team draw important conclusions regarding policy analysis, sustainability assessment and the actors involved.
Globales Ressourcenmanagement : Konfliktpotenziale und Grundzüge eines Global Governance-Systems
(2007)
The enhanced use of biomass for the production of energy, fuels, and materials is one of the key strategies towards sustainable production and consumption. Various life cycle assessment (LCA) studies demonstrate the great potential of bio-based products to reduce both the consumption of non-renewable energy resources and greenhouse gas emissions. However, the production of biomass requires agricultural land and is often associated with adverse environmental effects such as eutrophication of surface and ground water. Decision making in favor of or against bio-based and conventional fossil product alternatives therefore often requires weighing of environmental impacts. In this article, we apply distance-to-target weighing methodology to aggregate LCA results obtained in four different environmental impact categories (i.e., non-renewable energy consumption, global warming potential, eutrophication potential, and acidification potential) to one environmental index. We include 45 bio- and fossil-based product pairs in our analysis, which we conduct for Germany. The resulting environmental indices for all product pairs analyzed range from -19.7 to +0.2 with negative values indicating overall environmental benefits of bio-based products. Except for three options of packaging materials made from wheat and cornstarch, all bio-based products (including energy, fuels, and materials) score better than their fossil counterparts. Comparing the median values for the three options of biomass utilization reveals that bio-energy (-1.2) and bio-materials (-1.0) offer significantly higher environmental benefits than bio-fuels (-0.3). The results of this study reflect, however, subjective value judgments due to the weighing methodology applied. Given the uncertainties and controversies associated not only with distance-to-target methodologies in particular but also with weighing approaches in general, the authors strongly recommend using weighing for decision finding only as a supplementary tool separately from standardized LCA methodology.

The paper reviews the current knowledge on the use of biomass for non-food purposes, critically discusses its environmental sustainability implications, and describes the needs for further research, thus enabling a more balanced policy approach. The life-cylce wide impacts of the use of biomass for energy and material purposes derived from either direct crop harvest or residuals indicate that biomass based substitutes have a different, not always superior environmental performance than comparable fossil based products. Cascading use, i.e. when biomass is used for material products first and the energy content is recovered from the end-of-life products, tends to provide a higher environmental benefit than primary use as fuel. Due to limited global land resources, non-food biomass may only substitute for a certain share of non-renewables. If the demand for non-food biomass, especially fuel crops and its derivates, continues to grow this will inevitably lead to an expansion of global arable land at the expense of natural ecosystems such as savannas and tropical rain forests. Whereas the current aspirations and incentives to increase the use of non-food biomass are intended to counteract climate change and environmental degradation, they are thus bound to a high risk of problem shifting and may even lead to a global deterioration of the environment. Although the "balanced approach" of the European Union's biomass strategy may be deemed a good principle, the concrete targets and implementation measures in the Union and countries like Germany should be revisited. Likewise, countries like Brazil and Indonesia may revisit their strategies to use their natural resources for export or domestic purposes. Further research is needed to optimize the use of biomass within and between regions.
Approaches to address unsustainable ways of societal development constantly proliferate, but total consumption of resources and aggregate environmental impacts continue rising. This could partially be explained by weak attempts to develop comprehensive sustainability strategies that address the entire life cycle of products and especially resource extraction and use phases. This paper seeks to explore to what extent these life cycle stages and associated impacts are taken into account when various actors employ life cycle thinking and how these concerns can be better attended to in policy-making, business strategies and lifestyle choices. To accomplish this, we evaluate the efforts of the main stakeholders in reaching sustainable consumption and sustainable resource management, and impediments to further progress, and study whether and how deficits in these phases coincide and can potentially contribute to more holistic practical realization of life cycle thinking. We demonstrate that new approaches are needed to be able to tackle the international dimension of production and consumption.

