LinkLab is a newly established working group under the umbrella of German Committee Future Earth (DKN Future Earth). It opens up a space to discuss relevant connections and interfaces between real-world lab research and various scientific disciplines, exploring fruitful connections and pathways for mutual learning for future sustainability-oriented research.
Das Ernährungssystem steht vor einer Vielzahl von Herausforderungen, wie unter anderem: hoher Treibhausgas-Emissionen, der Gefährdung der Biodiversität, der vermehrten ernährungsbedingten Krankheiten durch unausgewogener Ernährung sowie sozial-problematischen komplexen Lieferketten. Das erfordert nicht nur eine Transformation der Agrarwirtschaft sondern auch einen Wandel in den Ernährungs- und Lebensstilen aller Konsumierenden. Digitale und technologische Innovationen zu nutzen und weiterzuentwickeln kann helfen, diese Herausforderungen zu lösen. Vor diesem Hintergrund liefert die vorliegende Studie des Wuppertal Instituts Impulse, wie die Digitalisierung dazu beitragen kann Produktion und Konsum umzugestalten und welche Voraussetzungen dafür gegeben sein müssen.
Die Studie beschreibt die Ansatzpunkte für die Digitalisierung entlang der Wertschöpfungskette. Dazu zählen die Optimierung des Ressourceneinsatzes in der Landwirtschaft, etwa mithilfe von Smart Farming, die Unterstützung von Verbraucher*innen durch digitale Tools und Assistenzsysteme - beispielsweise mit Apps als Einkaufshilfe. Daneben erlauben auch neue Geschäftsmodelle und Rahmenbedingungen eine bessere Vernetzung von Produktions- und Konsumprozessen. Dazu gehören zum Beispiel neue digitale Absatzkanäle oder Prozessstufen-übergreifend Nachhaltigkeitskennzahlen wie beispielsweise CO2-Emissionen mitzuführen und zu kommunizieren, um allen Akteur*innen richtungssicheres Handeln zu ermöglichen.
The food system faces a multitude of challenges, including high greenhouse gas emissions, threats to biodiversity, increased diet-related diseases due to unbalanced diets, and socially problematic complex supply chains. This requires not only a transformation of the agricultural economy but also a change in the diet and lifestyles of all consumers. Developing and using digital and technological innovations can help to solve these challenges. In this context, the study provides impulses on how digitalisation can contribute to transforming production and consumption and which prerequisites have to be given to achieve this.
The study describes the approaches for digitalisation along the value chain. These include optimising the use of resources in agriculture - for example with the help of smart farming - and supporting consumers with digital tools and assistance systems - such as apps designed to support grocery shopping. In addition, new business models and a better connection between production and consumption processes are also possible. This includes, for example, new digital sales channels or tracking and communicating sustainability indicators such as CO2 emissions across all steps of the value chain in order to enable all stakeholders to take reliable action.
Food and nutrition systems are linked to all Sustainable Development Goals (SDGs), which makes their transition toward social-ecological behavior patterns crucial for an overarching sustainability transformation. The perspective of (urban) logistics is of special interest. It couples the production and consumption physically and virtually. In this context, we shed light on the design of the turnover point of food in urban areas from the supply chain toward consumers and contribute to an overarching systemic perspective toward establishing a sustainable multilevel food system. We describe current patterns in urban food systems and propose several principles for sustainable design of (urban) food systems based on concepts such as (regional) collaboration and food literacy. Using these principles, we provide four design scenarios that concretely imagine future urban food consumption and production patterns titled "slow stock supply service," "deliver into the daily walk," "central district food depot," "super food action place." With this work we provide a starting for reflecting whether certain combinations of principles actually lead to patterns of daily life that are feasible, acceptable, or desirable. Moreover, we provide an initial qualitative assessment to stimulate further research that explores scenario pathways and incorporates additional indicators regarding the impact on social-ecological. We open up various research questions with regard to the overarching question of how urban food logistics should be designed to be consistent with the SDGs.
Vor dem Hintergrund der zunehmenden Auswirkungen der Klimakrise und der durch den Angriffskriegs Russlands gegen die Ukraine entstandenen Energie- und Rohstoffversorgungsprobleme ist die Bundesregierung zu einem schnellen und zielführenden Handeln gezwungen. Neben der Herstellung von Versorgungssicherheit müssen die durch stark steigende Energie- und Lebensmittelpreise entstehenden sozialen Härten abgefedert werden. Um diese Aufgabe bestmöglich zu bewältigen, bedarf es eines politischen Instruments, das notwendige Veränderungen der Lebens- und Wirtschaftsweise ermöglicht und soziale Belastungen in den Krisen auffängt.
Mit Blick auf diese Problemstellung werden in diesem Wuppertal Report bereits vorhandene politische Instrumente, deren Mittel nicht zweckgebunden verwendet werden müssen, einer SWOT-Analyse unterzogen und erste Ideen für ein sogenanntes Transformationsgeld vorgestellt, das die Mehrdimensionalität der derzeitigen Problemlage berücksichtigt. Das Transformationsgeld ist als zweckungebundene staatliche Transferleistung konzipiert, um die Freiheit der Konsument*innen nicht einzuschränken und Preiseffekte nicht zu nivellieren. Die Höhe der Transferleistung hängt von der ökonomischen Situation des Haushalts ab und soll nicht nur eine Kompensation der Mehrkosten darstellen, sondern gesellschaftliche Teilhabe ermöglichen.
Abseits des Transformationsgelds liefert die Kurzstudie auch eine Einschätzung der Autor*innen, was aus ihrer Sicht kurzfristig gegen die bestehenden Probleme getan werden sollte.
Das Fortschreiten des Klimawandels und die Schädigung der Ökosysteme machen deutlich, dass die seit Jahrzehnten international geforderte nachhaltige Entwicklung zu den wichtigsten Herausforderungen gehören.
Um die von den Vereinten Nationen in der Agenda 2030 festgeschriebenen Nachhaltigkeitsziele, den sogenannten Sustainable Development Goals (SDGs), zu erreichen, sind alle relevanten Akteurinnen und Akteure - die Politik, die Wirtschaft sowie jede und jeder Einzelne - gefragt.
Eine nachhaltige Entwicklung, die zugleich Umweltschonung, stabile wirtschaftliche und gesellschaftliche Entwicklung sowie soziale Gerechtigkeit berücksichtigt, beruht damit auf der Kompetenz oder auch der "Literacy" der Einzelnen, für sich und im Kollektiv nachhaltiges Handeln auszuüben und im gegenseitigen Miteinander fördern zu können. Doch welche Fähigkeiten sind notwendig, um nachhaltig Handeln zu können? Welche Fähigkeiten brauchen insbesondere Konsumentinnen und Konsumenten, um ihre Produktions- und Konsummuster nachhaltiger (mit-)gestalten zu können?
Antworten darauf liefert die "Literacy für nachhaltigen Konsum", die in dem vorliegenden Diskussionspapier entwickelt und vorgestellt wird.
Quantitative environmental assessments are crucial in working effectively towards sustainable production and consumption patterns. Over the last decades, life cycle assessments (LCA) have been established as a viable means of measuring the environmental impacts of products along the supply chain. In regard to user and consumption patterns, however, methodological weaknesses have been reported and, several attempts have been made to improve LCA accordingly, for example, by including higher order effects and behavioural science support. In a discussion of such approaches, we show that there has been no explicit attention to the concepts of consumption, often leading to product-centred assessments. We introduce social practice theories in order to make consumption patterns accessible to LCA. Social practices are routinised actions comprising interconnected elements (materials, competences, and meanings), which make them conceivable as one entity (e.g. cooking). Because most social practices include some sort of consumption (materials, energy, air), we were able to develop a framework which links social practices to the life cycle inventory of LCA. The proposed framework provides a new perspective of quantitative environmental assessments by switching the focus from products or users to social practices. Accordingly, we see the opportunity in overcoming the reductionist view that people are just users of products, and instead we see them as practitioners in social practises. This change could enable new methods of interdisciplinary research on consumption, integrating intend-oriented social sciences and impact-oriented assessments. However, the framework requires further revision and, especially, empirical validation.
