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: Over 175 million Nigerians rely on the use of traditional biomass for cooking, and it is estimated that more than 128,000 people died in Nigeria in 2019 from household air pollution related to these fuels. There is currently a gap in the study of possible pathways to meet Nigeria's goals in clean cooking and in understanding the health and climate impacts that different pathways can bring about. We explore clean cooking access scenarios for Nigeria until 2060 under a business-as-usual scenario, a moderate climate mitigation scenario, and an ambitious transformative scenario. We carry out a disaggregation at the state level for the period up to 2030 to better guide shorter-term policy development. Our analysis shows that under an ambitious scenario where 85 million households achieve access to clean cooking by 2060, annual premature deaths due to exposure to household air pollution would decrease by 7 % compared to 2018 levels. A baseline scenario, on the other hand, sees a dramatic 77 % increase, resulting in 209,000 people dying prematurely, of which 94,000 children under 5. Furthermore, we find that woodfuel removals from forestland would lead to a tripling of carbon dioxide emissions from land use change, reaching 602 Mt CO2 by 2060. Our findings stress the vital importance of a clean cooking transition in Nigeria and underline the urgent need for immediate acceleration in national efforts regarding access to clean cooking for all.

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: Education for Sustainable Development requires raising individuals' awareness of problems relevant to the environment. We designed a Generative Toolkit that supports industrial design students carrying out a Speculative Design task and through this process initiates greater problem awareness of low metal recycling rates. In this paper we give insights into the Toolkit's theoretical derivation and the design process. Findings from testing suggest that there are several opportunities for improvement, such as considering further content-related competencies in the Toolkit's design.

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: The steel industry is responsible for eight per cent of global CO2 emissions. As more than seven out of ten of today's coal-fired blast furnaces are due to be refurbished or replaced in the 2020s, there is a key window of opportunity to shift to low-emission production methods before the end of this decade. The analysis by Agora Industry, Wuppertal Institute and Lund University assesses eight potential breakthrough technologies in terms of their market readiness, cost and impact on emissions. The methods analysed include the use of hydrogen to produce direct reduced iron, scrap-based electric arc furnaces, electrolysis and the implementation of carbon capture in existing coal-fired facilities. While some of these technologies can already be deployed today to kick-start the market for green steel, others will take more time to reach technological maturity, but show promise in the long-term. A third group may never turn into adequate solutions for decarbonising the steel sector. In their analysis, the scientists conclude that scrap and hydrogen-based methods hold the biggest promise for companies aiming to make the switch this decade. By contrast, retrofitting existing coal-based facilities with carbon capture and storage (CCS) technology entails the biggest economic and environmental risk, the authors find. Regardless of the technologies chosen, appropriate regulatory frameworks, international cooperation, and targeted incentives are necessary to boost demand for green steel and promote its production. At the same time, such measures can help steer manufacturers away from costly technological dependencies.

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.
