Description: Germany is known for its ambitious climate policy targets. By 2045, the country seeks to achieve climate neutrality. As an intermediate step, the government has determined emission thresholds for different economic sectors through the year 2030. The industrial sector has so far not been a frontrunner in Germany's emission reduction efforts. Much of the country's success in this context is owed to the successful ramp-up of renewables in the electricity sector. For German industries, this means that they have little time left to undergo a substantial climate-friendly transformation by 2030. But how can this be achieved? This chapter introduces five different building blocks of Germany's climate strategy for its emission-intensive industrial sector: (1) The expansion of renewable energy for electricity production; (2) electrification and energy efficiency improvements; (3) the establishment of a green hydrogen economy; (4) the transformation towards a circular economy; and lastly (5) carbon capture and storage (CCS) and carbon capture and utilization (CCU). In an in-depth case study, the chapter reviews the particular role of CCU as a strategic component, discussing its potential as a climate strategy, its regulatory and legal framework, as well as insights on the broader societal acceptance of this technological approach.

Description: In order to avoid dangerous climate change and to satisfy the global energy needs energy systems have to change. Hopes are especially high in countries of the Global South for the low-carbon transition to propel sustainable development. Yet, while the energy transition provides opportunities, it also raises questions on how to avoid new global inequalities. This study presents the first quantitative approach to measure the extent to which the energy transitions in the Global South incorporate elements of energy justice. In doing so, this study builds on a rich literature on energy justice that differentiates between distributional, recognition, and procedural justice, thus taking into account social and development objectives such as affordability and accessibility of energy, the inclusion of marginalised parts of society, as well as broader community involvement and participation. Though much important conceptual and qualitative work has been done, what has been lacking so far is a quantitative measure of the degree to which the energy transition lives up to the imperative of energy justice, going beyond the much-studied Global North. The proposed energy justice index is designed and applied to select countries from Southeast Asia (Malaysia), sub-Saharan Africa (Kenya), the MENA region (Jordan), and Latin America (Chile). The index stands the test of the empirical application and demonstrates significant variation between countries along the different dimensions of energy justice. The study also emphasizes the importance of further testing and of improving data quality for informed policy making of energy justice issues in the Global South.

Description: Net zero targets have rapidly become the guiding principle of climate policy, implying the use of carbon dioxide removal (CDR) to compensate for residual emissions. At the same time, the extent of (future) residual emissions and their distribution between economic sectors and activities has so far received little attention from a social science perspective. This constitutes a research gap as the distribution of residual emissions and corresponding amounts of required CDR is likely to become highly contested in the political economy of low-carbon transformation. Here, we investigate what function CDR performs from the perspective of sectors considered to account for a large proportion of future residual emissions (cement, steel, chemicals, and aviation) as well as the oil and gas industry in the EU. We also explore whether they claim residual emissions to be compensated for outside of the sector, whether they quantify these claims and how they justify them. Relying on interpretative and qualitative analysis, we use decarbonization or net zero roadmaps published by the major sector-level European trade associations as well as their statements and public consultation submissions in reaction to policy initiatives by the EU to mobilize CDR. Our findings indicate that while CDR technologies perform an important abstract function for reaching net zero in the roadmaps, the extent of residual emissions and responsibilities for delivering corresponding levels of negative emissions remain largely unspecified. This risks eliding pending distributional conflicts over residual emissions which may intersect with conflicts over diverging technological transition pathways advocated by the associations.

Description: The Yangtze River Delta (YRD) region frequently experiences ozone pollution events during the summer and autumn seasons. High-concentration events are typically related to synoptic weather patterns, which impact the transport and photochemical production of ozone at multiple scales, ranging from the local to regional scale. To better understand the regional ozone pollution problem, studies on ozone source attribution are needed, especially regarding the contributions of sources at different vertical heights based on tagging the region or time periods. Between September 3 and 8, 2020, an episode of ozone concentration anomaly high was observed in Hefei through ground-based stations and ozone Lidar. The mechanism behind this event was uncovered through synoptic weather pattern analysis and using the Weather Research and Forecasting Chemistry model (WRF-Chem). Because an approaching typhoon caused variable wind direction, the O3-rich air masses (ORMs) arising from the YRD region were transported to Hefei via the nocturnal residual layer and descended to the ground through horizontal advection and vertical mixing processes the next day. Based on geographic source tagging, the anthropogenic NOx emissions (ANEs) from local and regional sources were the main contributors to the heavy ozone pollution over Hefei on September 6. Furthermore, the intra-regional transported ozone from southern Jiangsu (SJS), southern Anhui (SAH), and Zhejiang (ZJ) in the YRD was the main driving factor of the surface and upper atmosphere ozone pollution. Based on time period tagging, The ozone generated due to ANEs from September 3 to 5 significantly contributed to this episode. It is important to pay attention to the impact of ANEs on September 5 on the surface peak ozone concentration the following day (i.e., September 6). Our findings provide significant insights into the regional ozone transport mechanism in the YRD and optimization of measures to prevent and control heavy ozone pollution on spatiotemporal scales.

Description: Hydrological extremes, such as droughts and floods, can trigger a complex web of compound and cascading impacts (CCI) due to interdependencies between coupled natural and social systems. However, current decision-making processes typically only consider one impact and disaster event at a time, ignoring causal chains, feedback loops, and conditional dependencies between impacts. Analyses capturing these complex patterns across space and time are thus needed to inform effective adaptation planning. This perspective paper aims to bridge this critical gap by presenting methods for assessing the dynamics of the multi-sector CCI of hydrological extremes. We discuss existing challenges, good practices, and potential ways forward. Rather than pursuing a single methodological approach, we advocate for methodological pluralism. We see complementary or even convergent roles for analyses based on quantitative (e.g., data-mining, systems modeling) and qualitative methods (e.g., mental models, qualitative storylines). The data-driven and knowledge-driven methods provided here can serve as a useful starting point for understanding the dynamics of both high-frequency CCI and low-likelihood but high-impact CCI. With this perspective, we hope to foster research on CCI to improve the development of adaptation strategies for reducing the risk of hydrological extremes.

Description: Net-zero energy system configurations can be met in numerous ways, implying diverse economic effects. However, what is usually ignored in techno-economic and economy-wide analysis are the distinct social-political drivers and barriers, which might constrain certain elements of future energy systems. We thus apply a model ensemble that defines social-political storylines which constrain feasible net-zero configurations of the European energy system. Using these configurations in a macroeconomic general equilibrium model allows us to explore economy-wide effects and ultimately the cost-effectiveness of different systems. We find that social-political storylines provide valuable boundary conditions for feasible net-zero designs of the energy system and that the costliest energy sector configuration in fact leads to the highest European-wide welfare levels. This result originates in indirect effects, particularly positive employment effects, covered by the macroeconomic model. However, adverse public budget effects on the transition to net-zero energy may limit the willingness of policymakers who focus on shorter time-horizons to foster such a development. Our results highlight the relevance of considering the interaction of energy system-changes with labor, emission allowance and capital markets, as well as considering long-term perspectives.

Description: In academia and political debates, the notions of ‘degrowth’ has gained traction since the dawn of the 21st century. While some uncertainty around its exact definition remains, research on degrowth revolves around the idea of reducing resource and energy throughput as a unifying theme. We employ a mixed-methods design to systematically review the scientific peer-reviewed English literature from 2008 to 2022 that refers to ‘degrowth’ or ‘post-growth’ in title, keywords or abstract (N = 951). We find a lack of concrete distributional and monetary policy proposals in the sample analyzed, and a low overall degree of collaboration among authors in relation to degrowth's age and size. The scientific peer-reviewed literature analyzed can be grouped into seven clusters along two major gradients, one along methodology (qualitative-quantitative) and the other along scale-of-analysis (individual-societal). We conclude that the academic literature about degrowth would benefit from a more prominent discussion of the political implications of its ideas and proposals, and that in particular the debate about distributional policy implications of degrowth should be more prominent and concrete, with a stronger focus on distributional policies in a degrowing economy.