The demand for metals from the entire periodic table is currently increasing due to the ongoing digitalization. However, their use within electrical and electronic equipment (EEE) poses problems as they cannot be recovered sufficiently in the end-of-life (EoL) phase. In this paper, we address the unleashed dissipation of metals caused by the design of EEE for which no globally established recycling technology exists. We describe the European Union's (EU) plan to strive for a circular economy (CE) as a political response to tackle this challenge. However, there is a lack of feedback from a design perspective. It is still unknown what the implications for products would be if politics were to take the path of a CE at the level of metals. To provide clarification in this respect, a case study for indium is presented and linked to its corresponding recycling-metallurgy of zinc and lead. As a result, a first material-specific rule on the design of so-called "anti-dissipative" products is derived, which actually supports designing EEE with recycling in mind and represents an already achieved CE on the material level. In addition, the design of electrotechnical standardization is being introduced. As a promising tool, it addresses the multi-dimensional problems of recovering metals from urban ores and assists in the challenge of enhancing recycling rates. Extending the focus to other recycling-metallurgy besides zinc and lead in further research would enable the scope for material-specific rules to be widened.
The earth's capacity to absorb greenhouse gases is ultimately a critical limiting factor in the handling of metals. The fact that the demand for metals far exceeds their secondary production is extremely problematic at this point. Nevertheless, metals are crucial for climate protection and energy system transformation. Examples are the rare earth metal neodymium used in high-performance permanent magnets in wind turbines, the alkali metal lithium as the most important component in batteries, or the metal tellurium used in thin-film solar cells to generate solar power. It is therefore essential to promote the aspects of resource efficiency and to strengthen the critical role of metals in national and European policy programs. Next to a global solution, a European solo effort with predominantly market-based instruments and the effects of committed behaviour by civil society in the European Union (EU), show that the EU can make a considerable contribution to sustainable development on its own. Thus, a comprehensive approach is needed for sustainable metal management in the sense of a circular economy on the European level fostering sustainable production and consumption pathways. But, this need and the special role of metals are not seen in the current debate about resources in society and politics. Due to the fact that in public perception, metallic raw materials are often discussed as less urgent than energy or polymer raw materials, this article aims to highlight the critical role of metals.
Further, the objective of this contribution is to show which prerequisites exist for the development and establishment of a holistic metal management and where political strategies have to start. Challenges needed to be overcome to achieve such a holistic metal strategy and management are highlighted. In particular, the role of the metal industry, circular product design and labelling and corresponding indicator systems is examined. In addition, the special role of digitalisation is being worked out. Finally, conclusions are drawn and shown which aspects have to be considered for a holistic metal strategy and management.
Sustainable consumption policies affect households differently, in particular when they are confronted with limitations on income, time or freedom of movement (e.g. driving to work). And although it is possible to assess either the average or individual material footprint (per capita or via surveys), we lack methods to describe different types of households, their lifestyles and footprints in a representative manner.
We explore possibilities to do so in this article. Our interest lies in finding an applicable method that allows us to describe the footprint of households regarding their socio-demographic characteristics but also find the causes consumption behaviour. This type of monitoring would enable us to tailor policies for sustainable consumption that respect people's needs and restrictions.
In this paper, we aim to present a comprehensive analysis on the emerging phenomenon of distributed innovation in commons-based peer production (CBPP) platforms. Starting with the exploration of the widely held belief on value-creation confined to industrial settings, we raise several questions regarding the feasibility of, and a need for, an inclusive innovation process that can tap grassroots capacity into both traditional (industrial research and development) and emerging (peer-to-peer) innovation models to yield sustainable solutions. In particular, we explore the emergence and structuration of digital innovations in the maker movement, as it presents an alternative construct of innovation wherein access to and sharing of knowledge is predominantly distributed. With innovation outcomes often freely revealed, its very structuration could pose a principal challenge to our conceptualizations of value creation and competitive advantage in the current economic model. Drawing from responses received from 200 collaborative innovation platforms, six semi‐structured interviews focusing on socio-technical innovation cases, as well as four in-depth narrative interviews with maker turned entrepreneurs, we present a detailed analysis on the topology of network, typology of actors, as well as the underlying innovation ecosystem in CBPP networks in Germany. In doing so, we contribute to the conceptualization of peer-to-peer distributed innovations in collaborative platforms.
Sustainable supply chains : global cooperative regional economies for prosperity and resilience
(2021)
Two thirds of today's world trade is based on global value chains and supply networks. Purely regional supply chains have become less important in recent decades. The effects of these globalised structures are manifold. On the one hand, they promote employment and generate prosperity. On the other hand, they are beset by extreme social, ecological and economic imbalances.
The COVID-19 pandemic has demonstrated the fragility of existing supply chain systems. The lockdown continues to disrupt complex supply chains and many problems of existing production and consumption continue to worsen. COVID-19 is one example of the crises that can shake globally networked supply chains in the short term. Other crises, such as climate change, develop more insidiously and are less immediately recognisable. Different as they are, such crises have one thing in common: they highlight the vulnerability of global social and economic structures and illustrate the impact of global trade on the regions and people of the world.
This is precisely where global sustainability strategy comes in - it aims to fundamentally reduce differences and inequalities in opportunities and quality of life. The COVID-19 pandemic has forced the entire world into upheaval, creating an opportunity to make sustainability a central political resilience strategy.
In the wake of the Corona pandemic, the discussion about resilient communities has flared up. In order to guarantee supply in the face of such crises, these should be more strongly regional and circular in their economic approach and global and sustainable in their perspective. The aim should be sustainable, transparent, non-exploitative supply chains that guarantee the security of supply to cover basic needs and public services despite sudden changes and crises.
This discussion paper draws a future scenario of globally cooperative, circular regional economies that fundamentally reduce global inequalities in opportunities and quality of life, while at the same time permanently preserving the natural foundations of life.
Arbeit ist das halbe Leben?! : Über ein neues Statussymbol ; die Zeit und was wir damit anfangen
(2021)
Nutrition is one of the most important areas for the great transformation. So how can a shift towards a sustainable food system be achieved? This paper addresses this question - based on more than ten years of research on sustainable nutrition at the Wuppertal Institute. It focuses on public catering, because even small changes - for example in the choice of ingredients - have a huge impact here. With appropriate policy frameworks, public catering can serve as an easily accessible place for consumers to experience sustainable food and at the same time be a reliable buyer of biodiversity and climate-friendly food from farmers. However, other actors are also needed for a transformation of the food system: The "Zukunftsimpuls" addresses politics, (agricultural) industry, science and every individual - because the transformation of the food system is a task for the entire society.
Ernährung ist einer der wichtigen Bereiche für die große Transformation. Doch wie kann eine Umstellung auf ein nachhaltiges Ernährungssystem gelingen? Der vorliegende Zukunftsimpuls setzt sich mit dieser Frage auseinander - basierend auf über zehn Jahren Forschung zu nachhaltiger Ernährung am Wuppertal Institut. Einen Schwerpunkt setzt das Papier auf die Außer-Haus-Gastronomie, denn bereits kleine Umstellungen - etwa in der Zutatenauswahl - haben hier große Wirkung. Mit geeigneten Rahmenbedingungen kann die Außer-Haus-Gastronomie den Konsumierenden als leicht zugänglicher Erlebnisort für nachhaltigere Ernährung dienen und gleichzeitig Landwirtinnen und Landwirten ein zuverlässiger Abnehmer für biodiversitätsschonende und klimafreundliche Lebensmittel sein. Doch für eine Transformation des Ernährungssystems sind auch andere Akteure gefragt: Der Zukunftsimpuls adressiert Politik, (Land-)Wirtschaft, Wissenschaft und jeden und jede Einzelne - denn die Transformation des Ernährungssystems ist eine gesamtgesellschaftliche Aufgabe.
Die aktuellen Berichte des Weltklimarates (Intergovernmental Panel on Climate Change, IPCC) und des International Resource Panel zeigen erneut die Dringlichkeit einer umfassenden sozial-ökologischen Transformation auf. Das bedeutet, dass die Umsetzung der "Agenda 2030", welche im Jahr 2015 durch die Vereinten Nationen beschlossen wurde, als ein international geltendes Maßnahmenprogramm zur Umsetzung einer nachhaltigen Entwicklung gesetzt und ihr ein zentraler politischer Stellenwert zugeordnet werden muss. Das SDG 12 "Nachhaltige Konsum- und Produktionsmuster sicherstellen" setzt die besondere Rolle nachhaltiger Produktions- und Konsummuster als Ausgangspunkt für eine Klima- und Ressourcenwende und Generationen- sowie soziale Gerechtigkeit.