Das Wuppertal Paper von Rainer Lucas und Sandra Kolberg stellt sich der Frage, wie im Bereich der Messewirtschaft und insbesondere im Messebau die Materialeffizienz erhöht werden kann. Angesichts der kurzen Nutzungsdauer vieler Messestände und ihrer Ausstattungen konzentriert sich das Paper auf das Thema Produktdauerverlängerung. Die hiermit verbundenen Strategien werden zunächst auf ihre mögliche Anwendbarkeit in der Messewirtschaft überprüft. Danach wird es praktisch. Innovative Vorschläge und Konzepte für den Messestandbau, die Standausstattungen und neue Beratungs- und Informationsangebote werden vorgestellt. Hierbei wird deutlich: Bereits bei der Planung des Messestandes sollte auf die Recyclingfähigkeit der verwendeten Materialien geachtet werden. Das Produkt-Design bestimmt im Wesentlichen die Möglichkeiten einer Mehrfachnutzung und einer sinnvollen Nach- und Weiternutzung. Die Arbeit zeigt abschließend unter Beachtung der ökonomischen Rahmenbedingungen auf, welche Innovationspotenziale noch erschlossen werden können. Die vielen aufgeführten Beispiele belegen aber auch: in der Branche wird zunehmend erkannt, dass Materialeffizienz und Produktdauerverlängerung aufgrund der hohen Rohstoffpreise zu einem Wettbewerbsfaktor werden.
In a German case study, environmental input-output analyses (eIOA) combined with NAMEA-type tables were conducted for eleven selected environmental pressure variables. (NAMEA is an acronym for national accounts matrix including environmental accounts.) The analyses were conducted to derive the production-cycle-wide resource use and environmental impact potentials of final-demand product groups. The methodology permits identification and preliminary ranking of 10 product chains along which about two-thirds of German production-born environmental pressures arise. The most relevant product groups are construction work, food, motor vehicles, basic metals, and electricity. The ten product groups are characterized by both high resource requirements and high residual outputs (air emissions, wastes). The EU policy areas of integrated product policy and sustainable use of natural resources may address these product chains as a priority in order to identify and explore the possibility of reducing the environmental impacts from products throughout their life cycles and to decouple environmental impacts from resource use.
In der heutigen Spaß- und Konsumgesellschaft gewinnen Events als Marketingstrategie zunehmend an Bedeutung. Damit Unternehmen überhaupt noch Aufmerksamkeit erhalten, werden immer aufwändigere Events veranstaltet. Umweltaspekte spielen dabei eine eher untergeordnete Rolle. Doch das muss nicht so sein.
Policies for Sustainable Use and economy-wide Management of natural Resources (SUMR) throughout the production and consumption system are faced with environmental and socio-economic requirements and regulatory constraints. Based on empirical findings of ongoing trends of resource use, decoupling from economic growth, and transregional problem shifting, the paper outlines a potentially sustainable biophysical basis for production and consumption in the EU. It discusses the main challenges for the major resource groups, describing the specific and the common tasks with regard to biomass, fossil fuels, metals, non-metallic minerals. Adopting a medical metaphor, it suggests that policies for SUMR should follow a dual approach reflecting the long-term need for a main cure of the socio-industrial metabolism in form of a "conditioning" towards a more mature, resource efficient, and renewables based constitution on the one hand, and a fine tuning of selected material flows (e.g. for optimized recycling and control of hazardous compounds) on the other hand. Both strategies are deemed complementary and necessary to reduce environmental impacts and increase the utility of material use. Action required is exemplified with regard to the three pillars of SUMR, i.e. improved orientation, information and incentives.
The book contains the proceedings of INFER annual conference 2004, organized at the Wuppertal Institute in Germany. Within the area of environmental economics, methodological issues now seem at stake. This is because recent methods and fields of economics, like institutional economics, competition (industrial) economics, and cognitive economics, should be applied and become more established within environmental economics. The different papers address this challenge via different case studies in areas such as agriculture, biodiversity, eco-taxes, subsidies, wind energy, environmental corruption, governance, contracts, international trade, human behavior, and many others.
Objective of this study is to support the development of a Thematic Strategy for Sustainable Use and Management of Resources through the provision of background information, in particular "an estimate of materials and waste streams in the Community, including imports and exports" (Article 8 a 6th EAP) using the method of material flow accounting. It further presents first ideas on how the resource use pattern of the EU can be assessed with regards to priority setting for possible policy measures.
By referring to the concept of Industrial Metabolism, resources are defined in a broad sense, embracing the source and sink function of the natural environment, i.e. the provision of raw materials and land, and the absorption of residual materials (waste and emissions). Environmental impacts are associated not only with the extraction, harvesting and catching of raw materials but also with the subsequent production, use and disposal of products and goods. It is the total of environmental impacts associated with the entire life cycle of raw materials which has to be considered.
