    Description: Effective policies to mitigate climate change need to be accompanied by a socially just transition. Based on experiences of past and ongoing transition policies in coal regions in Europe and with indications to the specificity of framework conditions and challenges and to the potential effectiveness and transferability of approaches, this paper presents lessons learnt which can be inspirational for similar transitions in other coal regions and for transitions in other sectors.

    Description: This case study examined the structural change in the Ruhr area caused by the low international competitiveness of German hard coal mining over the period from the late 1950s to 2015. It analysed the structural change process and the structural policies implemented as a reaction to this process with the objective to make this knowledge available for future structural change processes in other (coal) regions by deploying various qualitative and quantitative methods of empirical social and economic research. A discourse analysis helped to recognise who supported which structural policy approaches and why - and thus gives indications of the possible relevance of experiences for other regions.

    Description: Dominant agricultural and food systems lead to continuous resource depletion and unacceptable environmental and social impacts. While current calls for changing agrifood systems are increasingly framed in the context of sustainability transitions, they rarely make an explicit link to transition studies to address these systemic challenges, nor do transition scholars sufficiently address agri-food systems, despite their global pertinence. From this viewpoint, we illustrate several gaps in the agri-food systems debate that sustainability transition studies could engage in. We propose four avenues for research in the next decade of transition research on agri-food systems: 1) Crossscale dynamics between coupled systems; 2) Social justice, equity and inclusion; 3) Sustainability transitions in low- and middle-income countries; 4) Cross-sectoral governance and system integration. We call for a decade of new transition research that moves beyond single-scale and sector perspectives toward more inclusive and integrated analyses of food system dynamics.

    Description: Technological breakthroughs and policy measures targeting energy efficiency and clean energy alone will not suffice to deliver Paris Agreement-compliant greenhouse gas emissions trajectories in the next decades. Strong cases have recently been made for acknowledging the decarbonisation potential lying in transforming linear economic models into closed-loop industrial ecosystems and in shifting lifestyle patterns towards this direction. This perspective highlights the research capacity needed to inform on the role and potential of the circular economy for climate change mitigation and to enhance the scientific capabilities to quantitatively explore their synergies and trade-offs. This begins with establishing conceptual and methodological bridges amongst the relevant and currently fragmented research communities, thereby allowing an interdisciplinary integration and assessment of circularity, decarbonisation, and sustainable development. Following similar calls for science in support of climate action, a transdisciplinary scientific agenda is needed to co-create the goals and scientific processes underpinning the transition pathways towards a circular, net-zero economy with representatives from policy, industry, and civil society. Here, it is argued that such integration of disciplines, methods, and communities can then lead to new and/or structurally enhanced quantitative systems models that better represent critical industrial value chains, consumption patterns, and mitigation technologies. This will be a crucial advancement towards assessing the material implications of, and the contribution of enhanced circularity performance to, mitigation pathways that are compatible with the temperature goals of the Paris Agreement and the transition to a circular economy.

    Description: The idea for the Green Recovery Tracker was born in spring 2020 when governments started making announcements on economic Corona recovery measures. From a climate and resilience perspective it is key that those recovery packages, investments and subsidies are in line with long-term climate and sustainability targets. Thus, recovery packages should not only boost the economy in the short-term, but also strike the path to a just transition towards climate neutrality. Against this background, Wuppertal Institute and E3G have launched the Green Recovery Tracker project in late summer 2020 to shed light on the following questions: What can be considered an effective green recovery? What are good examples, which can be used as an inspiration for recovery programs aiming to support sustainable development? Where do the individual Member States stand with respect to aligning their recovery activities with the climate policy agenda? In this report, you will find our Methodology as well our Policy Briefing highlighting our key takeaways of our country and sectoral analyses. It further includes a section on "What can we learn from our experience with the Green Recovery Tracker?". The briefing concludes with a "Guidance for future funding programs and achieving climate targets overall".

    Description: By applying a phase model for the renewables-based energy transition in the MENA countries to Israel, the study provides a guiding vision to support the strategy development and steering of the energy transition process. The transition towards a renewable-based energy system can reduce import dependencies and increase the energy security in Israel. Key issues that need to be tackled in order to advance the energy transition in Israel are the expansion of flexibility options, discussion on the long-term role of natural gas, increasing participation and awareness, and exploring the future role of power-to-X in the energy system.

    Description: A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy transition in MENA countries has been developed and applied to the country case of Iraq. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers. The transition towards renewable energies is still at a very early stage in Iraq. Despite the drop in renewable technology costs over the last decade and the increasing deployment of renewables in the MENA region, the pathway towards renewable energies seems to be challenging for Iraq. This is attributable to the country's political instability and the dominant economic role played by the fossil fuel sector. The most pressing concern for Iraq's electricity sector is the need to secure a constant electricity supply. At operational level, Iraq's electricity infrastructure requires significant investment to rebuilt, retro-fit and expand its overall capacity and to improve efficiencies. Yet, the need to rebuild the energy system after the war and the subsequent violent conflicts could offer an opportunity for a transition towards renewables that would benefit Iraq in the short term and also provide a long-term economic development perspective. To take advantage of this opportunity, Iraq needs to improve the framework conditions for renewable energies and raise awareness about the benefits it offers. Renewable energy regulations need to be introduced, market development supported, a realistic timeframe for the transition process established and an appropriate and reliable legal framework developed. The results of the analysis along the transition phase model towards 100% renewables are intended to stimulate and support the discussion about Iraq's future energy system by providing an overarching guiding vision for the energy transition and the development of appropriate policy strategies.

    Description: A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy transition in MENA countries has been developed and applied to the country case of Egypt. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers. Egypt, with its abundant solar and wind energy potential, has excellent preconditions to embark on the pathway towards a 100% renewable energy system. The country has successfully taken its first steps in this direction by attracting international finance and implementing several large-scale solar and wind projects. Yet, while Egypt has made significant progress, increased efforts are still required if the country aims to proceed towards a fully renewables-based system. The stronger system integration of renewable energies requires, for example, an alignment of regulations for the electricity, mobility and heat sectors. In this context, Egypt would be well advised to develop and implement an overall strategy for the energy transition that includes not only electricity generation but all sectors. By placing a stronger focus on renewable energy, also to decarbonise the industrial sector, Egypt, as Africa's second most industrialised country, could seize the opportunity for economic development within a decarbonising global economy. The results of the analysis along the transition phase model towards 100% renewable energy are intended to stimulate and support the discussion on Egypt's future energy system by providing an overarching guiding vision for the energy transition and the development of appropriate policies.

    Description: With the move to a hydrogen-based primary steel production envisioned for the near future in Europe, existing regional industrial clusters loose major assets. Such a restructuring of industries may result in a new geographical distribution of the steel industry and also to another quality of vertical integration at sites. Both implications could turn out as drivers or barriers to invest in new technologies and are thus important in respect to vertical integration of sites and to regional policy. This paper describes an approach to model production stock invest for the steel industries in North-Western Europe. Current spatial structures are reproduced with capacity, technical and energy efficiency data on the level of single facilities like blast furnaces. With the model developed both investments in specific technologies and at specific production sites can be modelled. The model is used to simulate different possible future scenarios. The case with a clear move to hydrogen-based production is compared to a reference scenario without technological shift. The scenarios show that existing trends like movement of production to the coast may be accelerated by the new technology but that sites in the hinterland can also adapt to a hydrogen economy. Possible effects of business cycles or a circular economy on regional value chains are explored with a Monte-Carlo analysis.

    Description: Direct Air Capture (DAC) is increasingly being discussed as a possibility to limit climate change. In this study, a possible rollout of the DAC technology at German coastal areas is analysed based on an existing climate neutrality scenario. For the year 2045 the resulting costs as well as land, water and energy consumption are examined. It is concluded that a realization of the DAC technology in Germany might be possible from a technical point of view. However, there is a high demand for land and energy. Since a rollout is needed to start in 20 years at the latest, the required discussion and evaluation should be initiated as quickly as possible.

    Description: Model-based scenario analyses of future energy systems often come to deviating results and conclusions when different models are used. This may be caused by heterogeneous input data and by inherent differences in model formulations. The representation of technologies for the conversion, storage, use, and transport of energy is usually stylized in comprehensive system models in order to limit the size of the mathematical problem, and may substantially differ between models. This paper presents a systematic comparison of nine power sector models with sector coupling. We analyze the impact of differences in the representation of technologies, optimization approaches, and further model features on model outcomes. The comparison uses fully harmonized input data and highly simplified system configurations to isolate and quantify model-specific effects. We identify structural differences in terms of the optimization approach between the models. Furthermore, we find substantial differences in technology modeling primarily for battery electric vehicles, reservoir hydro power, power transmission, and demand response. These depend largely on the specific focus of the models. In model analyses where these technologies are a relevant factor, it is therefore important to be aware of potential effects of the chosen modeling approach. For the detailed analysis of the effect of individual differences in technology modeling and model features, the chosen approach of highly simplified test cases is suitable, as it allows to isolate the effects of model-specific differences on results. However, it strongly limits the model's degrees of freedom, which reduces its suitability for the evaluation of fundamentally different modeling approaches.