Der Zukunftsimpuls formuliert zehn Botschaften zur Umsetzung von SDG 12 "Nachhaltige Konsum- und Produktionsmuster sicherstellen" als Ausgangspunkt einer großen Transformation. Es beleuchtet kurz und knapp vielfältige Handlungsvoraussetzungen als auch Akteurinnen und Akteure, die relevant für die Verwirklichung einer nachhaltigen Zukunft sind.
Der Zukunftsimpuls thematisiert unter anderem die Vorbildfunktion des Staates, die Chancen, die sich auf kommunaler Ebene bieten und die internationale Perspektive, welche sich durch globale Kooperationen und stetigen Wissens- und Erfahrungsaustausch auszeichnen sollte. Ein weiterer Fokus liegt auf nachhaltiger Produktion und nachhaltigem Konsum. Dies lässt sich durch die Stärkung des Nachhaltigkeitsbewusstseins und der -kompetenz sowie der Schaffung von ausreichend Gelegenheiten erreichen, damit einer dynamisch wachsenden Gruppe nachhaltiges Produzieren und nachhaltiger Konsum ermöglicht wird. Ziel ist daher die Bildung eines politischen und gesetzlichen Rahmens, welcher nachhaltige Lebensstile als auch nachhaltige Produktions- und Dienstleistungssysteme begünstigt, fördert und als Daseinsvorsorge sieht. Um die Entwicklung und Fortschritte zu sichern, bedarf es neuer Indikatoren und regelmäßiger Monitorings, die Handlungslücken in Realzeit aufdecken und das Schließen der Lücken ermöglichen. Die Umsetzung des SDG 12 benötigt einen Rahmen, der von Politik, Wirtschaft und Gesellschaft getragen wird.
Nachhaltige Lieferketten : global kooperative Regionalwirtschaften für Wohlstand und Resilienz
(2020)
Zwei Drittel des heutigen Welthandels gründen auf globalen Wertschöpfungsketten und Versorgungsnetzen. Rein regionalwirtschaftlich organisierte Lieferketten haben in den letzten Jahrzehnten an Bedeutung verloren. Die Auswirkungen dieser globalisierten Strukturen sind vielfältig: Zum einen haben sie beschäftigungsfördernde Effekte und wirken wohlstandsstiftend. Zum anderen existieren entlang der Lieferketten extreme soziale, ökologische und ökonomische Schieflagen.
Die COVID-19-Pandemie zeigt in erheblichem Maße, wie fragil bestehende Lieferkettensysteme sind. Der Lockdown unterbricht noch immer komplexe Lieferketten und viele Probleme der bestehenden Produktions- und Konsumweise verschärfen sich weiterhin. COVID-19 ist ein Beispiel einer der möglichen Krisen, welche die globalen und vernetzten Wertschöpfungsketten kurzfristig erschüttern kann. Andere Krisen entwickeln sich schleichender und damit weniger schnell erkennbar, wie etwa der globale Klimawandel. So unterschiedlich sie sind, haben die Krisen eines gemein: Sie zeigen die Verletzlichkeit globaler Gesellschafts- und Wirtschaftsstrukturen auf und verdeutlichen die Wirkungen globalen Handels auf die Regionen und Menschen der Welt.
Die globale Nachhaltigkeitsstrategie setzt genau hier an - sie zielt darauf ab, Unterschiede und Ungleichheit in Chancen und Lebensqualität grundlegend zu vermindern. Deshalb sollte die Umsetzung der Nachhaltigkeitsziele auf internationaler, nationaler und regionaler Ebene eine Antwort auf solche Krisen sein. Da durch die Covid-19-Pandemie zeitgleich die komplette Welt in eine Umbruchsituation gedrängt wurde, bietet die Reaktion darauf an, Nachhaltigkeit als zentrale politische Resilienz-Strategie zu nutzen.
Im Zuge der Corona-Pandemie flammte die Diskussion um resiliente Kommunen auf. Diese sollten sich stärker an regional- und kreislaufwirtschaftlichen Ansätzen orientieren, um angesichts solcher Pandemien die Versorgung weiterhin gewährleisten zu können. So wichtig und richtig die Entwicklung eigener regionalwirtschaftlicher und kreislauforientierter Ansätze im Kern ist, so wenig resilient ist es, wenn deren Entwicklung nicht unter globaler und nachhaltiger Perspektive erfolgt. Ziel sollten menschengerechte, nachhaltige und transparente Lieferketten sein, die auch bei plötzlich veränderten Rahmenbedingungen und Krisen richtungssicher die Versorgungssicherheit zur Deckung von Grundbedürfnissen und Daseinsvorsorge sicherstellen können.
Das vorliegende Diskussionspapier zeichnet als Zukunftsszenario global kooperative, kreislauforientierte Regionalwirtschaften, die weltweite Ungleichheiten in Chancen und Lebensqualität grundlegend vermindern und dabei gleichsam die natürlichen Lebensgrundlagen dauerhaft bewahrt werden.
Die Wirtschaftsleistung von Deutschland ist durch die Corona-Pandemie stark beeinträchtigt. Um die Wirtschaft zu beleben, einigten sich die Regierungsparteien am 3. Juni 2020 in ihrem Koalitionsausschuss auf ein "Konjunktur- und Krisenbewältigungspaket" sowie ein "Zukunftspaket" in Höhe von insgesamt 130 Milliarden Euro. Für 2020 und 2021 sind fast 60 Maßnahmen vorgesehen, die von steuerlichen Vergünstigungen bei der Mehrwertsteuer bis hin zu konkreten Investitionen in Zukunftstechnologien reichen. Mit Blick auf den Klimaschutz beinhaltet das Maßnahmenpaket der Großen Koalition zwar gute Ansätze und viele wichtige Impulse, die allerdings zu verpuffen drohen, wenn sie nicht durch eine konsequente und nachhaltig ausgerichtete Klimapolitik flankiert werden. Zudem fehlen für den Klimaschutz wichtige Bereiche, wie Investitionen in die Kreislaufwirtschaft. Außerdem werden Maßnahmen zur Steigerung der Energieeffizienz nur unzureichend berücksichtigt. Gerade in diesen Bereichen hätten sich konjunkturbelebende Effekte und Klimaschutz in idealer Form ergänzen können, kritisiert das Wuppertal Institut. Dieses Diskussionspapier reagiert auf die vorliegenden Vorschläge und fasst zusammen, welche Maßnahmen im Rahmen der jetzt anstehenden Umsetzungsphase nachgebessert werden sollten und wo Ergänzungen notwendig sind.
Was hat Design mit Umwelt und Nachhaltigkeit zu tun? Die globale Erwärmung und der Klimawandel lassen sich auf verschiedene Ursachen zurückführen. Design, das die Umwelt außen vor lässt, ist einer der Gründe. Viele Produkte und Dienstleistungen verbrauchen nämlich viel Energie und Ressourcen haben auch eine hohe soziale Relevanz - sie sorgen beispielsweise für Teilhabe oder Exklusion. Wie eine Transformation hin zu mehr Nachhaltigkeit in diesem Bereich besser gelingt, fasst der neue "Transition Design Guide" des Wuppertal Instituts und der Folkwang Universität der Künste in Kooperation mit der ecosign - Akademie für Gestaltung Köln und der Bergischen Universität Wuppertal zusammen.
Der Leitfaden gibt interessierten Gestaltenden, Entwickelnden, Transformatorinnen und Transformatoren sowie Forschenden in Universitäten, Unternehmen und Kommunen 16 Praxis-Werkzeuge an die Hand, um Produkte, Dienstleistungen, soziale Räume oder andere Erfahrungswelten nachhaltiger und umweltbewusster zu entwerfen. Anhand der Arbeitsblätter lassen sich gestalterische Ideen und Konzepte auf ihre Nachhaltigkeitspotenziale untersuchen und weiterentwickeln. Nachhaltigkeitsaspekte werden dabei mit den Methoden und Arbeitsschritten eines klassischen Designprozesses zusammengeführt. Ausführliche Hintergrundinformationen ergänzen die Themen der Tools inhaltlich.