Description: Ausgehend von der Diskussion um Formalität und Informalität aus der Perspektive der Organisationssoziologie, der Regierungsforschung und der Politikberatung werden zunächst empirische Befunde aus einer Befragung von deutschen und polnischen Politikberatern, Lobbyisten und Experten zu ihren Wahrnehmungen der Zugangswege von Experten zur Politik und von der Politik zu Experten in Deutschland und Polen untersucht und ausgewertet. Welche Zugangswege werden gewählt und warum, wie offen sind sie, und welche Ungleichgewichte bestehen beim Zugang zu Experten und beim Zugang von Experten zur Politik? Ein zweiter Abschnitt befasst sich mit dem Grad der Formalisierung von deliberativen Prozessen und Zugangskanälen in beiden Ländern. In einem dritten Abschnitt liegt der Schwerpunkt auf der Interpretation der Wahrnehmung der Zugangskanäle und des Formalisierungsgrades und deren Implikationen für die Politikberatung in Deutschland und Polen.

Description: Klassische Ansätze der Politikberatung unterscheiden zwischen Anbietern (i.d.R. Experten) und Empfängern (i.d.R. Politiker) von Politikberatung. Das Konzept einer politikorientierten Gesellschaftsberatung erweitert dieses Verständnis um eine zusätzliche, eigenständige Rolle für die Bürgerinnen und Bürger. Unter Verwendung der Heuristik von Römmele & Schober (2011) betrachten wir Bürgerratsprozesse aus Deutschland und Polen, innerhalb derer zufällig geloste Bürgerinnen und Bürger dazu beitragen können, Lösungen für komplexe und konfliktäre gesellschaftspolitische Herausforderungen zu entwickeln. Deliberative Mini-Publics, wie diese Bürgerräte, ermöglichen die Einbeziehung der Bürgerinnen und Bürger als beratende Stimme in Gesellschaftsberatungs-Prozessen. In diesem Kapitel erörtern wir die Merkmale solcher Formate und beleuchten ihre Funktionen und Rahmenbedingungen, die erfüllt sein sollten, damit ihr Einsatz zielführend und wirksam ist. Außerdem vergleichen wir Bürgerräte in Polen und Deutschland mit Blick auf das Beratungsmandat dieser Gremien.

Description: As climate targets tighten, all countries must transition toward a renewable electricity system, but conflicts about generation and infrastructure deployment impede transition progress. Although the triggers of opposition are well studied, what people want remains understudied. We survey citizen preferences for a renewable electricity future through a conjoint analysis among 4,103 individuals in Denmark, Portugal, Poland, and Germany. With our study we go beyond the Likert scale survey approach specifically seeking trade-offs and contextualized preferences for regional electricity system designs. We show the importance of identifying both the ‘‘least preferred’’ and ‘‘most preferred’’ solutions and highlighting the possibility of identifying very different systems with identical utility. Lastly, our research actively bridges the divide between social aspects and techno-economic modeling, promoting their integration. We show that the most preferred system design in all four countries is a predominantly regional one, based on rooftop solar, communally owned, and not relying on transmission expansion.

Description: Background This article asks the following question: how well are coal regions, affected by phase-out plans, represented in mediating commissions, to what extent do local communities participate in the decision-making process and how are the political negotiations perceived by the communities? We look at the case of the German lignite phase-out from a procedural justice perspective. Informed by literature on sociotechnical decline and procedural justice in energy transitions, we focus first on aspects of representation, participation and recognition within the German Commission on Growth, Structural Change and Employment (“Coal Commission”). Second, we analyze how to exnovate coal in two regions closely tied to the coal- and lignite-based energy history in Germany: Lusatia and the Rhenish Mining District. Results Based on interview series in both regions, we connect insights from local communities with strategies for structural change and participation programs in the regions. We find significant differences between the two regions, which is primarily an effect of the challenging historical experiences in Lusatia. Participation within existing arrangements is not sufficient to solve these problems; they require a comprehensive strategy for the future of the regions. Conclusions We conclude that the first phase-out process was a lost opportunity to initiate a community-inclusive sustainable transition process. As the phase-out process is not yet concluded, additional efforts and new strategies are needed to resolve the wicked problem of lignite phase-out.

Description: Bürgerräte basieren auf einer einfachen Idee: Per Los ausgewählte Menschen aus allen Teilen der Gesellschaft sollen stärker an politischen Entscheidungen beteiligt werden. Da das Instrument aber viel Gestaltungsfreiheit zulässt und je nach Thema und lokalen Gegebenheiten unterschiedlich umgesetzt werden kann, stellen sich bei der Ausgestaltung eines konkreten Verfahrens viele Fragen. Fast täglich erreichen uns Beratungsanfragen zu geplanten Bürgerräten durch Initiativen oder Mitarbeiterinnen und Mitarbeiter der Verwaltung. Diesen Bedarf greifen wir mit dem vorliegenden Handbuch auf. Es soll zivilgesellschaftliche und staatliche Akteurinnen und Akteure dabei unterstützen, Bürgerräte in der Praxis an für die jeweilige Kommune spezifischen Zielen und Bedingungen auszurichten. Aus der Erfahrung mit Bürgerräten in Deutschland und der Welt lassen sich entscheidende Faktoren für das Gelingen des Formats ableiten: Es hat sich gezeigt welche Praxis sich bewährt hat — und welche nicht. Das Handbuch bündelt dieses Wissen. Es bietet Orientierung für alle Phasen, die ein Bürgerrat durchläuft: von der ersten Idee bis zur Verwendung der Ergebnisse durch die Politik. Die Bürgerrat-Sitzungen betrachten wir in den folgenden Kapiteln also genauso wie die Initiierung des Verfahrens, dessen Vorbereitung und die Prozesse im Nachgang. Dabei formulieren wir Leitfragen für die Vorbereitung und Durchführung und weisen auf entscheidende Momente hin, in denen Richtungsentscheidungen getroffen werden müssen. Für alle Prozessschritte geben wir Anregungen zu möglichen Varianten, konkrete Tipps zur Umsetzung und Beispiele aus dem internationalen Kontext. Das Handbuch nimmt den Organisatorinnen und Organisatoren die Arbeit — und den Spaß — der Vorbereitung eines Bürgerrats nicht ab. Aber es ist eine unerlässliche Hilfe, um im Blick zu behalten, welche Entscheidung das Verfahren in welche Richtung führt. Wir hoffen, dass wir auf diese Weise viele Menschen in Initiativen und Verwaltungen, in der Politik und in Prozessgestaltungsunternehmen bei der Organisation von kommunalen Bürgerräten unterstützen können.

Description: L’alimentation est à la fois un levier central pour engager la transition socio-écologique et un theme quotidien tangible pour chaque citoyen.ne. En Allemagne comme en France, quelques collectivités territoriales engagent des mesures innovantes pour promouvoir une alimentation locale et durable. Le Forum pour l’avenir franco-allemand s’est penché sur les expériences de certaines de ces collectivités et a facilité le dialogue entre elles durant plusieurs mois afin de comprendre quelles politiques nationales peuvent soutenir de telles initiatives locales. En associant des expert.e.s issus de la sphère scientifique, de l’administration et de la société civile, il a recommandé de « Donner la priorité au développement de systèmes alimentaires locaux et durables » avec cinq propositions d’action concrètes aux gouvernements français et allemand. Cette étude présente les initiatives françaises et allemandes ayant nourri les propositions d’action du Forum pour l’avenir.