    Description: The construction sector is the second largest area for the application for plastics. Due to the long life times of construction products, the implementation of the circular economy faces its own challenges. To investigate this challenge, the study covers a market study for Germany, voluntary take-back and recycling schemes of construction products, as well as the use of plastic recyclates in construction products. In addition, plastic packaging of construction products is covered. Opportunities and barriers to the use of recycled plastics in construction products are derived from the intersection of available technologies, recyclate supply, and technical requirements for construction products. The report concludes with recommendations to various stakeholders on how to promote the use of recyclates in construction products and their packaging. Important points here are the introduction of a recyclate quota for films as construction product packaging and the description of recycling possibilities and recyclate content in the technical documentation of construction products.

    Description: A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy (RE) transition in the Middle East and North Africa (MENA) countries has been developed and applied to ten countries: Algeria, Egypt, Iraq, Israel, Jordan, Lebanon, Morocco, Palestine, Tunisia, and Yemen. This report synthesises the results of these ten studies. The analysis shows that the state of the energy sector in the MENA region varies from country to country, but some underlying trends are present in all countries. In the majority of countries, energy prices are subsidised, and energy markets are mostly not liberalised. The energy demand in all analysed countries is growing and most grid systems are poorly interconnected across borders. Still, the expansion of RE in the MENA region can benefit from significant global progress and cost reductions in RE technologies. Reducing greenhouse gas (GHG) emissions is not the only key driver for energy transition. In fact, the main motives for transition are that RE can help to meet growing demand, reduce dependence on imports, increase energy security, and provide opportunities for economic development. All countries studied have RE targets. While some countries are on track to meet these targets, others need to increase their efforts to expand renewable electricity generation in order to meet their goals. Strong progress has been made in countries with limited fossil energy resources, while in some countries that produce and export large amounts of fossil energy resources, the energy transition is progressing rather slowly.

To facilitate such understanding, a phase model for the renewable energy (RE) transition in MENA countries has been developed and applied to the country case of Yemen. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers. The transition towards REs is still at a quite early stage in Yemen. The military conflict has prevented the implementation of most of the planned large-scale renewable projects. The political instability, the high dependence on fossil fuels, and poor administrative performance are the most pressing concerns for Yemen's electricity sector. At an operational level, Yemen requires a total retrofit of the electricity infrastructure and needs to expand its overall capacity while improving its efficiencies. Despite these challenges, rebuilding the energy system after the political turmoil and the subsequent violent conflicts could offer Yemen the capability to transition towards renewables. This will provide short-term and long-term opportunities and avoid stranded investments in fossil-fuel capacities. The priority is to improve the framework conditions for RE in Yemen, starting with the development of a long-term strategy up to 2030 and beyond. Also, an appropriate and transparent legislation must be created. Furthermore, based on the legislation, clear regulations for REs must be introduced, and a realistic timeframe for expansion must be established in order to promote acceptance and market development on a large scale. The results of the analysis along the transition phase model towards 100% RE are intended to stimulate and support the discussion on Yemen's future energy system by providing an over-arching guiding vision for the energy transition and the development of appropriate policies.

    Description: A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy (RE) transition in the Middle East and North Africa (MENA) countries has been developed and applied to the country case of Lebanon. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers. Lebanon's energy transition towards REs stands at a very early stage of the first transformation phase. Although abundant solar and wind energy potential does exist, the pathway towards a 100% renewables energy seems very challenging for Lebanon, as a consequence of highly unstable political conditions. The most pressing concern for Lebanon's electricity sector is combating the country's fiscal imbalance, while providing secure and reliable electricity supply. At the operational level, Lebanon's grid network requires significant investments to rebuild, retrofit, and expand the overall capacity and energy efficiency improvements. The need to strengthen the energy system after the political turmoil of the civil war is likely to offer several long-term opportunities, such as developing the economy, reducing environmental pollution, and increasing the energy security. In order to move forward into the first phase, Lebanon needs to improve the framework conditions for REs and implement its visions. It needs to support the market development in a realistic timeframe, where structural reforms represent the highest priority. The results of the analysis along the transition phase model towards 100% renewables energy are intended to stimulate and support the discussion on Lebanon's future energy system by providing an overarching guiding vision for the energy transition and the development of appropriate policies.

    Description: Die Forschung der FVEE-Institute zum Einsatz von klimaneutral erzeugtem Wasserstoff in der Industrie deckt sowohl technische Aspekte für einzelne Prozesse ab als auch systemanalytische Betrachtungen, die die Einsatzmöglichkeiten von Wasserstoff am einzelnen Standort oder für bestimmte Branchen in Deutschland bzw. Europa untersuchen. Die Motivation zum Einsatz von Wasserstoff ergibt sich aus drei Gründen: 1. In der stofflichen Verwendung wird Wasserstoff als Molekül benötigt und kann deshalb auch nicht durch andere Energieträger substituiert werden. So wird Wasserstoff bereits heute in großen Mengen in der Ammoniaksynthese (Haber-Bosch-Verfahren) sowie in den Raffinerien benötigt. 2. Eine weitere Verwendungsart für Wasserstoff ergibt sich aus seiner Fähigkeit, Sauerstoff aus Eisenerz chemisch zu binden. Beim Einsatz in Direktreduktionsanlagen kann Wasserstoff als Reduktionsmittel eingesetzt werden, um Eisenerz zu Roheisen zu reduzieren. 3. Als dritte Option gerät die energetische Verwendung von Wasserstoff in der Industrie zunehmend in den Fokus der energiepolitischen Debatten. Hier steht Wasserstoff in einem klimaneutralen System direkt in Konkurrenz zu anderen Energieträgern wie Strom und Biomasse.

    Description: Das Energiesystem der Zukunft wird stark durch Elektrifizierung geprägt sein. Für die Langzeitspeicherung von Energie sowie für Bereiche, die sich nicht sinnvoll durch Strom defossilieren lassen, werden aber auch in Zukunft chemische Energieträger benötigt. Das Ziel der Klimaneutralität bedingt, dass diese Energieträger vollständig emissionsfrei aus erneuerbaren Energien (EE) hergestellt werden. Diese grünen Energieträger sind transportier- und handelbar, sodass sich ein internationaler Markt für grünen Wasserstoff und seine Folgeprodukte entwickeln wird. Derzeit gibt es diesen Markt noch nicht. Grüner Wasserstoff ist preislich noch nicht konkurrenzfähig gegenüber fossilen Brennstoffen. Den größten Anteil am Wasserstoffpreis haben die Kosten für die Elektrolyseanlage sowie die Kosten für die Strombereitstellung. Die besten Bedingungen für die Wasserstoffproduktion bieten daher EE-Standorte und Technologien mit hohen Volllaststundenzahlen, an denen auch der Elektrolyseur bei wenig EE-Abregelung auf viele Betriebsstunden kommt.

    Description: Deutschland soll bis 2045 klimaneutral werden. So steht es im verschärften Klimaschutzgesetz, das im Juni 2021 vom Bundestag verabschiedet wurde. Die deutsche Industrie verursacht derzeit knapp ein Viertel der Treibhausgasemissionen, etwa ein Drittel davon entfällt auf die Eisen- und Stahlproduktion. Um das Klimaziel zu erreichen, müssen somit große CO2-Einsparungen in der Stahlindustrie realisiert werden.

    Description: When dealing with the Great Transformation towards a sustainable world (WBGU 2011), one defining factor is the stark contradiction in the availability of knowledge: While there is almost unlimited knowledge on many technical and economic aspects of the sustainability transformation, while in some way all the tools are available and we, in theory, know exactly how to use them, there is a lack of action at all levels. If we assume that in principle a majority of decision-makers has understood the necessity to act, this ultimately points to a lack of knowledge on how major transformations can be triggered. To use a common distinction, we have solid knowledge of the systems at play, we know the targets society should be heading for, and these targets have been globally and politically agreed to, but our knowledge on transformations, while growing, is obviously lacking. While this is true for all forms of knowledge to some extent, especially transformation knowledge requires more than just disciplinary or interdisciplinary research because it depends on transdisciplinary approaches that integrate the knowledge of practitioners from politics, administration, civil society and business.