Recent research on the natural resource use of private consumption suggests a sustainable Material Footprint of 8 tons per capita by 2050 in industrialised countries. We analyse the Material Footprint in Germany from 2015 to 2020 in order to test whether the Material Footprint decreases accordingly. We studied the Material Footprint of 113,559 users of an online footprint calculator and predicted the Material Footprint by seasonally decomposed autoregressive (STL-ARIMA) and exponential smoothing (STL-ETS) algorithms. We find a relatively stable Material Footprint for private consumption. The overall Material Footprint decreased by 0.4% per year between 2015 and 2020 on average. The predictions do not suggest that the Material Footprint of private consumption follows the reduction path of 3.3% per year that will lead to the sustainable consumption of natural resource

This assessment report identifies six key areas of sustainable consumption. Transforming those areas is associated with a significant, positive impact on sustainable development. In this way, those key areas lay the foundation to set clear priorities and formulate concrete policy measures and recommendations. The report describes recent developments and relevant actors in those six fields, outlines drivers and barriers to reach a shift towards more sustainability in those specific areas, and explores international good-practice examples. On top of this, overarching topics in the scientific discourse concerning sustainable consumption (e.g. collaborative economy, behavioural economics and nudging) are revealed by using innovative text-mining techniques. Subsequently, the report outlines the contributions of these research approaches to transforming the key areas of sustainable consumption. Finally, the report derives policy recommendations to improve the German Sustainable Development Strategy (DNS) in order to achieve a stronger stimulus effect for sustainable consumption.
Green Information Systems in general, and footprint calculators in particular, are promising feedback tools to assist people in adopting sustainable behaviour. Therefore, a Material Footprint model for use in an online footprint calculator was developed by identifying the most important predictors of the Material Footprint of the calculator's users. By means of statistical learning, the analysis revealed that 22 of the 95 predictors identified accounted for 74% of the variance in Material Footprints. Ten predictors out of the 95, mainly from the mobility domain, were capable of showing a prediction accuracy of 61%. The authors conclude that 22 predictors from the areas of mobility, housing and nutrition, as well as sociodemographic information, accurately predict a person's Material Footprint. The short and concise Material Footprint model may help developers and researchers to enhance their information systems with additional items while ensuring the data quality of such applications.
Footprint calculators are efficient tools to monitor the environmental impact of private consumption. We present the results of an analysis of data entered into an online Material Footprint calculator undertaken to identify the socioeconomic drivers of the Material Footprint in different areas of consumption, from housing to holidaymaking. We developed regression models to reveal (1) the impact of socioeconomic characteristics on Material Footprints of private households and (2) correlations between the components of Material Footprints for different arrays of consumption. Our results show that an increasing Material Footprint in one array of consumption comes with an increasing Material Footprint in all other arrays, with the exception of housing and holidaymaking. The socioeconomic characteristics of users have a significant impact on their Material Footprints. However, this impact varies by the array of consumption. Households only exhibit generally bigger Material Footprints as a result of higher incomes and larger dwellings. We conclude that indicators which strive to monitor resource efficiency should survey disaggregated data in order to classify the resource use to different population groups and arrays of consumption.
Nowadays, the main impetus to apply additive manufacturing (AM) of metals is the high geometric flexibility of the processes and its ability to produce pilot or small batch series. In contrast, resource and energy intensities are often not considered as constraints, even though the turnout of additive manufacturing is high, at least compared to chip removing processes.
The study at hand analyses the material characteristics and environmental impacts of a hose nozzle as an example of a commercial product of simple geometry. The production routes turning (conventional manufacturing) and laser beam melting (additive manufacturing) are compared to each other in terms of natural resource use, climate change potential and primary energy demand. It is found, that the product shows a lower demand for natural resources when produced via AM, but higher carbon emissions and energy demand when using a steel, that is mainly (80%) produced from high-alloyed steel scrap. However, different case studies during the sensitivity analyses showed that a number of factors highly influence the results: the steel source as well as the source of electricity play a major role in determining the environmental performance of the production routes. The authors also found that other production processes (here cold forging of tubes) might be an eco-friendly alternative to both routes, if feasible from an economic point of view.
In regard to the material characteristics, experimental testing revealed that the material advantages of AM produced hose nozzles (in particular higher yield strength) are reduced after a solution heat treatment is applied to the as-produced material, in order to increase corrosion resistance. However, products that do not require this production step might benefit from the higher yield strength, as a lower wall thickness could be realised.
Digitalisation is disrupting business practices worldwide and transforming consumption patterns. While a global increase in wealth is leading to higher consumption rates, consumption-related decisions are increasingly based on digital information and marketing; furthermore, shopping increasingly takes place online and products and services are more and more digitalised.
The transformative character of digitalisation calls for political action in order to ensure sustainable consumption in a new and dynamically changing context. Focusing on consumption is imperative in combatting many global challenges. Take climate change: consumption-based emissions (i.e. emissions from domestic final consumption and emissions caused by the production of imported goods) are rising more rapidly than production-based emissions in high-income countries. Meanwhile most political measures target production-based emissions (i.e. territorial emissions).
The German council for sustainable development (Rat für Nachhaltige Entwicklung) has called for the §principle of sustainable development [to] serve as the political framework for digital transformation" as "digitalisation has the potential to engender disruptive developments in the business world as well as society as a whole that carry both great opportunities and significant risks". Thus, to implement the 2030 Agenda, in particular SDG 12, and the National Program Sustainable Consumption, it is key to seize the opportunities that digitalisation presents for sustainable consumption and tackle the challenges. This assessment report thus examines the following key question: "What are the implications of the digital transformation of consumption patterns for the implementation of the German sustainability strategy in, by and with Germany?"
The long-term transition towards a low-carbon transport sector is a key strategy in Europe. This includes the replacement of fossil fuels, modal shifts towards public transport as well as higher energy efficiency in the transport sector overall. While these energy savings are likely to reduce the direct greenhouse gas emissions of transport, they also require the production of new and different vehicles. This study analyses in detail whether final energy savings in the transport sector also induce savings for material resources from nature if the production of future vehicles is considered. The results for 28 member states in 2030 indicate that energy efficiency in the transport sector leads to lower carbon emissions as well as resource use savings. However, energy-efficient transport sectors can have a significant impact on the demand for metals in Europe. An additional annual demand for 28.4 Mt of metal ores was calculated from the personal transport sector in 2030 alone. The additional metal ores from semiprecious metals (e.g., copper) amount to 12.0 Mt, from precious metals (e.g., gold) to 9.1 Mt and from other metals (e.g., lithium) to 11.7 Mt, with small savings for ferrous metal ores (-4.6 Mt).
The paper describes patterns of resource use related to German households' equipment. Using cluster analysis and material flow accounting, data on socio-demographic characteristics, and expenditures on fuel, electricity and household equipment allow for a differentiation of seven different household types. The corresponding resource use, expressed in Material Footprint per person and year, is calculated based on cradle-to-gate material flows of average household goods and the related household energy use. Our results show that patterns of resource use are mainly driven by the use of fuel and electricity and the ownership of cars. The quantified Material Footprints correlate to social status and are also linked to city size, age and household size. Affluent, established and/or younger families living in rural areas typically show the highest amounts of durables and expenditures on non-durables, thus exhibiting the highest use of natural resources.
Nutrition is responsible for about 30% of global natural resource use. In order to limit the negative impact the nutritional sector has on the environment and on society, the consumption and processing of foodstuffs with assumed low negative impact is an important topic in the effort of sustainable development. In professional kitchens, clearly defined indicators assessing the impact of business activities are needed in this effort. The research and development in the NAHGAST project provides groundwork that could be of important assistance in this effort. Two versions of an assessment tool, with indicators of different complexity (NAHGAST Meal-Basic and NAHGAST Meal-Pro), were developed that can be used by kitchen professionals to determine the sustainability performance of their products - the offered meal. An informed selection of indicators, and a discussion of what processes and impacts this indicator relates to in the wider context, are essential and are discussed in this paper. Furthermore, in the selection of indicators for the purpose of our research certain criteria were considered simultaneously: (1) Communicability - What information an indicator can communicate and how comprehensible this information is for different actors; (2) Feasibility and data availability - Whether there is sufficient data for an indicator to be included and whether it is realistic for companies to integrate this indicator in their daily work practice; and (3) Scientific relevance - Whether the indicator is relevant for sustainability efforts on a larger scale and for related discussions in the scientific community. Insights related to these considerations are valuable for future developments in sustainability assessment in out-of-home gastronomy. The tool has been used to evaluate a number of dishes and results are deemed meaningful. However, assessments must not be understood as an accurate measurement but as an approximation of the sustainability of meals. At the level of individual indicators, they allow a detailed analysis and targeted optimization of recipes, while the aggregated results in the form of labels can be communicated well to customers. However, deficiencies and challenges, as discovered in the application phase of the project, demonstrate research gaps in the wider context. Finally, further steps for an integration of the tool in company processes and remaining options for companies to adjust the tool are discussed.

