    Description: Striving to mitigate climate change, the European Union has adopted net-zero greenhouse gas emissions as a target for 2050. In this paper, European chemical industry roadmaps from the past six years are assessed and compared to uncover how the industry envisions its role in the transition to net-zero emissions. The roadmaps are assessed in terms of ambition level, technology and feedstock strategies, investment needs and costs, agency and dependency on other actors, as well as timeline and concretion. Although net-zero pathways are often drawn out in the roadmaps, some also choose to emphasize and argue for less ambitious pathways with emission reductions of only 40-60 %. The roadmaps vary widely in terms of the importance they assign to mechanical and chemical recycling, switching to biogenic carbon and carbon dioxide as feedstock, electrification and hydrogen, and carbon capture and storage. A commonality though, is that low-tech or near-term mitigation pathways such as demand reduction, reuse or material efficiency are seldom included. High investment needs are generally highlighted, as well as the need for policy to create enabling conditions, whereas the agency and responsibility of the chemical industry itself is downplayed. Our analysis highlights that the chemical industry does not yet have a strong and shared vision for pathways to net-zero emissions. We conclude that such a future vision would benefit from taking a whole value chain approach including demand-side options and consideration of scope 3 emissions.

    Description: Für die Landesregierung Nordrhein-Westfalen (NRW) ist die industriell genutzte Kohlenstoffabscheidung und -speicherung (engl. industrial carbon capture and storage, kurz iCCS) ein zentraler Baustein für den Übergang zu einer klimaneutralen Industrie bis 2045. Dafür braucht es aber eine breite gesellschaftliche Akzeptanz - zumal Pläne zur CO2-Abscheidung bei Kohlekraftwerken vor über zehn Jahren schon einmal an mangelnder gesellschaftlicher Akzeptanz gescheitert sind. In diesem In Brief haben die Autor*innen die Ergebnisse von zwei durchgeführten Akzeptanzstudien zu iCCS in NRW zusammengefasst und diskutieren, welche Handlungsempfehlungen sich daraus ergeben.

    Description: Innovative Finanzierungskonzepte wie Solar und Spar-Bürgercontracting belegen, dass ein riesiges Einsparpotenzial an Schulen wirtschaftlich erschlossen werden könnte. Doch bislang passiert zu wenig, um dieses auch zu nutzen. ­Das Projekt Schools4Future zeigt, wie Schulen eigenständig eine CO2-Bilanz erstellen können, um nicht nur eigene Klimaschutzmaßnahmen umzusetzen, sondern auch, um der Politik zu zeigen, wo dringender Handlungsbedarf besteht.

    Description: This paper presents a novel governance concept for sustainable development, introducing the "Safe System Approach" as a transformative model that shifts focus from individual behavioural change to systemic transformation. This approach challenges traditional governance models that emphasize individual responsibility in achieving sustainable development and decarbonization. Instead, it advocates for creating an enabling environment that inherently guides individuals and communities towards sustainable actions. The Safe System Approach is centred on delivering low-carbon services across essential sectors, including electricity, mobility, industry, buildings, human settlements, and agriculture, thereby embedding sustainability as a default choice in societal systems. Drawing parallels with successful models in road safety, the paper explores the potential of this approach in urban development and climate action. It emphasizes the need for a broad coalition and integrated approaches in managing shared resources, highlighting the significance of systemic adjustments over individual behavioral change. By proposing a structure where sustainability is facilitated by the system's design, the paper builds on key concepts from seminal works by scholars like Garrett Hardin, Mancur Olson, Elinor Ostrom, and Ahrend Lijphart. It discusses the challenges and opportunities in creating safe operating spaces for sustainable development, emphasizing the need for multi-actor, multilevel governance systems that can manage shared resources sustainably and are resilient to political volatility. The paper aims to offer a robust, efficient, and inclusive pathway to sustainable development, contributing to the global discourse on environmental and social resilience.

    Description: Angesichts von Extremwetterereignissen, Klimaprognosen und Bewegungen wie Fridays for Future lässt sich schwer leugnen, dass ein Teil der Menschheit auf eine Weise lebt, die eine gut bewohnbare Welt höchst unwahrscheinlich macht. Städten wird in dieser Situation eine zentrale Rolle zugeschrieben. Sie können die Welt vor der Erderwärmung retten - oder sie sind die Ersten, die untergehen. Doch was genau wird getan, um Städte in Richtung Nachhaltigkeit zu transformieren? Britta Acksel nimmt Aktionspläne, Klimafestivals, Awards und weitere Transformationsinstrumente in den Blick. Ethnographisch fundiert zeigt sie auf, wie sich die Arbeit mit dieser speziellen Form von Policy-Werkzeugen gestaltet - und welche Bemühungen besonders aussichtsreich erscheinen.

    Description: Ways of evaluating the societal impact of real-world labs as a transdisciplinary and transformative research format are under discussion. We present an evaluation approach rooted in structuration theory, with a focus on structure-agency dynamics at the science-society interface. We applied the theory with its four modalities (interpretation schemes, norms, allocative and authoritative resources) to the case of the Mirke neighbourhood in Wuppertal, Germany. Six projects promoted the capacity for co-productive city-making. The effects of the projects were jointly analysed in a co-evaluation process. Previously proposed subcategories of the modalities as an empirical operationalisation were tested and confirmed as being applicable. Five new subcategories were generated. The use of the modalities seems appropriate for co-evaluation processes. The tool is practical, focused on real-world effects, and suitable for transdisciplinary interpretation processes. We encourage further empirical testing of the tool, as well as development of the subcategories.

    Description: Real-world laboratories (RwLs) are gaining further traction as a means to achieve systemic impacts towards sustainability transformation. To guide the analysis of intended impacts, we introduce the concept of leverage points, discerning where, how, and to what end RwLs intervene in systems. Building on conceptual reasoning, we further develop our argument by exploring two RwL cases. Examining RwLs through the lens of the leverage points opens the way for a balanced and comprehensive approach to systemic experimentation. We invite RwL researchers and practitioners to further advance RwLs' transformative capacity by targeting the design and emerging direction of a system, contributing to a culture of sustainability.