Three generic "management rules" for the sustainable use and management of renewable and non-renewable natural resources are presented and discussed which have been formulated by several political institutions based on scientific literature:
1. The use of renewable resources should not exceed their renewal and/or regeneration rates.
2. The use of non-renewable resources should not exceed the rate at which substitutes are developed (should be limited to levels at which they can either be replaced by physically or functionally equivalent renewable resources or at which consumption can be offset by increasing the productivity of renewable or non-renewable resources).
3. Outputs of substances to the environment (pollution) should not exceed the assimilative capacity of environmental media ("absorption capacities").
Die Erstellung von Gemeinschaftsgütern gilt als Problemfall für Märkte und ökonomisch handelnde Individuen. Das vorliegende Buch entwickelt einen neuen Ansatz, in dem Individuen und Unternehmen eine stärkere Rolle einnehmen. Anlass zur Markteuphorie ist jedoch nicht gegeben. Vielmehr ist es Aufgabe der Wirtschaftspolitik, solche Institutionen hervorzubringen, die das Handeln der Akteure auf direkte und indirekte Weise steuern. Dies wird im vorliegenden Buch als wissensbasierter Ansatz bezeichnet. Als Anwendungsbeispiel wird die Kreislaufwirtschaft analysiert. Ein Überblick, der die wesentlichen Thesen und Begründungsstränge enthält, führt in das Buch ein. Im folgenden Teil wird der wissensbasierte Ansatz modellhaft dargelegt. Erörtert werden die Bausteine Lernen, Kognition, Rationalität, deliberative Institutionenentwicklung und Wissen schaffender Wettbewerb. Für die Erstellung von Gemeinschaftsgütern wird ein Eigeninteresse abgeleitet, wenn der technologische und institutionelle Wandel entsprechende Signale generieren. Da beide Größen dem Einfluss von Individuen und Unternehmen unterliegen, entstehen Wechselwirkungen. Die folgenden Kapitel untersuchen den technologischen und institutionellen Wandel im Hinblick auf Potenziale zur Erstellung von Gemeinschaftsgütern. Dabei werden insbesondere neuere Unternehmenstheorien erörtert. Abgeleitet wird eine stufenförmige Grenzkostenfunktion für Institutionen und Organisationen. Ausführlich diskutiert das Buch Implikationen für die Wirtschaftspolitik. Es begründet und operationalisiert die Formulierung offener Ziele. Wirtschaftspolitik wird als Reform und Design von Institutionen konzipiert. Zu diesem Zweck werden zwölf Prüfkriterien formuliert. Dieses Konzept wird anschließend auf die Kreislaufwirtschaftspolitik übertragen. Defizite des Kreislaufwirtschaftsgesetzes (KrW-/AbfG) werden herausgearbeitet. Als Reformen präsentiert das Buch neue Ziele, Wissen generierende Institutionen und ökonomische Anreize. Insgesamt ist das Buch als theorieorientierte Analyse praktischer Probleme geschrieben. Es folgt Ansätzen der Neuen Institutionenökonomik und der evolutorischen Ökonomik. Diese Ansätze werden auf die Analyse der Erstellung von Gemeinschaftsgütern und die Erarbeitung von Lösungsoptionen angewendet.