    Description: Kreislaufwirtschaft beschreibt ein Konzept, bei dem Abfall und Verschmutzung nicht per se im Wirtschaftsdesign vorausgesetzt werden. Sie greift damit die Ursachen der derzeit global dringlichsten Querschnittsthemen nachhaltiger Entwicklung mit dem Ziel auf, verantwortungsvoll mit Ressourcen, Wertstoffen, Produkten und der Umwelt umzugehen. Entstehen soll damit eine Welt, in der kein Müll produziert wird. Das Konzept verfolgt dabei einen multidimensionalen Ansatz und umfasst alle Wirtschaftsbereiche - von der Ressourcengewinnung über die Produktion, die Lagerung und den Konsum bis hin zur Entsorgung beziehungsweise zum Recycling. Mithilfe der Kreislaufwirtschaft können multiple Nachhaltigkeitsziele der Agenda 2030 schneller erreicht werden, weshalb sie als ein zentraler Baustein nachhaltiger Entwicklung gilt.

    Description: Die vorliegende Darstellung vergleicht fünf ausgewählte aktuelle Klimaschutzszenarien für Deutschland in Hinblick auf zentrale Entwicklungen im Energiesystem bis Mitte des Jahrhunderts. Die fünf Szenarien sind zwischen April und Oktober 2021 erschienen und beschreiben unterschiedliche Pfade, wie Klimaneutralität in Deutschland bis zum Jahr 2045 bzw. 2050 erreicht werden könnte. Die Szenarien wurden von verschiedenen Organisationen in Auftrag gegeben und von unterschiedlichen wissenschaftlichen Instituten bzw. Beratungsunternehmen erarbeitet. Im vorliegenden Vergleich werden verschiedene Kenngrößen des Energiesystems auf Energieangebots- sowie Energienachfrageseite betrachtet. Die Gegenüberstellung der jeweiligen Entwicklungen in den Szenarien soll aufzeigen, in welchen Bereichen die Studien auf dem Weg zur Klimaneutralität ähnliche Entwicklungen vorsehen und in welchen Bereichen es derzeit noch deutlich abweichende Vorstellungen über die genaue Ausgestaltung der Energiesystemtransformation gibt.

    Description: On the basis of a literature research, this subtask develops a conceptional framework for a common understanding of CE within the project team and for the following work packages and tasks. After a brief introduction into the objectives and the context of a circular economy, a more elaborated look into the necessity of an explicit understanding of CE, the objectives, the spatial perspective of CE and the specific challenges within the CICERONE context will be done, in order to develop a basis for a common understanding within the project context. Circular economy can and has to be understood as an (eco-)innovation agenda. Therefore, the paper investigates the role policy has to play to support innovation for a CE transition, for creating the framework conditions and why CE has also to be build from the ground up. Finally, the paper looks from two perspectives at emerging trends and business models in a CE to sketch next steps towards the transition in a selection of central sectors. Conclusions are drawn on the basis of the insights gained by the preceding chapters.

    Description: Um einen angemessenen Beitrag zu einer Begrenzung des weltweiten Temperaturanstiegs auf 1,5 Grad Celsius zu leisten, müsste Deutschland und damit auch der Gebäudesektor schon bis 2035 treibhausgasneutral sein. Greenpeace hat daher das Wuppertal Institut beauftragt, ein Sechs-Punkte-Sofortprogramm für erneuerbare Wärme und effiziente Gebäude zu erarbeiten, mit dem dieses Ziel erreichbar wird. Das Sofortprogramm sieht vor, dass in drei zentralen Bereichen jeweils eine ordnungsrechtliche Maßnahme mit einer spezifischen, dazu passenden finanziellen Fördermaßnahme kombiniert wird: 1) Ausstiegsgesetz für fossile Heizungen und Förderung für elektrische Wärmepumpen und Solarthermie. 2) Pflicht und Förderung für die energetische Sanierung ineffizienter Gebäude mit ökologischen Kriterien. 3) Gesetz mit Zielen sowie förderlichen Bestimmungen und dazu passende Förderung für Erneuerbare-Wärmenetze: Ausbau und Umstieg auf grüne Wärmeerzeugung. So erhöht das Sofortprogramm die energetische Sanierungsrate auf drei bis vier Prozent pro Jahr und führt dazu, dass schon 2035 fast zwei Drittel der Gebäude mit Wärmepumpen und etwa ein Viertel mit Nah- und Fernwärme aus erneuerbaren Energien beheizt werden und ein Drittel zusätzlich mit thermischen Solaranlagen ausgestattet wird.

    Description: The EU aims to become the first climate neutral continent. To achieve this goal, the industry sector needs to reduce its GHG emissions to net zero or at least close to net zero. This is a particularly challenging task due to the high energy demand especially of primary materials production and the little potential to reduce this energy intensity when switching to other production processes based on electricity or hydrogen. In order to identify robust strategies for achieving a net-zero-compatible industry sector, the paper at hand analyses the transformation of the industry sector as described by a number of recent climate neutrality scenarios for Germany. Apart from overall industry, a focus is set on the sectors of steel, chemicals and cement. The analysed scenarios show very deep GHG emission reductions in industry and they appear to be techno-economically feasible by the mid of the century, without relying on offsets or on shifts from domestic production to imports. The scenarios agree on a suite of core strategies to achieve this, such as direct and indirect electrification, energy efficiency and recycling as well as new technological routes in steel making and cement. The scenarios differ, however, regarding the future mix of electricity, hydrogen and biomass and regarding the future relevance of domestic production of basic chemicals.

    Description: Im Auftrag der Fraktion BÜNDNIS 90/DIE GRÜNEN im Bayerischen Landtag haben Forschende des Wuppertal Instituts wissenschaftlich überprüft, wie viele Treibhausgas-Emissionen im Jahr 2030 bestimmte landespolitische Klimaschutz-Maßnahmen potenziell einsparen können. Die vorliegende Studie schätzt dabei sowohl die Effekte der Maßnahmen auf die insgesamt verursachten Treibhausgas-Emissionen (Verursacherprinzip) als auch auf die in Bayern selbst statistisch erfassten Emissionen (Quellenprinzip) ab. Die Maßnahmen adressieren die folgenden fünf Bereiche: 1) Gebäude und Verkehrsmittel im Besitz der öffentlichen Hand. 2) Ausbau der Windenergie und Photovoltaik. 3) Energieeffizienz im Gebäudesektor. 4) Energieeffizienz und Verkehrsverlagerung im Transportsektor. 5) Landwirtschaft und Landnutzung. Zwei Beispiele der untersuchten Maßnahmen sind Verbesserungen der Rahmenbedingungen für den Bau neuer Windenergieanlagen und eine stärkere Nutzung des industriellen Abwärmepotenzials.

    Description: More and more cities are setting themselves ambitious climate protection targets, including CO2 neutrality. Schools are important institutions of cities and therefore they have to play a central role in achieving this goal. With the investment backlog building up and pressure from the Friday for Future movement increasing, the Wuppertal Institute and Büro Ö-quadrat have initiated the project Schools4Future, aiming to support secondary schools to become climate-neutral. In cooperation with secondary school students and teachers, the project team evaluated the existing situation of the participating schools and developed GHG-balances and feasible climate protection concepts. For this purpose, an Excel-based carbon footprint (CF) assessment tool for schools has been developed which is freely available. The tool covers all important emission areas, including heating energy, electricity use, travel to and from schools, school trips, the school canteen and paper consumption. The students were found capable to conduct the CF assessment with the guidance of the teacher, information materials and support of the researchers. So far, six pilot schools have completed their CF assessment with emissions ranging between 335 and 944 kg CO2 per person. In this paper we present the tool and compare the CF assessment of some schools. We further elaborate on how the tool and project has increased the climate awareness and self-efficacy of students and even stimulated measures by the school board.

    Description: Auch die thermische Abfallbehandlung in Deutschland kann zu einem Baustein des klimaneutralen Wirtschaftens werden. Allerdings sind dafür noch verschiedene Voraussetzungen zu schaffen. Technisch sind neben den bereits bekannten weitere innovative Verfahren in der Entwicklung; nicht zu vernachlässigen ist zudem die anspruchsvolle Aufgabe des CO2-Handlings. Hier ist zum einen der Aufbau der benötigten Infrastruktur zu nennen. In Bezug auf die Nutzung des abgetrennten CO2 ist auch die Industrie gefragt, um sektorübergreifende, klimafreundliche Use-Cases und Geschäftsmodelle rund um CCU und die weitmöglichste Schließung von Kohlenstoffkreisläufen zu entwickeln. Entsprechende Regularien und Marktanreize sind politisch zu setzen.