Measure or management? : Resource use indicators for policymakers based on microdata by households
(2018)
Sustainable Development Goal 12 (SDG 12) requires sustainable production and consumption. One indicator named in the SDG for resource use is the (national) material footprint. A method and disaggregated data basis that differentiates the material footprint for production and consumption according to, e.g., sectors, fields of consumption as well as socioeconomic criteria does not yet exist. We present two methods and its results for analyzing resource the consumption of private households based on microdata: (1) an indicator based on representative expenditure data in Germany and (2) an indicator based on survey data from a web tool. By these means, we aim to contribute to monitoring the Sustainable Development Goals, especially the sustainable management and efficient use of natural resources. Indicators based on microdata ensure that indicators can be disaggregated by socioeconomic characteristics like age, sex, income, or geographic location. Results from both methods show a right-skewed distribution of the Material Footprint in Germany and, for instance, an increasing Material Footprint with increasing household income. The methods enable researchers and policymakers to evaluate trends in resource use and to differentiate between lifestyles and along socioeconomic characteristics. This, in turn, would allow us to tailor sustainable consumption policies to household needs and restrictions.
Im Forschungsprojekt "Landscaping" untersuchte das Wuppertal Institut die für Nordrhein-Westfalen aus heutiger Sicht denkbaren Technologieansätze, die dafür nötigen politischen Rahmenbedingungen sowie mögliche Innovationen entlang der Wertschöpfungsketten. Bestandteil des Berichts sind Steckbriefe, in denen die möglichen Technologien für treibhausgasneutrale Industrieprozesse samt offener Forschungsfragen und Infrastrukturbedarfe dargestellt sind. Das Projekt entstand im Auftrag des Ministeriums für Wirtschaft, Innovation, Digitalisierung und Energie des Landes Nordrhein-Westfalen.
Ziel dieses Berichts im Rahmen des Projekts "Erfolgsbedingungen für Systemsprünge und Leitbilder einer Ressourcenleichten Gesellschaft" ist es, eine solche Ressourcenleichte Gesellschaft zu definieren. Hierzu wird zunächst der Rahmen für eine Ressourcenleichte Gesellschaft durch Aufbereitung der relevanten Diskurse bestimmt. Kapitel 1 zeichnet die zeitgeschichtliche Entwicklung des ressourcenbezogenen Nachhaltigkeitsdiskurses von 1972 bis in die Gegenwart nach. Aus dieser Analyse werden relevante Gesichtspunkte für eine Ressourcenleichte Gesellschaft identifiziert und am Ende des Kapitels in einer Übersicht dargestellt. Das zweite Kapitel entwickelt darauf aufbauend den bereits genannten definitorischen Rahmen, d.h. es erfolgt eine grundsätzliche Erarbeitung der normativen Kriterien, die eine solche Gesellschaft ausmachen sollte. Kapitel 3 skizziert dann existierende Zugänge zur Ressourcenleichten Gesellschaft und zeigt wichtige Merkmale dieser Ansätze auf, welche zur Entwicklung der Ressourcenleichten Gesellschaft durch Kontrastierung oder Übernahme von Merkmalen beitragen können.
Since human nutrition is responsible for about 30 % of the global natural resource use and in order to decrease resource use to a level in line with planetary boundaries, Lukas et al. (2016) proposed a re-source use reduction in the nutrition sector by a factor 2 (Material Footprint).
The catering sector needs clearly defined indicators to assess their business activities' impact on ecology, social aspects, economic value, and health status. Within the project NAHGAST two sets of indicators, called NAHGAST Meal-Basis and NAHGAST Meal-Pro were developed. The indicator sets are proposed to measure several, with sustainability-associated challenges, such as such as the ecological, social and economical effects, which may come along with the production and the consumption of a meal. Basically, the NAHGAST Meal-Basis deals with qualitative indicators, such as the amount of organic food per serving or the percentage of food wasted. This set is supposed to enable leaders to assess the sustainability of their meals and to visualize future improvements on a simplistic level. The NAHGAST Meal-Pro deals with a more sophisticated set of indicators, such as the carbon and material footprint or the cost recovery per meal. Both sets are underpinned with sus-tainable targets and elaborated as an Excel-based assessment tool, which is tested within a one-year case study. The usefulness and the limits of the tool, as well as current results of the implementation including pro-posed challenges, are discussed.
Against the background of environmental problems arising from the growing extraction of natural resources and resource depletion, achieving a sustainable development is an indispensable challenge in the twenty-first century. In this article we want to show how socio-technical and product-service innovations can change social practices - the routine doings in everyday life - and, thus, support transition of socio-technical systems. We introduce theoretical considerations on how social practice theories and the framework of the Multi-Level Perspective in transition research can be linked to better understand transition processes from a micro-macro-link perspective. We then present cases based on desk research in the field of practices in bathing, heating and nutrition to show how these have changed over the past decades. Building on this, examples of concepts for sustainable product-service-design in these areas are introduced as leverage points to change social practices in everyday life. These have been developed in research projects or design student seminar works, respectively. We argue that this implies sustainable product-service-systems should be developed in a user- and actor-integrated framework, such as Sustainable LivingLabs. The integration of users and other stakeholders into participatory co-creation processes enables tailored solutions that take actual routines and dependencies seriously into account.
A continuing trend of global urbanization leads to a geographical concentration of population and social activities that causes a regional compression of concomitant resource and energy consumption. This paper argues that a Sustainable Living Lab infrastructure (SusLab) in urban areas facilitates a systematic integration of user's consideration in the design and development of Product-Service Systems (PSS) that enables changes of daily routines in favor of urban wealth development and conservation of ecosystem services. The authors build on the Sustainable Consumption and Production (SCP) Model of the Wuppertal Institute that provides a theoretical framework of sociotechnical rearrangements towards urban sustainability transition. Therefore, a reconfiguration of social practices and PSS in a desired direction according to social, ecological and economic concerns is reconsidered on the micro level in line with efficiency, consistency, and sufficiency strategies. The authors introduce an assessment framework for urban sustainable development and illustrate multifarious concepts of PSS that are aiming to decouple wealth development from resource and energy consumption in urban areas.
The transformation processes towards a sustainable development are complex. How can science contribute towards new solutions and ideas leading to change in practice? The authors of this book discuss these questions along the energy transition in the building sector.
A transformative research that leaves the neutral observer position needs appropriate concepts and methods: how can knowledge from different disciplines and from practice be integrated in order to be able to explain and understand complex circumstances and interrelations? What role do complex (agent-based) models and experiments play in this respect? Which mix of methods is required in transformative science in order to actively support the actors in transformation processes?
Theses questions are illustrated by the example of the BMBF funded project "EnerTransRuhr".
Das Ziel der Studie erschließt sich aus der Idee, eine Übersicht über den Stand der Erkenntnisse in den Bereichen Ressourcenkonsum (t) und Ausgaben (€) sowie Zeitverwendung (h) mit Bezug auf Typologien (Wohnen, Mobilität, Ernährung) zu erhalten. Darauf basierend wurden Transitionlandkarten entwickelt, die eine offene Erschließung von Pfadveränderungen und Lösungswegen für nachhaltigere Konsumentscheidungen und Lebensstilveränderungen ermöglichen.
Die Sustainable Development Goals (SDGs) schlagen zur Indikation verantwortungsvoller Konsum- und Produktionsstrukturen bzw. zum nachhaltigen Management und der effizienten Nutzung natürlicher Ressourcen den Material Footprint pro Kopf vor. Zudem sollen SDG-Indikatoren prinzipiell in der Lage sein, zwischen verschiedenen Bevölkerungsgruppen (etwa nach Einkommen oder Alter) unterscheiden zu können. Wir stellen einen Indikator aus der Nachhaltigkeitsstrategie NRW zum Ressourcenverbrauch des privaten Konsums auf der Grundlage von Mikrodaten vor. Der größte Ressourcenverbrauch der privaten Haushalte in NRW bleibt Wohnung, Nahrungsmittel und Verkehr vorbehalten. Dabei ist zwischen 2003 und 2013 die größte Steigerung des Ressourcenverbrauchs in Post und Telekommunikation zu verzeichnen, wobei sich insgesamt der Ressourcenverbrauch leicht reduziert hat. Der Indikator zum Ressourcenverbrauch der privaten Haushalte erfüllt die Anforderungen an Indikatoren der Sustainable Development Goals sowie der Nachhaltigkeitsstrategie des Landes NRW. Gleichzeitig empfehlen wir eine weitere Disaggregierung des Material Footprints nicht nur nach Bevölkerungsgruppen, sondern auch in Gütergruppen auf der Basis von Lebenszyklusanalysen.