    Description: Für Deutschland und viele Industrieländer weltweit wird der Import von grünem Wasserstoff ein zentraler Baustein auf dem Weg zur Klimaneutralität sein. Dabei muss einerseits gewährleistet sein, dass grüner Wasserstoff auch wirklich "grün" im Sinne von klimaneutral ist. Zugleich gibt es immer mehr Forderungen, dass auch andere Nachhaltigkeitskriterien - soziale, ökonomische und ökologische - bei der Produktion und dem Transport von Wasserstoff eingehalten werden. Der politisch getriebene Aufbau einer globalen Wasserstoffwirtschaft bietet von Anfang an die Möglichkeit, diesen Sektor in Einklang mit den bestehenden politischen Zielen zu bringen. Dazu zählen beispielsweise die Pariser Klimaziele oder die Agenda 2030. Die Industrienation Deutschland, die auch in Zukunft auf Energieimporte angewiesen sein wird, kann hier als führende Industrienation als Vorreiter Einfluss nehmen. Damit kann nicht nur sichergestellt werden, dass der nach Deutschland importierte Wasserstoff "grün und nachhaltig" ist, sondern auch die Nachhaltigkeit des globalen Wasserstoffmarktes insgesamt beeinflusst werden. Diese Kurzstudie untersucht, welche bereits existierenden Politikinstrumente geeignet sind, Nachhaltigkeitskriterien für Wasserstoffimporte zu verankern und im Zusammenspiel den Weg zu einem nachhaltigen globalen Wasserstoffmarkt zu unterstützen. Dabei werden ausschließlich Nachhaltigkeitsziele und -kriterien jenseits der Klimawirkung von Wasserstoff analysiert. Es ist unbestritten, dass das zentrale Ziel der Wasserstoffwirtschaft die Reduktion von Treibhausgasen bis hin zur Klimaneutralität ist, was bereits in einer Vielzahl von Studien und Stellungnahmen diskutiert wurde. Daher wird in dieser Studie von der Klimaneutralität des grünen Wasserstoffs ausgegangen, um den Fokus auf die anderen wesentlichen Nachhaltigkeitsaspekte zu lenken, die für den Import von grünem und nachhaltigen Wasserstoff aus dem Globalen Süden von entscheidender Bedeutung sind.

    Description: Die schnelle und umfassende Emissionsminderung in der Energie- und Kreislaufwirtschaft ist der Schlüssel für die Begrenzung der Erderwärmung auf unter 2 °C. In Deutschland werden entsprechende Politiken seit den 1990er-Jahren verfolgt, allerdings erst in jüngster Vergangenheit mit dem notwendigen Nachdruck und der notwendigen Orientierung hin zu mehr Marktmechanismen. Wesentliche Handlungsfelder sind Energieeinsparung und erhöhte Energieeffizienz, Umstieg auf erneuerbare Energien, Bepreisung von Klimagasen sowie eine Reduzierung und Schließung der Stoffkreisläufe. In allen Handlungsfeldern sind Grundlagen geschaffen, es bleibt jedoch der Großteil des Weges noch zu gehen, um Klimaneutralität zu erreichen. Für einen schnellen Fortschritt spielen neben der Überwindung der technischen, ökonomischen und organisatorischen Herausforderungen auch Verteilungsfragen und die Einbettung in internationale Maßnahmen eine zunehmende Rolle.

    Description: The co-operation between municipalities and civil society actors and their independent impulses for urban development are discussed under the terms of co-production and city-making. This article summarises these activities as co-productive city-making (koSM). Forms of as well as advantages and disadvantages of koSM have been discussed in research and practice so far, but analyses of the longitudinal genesis of these activities and their significance for the development of a specific area are rare. This article uses the longitudinally collected, mixed-method data of a constellation analysis of the development of the Mirke neighbourhood in Wuppertal/Germany. Based on four points in time, the dynamics as well as the spatial development of the koSM can be presented - individually and in comparison to other developments. It can be seen that the koSM in the Mirke has grown at an above-average and dynamic rate and can accordingly be interpreted as a motor of neighbourhood development. Main actors and locations are identified. The study is the basis for a follow-up work analysing the reasons and structural effects of the koSM. The koSM is discussed both in its interrelations with municipal action and in its significance for integrated and sustainable urban development. The method of constellation analysis is critically discussed with regard to the relationship between effort and benefit.

    Description: Real-world labs are witnessing continued growth and institutionalization in the field of transformation-oriented sustainability research, as well as in adjacent disciplines. With their experimental research agendas, these labs aim at sustainability transformations, however, there is still a need to improve the understanding of their impacts. Drawing from this Special Issue's contributions, we offer a broad overview of the impacts achieved by various real-world labs, highlight the diverse areas and forms of impact, and elucidate strategies as well as mechanisms for achieving impact. We present methodological advances, and address common challenges along with potential solutions for understanding and realizing impact.

    Description: Deutschlands Haushalte werden, zu Beheizungszwecken, zu 70 % leitungsgebunden versorgt: 50 % mit Erdgas und 14 % mit Fernwärme; 5 % mit Elektrizität, davon je die Hälfte noch mit Nachtspeicherheizung, die andere Hälfte mit Wärmepumpen. So war es 2021. So wird es in Zukunft nicht sein, denn Erdgas ist ein Energieträger fossiler Herkunft. Dessen Nutzung geht in den nächsten beiden Jahrzehnten gen Null. Die Frage ist, was das für die Erdgasleitungen in Deutschland bedeutet.