Die gesellschaftlichen Rahmenbedingungen für eine ökologische Wende der EU-Regionalpolitik sind scheinbar ungünstig. Dem Vorsorgeprinzip der Umweltpolitik liegt die Annahme zugrunde, dass man auf bestimmte Tatsachen reagieren muss, weil sonst Schäden entstehen. Nach dem Soziologen Niklas Luhmann entspricht dies jedoch einer allzu einfachen Alltagsvorstellung. Der Ökonom Hans-Jochen Luhmann diagnostiziert hinsichtlich der Wahrnehmung von ökologisch relevanten Informationen eine regelrechte "Blindheit der Gesellschaft". Blockaden bei der Umsetzung von Umweltpolitik scheinen diese Befunde zu bestätigen. Der Planungswissenschaftler Arthur Benz meint in diesem Kontext, dass man bei der Durchsetzung von Planungskontrolle eben nicht mit dem freiwilligen Lernen der Akteure rechnen dürfe. Wie lässt sich unter diesen Bedingungen eine ökologische Wende der Europäischen Regionalpolitik umsetzen? Ist der Planungspessimismus, der sich in Deutschland nach einem Planungsoptimismus der 1970er Jahre durchgesetzt hat, gerechtfertigt? Welchen Wert können zielorientierte Instrumente wie etwa Indikatoren für die Umweltplanung in der Regionalpolitik noch haben? Vor dem Hintergrund gesellschaftlicher Differenzierung beleuchtet der Umweltwissenschaftler Philipp Schepelmann die Probleme, die bei der Anwendung von Umweltindikatoren in der regionalen Wirtschaftsförderung auftauchen. Für seine empirische Untersuchung im Ziel-2 Gebiet der EU-Strukturfonds in Nordrhein-Westfalen entwickelt er in Anlehnung an die soziologische Systemtheorie das Konzept der Resonanz. Resonanz bezeichnet die aktive Reaktion von sozialen Systemen auf Umweltprobleme als Voraussetzung für eine zielorientierte Umweltpolitik. Die Resonanz von Policy-Netzwerken gegenüber Umweltindikatoren kann nachgewiesen und verglichen werden. Am Beispiel der umweltpolitischen Indikatoren des Lissabon-Prozesses der Europäischen Union wird die regionale Resonanz von Indikatoren in verschiedenen Policy-Netzwerken untersucht. Das Ergebnis der Resonanzanalyse ist aus planerischer Sicht überraschend positiv: Es gibt nicht nur Blindheit und Untätigkeit gegenüber ökologischen Herausforderungen; differenzierte Policy-Netzwerke leiten in NRW erfolgreich eine ökologische Wende der EU-Regionalpolitik ein.
In this brochure, WISIONS focuses on the significance of innovative strategies in the field of sustainable tourism. WISIONS presents projects from Tanzania, Germany, Ecuador, Switzerland and Ghana that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for the selection of the projects was energy and resource efficiency, but social aspects such as the inclusion of local population were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Der vorliegende Artikel vergleicht die Nutzung nachwachsender Rohstoffe zur Erzeugung von Energie (Wärme und Elektrizität), Kraftstoffen und Gebrauchsprodukten anhand von vier ausgewählten Umweltbelastungskategorien. Dazu wurden Ökobilanzdaten aus 11 verschiedenen Publikationen für insgesamt 45 Produktpaare auf Basis nachwachsender und fossiler Rohstoffe analysiert und bezogen auf Einwohneräquivalente pro Hektar landwirtschaftliche Fläche miteinander verglichen. Die Ergebnisse zeigen im Allgemeinen Vorteile für die nachwachsenden Produktalternativen in den Kategorien Nichterneuerbarer Energieverbrauch und Treibhauspotenzial, während Produkte aus fossilen Ausgangsstoffen beim Eutrophierungspotenzial günstiger abschneiden und sich in der Kategorie Versauerungspotenzial uneinheitliche Resultate ergeben. Durch die Nutzung nachwachsender Rohstoffe zur Erzeugung von Gebrauchsgütern und Energie lassen sich durch Substitution der fossilen Produktalternativen größere ökologische Entlastungen realisieren als durch die Herstellung von Biokraftstoffen, die als Vollsubstitute für Diesel eingesetzt werden. Wesentliche Nachteile der Biomassenutzung sind mit dem Pflanzenanbau im Rahmen der konventionellen Landwirtschaft verbunden. Durch andere Bewirtschaftungsformen (z. B. Extensivierung) und eine besser an die jeweiligen Verwendungszwecke angepasste Auswahl bzw. Verarbeitung der nachwachsenden Rohstoffe könnten die Umweltbelastungen durch Energie, Kraftstoffe und Gebrauchsprodukte aus nachwachsenden Rohstoffen deutlich verringert werden.
Resource flows constitute the materials basis of the economy. At the same time, they carry and induce an environmental burden associated with resource extraction and the subsequent material flows and stocks, which finally end up as waste and emissions. A reduction of this material throughput and the related impacts would require a reduction of resource inputs. And breaking the link between resource consumption and economicgrowth would require an increase in resource productivity. Material flow analysis (MFA) can be used to quantify resource flows and indicate resource productivity. In this article, we study the available empirical evidence on the actual (de-)linkage of material resource use and economic growth. We compare resource use with respect to total material requirement (TMR) and direct material input (DMI) for 11 and 26 countries, respectively, and the European Union (EU-15). The dynamics of TMR, as well as of the main components are analysed in relation to economic growth in order to show whether there is a decoupling (relative or absolute) from GDP and a change of the metabolic structure in the course of economicdevelopment. DMI/cap so far only decoupled from GDP/cap in relative terms; that is, in most countries, it reached a rather constant level but - with the exception of Czech Republic - showed no absolute decline yet. TMR/cap was reduced in two high-income countries and one low-income country due to political influence. Changes in TMR were more influenced by hidden flows (HF) than by DMI. We analyse the dynamics of the structure and composition of TMR in the course of economic development. In general, the economic development of industrial countries was accompanied by a shift from domestic to foreign resource extraction. Different relations can be discovered for the share of biomass, fossil fuel resources, construction resources and metals and industrial minerals.