We present the results of a regression analysis of a large-scale integrated user online application that surveys natural resource use and subjective well-being in Germany. We analyse more than 44,000 users who provided information on their natural resource consumption (material footprint) as well as their personal socio-economic and socio-psychological characteristics. We determine an average material footprint of 26 tonnes per person per year. In addition, we endeavour to determine how much environment humans need by regressing natural resource use as well as relevant socio-economic and socio-psychological features on subjective well-being. We establish a slightly negative correlation between subjective well-being and material footprints. A higher material footprint is associated with lower subjective well-being. We conclude that consumer policies seeking to promote sustainable behaviour should highlight the fact that a lower material footprint may result in greater subjective well-being.
The field of nutrition will face numerous challenges in coming decades; these arise from changing lifestyles and global consumption patterns accompanied by a high use of resources. Against this background, this paper presents a newly designed tool to decrease the effect on nutrition, the so-called Nutritional Footprint. The tool is based on implementing the concept of a sustainable diet in decision-making processes, and supporting a resource-light society. The concept integrates four indicators in each of the two nutrition-related fields of health and environment, and condenses them into an easily communicable result, which limits its results to one effect level. Applied to eight lunch meals, the methodology and its calculations procedures are presented in detail. The results underline the general scientific view of food products; animal-protein based meals are more relevant considering their health and environmental effects. The concept seems useful for consumers to evaluate their own choices, and companies to expand their internal data, their benchmarking processes, or their external communication performance. Methodological shortcomings and the interpretation of results are discussed, and the conclusion shows the tools' potential for shaping transition processes, and for the reduction of natural resource use by supporting food suppliers' and consumers' decisions and choice.
Das Thema dieses Papieres ist die Integration von Nachhaltigkeitskriterien in den Innovationsprozess von Living Labs. Es wurde ein Bewertungsmodell entwickelt, welches den Innovationsprozess in Living Labs zu strukturieren hilft, indem die Anforderungen und Bewertungskriterien definiert werden, die den Innovationsprozess unter dem Nachhaltigkeitsvorzeichen leiten können. Das Modell "Bewertung von Nachhaltigkeitswirkungen im Living Lab Innovationsprozess" stellt den Innovationsprozesses in Living Labs dar und hilft dabei, konzeptionell Nachhaltigkeitskriterien auf Grundlage verschiedener Anforderungsgruppen abzuleiten.
Dieses Papier ist ein Ergebnis aus dem Arbeitspaket 2 "Operationalisierung" im Rahmen des Projektes "Living Labs in der Green Economy: Realweltliche Innovationsräume für Nutzerintegration und Nachhaltigkeit" (INNOLAB), das im Rahmen der Sozial-ökologischen Forschung zum Themenschwerpunkt "Nachhaltiges Wirtschaften" vom Bundesforschungsministerium gefördert wird.
Die Transformationsprozesse hin zu einer nachhaltigen Entwicklung sind komplex.
Wie kann Wissenschaft dazu beitragen, dass neue Lösungen und Ideen in der Praxis zu Veränderung führen? Dieser Frage gehen die Autorinnen und Autoren am Beispiel der Gebäudeenergiewende nach. Eine transformative Forschung, die den neutralen Beobachterposten verlässt, braucht entsprechende Konzepte und Methoden: Wie kann Wissen aus unterschiedlichen Disziplinen und aus der Praxis integriert werden, um komplexe Sachverhalte und Zusammenhänge zu erklären und zu verstehen? Welche Rolle spielen komplexe (agentenbasierte) Modelle und Experimente dabei? Wie sieht der Methodenmix einer transformativen Wissenschaft aus, die Akteure bei Transformationsprozessen aktiv unterstützt? Illustriert werden diese Fragen am Beispiel des vom BMBF geförderten Forschungsprojektes "EnerTransRuhr".
Human nutrition is responsible for about 30% of the global natural resource use. In order to decrease resource use to a level in line with planetary boundaries, a resource use reduction in the nutrition sector by a factor 2 is suggested. A large untapped potential to increase resource efficiency and improve consumers' health status is assumed, but valid indicators and general guidelines to assess these impacts and limits can barely be found. Therefore we will have a try to define sustainable limits towards the individuals' daily diet and therefore stimulate current available scientific debate.
Within the paper an examination of existing indicators and assessment methods is carried out. We set the focus on health indicators, such as energy intake, and environmental indicators, such as the carbon or material footprint. The paper aims to provide first, an assessment of core indicators to explore the sustainability impact of foodstuff, and second, a deeper understanding and a discussion of sustainable limits for those dimensions of food and nutrition. Therefore we will discuss several ecological and health indicators which may be suitable to assess the sustainabilty impact and indicate differences or similarities. As a result it becomes obvious that several ecological indicators "point in the same direction" and therefore a discussion about the variability and the variety of these indicators has to be faced in the future. Further the definition of sustainable levels per indicator is an essential aspect to get an idea about the needed barriers for a sustainable nutrition, by now first steps had been made, but no binding guidelines are available yet. Therefore the paper suggests a few indications to set up sustainable levels for health and environmental indicators, based on the idea to reduce the resource use level up to 30-50% in 2030.
Ressourcenleichte Utopien
(2016)
In order to make our lifestyles sustainable, changing our consumption patterns is fundamental. Hence, we need to better understand who the "consumers" are and to consider them as an active actor to directly engage for ensuring effective policies. In order to support a resource-light society, production and consumption need to be considered through an integrated system view; within this, consumers play an important role as co-acting subjects. Almost every activity in private life involves a form of consumption aimed at satisfying the subject's needs and often regarded through an economic lens. Sustainable development is not about abolishing private consumption, but rather about making it environmentally, socially and individually sustainable in its design, organization and realization, also involving ideas of simplicity or renunciation. In this paper, we will assess the status quo of the German and European debates on Consumer Research Policies and discuss the idea to link sustainability research and consumer research - where a strategic relation is currently missing. Within that discussion, an evidence-based and obligatory consumer research strategy in Germany and Europe would represent a significant improvement. A system view perspective is necessary to take into consideration the impressive amount of diversity, and to elaborate realistic economic and consumer policies. Therefore, we propose nine steps for understanding the role of the consumer in implementing sustainable development from a scientific and political perspective. The limitations of this paper are thus a result of the very diverse and often unclear policies and agendas produced by governments. The implementation of the proposed innovative research agenda for a future-orientated and sustainability-based consumer research is not free from challenges. Still, the paper suggests the first steps towards this direction. After a critical discussion of the current EU and German consumer and sustainability policies, nine differentiated and substantial ways to integrate and ameliorate them are proposed.
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.
Social innovations, which transform resource intensive routines and practices into low-resource ones, combined with socio-technically designed transition paths, which are created around sustainability and environmental criteria, are milestones for implementation and diffusion of SCP (Sustainable Consumption and Production). This paper analyses such processes based on eight key components in order to evaluate and explain transformation and transition towards a sustainable lifestyle. Actors on all levels of society are included in this approach, creating a whole framework. Global megatrends, such as climate change, demographic change or resource scarcity will be put into relation with current policies and production trends, which play an important role for the development of transition pathways and future scenarios. This will enable us to work out guidelines and ideas on how to create a more sustainable society specifically.
The innovative software system "myEcoCost" enables to gather and communicate resource and environmental data for products and services in global value chains. The system has been developed in the consortium of the European research project myEcoCost and forms a basis of a new, highly automated environmental accounting system für companies and consumers. The prototype of the system, linked to financial accounting of companies, was developed and tested in close collaboration with large and small companies.
This brochure gives a brief introduction to the vision linked to myEcoCost: a network formed by collaborative environmental accounting nodes collecting environmental data at each step in a product's value chains. It shows why better life cycle data are needed and how myEcoCost addresses and solves this problem. Furthermore, it presents options for a future upscaling of highly automated environmenal accounting for prodcuts and services.