    Description: The petrochemical industry is among the most relevant sectors from an economic, energetic and climate policy perspective. In Western Europe, production occurs in local chemical parks that form strongly connected and densely integrated regional clusters. This paper analyzes the structural characteristics of the petrochemical system in Germany and investigates three particularly distinct clusters regarding their challenges and chances for a transition towards climate-neutrality. For this, feedstock and energy supply, product portfolios and process integration as well as existing transformation activities are examined. We find that depending on their distinct network characteristics and location, unique and complex strategies are to be mastered for every cluster. Despite the many activities underway, none of them seems to have a strategic network to co-create a tailored defossilization strategy for the cluster - which is the core recommendation of this paper to develop.

    Description: Demand-side mitigation strategies have been gaining momentum in climate change mitigation research. Still, the impact of different approaches in passenger transport, one of the largest energy demand sectors, remains unclear. We couple a transport simulation model to an energy system optimisation model, both highly disintegrated in order to compare those impacts. Our scenarios are created for the case of Germany in an interdisciplinary, qualitative-quantitative research design, going beyond techno-economic assumptions, and cover Avoid, Shift, and Improve strategies, as well as their combination. The results show that sufficiency - Avoid and Shift strategies - have the same impact as the improvement of propulsion technologies (i.e. efficiency), which is reduction of generation capacities by one quarter. This lowers energy system transformation cost accordingly, but requires different kinds of investments: Sufficiency measures require public investment for high-quality public services, while efficiency measures require individuals to purchase more expensive vehicles at their own cost. These results raise socio-political questions of system design and well-being. However, all strategies are required to unleash the full potential of climate change mitigation.

    Description: The sustainable transformation of society is one of the greatest challenges of our time. Universities are central actors for knowledge generation and transfer in the sustainability field and, at the same time, are facing the question of how they can become sustainable social actors and make their activities and infrastructure sustainable. Against this background, the 16 member universities of the State Rectors' Conference of North Rhine-Westphalia have joined forces in the Humboldtn initiative to pool their efforts in the field of sustainability and to anchor generational responsibility for sustainable action in research, teaching, administration, infrastructure, and transfer. How the joint responsibility for the questions for the future in the aforementioned complex of topics is addressed via Humboldtn and which focal points are set in the process will be presented and discussed using examples from the institutional sustainability transformation and examples from the research area from RWTH Aachen University. In this way, the implementation of transformation processes at universities and their possible blueprint effect can be illuminated.

    Description: The global building sector, responsible for over 30% of CO2 emissions, necessitates urgent decarbonization efforts. This paper examines residential building decarbonization policies in three major economies - the European Union (EU), China, and India. It provides an overview of diverse policies through policy landscape analysis and delves into the design specifics with a detailed policy intensity analysis of building energy codes, information disclosure, and financial incentives in each region. Our findings reveal a diverse mix of policies targeting residential building decarbonization in all three regions. While the EU and China have long-established diverse policy instruments, India's building energy efficiency policies are relatively recent and limited. Detailed analyses of building energy codes, information disclosure, and financial incentives expose variations in ambition, scope, and implementation, even with shared policy instruments. Significant advancements in building energy codes, particularly in stringency and compliance checks, are evident in the EU and China. Conversely, India faces a notable obstacle with limited adoption of residential building energy codes, impacting its journey towards net-zero. The EU leads in building energy labelling policies, while China and India encounter various challenges hindering widespread implementation. Financial incentives across the three regions predominantly take the form of subsidies, potentially straining public budgets. The study concludes with reflections on the pressing need for future research extending beyond the operational phase of buildings.

    Description: Energy performance contracting (EPC) as a market instrument has been effective in promoting energy efficiency worldwide, but it has encountered many insurmountable obstacles in rural energy management. In this study, based on the characteristics of energy management in rural areas, three EPC modes are designed and tested in 24,000 rural households. The test results show that two adapted EPC modes of local government involvement and energy payment directly from the national grid can effectively overcome the barriers encountered in the traditional EPC modes and work well under the economic and social environmental conditions in rural areas. The key to the adaptation of the traditional EPC modes is the introduction of the local government as the third party. Participation of the third party can effectively reduce and remove the barriers and risks and increase the mutual trust between the clients (households) and the energy service companies (ESCOs). Based on the testing results, this study suggests that governmental departments should formulate relevant EPC policies and technical guidelines within the rural context. This research recommends that farmers should not manage their energy services by themselves and it is suggested to out-contracting ESCOs by applying the modes developed and tested by this paper.

    Description: In Germany, there are over 32,000 schools, representing great potential for climate protection. On the one hand, this applies to educational work, as understanding the effects of climate change and measures to reduce GHG emissions is an important step to empower students with knowledge and skills. On the other hand, school buildings are often in bad condition, energy is wasted, and the possibilities for using renewable energies are hardly used. In our "Schools4Future" project, we enabled students and teachers to draw up their own CO2 balances, identify weaknesses in the building, detect wasted electricity, and determine the potential for using renewable energies. Emissions from the school cafeteria, school trips, and paper consumption could also be identified. The fact that the data can be collected by the students themselves provides increased awareness of the contribution made to the climate balance by the various school areas. The most climate-friendly school emits 297 kg whilst the school with the highest emissions emits over one ton CO2 per student and year. Our approach is suitable to qualify students in the sense of citizen science, carry out a scientific investigation, experience self-efficacy through one's own actions, and engage politically regarding their concerns.

    Description: In the race against time, the European Union must move swiftly to navigate the green transition. This imperative isn't just about staying ahead in the global green technology competition; it is about securing the future of Europe's economy while combating climate change. Ahead of the EU elections looming, the urgency of this dual challenge cannot be overstated. With a new pro-EU Polish government in place, the Weimar Triangle - a trilateral forum that brings together Poland, France and Germany - could provide the ideal place to offer a new bold industrial policy leadership in Europe.