Die "Ökonomie der Aufmerksamkeit" hat zur Herausbildung spezifischer Märkte für Kommunikations-, Media- und Marketingdienstleistungen geführt. Ein dynamisch wachsender Markt ist der Markt für Live-Kommunikation, der in dieser Arbeit vertiefend untersucht wird. Hierbei werden drei Fragen diskutiert:
1. Was sind die treibenden Faktoren und Trends der Live-Kommunikation?
2. Nach welchen Maßstäben werden Events, insbesondere im Bereich der Unternehmenskommunikation, beauftragt?
3. Welche Chancen bestehen in diesem Markt, Events für Nachhaltigkeit als Marktsegment zu etablieren und zu stärken? Bei der Beantwortung dieser Fragen werden aktuelle Trendstudien ausgewertet, aber auch auf Untersuchungen und Fallstudien zurückgegriffen, die im Rahmen des Projektes "Eventkultur und Nachhaltigkeit" durchgeführt wurden.
Die Autoren kommen zu dem Ergebnis, dass die Markt- und Trendstudien eine wichtige Orientierungsfunktion für die Eventwirtschaft haben. Aus der Perspektive eines kulturökonomischen Ansatzes wird kritisiert, dass diese Orientierungsfunktion auf Marken und Marketingtechniken beschränkt ist und der Einfluss der gesellschaftlichen Wertbildung auf die Marketingpraxis ausgeblendet bleibt. Nachhaltige Ziele und Inhalte werden mit den Mitteln des Event-Marketings erst vereinzelt vermittelt. Aus diesen ersten Aktivitäten kann aber ein neuer Kommunikationsmarkt entstehen, wenn seitens der Nachhaltigkeitsakteure eine Verständigung über Kriterien und Anforderungen an dieses Marketinginstrument erfolgt sowie der Symbolebene in der Nachhaltigkeitskommunikation eine stärkere Beachtung geschenkt wird. Informationsbündelung und symbolisches Management sind wichtige Ansatzpunkte, um in der Marketingpraxis von Unternehmen, öffentlichen Einrichtungen, Verbänden, NGOs und von Kommunikations- und Eventagenturen eine nachhaltige Eventkultur zu verankern.
Bridging the data gap
(2004)
This paper examines the connection between globalisation, with its growth in world trade links, and certain ecological effects especially concerning "North-South" relations. Although world trade in the mid-nineties was significantly uncoupled from growth trends in the world economy, so that since then it has increased nearly three times faster than the global GDP, certain indicators of energy use and CO2 emissions have not developed proportionately to world trade; globalisation evidently does not lead to a situation where pressures on the environment are increasing to the same extent worldwide. This de-linking may, however, result in the kind of shifts that we examine here with reference to the material trade flows of the European Union. It will be shown that, in the course of globalisation, the countries of the EU have increasingly shifted environmental burdens on to the countries of the South, especially in the form of ecological rucksacks of imported raw materials, while at the same time reducing the pressure on their own domestic environment by extracting fewer material resources. Furthermore, goods whose production places intensive pressure on the environment (industrial emissions into the atmosphere and water, heavy metal emissions, etc.) have been increasingly imported from newly industrializing or developing countries. The greater covering of material requirements from foreign resources has served not so much the EU's internal consumption as its own production of export goods; this shows that the EU has an increasing share in the resource requirement of other economies. The paper concludes that it is absolutely necessary to consider the international dimension in any strategy for more productive use of resources in industrial countries. In the long term, the EU's resource use should also be reduced in absolute terms. This will also be necessary in order to reduce the pressure on the environment due to imports and exports.