    Description: Die Bauindustrie und die Immobilienwirtschaft gehören zu den ressourcenintensivsten Sektoren der heutigen Zeit. Jährlich werden Millionen Tonnen mineralischer Rohstoffe, Metalle, Holz, Kunststoff, Glas und anderen Materialien für die Erstellung und Sanierung von Wohngebäuden genutzt. Auch die Herstellung von Zement ist als ein Hauptbestandteil von Beton mit enormen Treibhausgas-Emissionen verbunden. Der Neubau, die Sanierung und der Abriss von Gebäuden sorgt zudem für große Mengen Bau- und Abbruchabfälle. Für die Immobilienwirtschaft stellt sich daher die Frage, wie sie ihren Gebäudebestand ökologisch optimieren kann. Doch was wiegt ökologisch stärker: der Mehrbedarf an Rohstoffen und die anfallenden Abfallmengen bei Abriss und Neubau oder die ressourcenintensivere Nutzungsphase von sanierten Bestandsgebäuden, wenn deren energetische Qualität niedriger ist als bei Neubauten? Vor diesem Hintergrund hat das Wohnungsunternehmen LEG das Wuppertal Institut beauftragt, anhand von drei exemplarischen LEG-Gebäuden die energetische Gebäudesanierungen im Vergleich zur Alternative eines Abrisses und Neubaus ökologisch zu bewerten. Im Fokus der Untersuchung standen dabei der Primärenergieverbrauch, die damit verbundenen Treibhausgas-Emissionen der Nutzungsphase sowie die gespeicherte Graue Energie der Gebäude und den hiermit verbundenen Treibhausgas-Emissionen. Nun liegen die Studienergebnisse vor: Wird der gesamte Lebenszyklus berücksichtigt, verursacht die energetische Sanierung nur die Hälfte der CO2-Fußabdrücke eines Neubaus. Um das Ziel zu erreichen, müsse der Weg zur Elektrifizierung von Heizsystemen noch beschleunigt und damit die Abhängigkeit von fossilen Energieträgern verringert werden. Zwar gleicht der Neubau das Ungleichgewicht zwischen Angebot und Nachfrage aus und hat damit einen sozialen Wert, eine Alternative zur Sanierung in Beständen ist er aus ökologischer Sicht allerdings nicht.

    Description: Impact chains are used in many different fields of research to depict the various impacts of an activity and to visualize the system in which this activity is embedded. Research has not yet conceptualized impact chains specifically for energy sufficiency policies. We develop such a concept based on current evaluation approaches and extend these by adding qualitative elements such as success factors and barriers. Furthermore, we offer two case studies in which we test this concept with the responsible climate action managers. We also describe options for integrating these impact chains into different types of energy models, which are key tools in policy consulting.

    Description: Die direkte Abscheidung von Kohlenstoffdioxid (CO2) aus der Luft, das sogenannte Direct Air Capture (DAC), wird vermehrt als eine der Möglichkeiten zur Reduzierung von Treibhausgasen und damit der Begrenzung der Klimaerwärmung diskutiert. Vorteilhaft gegenüber anderen technischen Ansätzen zur Entnahme von atmosphärischen CO2 (Negativemissionstechnologien) ist die genaue Planbarkeit, die geringen Auswirkungen auf die Umwelt und die Ausgabe von CO2 in Reinform. Das CO2 kann anschließend dauerhaft gespeichert (Direct Air Capture and Sequestration) oder zur Erzeugung von bspw. synthetischen Brennstoffen (Direct Air Carbon Capture and Utilization) in Power-to-X-Routen (PtX) genutzt werden. Ziel dieser Arbeit ist es, im Kontext der deutschen Klimaneutralitätsziele bis 2045 beispielhaft eine Auslegung von DAC-Anlagen in Deutschland zu untersuchen. Dabei werden die unterschiedlichen Ressourcenverbräuche (Energie, Wasser, Fläche) sowie Kosten und mögliche Einsparungen durch eine Abwärmenutzung dargestellt und verglichen. Dabei soll diese Arbeit zur Beantwortung der folgenden Forschungsfragen beitragen: Welche technologischen DAC-Ansätze sind für Deutschland realisierbar? Welche Mengen an CO2 müssen in Deutschland umgesetzt werden, um den Bedarf an Negativemission zu decken? Welcher Ressourcenverbrauch entsteht in Deutschland, wenn die betrachteten Fallstudien umgesetzt werden? Welchen Infrastrukturaufwand hat dies zur Folge? Ist eine Implementierung in den notwendigen Größenordnungen realisierbar, und welche Faktoren wirken hierbei beschränkend? Für eine systematische Analyse wurden die DAC-, die PtX- und die elektrischen und Wärmeenergieerzeugungsanlagen modular für die Jahre 2020, 2030, 2040 und 2045 aufbereitet. Die Bezugsgrößen wurden so gewählt, dass sie dem DAC-Modul entsprechen. In vier Fallstudien wurden mögliche Kombinationsmöglichkeiten und Implementierungspfade bis 2045 zusammengestellt, analysiert und diskutiert. Es zeigt sich, dass ein großskaliger Einsatz von DAC in Deutschland realisierbar ist. Zentrale Herausforderungen ergeben sich allerdings aus dem hohen Flächen- und Energiebedarf. Der Flächenbedarf resultiert dabei vor allem aus den flächenintensiven erneuerbaren Energieerzeugern. Mit Fokus auf ertragreiche Standorte sind Nord- und Süddeutschland, mit Blick auf ihr Wind- bzw. Sonnenpotenzial, als vielversprechend bei der Implementierung der DAC- Technologie einzustufen. Eine Implementierung der DAC-Technologie mit dem Ziel der dauerhaften CO2-Speicherung ist an norddeutschen Küstengebieten im Vergleich zu Süddeutschland vorteilhafter. Die Installation der DAC-Technologie in Kombination mit der PtX-Route wird aufgrund des hohen elektrischen Energiebedarfs in Deutschland als nicht realisierbar eingeschätzt.

    Description: Das Wohnen in Deutschland wird schon seit einigen Jahren durch zwei bedeutende Entwicklungstendenzen bestimmt: Zum einen sinkt die durchschnittliche Haushaltsgröße, zum anderen vergrößert sich die mittlere Pro-Kopf-Wohnfläche. Infolgedessen steigt die Wohnraumnachfrage deutlich an, was besonders im urbanen Raum zu höheren Mieten und ungleichen Verteilungsprozessen des Wohnungsbestandes führt. Bislang ist dieser zunehmenden Nachfrage nach Wohnraum vielerorts mit einer Ausweitung der Neubautätigkeit begegnet worden, was jedoch mit einem schnelleren Verbrauch wertvoller und begrenzter Bodenressourcen verbunden ist. Ein Konzept, das erst seit Kurzem als mögliche Antwort auf die aktuellen sozialen und ökologischen Herausforderungen des Wohnens diskutiert wird, ist das sogenannte suffiziente Wohnen. Dabei geht es um die grundlegende Frage, wie viel Wohnfläche es braucht, um die jeweiligen Bedürfnisse eines Haushaltes angemessen befriedigen zu können und wie durch eine bessere Nutzung des vorhandenen Baubestandes auf eine Änderung dieser Bedürfnisse reagiert werden kann. Suffiziente Wohnkonzepte zielen somit sowohl auf die Berücksichtigung individueller Wohnraumbedarfe als auch auf die Vermeidung weiterer Flächenversiegelung. Diese Masterarbeit möchte das Potential des suffizienten Wohnens im Kontext der aktuellen gesellschaftlichen, ökologischen und wohnungspolitischen Herausforderungen hervorheben. In diesem Zusammenhang spielt die Betrachtung sich verändernder Wohnraumbedarfe im Lebensverlauf von Personen eine zentrale Rolle, da es an bestimmten Wendepunkten häufig zu einer subjektiven Unter- oder Überversorgung mit Wohnfläche kommt. Mittels einer hierarchisch-agglomerativen Clusteranalyse und der repräsentativen LebensRäume - Bevölkerungsumfrage des BBSR werden insgesamt acht Wohntypen identifiziert, die sich je nach Lebensverlaufsphase und Wohnsituation unterscheiden. Dabei wird neben relevanten Umbrüchen in der Wohnbiographie von Personen auch die herausragende Bedeutung von Wohneigentum für die durchschnittlichen Pro-Kopf-Wohnflächen in den einzelnen Clustern deutlich. In Bezug auf die Förderung des suffizienten Wohnens in Deutschland lassen sich zwei zentrale Analyseergebnisse formulieren. Zum einen eröffnen der Auszug der Kinder, die Verrentung sowie die Verwitwung wichtige Möglichkeitsräume für die Veränderung von Wohnsituationen. Zum anderen gilt es, den Einfluss des Wohneigentums als Chance zu begreifen und durch Veränderungen der Bestandsimmobilie eine suffizientere Art des Wohnens zu ermöglichen.

