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.
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.
Resource use of wind farms in the German North Sea : the example of Alpha Ventus and Bard Offshore I
(2013)
The German government aims to obtain at least 40 percent of its electricity from renewable sources by 2030. One of the central steps to reach this target is the construction of deep sea offshore wind farms. The paper presents a material intensity analysis of the offshore wind farms "Alpha Ventus" and "Bard Offshore I" under consideration of the grid connection. An additional onshore scenario is considered for comparison. The results show that offshore wind farms have higher resource consumption than onshore farms. In general, and in respect to the resource use of other energy systems, both can be tagged as resource efficient.
The need for recycling obsolete mobile phones has significantly increased with their rapidly growing worldwide production and distribution. Return and recycling rates are quite low; people tend to keep old, unused phones at home instead of returning them for recycling or further use because of a lack of knowledge and acceptance of return programmes. Thus far, individual use and recycling behavior has not shown any trend towards more sustainable patterns. Consequently, an increased awareness is needed for the high environmental and social impact throughout the whole value chain of a mobile phone - there is simply a lack of information and knowledge regarding sustainability issues around the mobile phone. A teaching material was therefore developed in a German research project, based on the concept of the ecological rucksack, presenting comprehensive information about the value chain of a mobile phone. Its application in different schools led to an increased awareness and interest among pupils for the connection between sustainability, resources and mobile phones. Based on these research results, this paper analyses young people’s knowledge of sustainability issues linked to their mobile phones and their acceptance of more sustainable behavioral patterns regarding their mobile, including return and recycling programmes.
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.
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 electricity market is linked to a carbon market with a fixed cap that limits greenhouse gas emissions. At the same time, a number of energy efficiency policy instruments in the EU aim at reducing the electricity consumption. This article explores the interactions between the EU's carbon market on the one hand and instruments specifically targeted towards energy end-use efficiency on the other hand. Our theoretical analysis shows how electricity demand reduction triggered by energy efficiency policy instruments affects the emission trading scheme. Without adjustments of the fixed cap, decreasing electricity demand (relative to business-as-usual) reduces the carbon price without reducing total emissions. With lower carbon prices, costly low emission processes will be substituted by cheaper high emitting processes. Possible electricity and carbon price effects of electricity demand reduction scenarios under various carbon caps are quantified with a long-term electricity market simulation model. The results show that electricity efficiency policies allow for a significant reduction of the carbon cap. Compared to the 2005 emission level, 30% emission reductions can be achieved by 2020 within the emission trading scheme with similar or even lower costs for the industrial sector than were expected when the cap was initially set for a 21% emission reduction.
The Durban Climate Conference agreed on the creation of a new market-based mechanism under the United Nations Framework Convention on Climate Change (UNFCCC) and to consider the establishment of an overall framework for various mitigation approaches, including opportunities for using markets ("Framework"). The creation of such a Framework is therefore of high political significance, as it should ensure on the one hand that new market-based mechanisms contribute to global climate change mitigation and to achievement of targets, and on the other hand, that different market-based approaches can be integrated in a global carbon market. As yet, there is little clarity as to the roles and design of such a framework. This paper contributes to the debate by discussing and evaluating inter alia several design options, and explores how the various options could be implemented and how they interrelate. It concludes that a strong central oversight at the level of the UNFCCC is probably the only option that could reassure the vast majority of UNFCCC Parties that the environmental integrity of new market-based mechanisms is in fact ensured. This does, however, not exclude that some reasonable balance may be struck between centralization and flexibility.