Description: Food and food policy is central to social-ecological transformation. It is also an everyday issue that is easy to communicate to citizens. Municipalities in Germany and France have recognized the potential of innovative local food policies and have developed and tested innovative approaches to transforming local food systems. However, they are encountering structural barriers that cannot be overcome at the municipal level. The Franco-German Forum for the Future has researched the opportunities and obstacles of local nutritional change and brought engaged municipalities from both countries into exchange with each other. Together with experts from academia, public administrations and civil society, it has developed the seven recommendations for the national governments, one of which concerns "Prioritizing the development of local and sustainable food systems" with five proposals for action. This study is intended as a background paper to the Recommendation. With recourse to the concrete example of Mouans-Sartoux and other municipalities in France and Germany, it describes the potentials of a sustainable municipal food policy and provides – from concrete local practice – the background knowledge for each of the five proposals for action.

Description: Transdisciplinary problems are complex, ill-defined, societal real-world problems with high ambiguity that are contested and require multiple trade-offs. Part I of this paper showed that transdisciplinary processes include seven types of knowledge integration: system (ontological), epistemological, cultural, cognitive, social conflict, evolutionary (levels of representation), and complexity-theory-based types of knowledge integration. The epistemological integration of the different modes of reasoning from science and practice is a unique selling point of the transdisciplinary process. Part II presents five transdisciplinary processes for the responsible use of digital data in different vulnerable/sensitive subsystems of Germany (mobility, health, agriculture, SME, and social media). Between 10 and 18 participants (equally representing science and practice in each group) synchronously constructed socially robust orientations as pillars of a white book. We elaborate that outcomes of a transdisciplinary process can be improved, and barriers diminished by reflecting on which of the seven types of knowledge integration are applied (see Part I). This is done for the six phases of a transdisciplinary process: (1) triggering, (2) initiation, (3) preparation, (4) planning, (5) core, and (6) post-processing. We particularly address researchers and practitioners who seek insights into how the production and integration of knowledge can be improved by transdisciplinary processes.

Description: Non-traditional and transnational actors have become essential for environmental and climate change governance. One of these actors, the Climate and Clean Air Coalition (CCAC), has taken over a lead role in the governance of SLCPs. Since 2012, the CCAC has been pushing for an increased political dialogue on the one hand, and fostering technical expertise, projects, and a knowledge network on the other hand. This voluntary alliance is an interesting research subject because it brings together a mix of over 150 governmental, intergovernmental, NGO, and scientific members, who closely work on reducing global near term-warming as well as improving air quality, health, and further aspects of sustainable development. This chapter focuses on the CCAC’s role in the international policy landscape and on what it can contribute to SLCP governance. It describes the CCAC’s structure, modus of operation, and activities, and then scrutinizes its potential and challenges for SLCP governance. Furthermore, this text seeks to provide a perspective on the CCAC in the global climate and environmental policy landscape.

Description: Crises may act as tipping points for decarbonization pathways by triggering structural economic change or offering windows of opportunity for policy change. We investigate both types of effects of the global financial and COVID-19 crises on decarbonization in Spain and Germany through a quantitative Kaya-decomposition analysis of CO2 emissions and through a qualitative review of climate and energy policy changes. We show that the global financial crisis resulted in a critical juncture for Spanish CO2 emissions due to the combined effects of the deep economic recession and crisis-induced structural change, resulting in reductions in carbon and energy intensities and shifts in the economic structure. However, the crisis also resulted in a rollback of renewable energy policy, halting progress in the transition to green electricity. The impacts were less pronounced in Germany, where pre-existing decarbonization and policy trends continued after the crisis. Recovery packages had modest effects, primarily due to their temporary nature and the limited share of climate-related spending. The direct short-term impacts of the COVID-19 crisis on CO2 emissions were more substantial in Spain than in Germany. The policy responses in both countries sought to align short-term economic recovery with the long-term climate change goals of decarbonization, but it is too soon to observe their lasting effects. Our findings show that crises can affect structural change and support decarbonization but suggest that such effects depend on pre-existing trends, the severity of the crisis and political manoeuvring during the crisis.

Description: Simulating the ozone variability at regional scales using chemistry transport models (CTMs) remains a challenge. We designed a multi-model intercomparison to evaluate, for the first time, four regional CTMs on a national scale for Germany. Simulations were conducted with LOTOS-EUROS, REM-CALGRID, COSMO-MUSCAT and WRF-Chem for January 1st to December 31st, 2019, using prescribed emission information. In general, all models show good performance in the operational evaluation with average temporal correlations of MDA8 O3 in the range of 0.77-0.87 and RMSE values between 16.3 mu g m3 and 20.6 mu g m- 3. On average, better models' skill has been observed for rural background stations than for the urban background stations as well as for springtime compared to summertime. Our study confirms that the ensemble mean provides a better model-measurement agreement than individual models. All models capture the larger local photochemical production in summer compared to springtime and observed differences between the urban and the rural background. We introduce a new indicator to evaluate the dynamic response of ozone to temperature. During summertime a large ensemble spread in the ozone sensitivities to temperature is found with (on average) an underestimation of the ozone sensitivity to temperature, which can be linked to a systematic underestimation of mid-level ozone concentrations. During springtime we observed an ozone episode that is not covered by the models which is likely due to deficiencies in the representation of background ozone in the models. We recommend to focus on a diagnostic evaluation aimed at the model descriptions for biogenic emissions and dry deposition as a follow up and to repeat the operational and dynamic analysis for longer timeframes.

Description: Today, populism is widely understood to entail an exclusionary conception of “the people” that threatens climate change action. While this threat is real, I argue that populism itself can be understood as a response to perceived exclusion and marginalization, making it possible to conceptualize a more heterogeneous conception of populism’s “people.” Examining two approaches to climate change action rooted in contrasting conceptions of the people and the elite, I argue that climate justice organizing offers a promising effort to construct a heterogeneous people and offers a powerful critique of the elite representation of climate change action in which “we are all in this together.” Yet along with this promise, climate justice organizing must navigate tensions that are inescapable within any populist formation. One neglected thread of populist history and theory offers resources for doing so; in the final section of this paper, I explore its relevance to climate justice today.

Description: The Corona pandemic was one of the most challenging political events of the last decades in Europe in which many important political issues had to be decided within a very short space of time. Deliberative, sortition-based formats offer new approaches to strengthen democracy in times of crisis but have so far mainly been used for fundamental issues that have been under discussion for a long time. In Germany, four Corona Citizens’ Councils were organized at different levels to deal with the highly dynamic pandemic situation. The first was on local level and took place in the city of Augsburg, the next and most prominent one in the state of Baden-Wurttemberg (‘Bürgerforum Corona’), being held monthly over a period of 13 months. Another one was organized in the state of Saxony, a fourth one in Thuringia. The article examines the background, the methodological quality and the outcomes of three Corona Citizens’ Councils in Germany. The article compares the three Citizens’ Councils and draws conclusions about the crisis-management capacities of deliberative formats in dealing with pressing political issues in highly dynamic situations.

