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: Background: Facing planetary boundaries, we need a sustainable energy system providing its life support function for society in the long-term within environmental limits. Since science plays an important role in decision-making, this study examines the thematic landscape of research on sustainable energy, which may contribute to a sustainability transformation. Understanding the structure of the research field allows for critical reflections and the identification of blind spots for advancing this field. Methods: The study applies a text mining approach on 26533 Scopus-indexed abstracts published from 1990 to 2016 based on a latent Dirichlet allocation topic model. Models with up 1100 topics were created. Based on coherence scores and manual inspection, the model with 300 topics was selected. These statistical methods served for highlighting timely topic trends, differing thematic fields, and emerging communities in the topic network. The study critically reflects the quantitative results from a sustainability perspective. Results: The study identifies a focus on establishing and optimizing the energy infrastructure towards 100% renewable energies through key modern technology areas: materials science, (biological) process engineering, and (digital) monitoring and control systems. Energy storage, photonic materials, nanomaterials, or biofuels belong to the topics with the strongest trends. The study identifies decreasing trends for general aspects regarding sustainable development and related economic, environmental, and political issues. Conclusions: The discourse is latently adopting a technology-oriented paradigm focusing on renewable energy generation and is moving away from the multi-faceted concept of sustainability. The field has the potential to contribute to climate change mitigation by optimizing renewable energy systems. However, given the complexity of these systems, horizontal integration of the various valuable vertical research strands is required. Furthermore, the holistic ecological perspective considering the global scale that has originally motivated research on sustainable energy might be re-strengthened, e.g., by an integrated energy and materials perspective. Beyond considering the physical dimensions of energy systems, existing links from the currently technology-oriented discourse to the social sciences might be strengthened. For establishing sustainable energy systems, future research will not only have to target the technical energy infrastructure but put a stronger focus on issues perceivable from a holistic second-order perspective.

Description: At the heart of transition research lies the question of how to "scale up" sustainable alternatives from a protected niche to the creation of mainstream practices. While upscaling processes are often seen as an essential element that contributes to societal transformation, upscaling itself remains a fuzzy concept. We argue that some fundamental dilemmas of upscaling can be identified, for example, the different understanding of the concept by researchers and practitioners. The dilemmas should be addressed in a more reflexive way by those from the worlds of science and practice who are involved in collaborative research settings.

Description: Businesses like Airbnb have shown that a successful circular economy (CE) business can operate exclusively online. Although online communication and web appearance attributes have been subject to academic research given accelerated digitization, there is still a lack of knowledge about online attributes and their role in facilitating CE. We close the portrayed knowledge gap by conducting a discrete-choice experiment with best to worst scaling and focusing on the effect of CE experience on the perception of a CE website by ranking nine online attributes, grouped in three subsets. We therefore contribute by identifying online attributes that are perceived as favorable for CE businesses and detect how participation in CE activities affects the perception of these attributes. We find that third-party associated online attributes (e.g., user reviews or third-party guarantees) rank significantly higher throughout CE consumption patterns of the sample, being always amongst the top three attributes. This novel finding on online preferences opens a new direction for further research, as well as allows practitioners to optimize online operations accordingly. Furthermore, we find that users without prior touchpoints with CE have a higher need for information about the business model as compared to CE active users who are more interested in community related attributes.

Description: Practices of urban experimentation are currently seen as a promising approach to making planning processes more collaborative and adaptive. The practices develop not only in the context of ideal-type concepts of urban experiments and urban labs but also organically in specific governance contexts. We present such an organic case in the city of Wuppertal, Germany, centred around a so-called change-maker initiative, "Utopiastadt." This initiative joined forces with the city administration and collaborated with a private property owner and the local economic development agency in an unusual planning process for the development of a central brownfield site. Ultimately, the consortium jointly published a framework concept that picked up the vision of the "Utopiastadt Campus" as an open-ended catalyst area for pilot projects and experiments on sustainability and city development. The concept was adopted by the city council and Utopiastadt purchased more than 50% of the land. In order to analyse the wider governance context and power struggles, we apply the social-constructivist theory of Strategic Action Fields (SAFs). We focused on the phases of contention and settlement, the shift in interaction forms, the role of an area development board as an internal governance unit and the influences of proximate fields, strategic action, and state facilitation on the development. We aim to demonstrate the potential of the theory of SAFs to understand a long-term urban development process and how an episode of experimentation evolved within this process. We discuss the theory's shortcomings and reflect critically on whether the process contributed to strengthening collaborative and experimental approaches in the governance of city development.