    Description: This thesis conceptualizes the school as a socio-technical system, in which change towards sustainable development and a transition towards more climate awareness are necessary. The multi-level perspective (MLP) framework is applied to the German school system and to climate protection projects (CPPs) as examples of niche activities integrating climate protection (CP) in the school. The thesis utilizes the analytical levels of the MLP (landscape, regime, and niche) and the concept of regulative, cognitive, and normative rules and addresses the question: How do actors in CPPs perceive drivers and barriers for transitioning towards more climate awareness in the German school system? The data were collected through expert interviews and analyzed by conducting a qualitative content analysis. The results show that the German school system is characterized by an inherent rigidity, deep-set normative role dynamics, and an unappreciated role of schools in society. They also highlight the importance of public pressure, strategic CP orientation, and hands-on approaches. CPPs can be a driving force for this in individual schools, but, overall, CP needs to be addressed more systematically in the school and more substantial efforts and reforms are necessary. Highly motivated niche actors play an important role and represent key drivers for such developments. This thesis reveals the complex and systemic nature of the challenges the German school system is faced with. It highlights the difficulties of integrating CP and the importance of substantial and transformative political action. The thesis demonstrates the crucial need to recognize the significance of schools and their actors for society and to integrate new methods and approaches into the school. This thesis also contributes to the body of literature on socio-technical systems and sustainability transitions. It offers an operationalization of the MLP and reveals strengths and limits as well as future research outlooks.

    Stockholm : European Council for an Energy Efficient Economy
    Publication Date: 2022-08-23
    Description: The Fit for 55 package stipulates a fair, competitive and green transition by 2030 and beyond. As part of this, increasing attention is given to the decarbonisation of the building stock: only 1 % of buildings in Europe are retrofitted each year, a number which must double if the EU is to meet its 2050 targets. Significant energy efficiency investments are needed, whilst the planned expansion of the EU-ETS to the building sector in 2026 will likely pass the carbon cost onto the consumer. This will increase the cost burden placed on low-income households, exacerbating energy poverty, if these two strategies are not counterbalanced by adequate policies and support mechanisms. The European Private Rented Sector (PRS) is often side-lined by policymakers when implementing energy efficiency policies to tackle energy poverty. As many as 1 in 10 Europeans spend 40 % or more of their income on housing costs, with those in the PRS struggling with energy-related problems, such as poor energy efficiency and maintenance, to a much greater degree than the general population. Understanding these challenges and creating targeted policies is of critical scientific and policy importance. To date, a pan-European policy on how to address energy poverty and energy efficiency improvements in the PRS is lacking; current European Union instruments to address such issues (including the Fit for 55, and the Clean Energy Package that preceded it) lack a dedicated approach towards the complex structural issues embedded in the European PRS. What is more, there is a limited understanding of the character of energy poverty in such residential dwellings, as well as policies to address energy injustices. We therefore examine current and historical disparities in energy poverty between the EU's PRS tenants and the general population by analysing a variety of quantitative indicators which reflect different dimensions of energy poverty. We then take stock of the policy landscape, identifying energy efficiency policies tailored to alleviate energy poverty in the PRS and common challenges. We subsequently interrogate possible solutions, drawing on existing good practice policies. In so doing, we aim to reduce the sector's political invisibility by addressing the lack of disaggregated, targeted data and dismantling barriers that currently lead to the PRS being disproportionately affected by energy poverty.

    Description: Variations in quantity, quality and time availability of input materials pose a major risk to circular supply chains (CSC) and require new models for creating and evaluating adaptive and resilient CSC in the circular economy (CE). This can be achieved through consistent modelling of the overarching relationship between resource input- and output streams, without neglecting the associated risks. The model proposed below consists of five components based on five resilience requirements for supply-chains (SCs). It provides a data-based recommended course of action for managers with a low entry-barrier. It consists of a CSC visualization, safety stock calculation, risk monitoring for each SC node, reporting logic, and a measurement catalogue. The inspiration for this model came from an innovative case study ("Zirkelmesser") in the metal processing industry, where secondary products and materials are used to produce new products. Here, the problem of maintaining the resource supply arose and led to resilience issues. The mentioned case study serves as an application example for the model application and contributes to making emerging circular supply chains predictable and more controllable, thus increasing their resilience.

    Description: Dengan semakin berkurangnya "anggaran karbon" atau carbon budget di seluruh dunia, berbagai negara sedang mencari solusi untuk mengurangi emisi gas rumah kaca. Karena produksi dan penggunaan batu bara dapat dikatakan sebagai salah satu penghasil emisi karbon yang sangat besar dan memicu perubahan iklim, oleh karena itu dapat diperkirakan bahwa wilayah penghasil batu bara akan sangat terdampak akibat transformasi energi dari sistem energi yang berbasis bahan bakar fosil menjadi energi terbarukan. Tantangan yang muncul tidak hanya di bidang produksi energi, perlindungan lingkungan, tetapi juga dalam aspek ekonomi dan sosial di kawasan kawasan batu bara yang tengah menghadapi transformasi - sering disebut dengan istilah "Transisi Berkeadilan". Para pengambil keputusan di wilayah penghasil batu bara, sangat membutuhkan alat pendukung untuk memulai langkah-langkah untuk mendiversifikasi ekonomi lokal yang disaat bersamaan juga mendukung pekerja dan masyarakat lokal. Transisi Berkeadilan ini membutuhkan perencanaan yang komprehensif, kebijakan baru dan penyesuaian serta keterlibatan semua pemangku kepentingan. Oleh karena itu, Wuppertal Institute merancang "Just Transition Toolbox" untuk memberikan dukungan bagi para praktisi di kawasan penghasil batu bara di seluruh dunia yang menggambarkan tantangan dan peluang dalam transisi berkelanjutan untuk audiens global. Toolbox Transisi Berkeadilan ini terdiri dari informasi tentang pengembangan strategi, rekomendasi untuk struktur tata kelola, mendorong lapangan kerja berkelanjutan, menunjukan pilihan teknologi dan menyoroti rehabilitasi lingkungan dan penggunaan kembali situs dan infrastruktur terkait batubara. Toolbox ini dikembangkan berdasarkan seperangkat alat yang dirancang oleh Wuppertal Institute melalui kerja sama dengan berbagai pemangku kepentingan atas inisiatif Uni Eropa untuk daerah-daerah kawasan Batubara yang berada dalam masa transisi. Toolbox ini juga menampilkan pelajaran yang diambil dari kawasan batu bara mitra SPIPA seperti India, Indonesia, Afrika Selatan, Jepang, Korea Selatan, Kanada, dan Amerika Serikat. Akronim SPIPA adalah kependekan dari "Kemitraan Strategis untuk Implementasi Perjanjian Persetujuan Paris" pada program UE-BMU yang dibiayai bersama oleh GIZ.

    Description: A medida que el presupuesto mundial de carbono disminuye rápidamente, los países de todo el mundo buscan soluciones para limitar las emisiones de gases de efecto invernadero. Dado que la producción y el uso del carbón son algunos de los procesos más intensivos en emisiones carbono, es previsible que las regiones que producen carbón se vean especialmente afectadas por las consecuencias de una transformación hacia la neutralidad climática. Estas regiones se enfrentan a retos en el ámbito de la producción de energía y la protección del medio ambiente, pero también a retos económicos y sociales, que se engloban en la necesidad de una "transición justa". Los responsables de la toma de decisiones en las regiones dependientes de la producción de carbón necesitan urgentemente herramientas de apoyo que ayuden a poner en marcha medidas para diversificar las economías locales y, al mismo tiempo, apoyar a los trabajadores y las comunidades locales. Wuppertal Institute busca apoyar a las regiones carboníferas de todo el mundo desarrollando una caja de herramientas para la transición justa, que ilustra los retos y las oportunidades de una transición sostenible para un público global. La caja de herramientas incluye recomendaciones para el desarrollo de estrategias y estructuras de gobernanza, líneas guía para la creación de empleo sostenible, el desarrollo de alternativas tecnológicas, la rehabilitación medioambiental y la reutilización de infraestructuras relacionados con el carbón. La caja de herramientas se basa parte del trabajo de Wuppertal Institute dentro de la Iniciativa de la UE para las Regiones Carboníferas en Transición y tiene en cuenta las circunstancias específicas de los países socios de la SPIPA: India, Indonesia, Sudáfrica, Japón, Corea del Sur, Canadá y Estados Unidos. El acrónimo SPIPA es la abreviatura de "Asociaciones Estratégicas para la Aplicación del Acuerdo de París", un programa UE-BMU cofinanciado por la GIZ.

