Description: 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.

Description: Science and education are central fields and a lever for sustainable development. With the newly developed student teaching and learning format "Transformative Innovation Lab" - TIL for short - students are to be enabled to conduct independent transformative research. To this end, the researchers, under the direction of the Wuppertal Institute, developed and tested the new learning concept in the project "Development, testing and dissemination of new qualification offers for 'change agents' for transformative learning using the real-world laboratory approach" (EEVA). The detailed results and numerous implementation tips have been published in a practical handbook aimed at academic teaching staff and other multipliers.

Description: In this paper the results of an analysis of the material intensity of advanced composite materials are presented. The analysis is based on the MIPS-concept of the Wuppertal Institute which allows the calculation of the overall material intensity of products and services. It can be shown that the production of one kg of E-Glass fibers is connected with the consumption of 6.2 kg materials, 95 kg water and 2.1 kg oxygen which is of similar size compared to the inputs required in steel production. Material inputs required to produce one kg of p-aramid are 37 kg of materials and 19.6 kg air. Values for carbon fibers are even higher yielding to 61.1 kg of abiotic materials and 33.1 kg of air. Similarly, the production of epoxy resins is connected with larger material flows than the production of polyester resins. Of core materials, inputs per kg for PVCfoam exceed those in PUR-foam production by a factor of 1.4 in water to 2.3 in abiotic material consumption. However, ecologically decisive are not the inputs per kg but the material input per service unit. Therefore, the material input per service unit computed for the body of a passenger ship and a robot arm are compared with alternative steel and aluminium versions. Both examples show that in the case of significant inputs during the user phase of products, even a more material intensive investment in the production phase can yield significant ecological benefits over the whole life-cycle compared to metal versions. Improvements can easily reach a factor of two albeit significant potential for engine optimizations have still been neglected. Results already include the actual recycling quota of metals whereas for composites only virgin material has been calculated as any form of real recycling does not actually exist but only certain types of downrecycling. Of those treatment options, first material recycling and second the use in blast furnaces would lead to better results in resource productivity than incineration and landfills. The paper finally draws some conclusions about the potential advantages of material substitution in the automotive industry. Due to the rather short real operation time of cars during their user phase - around six months - an investment in advanced composite materials in car production only results in a significant improvement of the overall eco-efficiency of cars if it allows a substantial weight reduction of the overall vehicle.

Description: In order to channel and align the efforts within the COREF project, the Registry of Research Data Repositories – re3data is revising its conceptual service model according to the most important use cases of the various stakeholders working with re3data. Adopting and reflecting current developments in the research data landscape, the update of the service architecture in COREF is based on a bottom-up approach that addresses the results from a stakeholder survey and a stakeholder workshop in November 2020. The findings from the survey and workshop sessions presented in this report informed the development of a Conceptual Model for User Stories, which embeds the registry within the research community and the infrastructure landscape to meet the emerging needs for a trusted repository reference.

Description: Wissenschaft und Bildung sind zentrale Felder und ein Hebel für eine nachhaltige Entwicklung. Mit dem neu entwickelten studentischen Lehr- und Lernformat "Transformative Innovation Lab" - kurz TIL - sollen Studierende dazu befähigt werden, selbstständig transformativ zu forschen. Dazu entwickelten und testeten die Forschenden unter Leitung des Wuppertal Instituts im Projekt "Entwicklung, Erprobung und Verbreitung neuer Qualifizierungsangebote für "Change Agents" zu transformativem Lernen am Beispiel Reallabore" (EEVA) das neue Lernkonzept. Die detaillierten Ergebnisse und zahlreiche Tipps zur Umsetzung haben die Projektbeteiligten in dem vorliegenden Praxis-Handbuch zusammengefasst, das sich an Lehrpersonen sowie weitere Multiplikatorinnen und Multiplikatoren richtet.

Description: An der Schwelle zum 21. Jahrhundert steht die Umweltpolitik in Europa vor großen Herausforderungen. Es gilt den hohen Anspruch des Amsterdamer Vertrages umzusetzen, der eine Integration von Umwelt-, Wirtschafts- und Sozialpolitik vorsieht. Wenn dies der Umweltpolitik in Europa bis zur Jahrtausendwende gelingt, wird sie sich somit zu einer Politik der Nachhaltigkeit weiterentwickeln. Andernfalls droht Umweltpolitik wieder in den Status einer zweitrangigen Sektorpolitik zurückzufallen. In dieser Studie wird versucht, dieser drohenden Entwicklung entgegenzutreten. Ausgehend von einer Beschreibung der Ausgangslage der Umweltpolitik in der Europäischen Union (Kap. 2) werden anschließend mögliche Ziele einer weiterentwickelten Umwelt- bzw. Nachhaltigkeitspolitik erörtert. Eine besondere Bedeutung kommt hierbei den Indikatoren zu, anhand derer die Erreichung von Nachhaltigkeit gemessen werden kann (Kap. 3). In der Folge werden Bedingungen und Möglichkeiten einer Umsetzung ökologischer Ziele auf europäischer Ebene geprüft. Zu diesem Zweck werden zunächst die Wirkungen ökologischer Strategien auf ökonomische und soziale Systeme umrissen; danach werden einige mögliche Maßnahmen und Prioritäten für die Ressorts vorgeschlagen, in denen laut Beschluß der Europäischen Räte von Cardiff und Wien die Integration vorrangig umgesetzt werden soll (Kap. 4). Schließlich werden dem Europäischen Rat in Helsinki strategische Ziele vorgeschlagen und ein Formulierungsvorschlag für die Schlußfolgerungen der finnischen Präsidentschaft gemacht (Kap. 5), um so die Integration von Umweltbelangen in dem Sinne voranzubringen, der in den Kapiteln 3 und 4 beschrieben wird.