Description: Nachhaltigkeit ist als normative Grundlage politischer Entscheidungen zur Transformation des Energiesystems nicht mehr wegzudenken. Sämtliche wirtschaftlichen Prozesse beruhen auf der Extraktion (vor allem) nicht-erneuerbarer Ressourcen, deren energetischer Umwandlung und Nutzung in Produktionsprozessen (von Gütern bzw. für die Bereitstellung von Dienstleistungen) sowie der daraus resultierenden negativen Externalitäten als ökologische Kosten, z. B. die Belastung ökologischer Senken (Atmosphäre, Wälder, Meere, etc.).

Description: Wenn das noch was werden soll mit der Mobilitätswende, müssen wir Gas geben. Als Leserin oder Leser der mobilogisch! wissen Sie schon: Die Mobilitätswende ist eine große und komplexe Baustel- le, da geraten wir schnell ins Schleudern.

Description: Introduction Current urban and transport planning practices have significant negative health, environmental, social and economic impacts in most cities. New urban development models and policies are needed to reduce these negative impacts. The Superblock model is one such innovative urban model that can significantly reduce these negative impacts through reshaping public spaces into more diverse uses such as increase in green space, infrastructure supporting social contacts and physical activity, and through prioritization of active mobility and public transport, thereby reducing air pollution, noise and urban heat island effects. This paper reviews key aspects of the Superblock model, its implementation and initial evaluations in Barcelona and the potential international uptake of the model in Europe and globally, focusing on environmental, climate, lifestyle, liveability and health aspects. Methods We used a narrative meta-review approach and PubMed and Google scholar databases were searched using specific terms. Results The implementation of the Super block model in Barcelona is slow, but with initial improvement in, for example, environmental, lifestyle, liveability and health indicators, although not so consistently. When applied on a large scale, the implementation of the Superblock model is not only likely to result in better environmental conditions, health and wellbeing, but can also contribute to the fight against the climate crisis. There is a need for further expansion of the program and further evaluation of its impacts and answers to related concerns, such as environmental equity and gentrification, traffic and related environmental exposure displacement. The implementation of the Superblock model gained a growing international reputation and variations of it are being planned or implemented in cities worldwide. Initial modelling exercises showed that it could be implemented in large parts of many cities. Conclusion The Superblock model is an innovative urban model that addresses environmental, climate, liveability and health concerns in cities. Adapted versions of the Barcelona Superblock model are being implemented in cities around Europe and further implementation, monitoring and evaluation are encouraged. The Superblock model can be considered an important public health intervention that will reduce mortality and morbidity and generate cost savings for health and other sectors.

Description: The topic of greenhouse gas emissions embodied in products is gaining in prominence and the possibilities for measuring and verifying them are improving. This provides fertile ground for those who demand that climate policy should address such embodied emissions. There are different design options for policies targeting embodied emissions. Such differences affect which groups can be mobilized in their favour. This paper shows that procurement standards which target intermediate products can mobilize the support of relatively low carbon producers of high carbon materials, while product standards which target final products can mobilize the support of producers of relatively low carbon materials and knowledge-intensive service providers.

Description: Real-world labs make the mobility transition tangible for residents. However, these experiences are not always positive, and often local conflicts arise. Based on in-depth interviews, the authors show that perceived procedural unfairness as well as the redistribution of space are the main drivers of a sceptical attitude towards redesign projects. Real-world labs (RwLs) are often used to explore and foster the mobility transition. Many RwLs dealing with mobility transition temporarily reallocate public spaces from motorized to active transport or to leisure activities. While some residents accept and enjoy the changes, others react with scepticism, rejection, or protest. This can lead to conflicts. Controversial perceptions and conflicts among residents make a permanent redesign rather challenging for the administration and the politicians. In this paper the authors investigate the related conflict types and counterarguments by studying the case of a temporary redesign of an intersection in Berlin. Based on in-depth interviews, they untangle procedural, distributional, and identity conflicts which might underlie the critical and ambivalent perceptions of residents. An abundance of conflict issues pertaining to procedural and distributional conflicts are revealed and emphasize the role of the RwL process.

Description: Transdisciplinary processes deal with transdisciplinary problems that are (i) complex, (ii) societally relevant, (iii) ill-defined, and (iv) real-world problems which often show a high degree of ambiguity resulting in contested perceptions and evaluations among and between scientists and practitioners. Therefore, they are susceptible to multiple trade-offs. Transdisciplinary processes construct socially robust orientations (SoROs) particularly for sustainable transitioning. The integration of science and practice knowledge on equal footing (1) is considered the core of transdisciplinary processes. Yet other forms of knowledge integration contribute essentially to construct SoROs. Individuals may (2) use different modes of thought; (3) refer to various cultures with diverse value and belief systems; and (4) problems are perceived and prioritized based on roles and interests. Coping with transdisciplinary problems, (5) purposeful differentiation and integration and (6) an integration of evolutionary evolving codes of representing knowledge are necessary. Finally, (7) what systems to integrate requires consensus-building among participating scientists and practitioners. This paper is Part I of a two-part publication. It provides a conceptualization of the different types of knowledge integration. Part II analyzes tasks, challenges, and barriers related to different types of knowledge integration in five transdisciplinary processes which developed SoROs for sensitive subsystems of Germany affected by the irresponsible use of digital data.

Description: Klimapolitik ist aufgrund ihrer Komplexität und Reichweite mehr denn je auf innovative Beteiligungsverfahren angewiesen. Mit Hilfe innovativer Formate wie dem analytisch-deliberativen Diskurs, erhalten betroffene Bürger:innen die Gelegenheit, in einem Klima gegenseitiger Anerkennung, sowie des Respekts vor der Legitimität unterschiedlicher Wertesysteme und Präferenzen Probleme neu zu definieren, alternative Handlungsoptionen zu diskutieren und die damit verbundenen Folgen und Implikationen zu bewerten. Solche verständigungsorientierte Diskurse können gerade in der Klimapolitik helfen, komplexe Sachverhalten zu klären, Ziele und Strategien zu reflektieren und gemeinsam eine sach- und wertgerechte Gestaltung der Klimapolitik vorzubereiten.

Description: The Paris Agreement requires countries to break away from carbon lock-in, a particular challenge for traditional oil and gas producers. How can these countries overcome path-dependencies to shift from a fossil fuel heavy system to one relying on renewable energy? Malaysia epitomizes this challenge: the country is the second-largest oil producer in Southeast Asia whilst the fossil fuel energy sector takes up nearly 80 % of total greenhouse gas (GHG) emissions, with coal energy occupying the largest share. To identify leverage points of energy transitions, we model the structural components influencing the Malaysian energy system and assess the dynamics of interrelating factors. Based on stakeholders' input, we identify main factors influencing Malaysia's energy transition, explore their interactions, and use Cross Impact Balances (CIB) to create scenarios. Our analysis reveals the need to simultaneously disperse the centralized political power to a more diverse set of actors whilst introducing green growth recovery packages to break the carbon lock-in. Whilst focused on Malaysia, the findings contribute more generally to our understanding how fossil fuel reliant emerging economies can break path-dependencies inhibiting the clean energy transition.