    Description: The twenty-eighth Conference of the Parties (COP28) to the United Nations Framework Convention on Climate Change (UNFCCC) in Dubai among many other items concluded the first Global Stocktake (GST) under the Paris Agreement. This article discusses the conference's outcomes in the areas of mitigation, loss and damage, adaptation, climate finance, and cooperation under Article 6 of the Paris Agreement. The conference arguably made history by for the first time ever recognising the need to "transition away" from fossil fuels, adopting specific targets for the scale-up of renewable energy and energy efficiency, and by operationalising a fund to support developing countries in dealing with loss and damage caused by climate change. However, the legal language in the call for an energy transition is relatively non-committal and the conference failed to underpin the new global objectives with adequate resources. Actual implementation of the Dubai outcomes will therefore to a large extent depend on whether COP29 in Baku, Azerbaijan - already billed as "finance COP" - will be able to cut the Gordian knot of finance.

    Description: North Rhine-Westphalia (NRW) is the industrial center of Germany and one of the most important industrial locations in Europe. It is a key location for the energy-intensive basic materials industry like the production of steel and non-ferrous metals, (petro)chemicals, cement and lime, bricks, glass and ceramics, and paper. Around 20 % of NRW's total greenhouse emissions derive from industrial processes. By 2045, industry must achieve climate-neutrality, which requires a massive transformation effort. Technologically, this needs large-scale utilization of green hydrogen, carbon management, consequent circular economy, and climate-neutral production of process heat. Furthermore, various adjustments to the policy framework are essential.

    Description: The goal of this dissertation is to facilitate the assessment of impacts from sustainable measures and projects with an emphasis on impact reporting for Green, Social or Sustainability Bonds in the Sustainable Finance market. It does so by providing analysts with the means to develop, depict, formulate, and assess a causal hypothesis between an intervention and its subsequent effects in an impact-chain, represented by desired environmental (E), social (S) or governance (G) changes. This is achieved by developing a methodology for so-called ESG Logic Models or ESG-LM, that combine heuristic Theories-of-Change with propositional logic and Bayesian Reasoning. Three research questions are investigated and responded to. Research Question 1 asks how such Theories-of-Change can be developed for any type of ESG-related issue and how the different process steps in a causal chain can be classified, hierarchised, and prioritised regarding their efficacy towards overarching sustainability goals and their plausibility. Research Question 2 studies (a) the means by which the analyst or any other interested third party might be warranted in believing the causal claims from an ESG-LM, and (b) how an ESG-LM can be improved if this credence is low. Research Question 3 then looks at the reporting of impacts themselves regarding indicator selection, indicator assessment and indicator quantification as well as the provision of information on the contributions and attributions by different actors. The dissertation draws on a variety of theories and adapts existing methods to achieve that. It operationalises concepts from empirical Sustainable Finance research and already existing impact assessment methodologies. It adapts scholarly and practitioner approaches for theory-based evaluation and applies a qualitative social science perspective towards theory-building and evaluation, while some of the assessment tools in the dissertation are grounded in Logic, Set Theory and Bayesian Epistemology. Examples for such tools include rules for the Attribution by actors, heuristics for the abduction of plausible outcome pathways, or a four-stage Argument and Decision-Tree to assess the credibility of ESG-LM claims (based on Bayes Theorem). My assessment of the entire methodology is positive overall, as it provides solutions to each of the three research areas. Limitations of the approach, and thus opportunities for further research, are the additional expertise and time required by analysts compared to the existing, and somewhat more pragmatic, solutions in the current market. However, this is outweighed in my opinion by the ability of the framework to strongly mitigate impact washing by actors in the financial markets as well as biases by analysts. Its overall methodology also provides opportunities for new research angles in the area of sustainability indicators and assessments.

    Description: Dieser Bericht befasst sich mit dem ⁠Monitoring⁠ und der Evaluation von ProgRess III. Der Bericht geht über die Analyse der Ressourceneffizienz auf volkswirtschaftlicher Ebene hinaus und evaluiert insbesondere die Umsetzung der Maßnahmen, die mit ihnen verbundenen Effekte und die zugrundeliegenden Erfolgsfaktoren. Dazu wurde ein zweistufiges Verfahren durchgeführt: ein Monitoring und eine Evaluation des Programms. Nach einer Einführung in die Ziele der Evaluation und der Abgrenzung zum zuvor durchgeführten Monitoring (Kap. 1) werden die Forschungsfragen und die Elemente eines erfolgreichen Politikmix, wie er in der theoretischen Forschung diskutiert und konzipiert wird, kurz erörtert (Kap. 2). Dann werden die Methoden (Analyse, Interviews, Webcrawling) und der Fahrplan der Evaluation vorgestellt (Kap. 3). Zwei Wirkungsmodelle, ein materielles und ein organisationales ⁠Wirkmodell⁠, bilden die Basis für die verschiedenen Betrachtungsebenen und Foki, die für die Evaluation gewählt wurden. In Kapitel 4 werden schließlich die Erkenntnisse, die durch den Einsatz der verschiedenen Methoden gewonnen wurden, in bewusst kompakter und übersichtlicher Form in Bezug zu den Evaluationskriterien dargestellt und Empfehlungen abgeleitet. Kapitel 5 widmet sich der Gesamtbewertung der Effektivität von ProgRess III und Kapitel 6 bearbeitet abschließend die Frage, welche Entwicklungspotenziale aus den gewonnenen Erkenntnissen abgeleitet werden können.

    Description: This focus article traces the evolution of the voluntary carbon market (VCM), putting emphasis on the more recent developments following the adoption of the Paris Agreement in 2015. It focuses on the interplay between the privately governed VCM and the global climate regime under the United Nations (UN). For years, the VCM and the UN carbon market operated in parallel and mutually influenced each other. The adoption of the Paris Agreement, however, marked a turning point for the VCM. It triggered the proliferation of net zero targets, sparking the interest in the VCM as a supplier of carbon credits to offset companies' remaining emissions. At the same time, the global scope and ambitious targets set by the agreement have put the future of the VCM in limbo, raising concerns about double claiming and more generally, questioning the adequacy of offsetting. Considering these challenges, numerous stakeholders have started a process to redefine the rules of the market to ensure its credibility and legitimacy. While some areas of convergence were identified, the VCM's private governance has long been unable to address the question of how to deal with double claiming and the claims companies should be allowed to make. In this situation, signals from international policy and regulation under national policy point the way forward for the VCM. By moving from offsetting toward a contribution claim model, the VCM may overcome its "identity crisis" and find a new place within the broader climate change regime.