    Description: Die Bundesrepublik Deutschland hat sich zum Ziel gesetzt, bis 2045 klimaneutral zu werden. Das kann nur funktionieren, wenn fossile Rohstoffe durch erneuerbare Energien ersetzt werden - insbesondere in den Bereichen Industrie und Verkehr. Ein wesentlicher Baustein in diesem Transformationsprozess ist die Errichtung einer Wasserstoffwirtschaft, innerhalb derer Strom aus erneuerbaren Energien in grünen Wasserstoff umgewandelt und dieser als Energieträger vor allem in den Bereichen Industrie und Verkehr angewendet wird.

    Description: Food production is responsible for approximately 17% of Germany's greenhouse gas (GHG) emissions. After retail, out-of-home catering is the second largest food sales channel in Germany. A variety of means on both the supply and demand side are necessary to stimulate, facilitate and encourage a more sustainable development and minimise GHG emissions in this sector. Nudges are one of these. This paper's focus lies on the demand side. Set in real-world laboratories, we use a standardised empirical approach to compare different nudging interventions belonging to the area of physical environment and consumers’ choice making process. We compare the effects of the same intervention across different settings and the effect of different, sequential nudging interventions in the same setting. Data was collected in eight workplace and school cafeterias in Germany over two project iterations (2016/2017; 2019/2020). A similar intervention design was applied. Comparability was assured by a harmonised menu. The first project iteration revealed that only one nudge (top menu position, +22.5%) led to significant increases in sustainable food choices, while results from the second iteration showed that all nudge interventions (best counter position, +11.6%; top menu position, +6,9%; label plus information, +15.9%) positively influenced consumer choice. Possible explanations such as the stricter compliance to the experimental design in the cafeterias but also societal developments such as the appearance of the Fridays for Future movement are discussed. As results vary between specific locations and settings, our findings suggest that nudges need to be adjusted to situational conditions for achieving highest efficacy.

    Description: This article enriches the existing literature on the importance and role of the social sciences and humanities (SSH) in renewable energy sources research by providing a novel approach to instigating the future research agenda in this field. Employing a series of in-depth interviews, deliberative focus group workshops and a systematic horizon scanning process, which utilised the expert knowledge of 85 researchers from the field with diverse disciplinary backgrounds and expertise, the paper develops a set of 100 priority questions for future research within SSH scholarship on renewable energy sources. These questions were aggregated into four main directions: (i) deep transformations and connections to the broader economic system (i.e. radical ways of (re)arranging socio-technical, political and economic relations), (ii) cultural and geographical diversity (i.e. contextual cultural, historical, political and socio-economic factors influencing citizen support for energy transitions), (iii) complexifying energy governance (i.e. understanding energy systems from a systems dynamics perspective) and (iv) shifting from instrumental acceptance to value-based objectives (i.e. public support for energy transitions as a normative notion linked to trust-building and citizen engagement). While this agenda is not intended to be—and cannot be—exhaustive or exclusive, we argue that it advances the understanding of SSH research on renewable energy sources and may have important value in the prioritisation of SSH themes needed to enrich dialogues between policymakers, funding institutions and researchers. SSH scholarship should not be treated as instrumental to other research on renewable energy but as intrinsic and of the same hierarchical importance.

    Description: Which of Pope Francis' countless appearances will posterity consider truly iconic? Probably neither his journey to the shipwrecked in Lampedusa nor his encounter with the indigenous peoples of the Amazon, although both are characteristic of the pontificate - rather, it will be his appearance in the deserted St. Peter's Square during the coronavirus pandemic. A single figure in white, alone, laboriously climbing the steps to St. Peter's Basilica, then offering the Urbi et Orbi blessing with the monstrance - that image will be in the history books. This view undoubtedly thrives on contrast: the image of the Pope standing alone in the rain at nightfall in contrast to the image familiar to television viewers from all over the world where the Pope appears in St Peter's Square amidst the cheering of tens or hundreds of thousands under Bernini's colonnades. And then, in March 2020, a formidable showing of vulnerability that touched even non-believers.

Zehn Prozent der Menschheit verursachen die Hälfte der Emissionen der gesamten Weltbevölkerung. In der Enzyklika "Fratelli tutti" widmet sich Papst Franziskus dem Gedanken der Brüderlichkeit und plädiert für eine gerechte und geschwisterliche Welt. Wolfgang Sachs führt diesen Gedanken weiter und überträgt ihn auf das Machtverhältnis Mensch und Natur. Sein Beitrag verbindet die christlichen Leitgedanken des päpstlichen Lehrschreibens mit aktuellen Problematiken und er formuliert damit eine wichtige Leitfrage: Wie kann aus kollektivem Kontrollverlust wieder gemeinschaftliches Handlungspotenzial werden?

    Description: As the worldwide remaining carbon budget decreases rapidly, countries across the globe are searching for solutions to limit greenhouse gas emissions. As the production and use of coal is among the most carbon-intensive processes, it is foreseeable that coal regions will be particularly affected by the consequences of a transformation towards a climate-neutral economy and energy system. Challenges arise in the area of energy production, environmental protection, but also for economic and social aspects in the transforming regions - often coined with the term "Just Transition". For the decision makers in coal regions, there is an urgent need for support tools that help to kick off measures to diversify the local economies while at the same time supporting the local workers and communities. The Wuppertal Institute aims to support coal regions worldwide by developing a Just Transition Toolbox, which illustrates the challenges and opportunities of a sustainable transition for a global audience. It comprises information about strategy development, sets recommendations for governance structures, fostering sustainable employment, highlights technology options and sheds light on the environmental rehabilitation and repurposing of coal-related sites and infrastructure. The toolbox builds on the work of the Wuppertal Institute for the EU Initiative for Coal Regions in Transition and takes into account country-specific findings from the SPIPA-partner countries India, Indonesia, South Africa, Japan, South Korea, Canada and the USA. The acronym SPIPA is short for "Strategic Partnerships for the Implementation of the Paris Agreement" an EU-BMU programme co-financed by the GIZ.

    Description: Die nachhaltigkeitsorientierte Transformation von urbanen Räumen ist eine akute Herausforderung. In den letzten Jahren haben koproduktive, experimentelle, transdisziplinäre und häufig informelle Stadtwandelprojekte als Such- und Lösungsräume hohe Sichtbarkeit erlangt. Schlüsselakteure hierfür stellen - so die These - Verwaltungsvertreter:innen einer integrierten Stadtentwicklung und -planung, Wissenschaftler:innen einer transformativen Forschung sowie zivilgesellschaftliche Stadtmacher:innen dar. Die Autor:innen, verankert in diesen drei Gruppen, kritisieren die häufig nur situative Zusammenarbeit dieser drei Akteursgruppen. Ein Modell der Zusammenarbeit im Spannungsfeld zwischen Gemeinsamkeiten, jeweiligen Potentialen und herausfordernden Eigenlogiken der Akteurssysteme wird entwickelt. Darauf aufbauend wird vorgestellt, wie durch strategischen Trialog und reflexive Lernprozesse die Zusammenarbeit verbessert und die Wirksamkeit koproduktiven und experimentellen Stadtwandels erhöht werden kann.

    Description: Household food waste is determined by a complex set of routinized behaviors, and disruption of these routines may allow for a decrease in this vast amount of food waste. The current study examines such a disruption of household routines: the meal box. The potential of meal boxes to diminish different types of household food waste is investigated for the first time, across different countries. After providing a framework comparing the effects of different types of meals on food waste, we subsequently examine the effects of subscription-based food supply (i.e., meal boxes) on total meal waste as well as on the different types of food waste: preparation, cooking, and plate waste. Our dataset contains 8747 meal observations from 955 households in six countries. Results from a Bayesian multilevel hurdle-lognormal model with random intercept show that, overall, meal boxes reduce total meal waste in comparison to traditionally cooked dinners (38% reduction). Meal boxes especially lower the occurrence and amount of pan-and-pot food that is wasted (i.e., cooking waste), and also lower the amount of meal preparation waste, yet lead to a higher occurrence of both preparation and plate waste compared to traditional meals. This shows how differences between meals affect household food waste, something that has received little prior research attention. Furthermore, whereas most prior research has focused on overall household food waste, our study illustrates that distinguishing between different types of household food waste can provide important new insights.