Description: The transport sector and especially private cars pose environmental, economic, and social challenges. For this reason, cargo bikes and shared mobility are considered viable alternatives for road transport. In order to understand the potential and barriers of alternative transport modes, it is essential to analyze underlying motives. Moreover, comparing sustainable alternatives (such as public transport) to cars in terms of motives has been established as a research approach (Steg, 2003). Despite increasing interest in cargo bikes and cargo bike sharing, research on this topic is relatively rare. Particularly, there exists a lack of research addressing the impact of cargo bike sharing on car ownership. Against this background, this study quantifies the car ownership reduction effect of cargo bike sharing. In addition, it is investigated how cargo bikes differ from cars with regard to the underlying motives of users which also helps understanding potential barriers. To answer these research questions, this study is based on a large-scale survey with n = 2,590 cargo bike sharing users. The results imply that cargo bike sharing has a notable impact on car ownership. In general, cargo bikes are rated superior in regard to affective, symbolic, and environmental motives as well as on flexibility and price. However, discrepancies to cars do exist in terms of other instrumental aspects (traffic safety, travel speed, comfort, weather-independence). Notably, users who reduced car ownership tend to rate cargo bikes superior compared to car-dependent users. The results imply that cargo bikes can play a marked role in reducing car dependency. Improving infrastructure and cargo bike technology as well as stimulating favorable social norms for cargo bikes have been identified as beneficial conditions that could help to leverage this potential.

Description: We study the impact of California’s cap-and-trade system on carbon emissions in the electricity and industrial sectors. We use US state-level panel data covering the period 2005–2019 and apply the synthetic control method to construct an optimal counterfactual for per capita emissions in each sector. In our experiment, emissions in the power sector fall below counterfactual emissions by 48%. In the industrial sector, the state’s emissions are 6% higher than those of the synthetic control unit by the end of the observation period. Thus, cap-and-trade failed to deliver decarbonization across both sectors. While the abatement in the power sector was facilitated by complementary policies and driven by a switch from natural gas to renewables, California’s policy mix has disincentivized emission reductions in the industrial sector.

Description: In sustainability transitions research, the deliberate destabilisation of socio-technical regimes is increasingly recognised as a central intervention point. Absent, however, are granular approaches for assessing whether regime destabilisation actually occurs in processes of systemic change. We propose to assess regime destabilisation through shifts in the institutionalisation of field logics. Methodologically, we employ Socio-Technical Configuration Analysis to map changes over time in the composition and alignment of institutional and technological concepts embedded in sectoral policy. Empirically, we assess the extent to which post-Brexit agricultural policy reform in the United Kingdom marks the destabilisation of an unsustainable regime. Assessing legislative debate transcripts, we find that the previously dominant regime is only partly destabilised, as pre-existing development trajectories along established configurations of field logics, policy goals and instruments remain. These findings support the validity of our conceptual approach. Moreover, they nuance expectations about large-scale policy change as windows of opportunity for regime shifts.

Description: The question of how science can become a lever in achieving the Sustainable Development Goals permeates most recent sustainability research. Wide-ranging literature calling for a transformative approach has emerged in recent years. This ‘transformative turn’ is fueled by publications from fields such as sustainability science, social-ecological research, conservation science, sustainability transitions, or sustainability governance studies. However, there is a lack of a shared understanding specifically of what is meant for research to be transformative in this developing discourse around doing science differently to tackle sustainability problems. We aim to advance transformative research for sustainability. We define transformative research and outline six of its characteristics: (1) interventional nature and a theory of change focus; (2) collaborative modes of knowledge production, experimentation and learning; (3) systems thinking literacy and contextualization; (4) reflexivity, normative and inner dimensions; (5) local agency, decolonization, and reshaping power; (6) new quality criteria and rethinking impact. We highlight three tensions between transformative research and traditional paradigms of academic research: (1) process- and output-orientation; (2) accountability toward society and toward science; (3) methodologies rooted in scientific traditions and post-normal methodologies. We conclude with future directions on how academia could reconcile these tensions to support and promote transformative research.

Description: Dominant ways of doing research are not enough to achieve the UN Sustainable Development Goals. The typical response of science to dealing with the current local and global sustainability crises is to produce and accumulate more knowledge. Transformative research seeks to couple knowledge production with co-creating change. This paper defines the transformative way of doing research to pro-actively support society's fight against pressing societal and environmental problems. We present six characteristics of transformative research. We reflect on the challenges related to implementing these characteristics in scientific practice and on how academia can play its part.

Description: Zentrale Aushandlungs- und Gestaltungsprozesse in der Energiewende finden vor Ort in den Regionen und Kommunen statt. Wie gelingt es hier, die Transformation demokratisch zu gestalten und das politische Versprechen von Teilhabe und Mitgestaltung einzulösen? Dieser Frage widmet sich die vorliegende Studie. Um herauszufinden, welche Erfolgsfaktoren und Herausforderungen in Ansätzen der finanziellen Beteiligung sowie in dialogischen und konfliktsensiblen Formaten liegen, haben wir drei unterschiedliche Fallbeispiele zu materieller und immaterieller Beteiligung in der Energiewende analysiert. Auf dieser Grundlage benennt die Studie fünf konkrete Handlungsempfehlungen zur Stärkung von kommunalen Transformationskapazitäten für Bund und Länder.

Description: Strategies for mitigating climate change today include plans for removing carbon dioxide from the atmosphere through “Negative Emissions Technologies” (NETs). NETs create new opportunities for scientific research, technology development, and the development of financial products, but also new conceptual possibilities, for example of declaring one’s ambition to become “climate neutral.” NETs thus constitute a novel frontier in climate science and politics whose conditions of possibility, characteristics, and consequences can be studied by social scientists and humanists. For environmental sociologists, NETs pose numerous opportunities for engaging with questions around future-making, imaginaries, promises, expertise, markets, infrastructure, justice, publics, and generally, the shape and role of science and technology in a form of social life that is increasingly organized around “planetary” concepts.

Description: CrossGov D2.1 EU and international policy landscape - Mapping EU policies and Green Deal objectives: general observations for policy coherence in the marine domain aims to provide a mapping of the European Green Deal policy landscape relevant to the marine domain and the CrossGov project. It also offers a general introduction into how policy coherence, embedded within the design of (selected) EU policies, supports or impedes progress towards the EGD’s objectives in the marine domain. A total of 36 policies were selected and mapped against five EGD strategies, namely the 2030 Climate Target Plan, the EU Climate Change Adaptation Strategy, the Biodiversity Strategy for 2030, the Zero Pollution Action Plan, and the Sustainable Blue Economy Strategy. These five strategies lay out a total of 25 specific objectives to implement the vision of the EGD, identified as relevant to the marine domain and the focus of the CrossGov project – i.e. climate change, biodiversity loss, and pollution.

Description: Technologien für CO₂-Abscheidung und -Speicherung machen Hoffnung, werden aber gleichzeitig als Rechtfertigung für die geringe Reduktion von Emissionen aus fossilen Energiequellen genutzt. Das ist nicht vereinbar mit dem Ziel, die Erderwärmung auf 1,5 oder 2 °C zu begrenzen.

Description: This paper discusses the key questions and challenges for promoting international cooperation between the EU and potential international partners within an emerging hydrogen economy. On this basis, it identifies entry-points for related policy action. Specifically, it outlines six policy dimensions that European policymakers should consider when engaging in the development of international partnerships within the emerging hydrogen economy: climate mitigation, green industrial development in Europe, just transitions in partner countries, geopolitics, security of supply, and economic feasibility. Taking these six dimensions as its starting point, the paper presents nine policy messages for the development of an international hydrogen economy within the context of broader decarbonisation efforts in the EU.

Description: The impacts of deep seabed mining on people have not been sufficiently researched or addressed. Using a legitimacy framework, we discuss the social-equity dimensions of this emerging industry in the ocean commons.