A key challenge of the 21st century is to transform society into one that features sustainable patterns of production and consumption. To achieve this, transition processes need to be designed in key areas such as housing, mobility and nutrition. The design and large-scale implementation of sustainable product service systems (PSS) is regarded a promising approach for sustainability transitions. Real-life socio-technical experiments are an important infrastructure for designing PSS in collaboration with stakeholders and users. In this paper, we argue that transdisciplinary and action research methods are required for institutionalising an experimental set-up and developing PSS within such infrastructures. We present the Sustainable LivingLabs (SLL) research infrastructure and its methodology as an example of such experimental settings. It was collaboratively developed with key stakeholders in three consecutive research projects and applied to e.g. heating and space heating. We show new qualities of SLL in relation to existing LivingLabs and approaches for PSS design and present its methodological three-phase model (insight research, prototyping, field testing) of research. Our article contributes to knowledge on a methodological framework and tool-kit for PSS development in SLL with a clear focus on socio-ecological sustainability. Intermediate findings confirm the high influence of user practices on heating energy consumption and show starting points for PSS development: e.g. transformational products, home-automation combined with consulting along value chains. We hypothesise that developing PSS in user- and stakeholder-integrated settings supports acceptance and diffusion and, by taking into account users' social practices of utilising novelties, reduces rebound effects caused by incorrect application.
The food and agricultural sector will face numerous challenges in the next decades, arising from changing global production and consumption patterns, which currently go along with high resource use, causing ecological and socio-economic impacts. The aim of this paper is to illustrate and evaluate the practical applicability of the Hot Spot Analysis methodology in the context of supply chain management in companies. The HSA is a method to identify social and ecological problems along the entire life cycle of a product. Special emphasis is put on a customized implementation in the value chain beef of McDonald's Germany. The HSA of McDonald's beef value chain shows that the main ecological problems arise in the phase of raw material extraction, whereas the main social problems can be identified in the phase of slaughtering. Finally, the paper shows potentials and shortcomings of such a customized application and how the results can be implemented in the sustainability management of a company.
Although there are already some qualification offers available for enterprises to support resource efficiency innovations, the high potentials that can be identified especially for small and medium sized enterprises (SMEs) have not been activated until now. As successful change lies in the hands of humans, the main aim of vocational education has to be the promotion of organisational and cultural changes in the enterprises. As there is already a small but increasing number of enterprises that perform very well in resource efficiency innovations one question arises: What are typical characteristics of those enterprises? Leaning on a good-practice approach, the project "ResourceCulture" is going to prove or falsify the hypothesis that enterprises being successful with resource efficiency innovations have a specific culture of trust, which substantially contributes to innovation processes, or even initially enables them. Detailed empirical field research will light up which correlations between resource efficiency, innovation and cultures of trust can be found and will offer important aspects for the improvement of management instruments and qualification concepts for workplace training. The project seizes qualification needs that were likewise mentioned by enterprises and consultants, regarding the implementation of resource efficiency. This article - based on first empirical field research results - derives preliminary indications for the design of the qualification module for the target groups resource efficiency consultants and managers. On this basis and in order to implement "ResourceCulture" conceptual and methodological starting points for workplace training are outlined.
It is widely accepted that environmental awareness is essential, yet does not inevitably lead to responsible use of resources. Additional factors on the individual level include the meaning constructed by the term "resources" and the individual and social norms that influence the relevant behavior. Current didactic concepts do not take into account such aspects. Therefore, this article uses a didactic-psychological approach for designing an educational concept for raising awareness for a responsible use of natural resources. Combining insights of environmental psychology and of constructivist didactics, a general principal of "norm-oriented interpretation learning" is outlined to enrich the didactic debate on responsible and efficient resource use. Based on the presentation of a qualifying module for resource efficiency consultants as a practical example of resource education, a new didactical approach, namely "open-didactic exploration" (short form: ODE) is introduced. The article discusses the theory-based elements of ODE and illustrates a step by step process for designing educational materials. This adds to the theoretical debate about a didactic design for resource oriented education. Furthermore, this method can be directly used by practitioners developing education and training material (e.g., teachers, trainers in vocational education). The Wuppertal Institute developed and applied this method in numerous projects. The conclusion and outlook discusses future expectations and scope of the introduced ODE method as a contribution to foster "norm-oriented interpretation learning", suggesting perspectives for further development.
Einweg ist kein Weg : ressourceneffizient verpackt ; wieviel Umwelt brauchen Mineralwasserflaschen?

The concept Material Input per Service Unit (MIPS) was developed 20 years ago as a measure for the overall natural resource use of products and services. The material intensity analysis is used to calculate the material footprint of any economic activities in production and consumption. Environmental assessment has developed extensive databases for life cycle inventories, which can additionally be adopted for material intensity analysis. Based on practical experience in measuring material footprints on the micro level, this paper presents the current state of research and methodology development: it shows the international discussions on the importance of accounting methodologies to measure progress in resource efficiency. The MIPS approach is presented and its micro level application for assessing value chains, supporting business management, and operationalizing sustainability strategies is discussed. Linkages to output-oriented Life Cycle Assessment as well as to Material Flow Analysis (MFA) at the macro level are pointed out. Finally we come to the conclusion that the MIPS approach provides relevant knowledge on resource and energy input at the micro level for fact-based decision-making in science, policy, business, and consumption.
The paper suggests a sustainable material footprint of eight tons, per person, in a year as a resource cap target for household consumption in Finland. This means an 80% (factor 5) reduction from the present Finnish average. The material footprint is used as a synonym to the Total Material Requirement (TMR) calculated for products and activities. The paper suggests how to allocate the sustainable material footprint to different consumption components on the basis of earlier household studies, as well as other studies, on the material intensity of products, services, and infrastructures. It analyzes requirements, opportunities, and challenges for future developments in technology and lifestyle, also taking into account that future lifestyles are supposed to show a high degree of diversity. The targets and approaches are discussed for the consumption components of nutrition, housing, household goods, mobility, leisure activities, and other purposes. The paper states that a sustainable level of natural resource use by households is achievable and it can be roughly allocated to different consumption components in order to illustrate the need for a change in lifestyles. While the absolute material footprint of all the consumption components will have to decrease, the relative share of nutrition, the most basic human need, in the total material footprint is expected to rise, whereas much smaller shares than at present are proposed for housing and especially mobility. For reducing material resource use to the sustainable level suggested, both social innovations, and technological developments are required.
Living Labs for Sustainable Development aim to integrate users and actors for the successful generation of low-resource innovations in production-consumption systems. This paper investigates potentials of and measures towards the realization of a German Living Lab infrastructure to support actor-integrated sustainability research and innovations in Germany. Information was primarily derived from extensive dialog with experts from the fields of innovation, sustainable development and the Living Lab community (operators, users, etc.), which was facilitated through interviews and workshops. A status quo analysis revealed that, generally, the sustainability and Living Lab communities are hardly intertwined. Twelve Living Labs that explicitly consider sustainability aspects were identified. The application fields "Living and Working", "Town, Region and Mobility", and “Retail and Gastronomy" were identified as particularly suitable for investigation in Living Labs and highly relevant in terms of resource efficiency. Based on the analyses of drivers and barriers and SWOT, keystones for the development of a research infrastructure for user integrated development of sustainable products and services were formulated. Suggested strategies and measures include targeted funding programs for actor-integrated, socio-technical research based on a Living Lab network, a communication campaign, and programs to foster networking and the inclusion of SMEs.
Alltagsorientierte Lösungsansätze zur Wissensvermittlung und zur Etablierung des suffizienten Konsums werden nur sehr selten in den Konsumalltag der Verbraucherinnen und Verbraucher etabliert. Denn bis heute fokussieren Bildungs- und Forschungsansätze vorrangig die Appelle an Effizienz und Konsistenz im Kontext der nachhaltigen Entwicklung. Der vorliegende Beitrag zeigt, welche Strategien sich im Kontext des suffizienten Handelns im Alltag anwenden lassen und welche Potentiale sich für verschiedene Verbrauchergruppen eröffnen. Zur Implementierung suffizienter Handlungsweisen ist die Integration neuer sozialer Praktiken bzw. das Ausbrechen aus alten Routinen notwendig. Der Beitrag offenbart, dass heute rudimentäre Handlungsempfehlungen zum suffizienten Handeln im Alltag vorhanden sind, die bereits bewusst oder unbewusst praktiziert werden, doch bislang ohne System, und nicht gefördert durch Beratungsinstrumente der Verbraucherbildung. Beratungsinstrumente, die die Verbraucherinnen und Verbraucher aktiv ansprechen sind dauerhaft zu integrieren. Weiterführend sind Forschungsaktivitäten notwendig, um Konsumprofile der Verbraucherinnen und Verbraucher besser abzubilden und passgenaue, alltagsorientierte Maßnahmen zu entwickeln.