This book presents important new research on applied eco-efficiency concepts throughout Europe. The aim of eco-efficiency is to achieve market-based measures of environmental protection, in order to enhance the prospects for sustainable development and achieve positive economic and ecological benefits. The distinguished authors discuss a number of themes surrounding eco-efficiency including the necessary conditions for technological dissemination and ecological modernization, and the role of government in enabling businesses and society to participate actively in this process. In particular, they highlight the application of existing European-based policies concerning material flows and energy. The authors also investigate some new concepts of sustainable development and provide a useful introduction to material flows analysis. In further chapters they study the emerging regulatory policies for eco-efficiency, and examine the issues of sustainable business and consumption strategies.
This article proposes a policy framework for analysing corporate governance toward sustainable development. The aim is to set up a framework for analysing market evolution toward sustainability. In the first section, the paper briefly refers to recent theories about both market and government failures that express scepticism about the way that framework conditions for market actors are set. For this reason, multi-layered governance structures seem advantageous if new solutions are to be developed in policy areas concerned with long-term change and stepwise internalisation of externalities. The paper introduces the principle of regulated self-regulation. With regard to corporate actors| interests, it presents recent insights from theories about the knowledge-based firm, where the creation of new knowledge is based on the absorption of societal views. The result is greater scope for the endogenous internalisation of externalities, which leads to a variety of new and different corporate strategies. Because governance has to set incentives for quite a diverse set of actors in their daily operations, the paper finally discusses innovation-inducing regulation. In both areas, regulated self-regulation and innovation-inducing regulation, corporate and political governance co-evolve. The paper concludes that these co-evolutionary mechanisms may assume some of the stabilising and orientating functions previously exercised by framing activities of the state. In such a view, the government's main function is to facilitate learning processes, thus departing from the state's function as known from welfare economics.
Wir wollen auf den Mars und sollten doch zuerst einmal auf der Erde landen. Hier warten ungelöste ökologische und ökonomische Probleme auf Lösungen. Stefan Bringezu lässt seine Leser gedanklich auf dem Planeten Erde neu landen. Dabei tauchen Fragen auf: Wie viel Verbrauch verträgt der Planet? Wo greift die Menschheit in natürliche Stoffströme ein, welche zusätzlichen Stoffströme setzt sie in Bewegung und welche Folgen haben diese? Menschliche Gesellschaft und Natur werden zu zwei komplexen Systemen, von denen das eine - die Gesellschaft - an das andere auf Gedeih und Verderb gekoppelt ist. Der Mensch ist in der Lage, seinen "Stoffwechsel" mit der Natur zu optimieren. Wie dieser gemessen werden kann und welche Lösungsansätze es bereits gibt, zeigt dieses Buch. Auch künftig wird es uns möglich sein, gut zu leben und zu wirtschaften, wenn wir den Verbrauch natürlicher Ressourcen nachhaltig gestalten.
Material flows induced by national economies can be regarded as indirect pressure indicators for environmental degradation. Economy-wide material flow analysis and indicators have been designed to monitor material and energy flows at the macroeconomic level and to provide indicators, which could contribute to management of resourceuse and output emission flows from both economic, environmental and broader sustainability points of view. These indicators can serve various purposes including monitoring the material basis of national economies and related environmental pressures, assessment of the material and resource productivity and monitoring the implications of trade and globalisation.
The main part of this paper compares the material and resourceuse of the Czech Republic, Germany and the EU-15 by means of DMI and TMR indicators over the period of 1991–2004 (1991–2000 for EU-15). At the aggregate level both indicators in all three economies do not show any clear decreasing or increasing trends over the period considered. This means that environmental pressure related to use of materials for production and consumption purposes remains rather stable. All the economies however, recorded an increase in the efficiency of transforming the material/resource inputs into economic output. The analysis further revealed that most of the dynamics of DMI and TMR in the Czech Republic tended towards a higher similarity with Germany and the EU-15. In the future, further decreases in DMI as well as in TMR of fossils fuels might be expected in the Czech Republic, which could be counteracted by increase in DMI and TMR of metal ores/metal resources and non-metallic minerals/non-metallic resources. The future development of total DMI, TMR and material/resource intensity in both the Czech Republic and Germany will depend on further shifts to less material intensive industries and services and on increasing material efficiency in production and consumption of particular products. This is not only a technological, but also a social challenge, as there are barriers in current mode of governance and in shaping of current economic and social systems to do so.