Description: In mid-2021, the Republic of Nauru invoked a treaty provision at the International Seabed Authority known as the “two-year rule”. This effectively imposed a deadline on the Council of the International Seabed Authority to complete the elaboration and adoption of regulations for the exploitation of seabed minerals in the international seabed Area by 9 July 2023. Come 10 July 2023, the Authority would be presented with a new legal situation, whereby applications for mining activities may be submitted despite the absence of applicable regulations. There remain many outstanding matters in the negotiations and, considering that the regulations for exploitation must be adopted by consensus at the Council, it would appear that there is still a long and winding road ahead before an agreement is reached among member states – if this is at all possible. In light of this, the Council clearly needs to discuss what would occur if an application for the approval of a plan of work for exploitation activities happens to be submitted in the absence of applicable regulations. While the open legal questions that arise from the invocation of the two-year rule and upon the expiration of the deadline have been analysed elsewhere, this discussion paper examines the new political reality that the Authority finds itself in following the expiry of the deadline on 9 July 2023. Building on previous work by the author, this discussion paper attempts to underscore what is at stake at the Authority and explores how member states should approach this situation.

Description: The marine environment is under increasing threat from the cumulative effects of human activities. This chapter examines and elaborates on some of the important challenges facing international marine environmental law today. To situate the discussion, the chapter begins with an overview of the background to and development of international marine environmental law and the principles and processes that form the corpus of this body of law. It then turns to an examination of legal frameworks relating to some of the most pressing current challenges, including biodiversity loss, plastic pollution, climate change and the role of science and technology. The chapter concludes that international marine environmental law alone cannot protect the marine environment. Rather, cooperation between sectors and with other legal regimes such as the climate, biodiversity and waste regimes is now essential.

Description: This paper examines the challenges and prospects for Norway’s internal and external hydrogen strategy from around 2019, when Norway’s low-carbon hydrogen policies and activities began to gain traction. Norway has taken a technology-neutral approach to ‘green’ and ‘blue’ hydrogen technologies linked to reducing emissions. Two end-use sectors have been prioritised: maritime transport and energy-intensive industries. This strategy is based on Norway’s energy mix, industry structure/interest and research competence. While climate concerns appear as the predominant motivation underlying the Norwegian government’s low-carbon hydrogen strategy, industrial value creation is an additional key goal. Political priorities roughly align with actual funding priorities – there has been a massive increase in direct state aid to low-carbon hydrogen projects. Externally, Norway’s hydrogen strategy has potential significance for Europe, particularly for countries with maritime interests and high hydrogen import needs. However, Norway’s technology-neutral approach deviates from most other European countries. What Norway’s hydrogen strategy will mean for Europe remains to be seen – but its main interests concern the export of ‘blue’ hydrogen, with ‘green’ hydrogen primarily suited to meet domestic needs.

Description: The COVID-19 pandemic has led to a surge in online communication, offering a unique burning glass perspective on the advantages of transferring formerly face-to-face conversations online as well as uncovering limitations of using technical applications to this end. These experiences are of great importance for the development of new e-participation instruments. So far, digital participation has failed to match the quality of real-world procedures. This paper discusses various emerging formats for online participation and their prerequisites. Blended participation models, in particular, appear to offer the most promise, enhancing negotiation processes between heterogenous social groups and facilitating responsive policy making.

Description: Die Corona-Pandemie hat die Nutzung der Online-Kommunikation stark befördert. Diese einzigartige experimentelle Situation machte die Möglichkeiten und Grenzen eines Wechsels der Kommunikationsmedien von Face-to-Face- in Online-Formate sichtbar. Die gesammelten Erfahrungen sind von erheblicher Bedeutung für die Entwicklung neuer Instrumente und Tools der Online-Beteiligung. Bislang allerdings sind Online-Beteiligungsformate den klassischen Offline-Beteiligungsformaten qualitativ nicht ebenbürtig. Daher werden in diesem Beitrag Ansatzpunkte für neue Formate und deren Grundvoraussetzungen diskutiert. Insbesondere Konzepte, welche sowohl Online- als auch Offline-Elemente verbinden (Blended Participation), erscheinen vielversprechend, da sie Austauschprozesse zwischen heterogenen sozialen Gruppen verbessern und die Responsivität des politischen Entscheidungsfindungsprozesses erhöhen können.

Description: Little consideration has been given to the process of technological change in political theory. Given that ideas about this process play an important role in many strands of normative political thought, and are especially crucial to climate change politics, this is a remarkable oversight. It risks political theory being irrelevant to climate change mitigation. The implications of this oversight for political theory are explored here through an analysis of the liberalism-ecologism debate. The article argues that attempts to green liberalism – to move it beyond environmentalism – cannot succeed while liberalism is silent about technological change. More broadly, given that most political theory traditions make claims about technological change, claims crucial to their worldviews and normative goals, it argues that much more theorisation of the concept is necessary. Especially now that they shape how the world understands climate change mitigation, contests over the meaning of technological change are intensely political contests. Political theory needs to get much more involved.

Description: Renewable energy changes the geopolitics of energy: whereas access to fossil fuel resources were key in the past, control over technology and industry will be key in the future. Consequently, different scholars have predicted that a growing focus on renewables will increase or decrease conflict in the energy sector, with no consensus on which is most likely. Here, we investigate the degree of conflict in renewable energy technology (RET) trade by analyzing data on 7041 trade conflicts 1995–2020, guided by two sets of theory-driven hypotheses. We show that RET trade is associated with more, longer, and more intense trade conflicts than other trade conflicts for 1995–2016. This supports the neorealist, geo-economic view of countries being willing to risk conflict to increase their share of a market rather than avoiding conflicts to increase the overall market size. It also contradicts the view that renewables will reduce conflict: at least in the past and regarding trade, it has increased rather than decreased conflict. For 2017–2020, this trend is reversed and RET trade became significantly less conflictive than other trade. Our findings imply that improved conflict-resolution institutions for RET are needed. We also suggest establishing specific institutions to govern trade in immature technologies.

Description: Considering growing participatory turns in regulatory scientific risk analysis, this paper compares how social scientists use participatory and analytical methods to understand risk perceptions and meet competing demands for representativeness and inclusiveness. Drawing on case studies of how three European risk agencies use participatory and analytic methods in the context of biotechnology, it confirms difficulties of analytic methods to shed light on perceptions when applied to unfamiliar topics. It also shows the potential of participatory in particular deliberative formats to engage affected populations in the risk analysis process, despite challenges in promoting inclusiveness. The cases call for the integration of methods, while remaining aware of the need to understand the mutual interplay in the constructions of risks and structural inequalities.

Description: This study, performed under the umbrella of the Task Force on Hemispheric Transport of Air Pollution (TF-HTAP), responds to the need of the global and regional atmospheric modelling community of having a mosaic emission inventory of air pollutants that conforms to specific requirements: global coverage, long time series, spatially distributed emissions with high time resolution, and a high sectoral resolution. The mosaic approach of integrating official regional emission inventories based on locally reported data, with a global inventory based on a globally consistent methodology, allows modellers to perform simulations of a high scientific quality while also ensuring that the results remain relevant to policymakers. HTAP_v3, an ad-hoc global mosaic of anthropogenic inventories, has been developed by integrating official inventories over specific areas (North America, Europe, Asia including Japan and Korea) with the independent Emissions Database for Global Atmospheric Research (EDGAR) inventory for the remaining world regions. The results are spatially and temporally distributed emissions of SO2, NOx, CO, NMVOC, NH3, PM10, PM2.5, Black Carbon (BC), and Organic Carbon (OC), with a spatial resolution of 0.1 x 0.1 degree and time intervals of months and years covering the period 2000–2018 (DOI 10.5281/zenodo.7516361, https://edgar.jrc.ec.europa.eu/dataset_htap_v3). The emissions are further disaggregated to 16 anthropogenic emitting sectors. This paper describes the methodology applied to develop such an emission mosaic, reports on source allocation, differences among existing inventories, and best practices for the mosaic compilation. One of the key strengths of the HTAP_v3 emission mosaic is its temporal coverage, enabling the analysis of emission trends over the past two decades. The development of a global emission mosaic over such long time series represents a unique product for global air quality modelling and for better-informed policy making, reflecting the community effort expended by the TF-HTAP to disentangle the complexity of transboundary transport of air pollution.