There are a variety of economic and ecological benefits to increased resource efficiency. Social, institutional and technical innovations can all contribute towards efficiency increases. Companies face different hurdles in fostering such innovation. Small and medium-sized companies are subject to specific constraints that may prevent them from benefiting from innovation-induced resource efficiency improvements. Qualitative interviews were conducted among German small and medium-sized enterprises (SMEs) and intermediaries to identify barriers for resource efficiency innovations and to elaborate a policy mix at the federal level that could help SMEs to overcome these. We found five major barriers to resource efficiency innovations in German SMEs, comprising deficits in innovation culture, inter-firm cooperation along the value chain, finance, awareness and take-up of government funds. We propose a distinct policy mix as a response to this situation. The policy mix comprises the interlocking and synergistic elements of government funding schemes, innovation agents and innovation laboratories.
Aufgrund seiner starken Umweltauswirkungen gilt der Lebensmittelsektor durch Effekte in Produktion, Verarbeitung, Konsum und Entsorgung gemeinhin als ein wichtiges Handlungsfeld, soll eine gesellschaftliche Transformation in Richtung Nachhaltigkeit weiter vorangetrieben werden. Da Ernährungsgewohnheiten sowohl ökologische Auswirkungen induzieren als auch gesundheitliche Folgen für die Verbraucher haben, sind Konzepte gefragt, die ökologische mit gesundheitlichen Indikatoren kombinieren; diese sind jedoch bislang rar. Das vorgestellte Instrument des Nutritional Footprint greift diese Problemstellung auf und verbindet in einem innovativen Konzept jeweils vier Kernindikatoren beider Dimensionen. Mithilfe des Konzepts erhalten Verbraucher einen Überblick zu Umwelt- und Gesundheitswirkungen ihrer Ernährung. Unternehmen können wiederum interne Datensätze verwalten, Benchmarking betreiben und ihre externe Kommunikationsleistung erweitern.
SustChange-Agents - Personen, die im organisationalen Bereich Veränderungen hin zu einer nachhaltigeren Entwicklung voran bringen wollen - benötigen personale, soziale, kognitiv-methodische und sachlich-fachliche Kompetenzen. Dies hat eine qualitative Inhaltsanalyse ausgewählter Kompetenzsystematiken aus den Bereichen "Change Management" (Wandel in Organisationen), berufliche Bildung, Bildung für nachhaltige Entwicklung und Berufsbildung für nachhaltige Entwicklung gezeigt. Den personalen Kompetenzen fällt dabei eine besondere Bedeutung zu, da sie ebenfalls Persönlichkeitseigenschaften einschließen. Es konnte gezeigt werden, dass die allgemein diskutierten Kompetenzsystematiken implizit Aspekte jener Kompetenzen aufweisen, die im Kontext von Nachhaltigkeit angeführt werden - Nachhaltigkeit ist also auf Kompetenzebene an die Konzeptionen von Wandel und beruflicher Bildung anschlussfähig.
Our perception of design is changing, for design today is no longer concerned only with aesthetics. Now the key factors are interdisciplinary competence and approaches to problem solving. Both politicians as well as businesses recognise design's hybridity and increasingly implement it as a driver of sustainable development (see Chap. 2: Design as a Key Management Factor for Sustainability).
But what exactly does "sustainability" mean? What does it mean in this specific context? People must make use of natural resources to meet their basic needs. In this process, resources are transferred into commercial circulation and usually transformed into products with a particular function. Yet the environment is limited and humanity uses more resources than the Earth can sustainably provide. It is time to rethink and generate the same usage while consuming fewer resources (see Chap. 3: Environmental Space - Challenging Transitions).
Most countries have incorporated sustainability strategies into their political agendas in order to counteract the threats of climate change caused by the overuse of natural resources, high CO2 emissions, and other factors. The indicators for these strategies vary greatly from country to country (see Chap. 4: Sustainability - Challenges, Politics, Indicators).
These indicators need to be taken into account if we are to successfully implement a product or service within a specific context. A concept can only be successful when country-specific indicators are taken into account and the societal context is incorporated into the plan right from the start. The goal is to develop services that support national sustainability targets in production and consumption systems (see Chap. 5: Managing Sustainable Development).
When it comes to companies, these changes can simply be introduced in the form of services or products. In the end, it is the users who decide on the success or failure of innovative solutions by either integrating them into their daily lives or ignoring them. Solutions will only be integrated into users' lives when their role within the social framework remains unchallenged by behavioural transformations caused by use of the solution. In order for users to be able to adopt innovations, sustainable development must take place simultaneously on many different levels. These multi-levelled transitions allow for the transformation of society as a whole. Designers can act as agents of change by providing the needed innovations (see Chap. 6: Transition Requires Change Agents for Sustainability).
If we are to develop suitable solutions and new approaches, the real needs have to be analysed at the beginning of the development process. New physical products, which frequently result in auxiliary products, are often developed without taking into account the overall context, whereas the development of service-orientated solutions is ignored. A physical product is not absolutely necessary. A service (which is naturally dependent on physical products) can usually fulfil the need just as well - or perhaps even better and at a lower cost – while using fewer or no resources (see Chap. 7: Needs & Services - An Approach). There are a variety of possible approaches to integrate sustainability into the design process (see Chap. 8: Design Process).
Precisely which solution is "most or more sustainable" (this is dependent on the defined targets and the indicators used) is often not immediately obvious, and we must turn to a set of methods for a transparent and tangible assessment (see Chap. 9: Sustainability Assessment in Design - Overview and Integration of Methods).
Die Studie untersucht das Potential der deutschen Forschungslandschaft für nutzerintegrierende Produkt- und Dienstleistungsinnovationen. Sie zeigt auf, dass Living Labs mit zunehmender Mensch-Technik-Interaktion eine wichtige Rolle für nachhaltige Entwicklung spielen können. Living Labs zielen auf eine frühzeitige Integration von Nutzerbedürfnissen und des Anwendungskontextes in Forschungs- und Innovationsprozesse. Sie können beispielsweise Lösungen zur Erhöhung der Akzeptanz ressourcenschonender Systemlösungen oder zur Vermeidung von negativen systemischen Auswirkungen auf den Ressourcen- und Energieverbrauch bieten.
In der Potentialstudie werden Anwendungsfelder von Living Labs identifiziert sowie Aspekte, die für die Entwicklung des Forschungs- und Innovationssystems relevant sind, untersucht. Weiterhin werden Handlungsoptionen zur Förderung transdisziplinärer Verbundprojekte und zu strukturbildenden Maßnahmen aufgezeigt. Die Studie basiert auf den Ergebnissen des Projekts "Nachhaltigkeitsinnovationen im Living Lab", welches vom Bundesministerium für Bildung und Forschung (BMBF) gefördert wurde, und ist am Wuppertal Institut in Zusammenarbeit mit dem Fraunhofer-Institut für Arbeitswirtschaft und Organisation (IAO), dem Fraunhofer-Institut für System- und Innovationsforschung (ISI) sowie dem Faktor 10-Institut entstanden ist.
The article argues for a need to overcome a conventional notion of product design. In this regard, the article offers an integrative and systemic approach to sustainable design. Instead of focusing on objects, a user-centred perspective is adopted. A sustainable design of products and services requires the integration of production-orientated (efficiency and consistency) and consumption-orientated (sufficiency) strategies. The article introduces the concept of an indicator that is capable of comprehending a lifecycle-wide analysis of products and that favours the integration of existing sustainability strategies. The goal is not to design sustainable products but rather to design systems that manage to foster sustainable lifestyles. The article illustrates the usability of the introduced concept by showing examples of strategic integrative thinking in sustainable design from the Sustainable Summer Schools.
Das dematerialisierte Design

This paper argues that the contemporary growth paradigm needs to be reconsidered on a micro level of consumption and product service-systems. This becomes necessary since a dynamic link between macro strategies and micro implementation of sustainable growth is missing up to date. Therefore, mainstream sustainability strategies of efficiency and consistency are extended by sufficiency in order to integrate strategies for individual welfare within their social environment. Limits to and drivers for growth are revised and updated socially in terms of qualitative values, diminishing marginal utility or symbolic social distinction. We elaborate a definition of sustainable growth that fosters individual welfare by enhancing social enactment within the boundaries of environmental space. Shifting focus on social aspects in design fosters more sustainable production and consumption patterns while sustaining individual welfare. We derive latent indications for eco-intelligent product service-arrangements and evaluate to concepts by referring to introduced definitions and according indications. With doing so, we illustrate new pathways for the translation of sustainable growth and strategies into product service-systems.