    Description: Bis 1990 verlief durch den Schaalsee die deutsch-deutsche Grenze. 2021 treffen sich dort Menschen aus dem Osten und aus dem Westen, aus der Stadt und vom Land. Sie arbeiten heute schon für ein gutes Leben in und mit der Natur, und sie erzählen von einem anderen Morgen. MORGEN werden Lebensmittel wertvoll sein, wenn ihre Herstellung die Bodenfruchtbarkeit erhöht und das Wasser schützt. Davon können auch kleine Initiativen und Betriebe gut leben. Sie werden von einer Verwaltung unterstützt, die sich in der ökologischen Landwirtschaft gut auskennt. All das wird möglich, weil die Politik sich etwas traut. MORGEN wird der Wald vielfältig sein und kann sich selbst verjüngen. Denn er muss nicht mehr liefern, was Handwerk und Industrie brauchen, weil diese nun nehmen wollen, was der Wald kann. Die Politik hat verstanden, dass Wald in Verbindung mit Boden und Wasser ein elementares Gut ist. MORGEN werden die kleinen Energiewenden einfach zu verwirklichen sein. Neben klugen Kopplungen und Netzen gibt es regionale Eigenversorgung, und die mit der Herstellung von Strom und Wärme verbundene Wertschöpfung kommt den Gemeinden und Kommunen zugute. Die vielen kleinen Transformationen brauchen eine große Transformation - für eine friedliche, nachhaltige west-östliche Zukunft.

    Description: To address climate change, the decarbonisation of Germany's existing building stock urgently needs to be prioritised. However, the rate and depth of refurbishment has lagged behind official targets for years. This is a particular problem in the rental sector, where the costs and benefits of energy efficiency measures tend to be unevenly distributed between landlords and tenants (the so-called "landlord-tenant dilemma"). Within the context of the current policy landscape, investments in energy efficiency consequently make most sense for landlords if the upfront costs can be refinanced via increased rental income or reduced vacant periods. This paper seeks to investigate the validity of this statement at city level by using a large dataset from one of Germany’s main internet property platforms to examine how the willingness of tenants to pay for energy efficiency varies across residential locations in the city of Wuppertal. The small-scale spatial analysis highlights the existence of a price premium for energy efficiency in the rental market for apartments; however, this premium is generally small (especially in comparison to other property enhancements, especially visible improvements) or even non-existent in some residential areas. Consequently, investing in energy efficiency is rarely an attractive option for landlords. Therefore, strong policy action, aligned with social and urban development policy objectives, is necessary to establish an effective incentive structure in the market and make investing in energy efficiency more attractive for both landlords and tenants.

    Description: Deutschland liegt bei Klimaschutz und der langfristigen Sicherung der Energie- und Rohstoffversorgung weit hinter seinen eigenen Zielen. Nur mit Tempo, Mut und Ehrlichkeit lässt sich der Rückstand jetzt aufholen. Dazu gehören ein beschleunigter Ausbau erneuerbarer Energien, ein sofortiger Aufbau eines umfassenden Netzes für grünen Wasserstoff, verbindliche Ziele für eine echte Kreislaufwirtschaft, klare Vorgaben für den Wohnungsbestand, eine ernsthafte Mobilitätswende und wirksame Anreize für eine nachhaltige Produktion. Bei all dem müssen sozial gerechte Lösungen gefunden werden, nur so lässt sich CO2-Vermeidung und Ressourcenschutz in der Breite durchsetzen. Das vorliegende Impulspapier des Wuppertals Instituts zeigt, wie sehr Deutschland auf dem Weg zur Nachhaltigkeit seinen eigenen Zielen hinterherhinkt.

    Description: In the coming years, we must set a course that will allow as to protect our climate, reduce resource consumption, and preserve biodiversity. A profound ecological system change is on the horizon in all central areas of action of the economy and society, or transformation arenas. Digitalisation is a prerequisite for the success in this change and will impact these arenas at multiple levels: Digital technologies and applications will make it possible to improve current procedures, processes, and structures (Improve) and help us take the first steps towards new business models and frameworks (Convert). Despite this, digitalisation itself must be effective enough to facilitate a complete ecological restructuring of our society and lives to achieve more far-reaching economic transformation and value creation (Transform). The ability to obtain, link, and use data is a basic prerequisite for tapping into the potential of digitisation for sustainability transformation. However, data is not a homogeneous raw material. Data only gains value when we know the context in which it was collected and when we can use it for a specific purpose. The discussion on what structures and prerequisites are necessary for the system-changing use of data has only just begun. This study was conducted to serve as a starting point for this discussion as it describes the opportunities and prerequisites for a data-based sustainability transformation. This study focuses on environmental data, data from plants, machines, infrastructure, and IoT products. Our task will be to increase the use this data for systemic solutions (system innovation) within transformation arenas where different stakeholders are working together to initiate infrastructure, value chain, and business model transformation.

    Description: In den nächsten Jahren müssen die Weichen für Klimaschutz, zur Reduktion des Ressourcenverbrauchs sowie der Erhaltung der Artenvielfalt gestellt werden. In allen zentralen Handlungsbereichen von Wirtschaft und Gesellschaft - den sogenannten Transformationsarenen - steht ein tiefgreifender ökologischer Systemwandel an. Digitalisierung ist eine Erfolgsvoraussetzung für diesen Wandel und wirkt auf verschiedenen Ebenen: digitale Technologien und Anwendungen ermöglichen, gegenwärtige Verfahren, Prozesse und Strukturen zu verbessern (Improve) oder erste Schritte in eine neue Ausrichtung von Geschäftsmodellen oder Rahmenbedingungen zu gehen (Convert). Gleichzeitig muss die Digitalisierung aber auch für einen weitergehenden Umbau von Wirtschaft und Wertschöpfung sowie für die ökologische Neuorientierung von Gesellschaft und Lebensstilen wirksam werden (Transform). Die Fähigkeit zur Gewinnung, Verknüpfung und Nutzung von Daten ist eine Grundvoraussetzung, um die Potenziale der Digitalisierung für die Nachhaltigkeitstransformation zu erschließen. Daten sind dabei jedoch kein homogener Rohstoff - Daten erlangen erst einen Wert, wenn der Kontext, in welchem sie erhoben wurden, bekannt ist und sie für den angestrebten Zweck nutzbar gemacht werden können. Die Diskussion darüber, welche Strukturen und Voraussetzungen für die systemverändernde Nutzung von Daten erforderlich sind, hat erst begonnen. Die vorliegende Studie leistet hierzu einen ersten Beitrag und beschreibt die Möglichkeiten und Voraussetzungen für eine datenbasierte Nachhaltigkeitstransformation. Der Schwerpunkt liegt dabei auf Umweltdaten, Daten von Anlagen, Maschinen, Infrastrukturen oder von Produkten im Internet der Dinge (Internet of Things). Die Aufgabe ist, diese Daten stärker als bisher für systemische Lösungsansätze (Systeminnovationen) in den jeweiligen Transformationsarenen einzusetzen, bei denen unterschiedliche Stakeholder zusammenarbeiten und gemeinsam den Umbau von Infrastrukturen, Wertschöpfungsketten und Geschäftsmodellen einleiten.

    Description: The European Landscape Convention urges countries to involve stakeholders including citizens in the governance of ordinary (urban) landscapes. This paper studies conflicting stakeholder perspectives on urban landscape quality in the context of urban sustainability transitions in six European urban regions in the Netherlands, Italy, France, Croatia, Belarus and the Russian Federation. Repertory grid technique helped to identify the dimensions through which persons evaluate urban landscape quality. Ninety-three (93) interviewees elicited 1400 bipolar constructs, such as "Edible green - Concrete" or "Community, group - Loneliness". They then selected two constructs they consider most relevant in the context of urban sustainability transitions, and ranked all pictures on a 10-points scale. The rankings were analyzed using Multiple Correspondence Analysis. We find that, in spite of the many social and cultural differences between the regions, stakeholders largely agree on the preferred direction of urban transitions; more green and blue spots where people can meet and undertake joint (leisure) activities. The main conflict is between, on the one hand, a preference for organized development and beautification and, on the other hand, naturalness (permeability of soil) and organic development. The paper considers several challenges for transition governance.