Description: Political conflicts about energy and climate change policies often have local implications, yet little is known about local public opinion towards these policies. Here, we estimate support towards 26 climate change mitigation policies for 402 German counties and for up to four points of time using multilevel regression and poststratification. We find that local support for climate policies varies by up to 60 percentage points across German counties with large disparities between the rural and urban population. While support for the expansion of wind power plants and solar power plants have converged over the last years, attitudes on the phase-out of coal power have polarized across regions. Using a spatial panel analysis, we find that support for the expansion of wind and solar plants correlate with the actual development of solar and wind capacities in these regions. Moreover, the spread of climate policy opinion is strongly determined by spatial diffusion as change in one region positively influences the trajectory of policy opinion among its neighbors.

Description: At the root of much of the deforestation, land rights violations, human rights abuses and ultimately the continuation of unequal, neocolonial North-South relations are the two-fold phenomena of global market pressures for extractivism and mass production of resources and the militarization of response to social conflicts created by these activities. We will investigate the ‘new’ extractivism economic activities from the perspective of the violence perpetrated by assemblages of power against indigenous protest movements in the Peruvian Amazon region. Specifically, we will probe a grassroots’ response to the way Peru’s elites have integrated the country within the global economic system: we focus on Indigenous peoples’ protests in 2008-9 against the new regulation to open the Amazon for development of resources by private companies carried out by Peru’s President Alan García, on the grounds that it represented a threat to their natural resources and livelihood.

Description: Stakeholder engagement has become increasingly important in energy research and is now even required by many funding agencies. Recent energy modelling projects also claim to involve stakeholders in the research process, although this is usually a process of one-way communication. This raises the question of the extent to which stakeholder involvement can have an impact on the modelling work, or whether it is often a case of mere ‘stakeholder-washing’ to meet funding requirements. In this discussion paper, I reflect on the experiences of stakeholder engagement in the EU Horizon 2020 project Sustainable Energy Transition Laboratory (SENTINEL), discuss the impacts of stakeholder participation on the energy modelling and unfold key challenges of involving stakeholders in energy modelling. I discuss that it worked well to engage stakeholders in defining user needs and discussing modelling results, while only a few stakeholders could be continuously involved through the project period. I also show that although the project successfully identified research questions and needs, the ability of models to answer questions was limited, and making models understandable to users remains a key challenge. Stakeholder engagement in SENTINEL was more than ‘stakeholder-washing’: it led to the identification of user needs and research questions, impacted scenario design, modelling improvements and the development of new modelling tools, and enabled critical reflection on modelling approaches and results. Finally, I make nine recommendations for future stakeholder engagement in energy (modelling) research that can enable mutual learning and enhance the legitimacy, relevance and impact of modelling. The further development of multi-stakeholder communities of practice around innovative energy modelling approaches can facilitate the transition to climate neutrality.

Description: This chapter provides a review of Germany’s ambitious import-oriented hydrogen strategy. It places the German policy approach in the context of its broader Energiewende (energy transition) strategy, aimed not only at a transition of Germany’s energy and industrial system to carbon neutrality by 2045 but also at the promotion of the German Energiewende approach abroad. The chapter begins by providing a short review of the German Energiewende policy legacy, relating it to it emerging hydrogen policy. On this basis, it provides a comprehensive review of Germany’s National Hydrogen Strategy (NHS) with a particular focus on its outward-oriented elements. It discusses Germany’s external hydrogen policy along the following five dimensions: political dialogue and diplomacy (both bilateral and multilateral); interventions aimed at building international supply chains; cooperation in research and innovation; capacity building and skill development; and activities aimed at addressing questions of sustainability. The chapter closes with discussion of key strengths and weaknesses of the strategy and highlights areas for its further development. While Germany's outward-oriented approach is identified as an important strength of the strategy, it could place greater emphasis on cooperation with partners in the EU. Moreover, collaboration with partner countries, both in- and outside the EU, should go beyond the relatively narrow focus on the promotion of hydrogen production and trade. Rather, it should take a broader perspective, aimed at promoting competitive and resilient industrial value chains centered on the EU and its policy and regulatory model. In particular, countries in the European Neighborhood represent important partners in such a strategy. Broadening the scope of cooperation with these countries will also increase the incentives for these countries to engage in partnership development. Finally, the chapter points out that Germany has taken an ambiguous stance on the role that blue hydrogen should play in a future hydrogen economy. While its strategy comes out strongly in favor of green hydrogen, it is also pursuing partnerships for the import of blue hydrogen. This has resulted in a mismatch. While analytical capacities and standardization-related activities are being advanced for green hydrogen production, the government also needs to clearly define its stance on blue hydrogen imports and develop the needed analytical tools and policy instruments for this purpose.

Description: The UK aims to become a leader in green industries by developing a competitive hydrogen industry, bringing new jobs, and revitalizing peripheral areas of the country. Hydrogen is also seen as an opportunity for the country to improve its energy security, as extracting fossil fuels is increasingly costly and unfeasible given the UK’s decarbonization goals. Its hydrogen strategy takes a “twin track” approach, that is, simultaneously promoting hydrogen from gas with carbon capture and hydrogen from low-carbon electricity. The UK strategy focuses on the importance of applying hydrogen to industry including chemicals, steel, and glass. However, its funding and research initiatives rather place an emphasis on developing local hydrogen markets by using hydrogen for heating and transportation. In the short term, the UK aims to develop “blue” hydrogen, which is perceived as cheaper, to replace household gas use. Funding for hydrogen innovation comes from the government, but revenue support is likely to be funded by levies on energy consumption. This approach seems unlikely to result in the green industrial leadership the government hopes to achieve. The unwillingness of the government to take strategic decisions on hydrogen types and uses means that its funding is stretched across different cases. And, while the UK participates in international standard-setting initiatives to better participate in global markets, it is not officially coordinating with or investing in hydrogen infrastructure that could connect it with Europe and thereby enable regional hydrogen trade. Given the rise in industrial policy measures including for hydrogen in the US and EU, the UK’s goal of becoming a major hydrogen player seems unlikely without a significant change in policy clarity and ambition.

Description: Multi-technology auctions are a popular instrument to support renewable electricity in the European Union. While they increase competition, some technologies could dominate, which might be an issue for some countries’ power system reliability. Using statistical methods, I analyse how balanced or skewed European multi-technology auctions are and investigate driving factors. I show that 80% of all multi-technology auction rounds from 2011 to 2020 were skewed, strongly or exclusively favouring one technology. None of the investigated design elements and general context factors can explain this. Instead, specific auction-external context factors may better explain the observed skewness. Furthermore, the aggregated outcome across all rounds, years, and countries is relatively balanced because the rounds are differently skewed. This could be coincidental and change in the future if outcomes remain strongly skewed. Policymakers may consider shifting to technology-specific auctions that target single technologies, particularly if they cannot manage the risks of skewed auction outcomes. Thereby, they promote a diverse and targeted deployment of renewables.

