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.
This paper presents the educational program "Encouraging Sustainability", initiated and realized by the "Foundation Forum für Verantwortung", the "ASKO EUROPA-FOUNDATION", and the "Europäische Akademie Otzenhausen/European Academy Otzenhausen" in cooperation with the Wuppertal Institute for Climate, Environment and Energy. The goal is to intensify the public discourse on sustainability within civil society concerning options of sustainable consumption and production patterns. The innovative program consists of two parts: (1) Twelve Books About the Future of the Earth (see section 2), (2) six didactical modules (section 3): From Knowledge to Action. The educational modules focus on important topics and key issues discussed in the context of sustainability: climate change, resource use, energy efficiency, population growth, water use, securing future food supplies, biodiversity etc. The didactical materials are developed as “open learning scenarios: all materials can be linked to many communication forms and situations in a flexible manner. For the creation and realisation of the educational materials the authors have chosen the concept of Sinus-Milieus, developed by Sinus Sociovision, in order to address specific target groups (section 4). The main target groups in the program "Encouraging Sustainability" are "leading groups of society" and multipliers because of their high resource and energy consumption on the one hand and because of their skills and educational background on the other hand. In the last section of this paper (section 5) the first experiences from the implementation of the modules are presented. The authors emphasize that the broad and flexible approach chosen, should work effectively in a period in which green issues rank high in the public opinion worldwide.
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.

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.
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.
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.
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.
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.
Die Ausarbeitung eines Konzepts für Nachhaltigkeitsbildung, welches das Ziel hat, nachhaltige Lebensstile zu befördern, muss zwei Barrieren überwinden können: die eine vom Nichtwissen zum Wissen, die andere vom Wissen zum Handeln. Sie zu überwinden, haben sich u. a. zwei Forschungsstränge zum Ziel gesetzt: Die pädagogische Kompetenzforschung, welche die für eine nachhaltige Denk- und Handlungsweise notwendigen Fähigkeiten aufdeckt, und die umweltpsychologische Theorieentwicklung, welche das Zusammenspiel von Umweltbewusstsein und andere auf das Umwelthandeln einwirkende Faktoren fokussiert. Die "Forschungsgruppe Nachhaltiges Produzieren und Konsumieren" des Wuppertal Instituts hat durch den Versuch, beide Stränge zu integrieren, ein eigenes Bildungs- und Kommunikationskonzept zur Förderung nachhaltiger Denk- und Handlungsweisen entwickelt und in die praktische Bildungsarbeit übersetzt. Die Theorie und Praxis dieses Bildungskonzepts sollen hier vorgestellt werden.
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.
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.
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 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.