    Description: As the climate crisis is accelerating and the pressure to act is steadily increasing, many companies are claiming themselves or their products carbon neutral. This is usually achieved by offsetting residual emissions with carbon certificates (carbon offsetting). However, recent revelations about the inadequate quality of carbon credits and legal uncertainties surrounding the use of such offset claims are increasingly raising doubts about this approach. This Wuppertal Report examines how the EU can promote integrity in corporate climate action. Taking into account the new framework of the Paris Agreement, the paper outlines various options for how the EU could push for more integrity and effectively combat greenwashing through the targeted use of Article 6 of the Paris Agreement. In their recommendations, the authors advocate addressing the most serious consequences of ongoing offset practices through increased regulation of offset claims. If a ban on offset claims cannot be implemented, claims requirements and carbon offset regulations should be further specified, for example, by prohibiting any type of double counting of emissions reductions. In addition to tightening the rules for corporate offset claims within Europe, the EU could help partner countries make informed decisions when approving climate change mitigation measures and respective carbon credits. The report also emphasizes the EU's special role in international climate negotiations, where it should advocate for a strong legal framework for climate action under Article 6.

    Description: Die verheerenden Mengen an Abfall am Ende des Lebenszyklus von Produkten zu bewältigen, gilt als eine der größten Herausforderungen auf dem Weg zu einer Circular Economy. Die negativen Folgen, die sich aus dem Missmanagement von Kunststoffabfällen aufgrund fehlender oder nicht funktionierender Abfallwirtschaftsstrukturen in weiten Teilen der Erde ergeben, werden zunehmend deutlich. Bei der Circular Economy als elementarer Lösungsansatz sollen Stoffströme geschlossen und Produktlebenszyklen verlängert werden. Ein Instrument zur Annäherung an dieses Modell ist der Handel mit sogenannten Plastic Credits - ein Mittel, um den Ausbau regionaler Infrastrukturen für die Sammlung und das Recycling von Kunststoffabfällen zu finanzieren. Die Abnehmer von Plastic Credits sind die treibende Kraft hinter dem Mechanismus. Es ist weiterführende Forschung notwendig, insbesondere in Bezug auf die Frage, wie Unternehmen das Instrument der Plastic Credits nutzen und in ihre Gesamtstrategie integrieren. Diese Masterarbeit widmet sich der dabei vorgelagerten Frage: Existieren bestimmte Profile bei Unternehmen, die in Plastic Credits investieren, und lassen sich hierbei spezifische Cluster bilden? Im Rahmen der Beantwortung dieser Frage wurden Expert*innen-Interviews mit Hilfe der qualitativen Inhaltsanalyse nach Mayring ausgewertet. Dabei haben sich drei konkrete Unterfragen ergeben, die sich auf die Motivation, Branchenzugehörigkeit und räumliche Verortung der Abnehmer beziehen. Die Ergebnisse zeigen, dass sich die Abnehmer von Plastic Credits bereits umfangreich mit der Kunststoffabfallproblematik und der damit verbundenen Auswirkung auf die Umwelt beschäftigen. Offen bleibt, inwiefern Maßnahmen zur Vermeidung von neuartigem Kunststoff, der Verbesserung der Recyclingfähigkeit der Produkte oder der Einsatz von Rezyklaten in der Herstellung dem Weg der Kompensation vorangestellt werden. In Bezug auf die Branchenzugehörigkeit legen die Ergebnisse nahe, dass vorrangig Unternehmen, die mit einem erschwerten Rezyklate-Einsatz konfrontiert sind, in Plastic Credits investieren. Welche Auswirkungen Maßnahmen wie die Entbürokratisierung der Zulassungsverfahren für neue Recyclingprozesse oder verpflichtende Anteile an recycelten Materialien in bestimmten Produkten auf die Investition in Plastic Credits haben, wird sich in Zukunft zeigen. Die Analyse der räumlichen Verortung gab Aufschluss darüber, dass zurzeit im Wesentlichen Unternehmen aus dem globalen Norden in Plastic Credits investieren - jedoch verbunden mit dem Ziel, eine Finanzierung aus den Projektländern heraus zu intensivieren.

    Description: Förderbanken vergeben in Deutschland jährlich mindestens 200 Milliarden Euro an Mitteln für Investitionen, die sonst nicht oder sehr viel später umgesetzt werden könnten. Sie arbeiten im öffentlichen Auftrag und richten ihre Tätigkeit an gesellschaftlichen Zielen aus. Diese Ziele haben sich weiterentwickelt. Angesichts von Klimawandel, Energiekrise und den Herausforderungen einer Kreislaufwirtschaft wollen sowohl die Länder als auch die Bundesregierung ihre Förderbanken umbauen. Gerade die Förderbanken der Länder müssen sich darum jetzt bereit machen für die "Weiterentwicklung von Förderbanken zu Transformationsbanken". Für die erfolgreiche Gestaltung dieses gesellschaftlichen Umbruchs brauchen sie Unterstützung. Wie dies gelingt, zeigt dieser Zukunftsimpuls.