    Description: In material development processes, the question if a new alloy is more sustainable than the existing one becomes increasingly significant. Existing studies on metals and alloys show that their composition can make a difference regarding the environmental impact. In this case study, a recently developed air hardening forging steel is used to produce a U-bolt as an example component in automotive engineering. The production process is analyzed regarding the environmental performance and compared with the standard quench and tempering steels 42CrMo4 and 33MnCrB5-2. The analysis is based on results from applying the method of Life Cycle Assessment. First, the production process and the alterations on material, product, and process level are defined. The resulting process flows were quantified and attributed with the environmental impacts covering Carbon Footprint, Cumulative Energy Demand, and Material Footprint as they represent best the resource-, energy- and thus carbon-intensive steel industry. The results show that the development of the air hardening forging steel leads to a higher environmental impact compared to the reference alloys when the material level is considered. Otherwise, the new steel allows changes in manufacturing process, which is why an additional assessment on process level was conducted. It is seen that the air hardening forging steel has environmental savings as it enables skipping a heat treatment process. Superior material characteristics enable the application of lightweight design principles, which further increases the potential environmental savings. The present work shows that the question of the environmental impact does not end with analyzing the raw material only. Rather, the entire manufacturing process of a product must be considered. The case study also shows methodological questions regarding the specification of steel for alloying elements, processes in the metalworking industry and the data availability and quality in Life Cycle Assessment.

    Description: Energiesparen ist durch den Krieg in der Ukra­ine das Gebot der Stunde, um uns unabhängig von russischen Energieträgern zu machen; vor Kriegsbeginn spielte dieses Thema keine allzu große Rolle in der breiteren politischen Diskus­sion. In Szenarien und Strategien, wie mittel­- und langfristige Klimaziele erreicht werden könnten, gewann das Thema Energiesparen durch Ener­giesuffizienz in den vergangenen Jahren hinge­gen immer mehr an Bedeutung, wobei die tech­nischen Strategien Effizienz und Konsistenz, also die Umstellung auf erneuerbare Energien, noch immer maßgebend sind. In diesem Beitrag zeigen wir, welche Rol­le das Senken des Energieverbrauches spielt, um Klimaziele zu erreichen, und warum dies eine ge­eignete Möglichkeit ist, multiple Krisen gleich­zeitig zu lösen. In Hinblick darauf ist Energie­suffizienz unabdingbarer Bestandteil möglicher Lösungsstrategien. Außerdem skizzieren wir, welche kurz­, mittel­- und langfristigen Politikin­strumente derzeit diskutiert werden, und ergän­zen dies um weitere Ideen zu Einsparpotenzialen sowie um Umsetzungsbeispiele.

    Description: A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy transition in MENA countries has been developed and applied to the case of Palestine. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision-makers. The transition towards renewable energies is still at a very early stage in Palestine. The long-standing political conflict between Palestine and Israel has prevented the large-scale deployment of renewable energy due to land restrictions. Palestine's political instability, its geographically fragmented territories, and its high dependence on Israel's imports are the most pressing concerns for Palestine’s electricity sector. At the operational level, particularly the transmission and distribution infrastructure need to be better interconnected, renewed and expanded to accommodate larger volumes of renewable electricity and at the same time improve efficiency. The modelled demand development shows that Palestine will most likely have to continue importing electricity even if the potential of renewable energy is fully exploited. This underlines the importance of sustainable energy partnerships for Palestine. The results of the analysis along the transition phase model towards 100% renewable energy are intended to stimulate and support the discussion on Palestine's future energy system by providing an overarching guiding vision for the energy transition and the development of appropriate policies.

    Description: The number of input-output assessments focused on energy has grown considerably in the last years. Many of these assessments combine data from multi-regional input-output (MRIO) databases with energy extensions that completely or partially depict the different stages through which energy products are supplied or used in the economy. The improper use of some energy extensions can lead to double accounting of some energy flows, but the frequency with which this happens and the potential impact on the results are unknown. Based on a literature review, we estimate that around a quarter of the MRIO-based energy assessments reviewed incurred into double accounting. Using the EXIOBASE MRIO database, we also analyse the effects of double accounting in the absolute values and rankings of different countries' and products' energy footprints. Building on the insights provided by our analysis, we offer a set of key recommendations to MRIO users to avoid the double accounting problem in the future. Likewise, we conclude that the harmonisation of the energy data across MRIO databases led by experts could simplify the choices of the data users until the provision of official energy extensions by statistical offices becomes a widespread practice.

    Description: Deutschlands Klimaschutzstrategie baut auf den Einsatz von grünem Wasserstoff aus erneuerbaren Energien. Doch wo soll der Wasserstoff herkommen, aus heimischer Produktion oder importiert aus dem Ausland? Eine Studie des Wuppertal Instituts und DIW Econ schafft einen Überblick über die aktuelle Datenlage und ermittelt Wertschöpfungs- und Beschäftigungseffekte beider Strategien. Das Resümee: Es trifft nicht zu, dass importierter Wasserstoff allgemein günstiger ist, entscheidend sind je nach Herkunftsland die tatsächlich realisierbaren Strom- und Transportkosten. Wird der grüne Wasserstoff stattdessen im eigenen Land produziert, wird dies zudem eine positive Beschäftigungswirkung und Wertschöpfung entfalten. Mit der Erreichung der Klimaziele 2050 betrüge die zusätzliche Wertschöpfung bei einer stark auf die heimische Erzeugung ausgerichtete Strategie bis zu 30 Milliarden Euro im Jahr 2050 und es könnten bis zu 800.000 Arbeitsplätze geschaffen werden.

    Description: By use of macro-economic model EXIOMOD, the expected impacts of actions described in the Strategic Research and Innovation Agenda (SRIA) have been analyzed. The results of this analysis show that the R&I actions described in the SRIA contribute to decoupling economic growth from resource use. The actions are expected to cause an increasing gross domestic product and a decreasing raw material demand. This results in an increasing extracted resource productivity, a measure used to show the decoupling of economic growth and resource use. It can however be questioned whether the actions in the SRIA - or the measures implemented in the model - assume a strong enough pace for decoupling economic growth and material use. The actions contribute to the climate goals of the European Commission, by showing a pathway through which the emissions of greenhouse gas can be reduced.

    Description: Wir stehen heute vor dem Klimaproblem. Das zu lösen ist seit mehr als 30 Jahren unsere Aufgabe. Dazu braucht es eine weltweite Energiewende. Politisch sind zwei global koordinierte Anläufe gemacht worden - und beide gescheitert. Gegenwärtig wird der dritte Versuch unternommen. Das zweimalige Scheitern ist nicht verwunderlich angesichts der Verfasstheit der globalen Politik. Gibt es eine Alternative? Die Antwort ist: ja, die technologische. Die vermag sich dank wirtschaftlicher Vorteilhaftigkeit von alleine durchzusetzen.

    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: For achieving a transition towards sustainable development, central importance is attached to science and education, and especially higher education. Suitable formats are needed for empowering students to perform transformative research. On the basis of transdisciplinary and transformative real-world laboratory research and futures studies, we develop encompassing learning and teaching module: the Transformative Innovation Lab (til). The lab builds on insights into five key competencies and three types of knowledge needed for developing socially robust sustainability innovations. In this paper, the main features of this experiential and reflexive format are presented and linked to a handbook for facilitating the lab. Central learnings for implementing the format in existing study programmes from two test runs at two German universities are shared and discussed.

    Description: Dem humorvoll skeptischen Blick auf den Zeitgeist zeigt sich ein seltsames Bild: Es scheint eine Zeit der Wenden ohne wirkliche Wende zu sein. So lange schon wird von "Wende" geschrieben und gesprochen, dass inzwischen beispielsweise in Verbindung mit Energie von alter (1980er-Jahre) und von neuer (2010er-Jahre) Energiewende die Rede ist. Viele Wenden sind in deutscher Sprachmanier zusammengesetzte Substantive und beziehen sich - von der Mobilitäts- über die Konsum- und die Agrar- bis hin zur Waldwende - auf ökologische Probleme. Manchen Wenden ist ein Adjektiv beigefügt, das eine Strömung im politisch-ökonomischen Raum beschreibt, so etwa die neoliberale Wende in der Sozialpolitik. Meist wird im Kontext der Ökologie konstatiert, dass die Probleme zwar bekannt, die eingeleiteten Wendestrategien und Wendemaßnahmen aber völlig unzureichend seien. Daher schlägt Benedikt Schmid eine "kritische Wende" vor. Die wachstums- und fortschrittsgebundenen Denkmuster gelte es aufzubrechen. Sie seien beharrlich und würden sich immer wieder auch in den zeitlichen und räumlichen Vorstellungen alternativer Ansätze einnisten. (1) Das Forschungsprojekt VorAB ("Vorsorgend handeln - Avantgardistische Brückenansätze für nachhaltige Regionalentwicklung") fragt nach strukturellen Hindernissen für nachhaltige Regionalentwicklung und nach Potenzialen fortschrittlicher Ansätze zu fairer Land- und Ressourcennutzung. (2) Es untersucht die Transformationsfelder Wald-, Energie- und Landwirtschaft in der Region Lübeck. Erste Ergebnisse zeigen, dass bei dem Terminus Wende mit Blick auf qualitative und grundlegende Veränderungen Vorsicht geboten ist.