Apart from the much-debated question of what legal form the 2015 climate agreement is supposed to have, another core issue is the substantive content of countries' commitments. While the climate regime has so far mostly been based on emission targets, literature has identified a broad range of other possible types of mitigation commitments, such as technology targets, emission price commitments, or commitments to specific policies and measures (PAMs). The nationally appropriate mitigation actions (NAMAs) submitted by developing countries under the Cancún Agreements also show a broad range of different forms of participation. This article surveys the possible commitment types that have so far been discussed in literature and in the UNFCCC negotiations and assesses their respective advantages and disadvantages against a set of criteria: environmental effectiveness, cost effectiveness, distributional aspects and institutional feasibility. The article finds that no commitment option provides a silver bullet. All options have several advantages but also disadvantages. The environmentally most effective way forward may lie in pursuing a multi-dimensional approach, combining emission targets with other commitment types to compensate for the drawbacks of the emission-based approach. However, such an approach would also increase complexity, both in terms of the negotiations and in terms of implementation and administration.

This report lays out the major developments in Durban and assesses the main outcomes. It is structured along the Bali roadmap for a future climate agreement that was agreed at the Bali climate conference in 2007. The Bali roadmap comprises negotiations under two tracks. First, the Ad Hoc Working Group on Further Commitments by Annex I Countries under the Kyoto Protocol (AWG-KP), established at the conference in Montreal in 2005, has been negotiating future emission targets for developed countries (listed in Annex I of the United Framework Convention on Climate Change (UNFCCC) and hence called Annex I countries). As the Kyoto Protocol's first commitment period expires in 2012, the AWG-KP is to agree on new targets for a second commitment period post-2012 as well as associated rules for accounting emissions. Second, the Ad Hoc Working Group on Long-term Cooperative Action under the Convention (AWG-LCA) has also been negotiating commitments for Annex I countries, intending to cover those that have not ratified the Protocol - that is, the USA. In addition, the LCA negotiates "Nationally appropriate mitigation actions" of developing countries, which are to be supported by Annex I countries with technology, financing and capacity-building. Both the actions and the support are to be "measurable, reportable and verifiable". The LCA also negotiates how such support for developing countries' mitigation actions may be delivered as well as how developing countries may be supported in adapting to the impacts of climate change.

The eighteenth Conference of the Parties (COP 18) to the United Nations Framework Convention on Climate Change (UNFCCC) and the ninth Conference of Parties serving as the Meeting of the Parties to the Kyoto Protocol (CMP 8) came to a close in the evening of 8 December 2012. This report lays out the main developments in Doha and assesses the main outcomes. The first chapter outlines the overall situation coming into Doha. The subsequent chapters cover the negotiations on the future of the Kyoto Protocol, the discussions under the Durban Platform on developing a new comprehensive climate agreement by 2015 and increasing short-term ambition, and further near-term action under the UNFCCC.
Die Suche nach einem Ausweg aus den festgefahrenen Klima- verhandlungen ist derzeit eine der wichtigsten Aufgaben der internationalen Politik. Franz Josef Radermacher (2013) versucht, so einen Weg aus dem Politikstau aufzuzeigen: In verstärktem Ausmaß sollten Privatakteure eingebunden werden und Klimaschutzmaßnahmen finanzieren, weil die internationale Staatengemeinschaft bisher daran gescheitert sei, ein Folgeabkommen für das Kyoto-Protokoll abzuschließen. Von der Staatengemeinschaft verlangt Radermacher nur noch, überhaupt irgendein Abkommen zuwege zu bringen, das die globalen Emissionen zumindest einigermaßen deckelt. Weitere Emissionsreduktionen, die "Verhandlungslücke", sollen Unternehmen und Privatpersonen übernehmen, indem sie freiwillig Emissionszertifikate im Umfang von mehreren hundert Milliarden Tonnen CO2 kaufen und stilllegen. Darüber hinaus sollen weitere 150 Milliarden Tonnen CO2 über Aufforstungsprojekte aus der Atmosphäre herausgeholt werden (Sequestrierung).
