Description: 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.

Description: Effective actions to mitigate climate change are urgently needed, especially in the context of cities, which are major sources of global CO2 emissions. Establishing and managing knowledge systems that integrate local knowledge can contribute to establishing more effective responses to climate change as well as transformative change towards sustainability. However, it is still unclear how new forms of urban governance should acquire, store, create, or disseminate knowledge for fostering sustainability transitions effectively. In this study, we present a multilevel knowledge system approach based on design principles informed especially by the knowledge management literature. These address (i) working environments across multiple levels, (ii) knowledge forms and types, and (iii) knowledge processes. We apply this approach to municipal climate action in the German energy transition. In particular, we focus on the operational work of municipal climate action managers of regional centers of Lower Saxony, one of the largest of the 16 federal states, and investigate their involvement in knowledge processes. Based on semi-structured interviews in 14 of the 17 regional centers, we show that structural pre-conditions for successful knowledge management and organizational learning are present. However, we also show that there is a need for improvement regarding (i) the multilevel coordination for accelerating routine operation, (ii) the persistence of local operational knowledge, and (iii) the exploitation of local innovations. Relying on these results, we offer general recommendations for municipal climate action and suggest that policies should (i) rely on local knowledge for effective decision-making, (ii) foster multilevel exchanges of explicit and tacit knowledge for implementation, and (iii) enable open-ended learning processes that leverage local innovations for creating usable transformational knowledge.

Description: "Transformative science" is a concept that delineates the new role of science for knowledge societies in the age of reflexive modernity. The paper develops the program of a transformative science, which goes beyond observing and analyzing societal transformations, but rather takes an active role in initiating and catalyzing change processes. The aim of transformative science is to achieve a deeper understanding of ongoing transformations and increased societal capacity for reflexivity with regard to these fundamental change processes. The concept of transformative science is grounded in an experimental paradigm, which has implications for (1) research, (2) education and learning, and (3) institutional structures and change in the science system. The article develops the theoretical foundations of the concept of transformative science and spells out the concrete implications in these three dimensions.

Description: 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.

Description: In order to reconfigure global socio-economic systems to be compatible with social imperatives and planetary boundaries, a transition towards sustainable development is necessary. The multi-level perspective (MLP) has been developed to study long-term transformative change. This paper complements the MLP by providing an ontological framework for studying and understanding the role of narratives as the vehicle of meaning and intermediation between individual and social collective in the context of ongoing transitions. Narratives are established as an analytical entity to unpack how disturbances at the level of the socio-technical landscape are translated into and contribute to the transformation of socio-technical regimes. To illustrate and test the approach, it is applied to the case of the Fukushima catastrophe: The narratives in relation to nuclear power in Japan, Germany and the United Kingdom are scrutinized and it is explored how these narratives have co-determined the policy responses and thus influenced ongoing transformation processes in the power sectors of the respective countries.

Description: 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?"

Description: Sustainability research builds upon its mutual relationship with the society to find futureoriented solutions to deal with societal challenges. In other words, it is a matter of research to produce societal impact. Furthermore, funders and researchers themselves increasingly desire for accountability, to show if societal impact is achieved. To deal with that, two adaptive questions have to be answered: How can societal impact be understood or defined? And what can be learned from theoretical and methodological approaches, as well as practical examples? Built on the answers through a comprehensive literature review and expert interviews, the third question is asked: How can the assessment of societal impact of sustainability-oriented Projects look in practice? The result is the development of a holistic framework on the project-level and its operationalization. It was tested on three cases of the Wuppertal Institute, which has the mission to be a pulse generator for a sustainable societal transformation. The results show that the tool is implementable and a start of an assessment series. Nevertheless, the lack of consensus about the theoretical background influences the design of practical applications. One significant development is the focus shift of the assessment towards the project process and its productive interactions. This enables to collect data about whether societal impact is produced, but also how. The results suggest that clear assessment boundaries are required to deal with uncontrollable externalities. Furthermore, a practical question of the thesis is, if the integration of directly involved stakeholders into the assessment provide an added value. This can be answered positively. But it should be also observed that financial and human resources are key challenges about the extent, as well as the processing of the results. The analysis indicates that to assess societal impact is a suitable instrument and a key step to deal with societal challenges. The developed holistic framework and its operationalization can be used to inspire future research.

Description: Alternative power initiatives are socio-ecological innovations that substantially contribute to city's sustainable development and, therefore, are of particular societal benefit and value. Cities should, consequently, have an inherent interest in their existence and proliferation. This, however, asks for strategic innovation management. While, acknowledgement of the project's innovativeness constitutes the precondition for management, in the further process of steering activity the tasks to reduce hurdles, create open space and support the project's capacities need to be mastered. Thereby, cities are increasingly asked to become innovative themselves in order to find ways to optimally make use of their available tools and capacities.

Description: To identify the main drivers of transformation, it is helpful to identify the transformation perspectives of three specific schools of thought: idealist, institutional, and technological innovation. By differentiating among these schools of thought, a more informed transformation debate becomes possible, thereby increasing transformative literacy in academia and society.

Description: Addressing food waste prevention is one target of the Sustainable Development Goals (SDGs) and a major task for the UN Environmental Programme and the European Commission. It is promising in terms of its environmental saving potential. However, it also leads to consumers being able to save money, which they then are likely to spend, thus again causing a negative environmental impact. This dimension of the so-called indirect rebound effect, which prevents the desired ecological benefits from being achieved, is investigated in this paper. By using a single-region environmentally extended input-output model from a production perspective, the indirect rebound effects from food waste prevention in Germany are analysed. Any political action needs to consider not only a differentiation in income class, but also alternative concepts such as the principles of sufficiency in order to achieve all ecological benefits and specifically the third target of SDG 12.