    Description: Junge Menschen sehen sich durch die Klimakrise einer Einschränkung ihrer Entfaltungs- und Lebensmöglichkeiten gegenübergestellt. Diese explorative Studie verdeutlicht, wie sowohl die Wahrnehmung der Klimakrise, die Verantwortungsattribution, die wahrgenommene Handlungswirksamkeit und die einschlägigen Sozialisationserfahrungen milieuspezifisch strukturiert sind. Informiert durch das Projekt Schools4Future wurden vier Leitfadeninterviews mit Schüler*innen zur Wahrnehmung und Deutung der Klimakrise geführt. Im dreischrittigen Kodierprozess der Grounded Theory konnten Muster der Betroffenheit, der Verantwortungsattribution und der Handlungsstrategien von vier jugendlichen Klimaaktivist*innen aus akademischen und prekären Herkunftsmilieus rekonstruiert werden. Während die sozial bevorteilten Jugendlichen sich als Betroffene und unter dem Fehlverhalten vorangehender Generationen leidende Gruppe wahrnehmen, sehen die sozial benachteiligten Jugendlichen die Klimakrise als ein systemisches Versagen neben anderen. Der medial so vertraute Aktivismus geht von dem gehobenen Milieu aus und verbindet sich mit Konsum als distinktive Praxis des klimafreundlichen Handelns. Im prekären Milieu zeigen sich andere Formen des stillen, konkreten und intrinsisch motivierten Engagements sowie das (schulische) Engagement als Investition in den individuellen, sozialen Aufstieg. Konsistenter Weise sehen sich die akademischen Jugendlichen als bevorteilt in der Bearbeitung der Klimakrise, dethematisieren aber, was die jungen Menschen aus dem sozial schwachen Milieu deutlich diagnostizieren: Der ökologische Fußabdruck ihres Konsums ist ungleich höher als der der benachteiligten Jugendlichen.

    Description: In einer umkämpften Stadt wird der Anbau von Nahrung zu einem politischen Akt: Anbau, Erwerb von Nahrung und ihre sozialen und umweltbezogenen Qualitätskriterien sind eng verknüpft mit dem "Recht auf Stadt", wie es der französische Soziologe Henri Lefebvre formuliert hat. Anhand verschiedener Dimensionen dieses "Rechts auf Stadt" untersucht Katharina Gröne drei Landwirtschaftsprojekte in Kapstadt/Südafrika - mit Blick auf die kommunikative und die mikropolitische Ebene sozialökologischer Praktiken. Aufgrund ungleicher sozialräumlicher Entwicklung, Teilhabe und Anerkennung durch die Politik nehmen diese drei Projekte jeweils unterschiedliche Positionen im alternativen Nahrungsmittelnetzwerk Kapstadts ein. Kulturelle Artefakte, Symbole, Logos und Begriffe dienen dabei der Herstellung sozialer Ordnung und eines spezifischen Repräsentationsregimes im politischen Feld. So wird der Anbau von Gemüse zum Austragungsort eines Machtkampfes - und dient der Herstellung kultureller Hegemonie in der städtischen Nachhaltigkeitspolitik.

    Description: In view of the accelerating climate crisis, the Russian invasion of Ukraine highlighted the dependency of fossil fuels on the part of Germany and the European Union (EU). With the priority aim to reduce the import dependency from the Russian Federation while providing energy security and staying on track with climate mitigation efforts, the Federal Government was presented with major challenges. Prior to the war, an approximate 34% of the mineral oil, 53.6% of the natural gas, and 50% of hard coal supplies to Germany originated from Russian sources. As of 2023, however, Germany is independent from Russian energy imports. This paper examines implications of the global energy crisis induced by the invasion on the energy sector in Germany. As a basis for achieving this analysis, a short overview of the energy situation in the country before the war and a demonstration of the provisional conditions is presented. This is followed by an analysis of the main consequences of the war and medium and long-term strategies to reach Germany's climate goals while maintaining energy security. Lastly, foreseeable consequences regarding the European and German climate goals are discussed.

    Description: Junge Menschen sehen sich durch die Klimakrise einer Einschränkung ihrer Entfaltungs- und Lebensmöglichkeiten gegenübergestellt. So überrascht es nicht, dass gerade die junge Generation sich aktiv für mehr Klimaschutz einsetzt - doch sind es wirklich alle Jugendlichen, die auf die Straße gehen? Die vorliegende explorative Studie zeigt auf, wie sowohl die Wahrnehmung der Klimakrise, die Handlungsmuster und auch die Verantwortungsattribution - individuell, innergenerational und politisch - milieuspezifisch verhandelt werden. Informiert durch das Projekt Schools4Future wurden vier Leitfadeninterviews mit Schüler*innen zur Wahrnehmung und Deutung der Klimakrise geführt. Im dreischrittigen Kodierprozess der Grounded Theory konnten Muster der Betroffenheit, der Verantwortungsattribution und der Handlungsstrategien von vier jugendlichen Klimaaktivist*innen aus akademischen und prekären Herkunftsmilieus rekonstruiert werden.

    Description: Lange Zeit hoffte man, die Lebensgrundlagen durch den Einsatz immer besserer Technologien sichern zu können. Doch optimierte Prozesse allein bringen keine Klimawende. Wir kommen als Gesellschaft nicht umhin, das rechte Maß, Genügsamkeit und ja, auch Verzicht zum Querschnittsthema zu machen.

    Description: Im September 2023 sind zwei wenig ermutigende Untersuchungen veröffentlicht worden: Das Klimasekretariat der Vereinten Nationen macht in seinem Report zur ersten Globalen Bestandsaufnahme (Global Stocktake) deutlich, dass die bisher zugesagten nationalen Klimaschutzbeiträge bei weitem nicht genügen, um die Pariser Klimaschutzziele zu erreichen. Auch das Update zur Einhaltung der planetaren Grenzen fällt ernüchternd aus: In sechs von neun Bereichen sind die Grenzen teils weit überschritten - auch in Bezug auf den Klimawandel. Allerdings reichen die ergriffenen Klimaschutzmaßnahmen nicht aus, um die gesteckten Ziele zu erreichen. Suffizienzstrategien und -politik können den Wandel bringen - bei Konsum, Gebäuden, Verkehr, Kreislaufwirtschaft und Energie, wie der Zukunftsimpuls zeigt.