The 2011 Japanese earthquake and tsunami, and the consequent accident at the Fukushima nuclear power plant, have had consequences far beyond Japan itself. Reactions to the accident in three major economies Japan, the UK, and Germany, all of whom were committed to relatively ambitious climate change targets prior to the accident are examined. In Japan and Germany, the accident precipitated a major change of policy direction. In the UK, debate has been muted and there has been essentially no change in energy or climate change policies. The status of the energy and climate change policies in each country prior to the accident is assessed, the responses to the accident are described, and the possible impacts on their positions in the international climate negotiations are analysed. Finally, the three countries' responses are compared and some differences between them observed. Some reasons for their different policy responses are suggested and some themes, common across all countries, are identified. Policy relevance: The attraction of nuclear power has rested on the promise of low-cost electricity, low-carbon energy supply, and enhanced energy independence. The Fukushima accident, which followed the Japanese tsunami of March 2011, has prompted a critical re-appraisal of nuclear power. The responses to Fukushima are assessed for the UK, Germany, and Japan. Before the accident, all three countries considered nuclear as playing a significant part in climate mitigation strategies. Although the UK Government has continued to support nuclear new build following a prompt review of safety arrangements, Japan and Germany have decided to phase out nuclear power, albeit according to different timescales. The factors that explain the different decisions are examined, including patterns of energy demand and supply, the wider political context, institutional arrangements, and public attitudes to risk. The implications for the international climate negotiations are also assessed.
Die "Große Transformation" erfordert neue Formen des Wissens und der Integration von Wissen. Die sich ergebenden Herausforderungen lassen sich mit dem Begriff der transformative literacy rahmen. Sie beschreibt die Fähigkeit, Informationen über gesellschaftliche Veränderungsprozesse zu verstehen und eigenes Handeln in diese Prozesse einzubringen. Sie hat eine technologische, ökonomische, institutionelle und kulturelle Dimension - wobei oft die technologische Sicht auf Veränderungsprozesse dominiert. Um die "Große Transformation" zu meistern, muss dieses Ungleichgewicht beseitigt werden.
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.
Assessing the natural resource use and the resource efficiency potential of the Desertec concept
(2013)
Considering global warming, increasing commodity prices, and the dramatic consequences of the over-exploitation and overuse of resources, a transition to a renewable energy supply is necessary. This requires an (resource) efficient and renewable supply of operating reserve. In this article, a possible solution to this problem is analysed: the Desertec concept. It is meant to convert solar energy in areas with high solar irradiation into electrical energy by means of Concentrated Solar Power (CSP) transferring this energy by High Voltage Direct Current (HVDC) lines into the whole European Union Middle East and North Africa (EU-MENA) area. In order to assess the resource efficiency potential of Desertec, three different kinds of CSP plants (parabolic trough, Fresnel collector and central receiver of the building classes Inditep, Novatec and Solar Tres) including heat storage systems (Molten Salt and Phase-Changing-Material) and the necessary HVDC are analysed using the Material Input per Service Unit (MIPS) methodology. The assessment is accomplished for three different locations (Morocco, Tunisia and Egypt) and two points of time (2025 and 2050). With these results, a scenario of electricity supply in Germany in 2050 with a 20% share of solar power import is calculated. Central receivers are the most resource efficient ones: their consumption of abiotic materials is only half of parabolic trough plants and two thirds of Fresnel trough plants. Water and air consumption is the lowest of all analyzed CSP plants as well. The scenario for Germany's fuel mix in 2050 shows that a predominantly renewable fuel mix reduces the consumption of abiotic materials by 75%, of water by 60% and of air by 45%. Only the consumption of biotic materials rises due to the higher share of biomass conversion.
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.
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.
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.
Both focus group discussions and information-choice questionnaires (ICQs) have previously been used to examine informed public opinions about carbon dioxide capture and storage (CCS). This paper presents an extensive experimental study to systematically examine and compare the quality of opinions created by these two research techniques. Depending on experimental condition, participants either participated in a focus group meeting or completed an ICQ. In both conditions participants received identical factual information about two specific CCS options. After having processed the information, they indicated their overall opinion about each CCS option. The quality of these opinions was determined by looking at three outcome-oriented indicators of opinion quality: consistency, stability, and confidence. Results for all three indicators showed that ICQs yielded higher-quality opinions than focus groups, but also that focus groups did not perform poor in this regard. Implications for the choice between focus group discussions and ICQs are discussed.