Description: The decarbonisation of the building stock is an important element for the success of the German Energiewende (energy transition). Despite some progress having been made, the rate of energy renovation falls below the level required to meet political commitments. This gives rise to the question: what deters property owners from making energy efficiency investments and how can the policy framework foster such investments? To answer this question, the paper focuses on a widely neglected property owner group: small private landlords (SPL). Although they manage 37% of all residential rental properties in Germany, very little is known about their decision-making processes for energy efficiency investments. We applied a mixed-method design to identify factors that hindered and supported their investments. In an explorative study, we initially conducted 18 problem-centred interviews. Subsequently, we carried out a postal survey and analysed the questionnaires using a hierarchical linear regression model. The results show that energy renovation is a multi-dimensional decision-making process, which can only be adequately addressed by a comprehensive policy package. To develop such a package, the author recommends that the specific investment behaviour of SPL must be better targeted, their knowledge about energy efficiency investments must be improved through exchange and networking, a sense of responsibility for the neighbourhood must be fostered, and greater focus must be placed on improving local framework conditions

Description: Die Grenzen des Verkehrswachstums sind erreicht. Klimaschutz und Lebensqualität sind wichtiger als hochgerüstete Autoflotten, die für Millionen Menschen ohne Auto Belastungen und Mobilitätsnachteile bedeuten. Notwendig ist eine radikale sozial-ökologische Transformation des Verkehrssystems: Ausbau und Förderung des Umweltverbundes aus ÖPNV, Schiene, Sharing-Systemen, Rad- und Fußverkehr - das sind bekannte Strategieelemente, die aber durch die herrschende Privilegierung des Autos ausgebremst werden. Dabei hat das Leitbild der autogerechten Stadt längst ausgedient. Entfesselte Automobilität frisst immer mehr Natur und Lebensqualität. Ziel muss es sein, nachhaltige Mobilität zu sichern, Verkehrsgerechtigkeit zu schaffen und die Hälfte der Autoflotte überflüssig zu machen. Und die Zukunft ist bereits unterwegs. Längst planen viele Städte eine menschengerechtere Mobilität: in Paris, Kopenhagen, Freiburg und anderswo. Unterstützt durch eine engagiertere Verkehrspolitik von Bund und EU, kann aus der kommunalen Verkehrsbewegung eine nachhaltige Mobilität für alle in Stadt und Land werden. Neue grüne Geschäftsfelder und gute Arbeit für moderne Mobilitätsdienstleistungen sind dabei Kernelemente. Mit den riesigen Maßnahmenprogrammen wegen der Corona-Pandemie und für den Klimaschutz kann ein gestaltender Staat die Chancen der Verkehrswende erschließen. Für dieses Gemeinschaftswerk können Wählermehrheiten gewonnen werden.

Description: Nie gab es mehr zu tun. Unsere Wirtschaft braucht nicht nur technische, sondern auch soziale und kulturelle Innovationen. Etablierte Wirtschaftsförderung beschränkt sich meist auf klassische gewerbliche Unternehmen und strebt nach Wettbewerbsfähigkeit und Wachstum. Das Konzept der Wirtschaftsförderung 4.0 geht darüber hinaus und betrachtet die gesamte Wirtschaft einer Stadt oder Region. Es ergänzt die klassischen Strategien und zielt darauf ab, lokale und regionale Wirtschaftsstrukturen zu stärken. Auch private und öffentliche Haushalte, Vereine und soziale Initiativen werden dabei berücksichtigt. Wirtschaftsförderung 4.0 initiiert so neue Wertschöpfung vor Ort, eröffnet lokale Investitionsmöglichkeiten, bindet regionale Kaufkraft, entfaltet neue Wirtschaftsideen, fördert Kooperationen und stärkt lokale Vielfalt. Zudem fördert sie Ressourcengerechtigkeit und Klimaschutz. Das Buch stellt diese innovative Wirtschaftsförderung vor, die die regionale und lokale Wirtschaft stabilisiert und Regionen dadurch widerstandsfähiger gegen globale Krisen macht.