    Description: Die Schaffung von bezahlbarem und sozial gerechtem Wohnraum stellt eine zentrale Herausforderung der nachhaltigen Stadtentwicklung dar. Zur Begegnung dieser Herausforderungen spielen innovative Wohnformen wie gemeinschaftliche Wohnprojekte eine bedeutende Rolle, da sie vielfältige soziale Nachhaltigkeitsaspekte aufweisen und dadurch zu einer nachhaltigen Stadtentwicklung beitragen können. In diesem Kontext bleibt die Frage offen, ob die Gemeinschaften in Wohnprojekten nach ihrer Gründung beständig bleiben. Das Ziel der Arbeit war die Beantwortung der folgenden Forschungsfrage: "Wie können gemeinschaftliche Wohnprojekte dauerhaft in Bezug auf ihre Weiterentwicklung bestehen bleiben und somit langfristig eine nachhaltige Stadtentwicklung unterstützen?" Zur Beantwortung der Forschungsfrage wurde eine qualitative Studie in Form von narrativen Interviews mit Bewohner:innen gemeinschaftlicher Wohnprojekte durchgeführt. Die Ergebnisse aus Literatur und Praxis konnten acht besonders relevante Faktoren für die Beständigkeit von gemeinschaftlichen Wohnprojekten identifizieren: Soziale Durchmischung, Organisationsstruktur, Gemeinschaftspflege, Vertrauen, Soziales Netzwerk, Kommunikationskultur, gelebte Nachhaltigkeit, Flexibilität und Anpassungsfähigkeit. Diese Faktoren ermöglichen eine nachhaltige und anpassungsfähige Gemeinschaft, welche zu einer nachhaltigen Stadtentwicklung beitragen kann. Dafür sollten gemeinschaftliche Wohnprojekte ihre vorhandenen Potenziale weiterhin ausbauen.

    Description: The COVID-19 pandemic has jolted societies out of normality, possibly creating new conditions for sustainability transformations. What does this mean for sustainability research? Because of the scope of the crisis, researchers have been heavily involved: not only have they had to speed up the pace of scientific production to provide urgently needed COVID-19 knowledge, but they have also been affected citizens. For sustainability science, this calls for an experience-based reflection on the positionality and orientation of research aiming to support sustainability transformations. Twenty sustainability researchers discussed their sustainability research on COVID-19 in three workshops based on the following questions: How does the pandemic - and the measures taken to deal with it - affect sustainable development? What can we learn from the pandemic from the perspective of societal transformation? The present discussion paper emerged from this multidisciplinary exchange among sustainability researchers, considering five topics: impacts of the COVID-19 crisis on sustainability transformations; learning for sustainability transformations; the role of solidarity; governance and political steering; and the role of science in society. Our discussions led to a meta-level reflection on what sustainability research can learn from research on COVID-19 regarding topics and disciplinary angles, time dimensions, the role of researchers, and how adequate preparation for both crises and long-term transformations requires interdisciplinary interaction.

    Description: The transition to a greener and more circular economy has been a European policy priority for several years. The Circular Economy Action Plan of 2020 underlines the ambition. The following EEA initiatives are meant to support the transition process: - Bellagio Process on circular economy monitoring principles (EPA network); - Enhancement of EEA indicators on circular economy (ETC/WMGE); - Explorative work on novel data streams (FWC); - Co-creation work - knowledge sharing of monitoring experience (ETC/Eionet). The scope of the present task was to report on the co-creation process that was undertaken at the end of 2020. The co-creation process was organised to identify: (i) best practices on monitoring strategies, data sources and target setting; and (ii) areas of circularity measuring and monitoring that remain challenging and require additional investment. The co-creation process partially built on the work done during the Bellagio Process/Initiative which was run in parallel. This ETC report presents and documents the evidence gathered throughout the co- creation process as well as providing a retrospective analysis of the links to the Bellagio Principles.

    Description: As investors and financial intermediaries, private banks are increasingly confronted with climate change concerns. But to what extent do banks identify as the changemakers driving climate alignment forward? To advance this question, this paper analyzes the South African banking sector with a specific focus on Standard Bank and Nedbank as exemplary case studies. Relying on the concept of "climate mainstreaming", we critically assess the banks' annual reports and compare their self-portrayal with publicly available sources on the bank's business practices, chiefly provided by non-governmental organizations and media. We find that Nedbank pushes a holistic narrative of climate change as an inevitable business opportunity. Standard Bank, in turn, relies on a "narrative of balance" between climate change and other profit-oriented investments to safeguard its stakes in the fossil industry. In so doing, this paper sheds light on greenwashing practices within disclosure specifically and the lack of binding corporate regulation more generally.

    Description: In Deutschland werden jährlich über sieben Millionen gebrauchte Matratzen entsorgt, die überwiegend verbrannt und nur zu einem Bruchteil recycelt werden. Dieser lineare Ansatz belastet die Ressourcen, erhöht die Emissionen und birgt Umweltrisiken. Um diesen Herausforderungen zu begegnen, kann die erweiterte Herstellerverantwortung (Extended Producer Responsibility, EPR) als Instrument zur Umsetzung einer Kreislaufwirtschaft dienen. In dieser Masterarbeit wird daher untersucht, wie ein EPR-System für Matratzen in Deutschland gestaltet sein sollte, um Kreisläufe effizient zu schließen. Gleichzeitig zielt diese Thesis darauf ab, die damit verbundenen Anforderungen und Herausforderungen bei der Umsetzung eines solchen Systems zu identifizieren. Zur Beantwortung der Forschungsfragen wurden mithilfe von Expert*innen-Interviews und einer umfassenden Literaturrecherche drei EPR-Modelle entwickelt und anhand von ausgewählten Kriterien bewertet. Die Ergebnisse der Bewertung ergaben, dass ein Modell präferiert werden sollte, in dem eine sogenannte Producer Responsibility Organisation (PRO) gebündelt die Verantwortung der Hersteller übernimmt. Ein solches System würde unter anderem eine angemessene Kontrolle ermöglichen und Anreize für Forschung und Entwicklung im Bereich der Recyclingtechnologien und des zirkulären Designs der Matratzen schaffen. Obwohl die Datenlage über Altmatratzen und deren Verwertung in Deutschland derzeit noch begrenzt sind und die hier präsentierten Ergebnisse von der gewählten Methodik abhängen, dient diese Masterarbeit als erste Grundlage für die weitere Entwicklung eines EPR-Systems für Matratzen in Deutschland.

    Description: Nicht nur für den Klimaschutz führt an der Wärmewende kein Weg vorbei. Mittelfristig wird sie auch die Heizkosten senken. Kurzfristig sind allerdings erhöhte Investitionen erforderlich, die für alle tragbar sein müssen. Ein wichtiges Instrument ist dabei die kommunale Wärmeplanung. Sie wird kommen und sie wird zu erheblichem Aufwand bei den kommunalen Gebietskörperschaften führen, aber den Bürgerinnen und Bürgern, Unternehmen und öffentlichen Einrichtungen auch Anleitung und Sicherheit für ihre Investitionen in zukunftsfähige Heizungssysteme bieten. Nach den bisherigen Planungen ist vorgesehen, dass seitens des Bundes ein Gesetz verabschiedet wird, welches die Länder verpflichten wird, flächendeckend eine kommunale Wärmeplanung zumindest für die mittleren und größeren Städte und Gemeinden vorzunehmen. Seitens der Länder wird diese Aufgabe dann an die Kommunen weitergegeben. Die Bundesländer Baden-Württemberg und Schleswig-Holstein haben bereits seit einiger Zeit Erfahrung mit diesem kommunalen Planungsinstrument. Der Gesetzentwurf auf Bundesebene wird noch für das zweite Quartal 2023 erwartet. Unabhängig davon sieht der Koalitionsvertrag der Landesregierung in Nordrhein-Westfalen vor, dass im laufenden Jahr 2023 der gesetzliche Ordnungsrahmen für die kommunale Wärmeplanung geschaffen wird. Der genaue Zeitplan steht somit noch nicht fest; klar ist aber, dass es in absehbarer Zeit zu einer Verpflichtung für die NRW-Kommunen kommen wird, solche Pläne zu erstellen. Es lohnt daher, sich bereits frühzeitig mit dem Thema zu befassen.

    Description: The original objectives for introducing Energy Performance Certificates (EPCs) were 1) to make energy performance transparent in the building market, as a measure of energy costs of using a building that a potential buyer or tenant would be interested in; and 2) to encourage energy efficiency renovation. However, the current implementation of EPC schemes in the Member States still shows significant challenges in achieving these two objectives. The recast of the EU Directive on the Overall Energy Performance of Buildings (EPBD) provides a chance to enhance both the usefulness and quality of EPCs and the EPC schemes overall. This document aims to inform both the debate on the recast of the EPBD and the enhancement of national EPC schemes in EU Member States. It presents the draft policy recommendations of the Horizon 2020 QualDeEPC project for making the EPBD and the national schemes more effective, particularly for deep renovation, and enhance their quality overall. The policy recommendations particularly target the link between EPCs and deep (energy) renovation1, while increasing the levels of ambition and convergence across the EU in terms of building renovation. Deep (energy) renovation is crucial for mitigating climate change and for energy security. The EPBD and all of its articles, as well as national EPC schemes, should aim to make deep (energy) renovation the default. This objective would be embedded and ensured in EPC schemes, if the policy recommendations provided in this document were adopted and implemented.

Konferenz der Vertragsparteien des Rahmenübereinkommens der Vereinten Nationen über Klimaänderungen (27th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), COP27) im ägyptischen Scharm El Sheikh zu Ende. Geplant war die Konferenz bis Freitag. Doch es gab viel zu diskutieren. Katastrophale Extremwetterereignisse wie die Überschwemmungen in Pakistan und historische Dürren in Europa unterstrichen auch dieses Jahr wieder die Bedeutung von ambitionierten klimapolitischen Entschlüssen. Auch der neueste Bericht des Weltklimarats (Intergovernmental Panel on Climate Change, IPCC) hatte erneut hervorgehoben, dass diese Ereignisse weiter eskalieren werden, je mehr die globale Erwärmung zunimmt.

    Description: At the next United Nations (UN) climate conference in the United Arab Emirates at the end of 2023, the first Global Stocktake (GST) of the Paris Agreement is due to conclude. The main goal of this process is to feed into a new round of Nationally Determined Contributions (NDCs) by Parties to the Agreement for 2035. In addition, the GST is aimed at identifying opportunities for strengthening international cooperation to achieve the Paris goals. The GST represents the first opportunity for Parties and other stakeholders to collectively highlight opportunities for international climate cooperation. Specifically, outcomes should plant the seeds for the development of concrete sectoral decarbonization roadmaps that could guide international cooperation in years to come.

    Description: This Wuppertal Paper analyses the energy transition models of Colombia and Germany. The emphasis of the exercise is on an analysis of options for the complete decarbonization of the energy system in Colombia as a Global South country. To this end, it analyses the current situation, projections, public policy and narratives, and contrasts it with Germany as one of the countries of the Global North with which Colombia has historically maintained energy trade relations and is currently collaborating in the exploration of energy alternatives for decarbonization. Detailed analysis of sectoral energy consumption in Colombia shows the sectors with the highest fossil energy consumption (in this order): transport (fuels), industry (gas, coal), electricity generation (gas, coal) and residential (gas). We show the projected increase in demand for fuels and electricity, and calculate the amount of electricity theoretically needed to substitute fossil sources in each sector. We estimate the total electricity required for decarbonization via sector coupling and derive a first estimation of the range of additional renewable energy capacities needed to supply this demand. We find that required capacities are expectedly large (56-110 GW), depending on decarbonization pathways, and that export capacity beyond national demand may be limited. Our analysis of the policy and scenario arena in both countries finds that Colombia is still lacking both sector-specific decarbonization strategies and an embedding in a systemic vision of a systemic energy transition. Germany has more advanced sector strategies and (national) systemic visions, but lacks embedding assumptions on energy imports in a global-system analysis, i.e. in the analysis of an energy transition in potential exporting countries like Colombia. We formulate requirements to close these gaps in our conclusions.