Description: This report provides a comprehensive review of China’s emerging hydrogen economy with a particular focus on policy and regulation, both at the national and sub-national level. China’s promotion of the hydrogen sector is emblematic of its broader efforts to promote greenhouse gas reductions, while pursuing ambitious industrial development goals and promoting energy security. To date, industrial policy goals have clearly taken center stage, with a particular focus on fuel cell vehicles. For now, China is pursuing a diversified strategy in support of hydrogen supply, which includes all different types of hydrogen production, including coal-based hydrogen. Nevertheless, policy documents increasingly emphasize the potential of renewable hydrogen as a vehicle for stabilizing an electricity system based on variable renewable energy as well as broader decarbonization efforts. They also increasingly highlight the need to transition to an exclusively renewable hydrogen supply in the future. In a number of cases, local-level strategies have come out more strongly in support of renewable hydrogen than current central government policies. Local-level policy has also played a key role in the promotion of fuel cell vehicles. Policies for hydrogen-based decarbonization of industry are only at a nascent stage. Similarly, China’s ambitions to promote hydrogen storage and transport remain at a relatively early stage of development with an important emphasis on the promotion of innovation and acquisition of technological know-how. Finally, both China’s hydrogen strategy and the engagement of its energy SOEs do not appear to be strongly motivated by considerations of geopolitics at this stage. To be sure, Chinese officials are considering increasing opportunities for investment in hydrogen projects around the world. In this vein, the national hydrogen development plan considers the importance of the Belt and Road Initiative (BRI) for promoting hydrogen-related standards and investments. Beyond these geoeconomic considerations, the role of hydrogen as a future energy commodity and its geopolitical implications do not figure prominently in Chinese policy efforts. Indeed, due to China’s relative abundance of renewable energy resources, it is does not exhibit major vulnerabilities related to the future provision of hydrogen. Conversely, hydrogen could even offer an opportunity to reduce its energy dependence in the future. This and other efforts to shape global hydrogen trade do not seem to be a significant driver of its policy efforts, however.

Description: This wholly new edition of the Handbook provides an authoritative examination of international law relating to the protection of the marine environment. Chapters critically engage with current legal issues surrounding activities that harm the marine environment, including marine pollution, seabed activities, exploitation of marine biodiversity and climate change, and with the different legal tools and mechanisms, including environmental impact assessments and compliance and dispute settlement mechanisms, used to protect the marine environment. New chapters also address legal issues relating to the role of technology and marine scientific research as well as the application of principles such as public participation.

Description: Evaluating the embodied environmental impact of solar photovoltaic (PV) technology has been an important topic in addressing the sustainable development of renewable energy. While monetization of environmental externality is a remaining issue, which should be carried out in order to allow for an easy-to-understand comparison between direct economic and external cost. In this study, the environmental impact of solar PV power is monetized through conversion factors between midpoint and endpoint categories of life cycle analysis and the monetization weighting factor. Then, the power generation capacity and generation life of PV and coal-fired power plants are assumed to be consistent in order to compare the total cost of PV and coal-fired power generation. Results show that the cost of PV technology is higher than coal-fired in 2026 to 2030, taking into account environmental external costs and production costs. However, by 2030, the total cost of coal-fired power will be higher than that of solar PV. The life span cost per kWh is $3.55 for solar PV and $116.25 for coal-fired power. Although solar PV power seems more environmentally effective than coal-fired power in the life span, our results reveal the high environmental external cost of producing solar photovoltaic modules, which reminds us to pay more attention to the environmental impact when conducting cost-benefit analysis of renewable technologies. Without incorporating the environmental cost, the real cost of renewable technology will be underestimated.

Description: Italy presents, potentially, some important comparative advantages in the emerging clean hydrogen economy. However, unlike other large EU countries, Italy has not yet issued a comprehensive strategy on hydrogen nor has it developed a coherent hydrogen diplomacy. It was only with the National Recovery and Resilience Plan, launched in the wake of the COVID-19 crisis, that Italy upgraded its measures for promoting green hydrogen and related activities. The main players in the Italian hydrogen landscape are national industrial actors, especially state-owned energy companies. This leading role can be an important asset to overcome the problems related to an industrial system otherwise composed of small and medium companies, which can find it difficult to compete with hydrogen frontrunners. Externally, Italy has supported all the European and multilateral initiatives on hydrogen, although in the EU the country is a policy-taker rather than a policy-shaper. The main focus of the Italian international approach is linked to the hydrogen hub concept, which targets the MENA region and is also supported by its national energy companies. This concept has received a further push after the beginning of the war in Ukraine. However, its practical realization is very problematic because of domestic and external challenges.

Description: Die deutsche Gesellschaft ist in den letzten Jahren einer Vielzahl von schweren Krisen ausgesetzt. Risikoforscher:innen sprechen hier von Polykrisen. Erst kam Corona, dann kamen die weiteren Auswüchse der Klimakrise beispielsweise in Form von Überschwemmungen und Waldbränden, der Krieg in der Ukraine, Nahrungsmittelkrisen in der Welt, Inflation, galoppierende Energiepreise und es werden täglich mehr.

Description: Sustainability projects are being promoted around the world with a large dose of spectacle, including those in the Arabian Peninsula where governments have invested heavily in large greening projects and events. This article examines these spectacular projects in the United Arab Emirates (UAE), which are typically dismissed by Western observers as mere PR and ‘greenwashing.’ Moving past this simplistic critique, I contextualize ‘sustainability spectacle’ as a broad cultural phenomenon, with deep roots in Western countries. Based on ethnographic research on sustainability events, sites, and initiatives in the UAE, I show how ‘post-oil’ greening initiatives use sustainability spectacle to promote a positive narrative about the ‘modern’ national self, and reflect the growing international imperative to be green.

Description: The European Green Deal (EGD) represents the most ambitious environmental policy framework in European history, aimed at improving the health and well-being of citizens and future generations through climate action and becoming the first climate-neutral region in the world by 2050. The EC has initiated the European Democracy Action Plan and the European Climate Pact to include the participation of citizens in a meaningful way to help achieve these goals (i.e. not simply a tokenistic gesture or box-ticking exercise). While these efforts to ensure greater citizen participation and deliberation in environmental policy are good first steps, there is still a lack of clarity about what meaningful citizen engagement should look like. This paper will propose that for such efforts to be successful, we need to assess different perspectives in the debate and provide recommendations based on this. This paper provides a systematic review of various approaches within the academic literature on citizen participation and deliberation in environmental policy (ecocentrism, biocentrism, ecomodernism, ecofeminism, environmental pragmatism, environmental citizenship, environmental rights, and environmental justice). Following this, we provide a list of 16 criteria (in five thematic sections) for policymakers, civil society organisations (CSOs), and society, to ensure meaningful citizen participation and deliberation.

Description: Extracting these minerals would be energy intensive and the problems experienced in terrestrial mining would be replicated at sea

Description: Digitalisation is widely believed to aid societies and economies in managing crises, for instance by facilitating remote work. However, there is limited evidence of the extent to which digitalisation has improved social and economic performance of industry in the COVID-19 crisis. This paper examines correlations between three socio-economic indicators of resilience, and digital intensity of industry sectors in Germany between 2020 and previous years. We find that sectors with higher digital intensity experienced greater stock market volatility, but also a faster recovery, in 2020. However, less digitalised sectors seem to have performed better in terms of sectoral value added and employment. Thus our descriptive analysis challenges the prevailing positive framing of the impact of digitalization and raises the hypothesis that less digitalised sectors may carry benefits for resilience in the economy. Our analysis also emphasises the crucial role of the public sector and public funding in promoting resilience. We conclude with recommendations on how to design industrial and digital policies for green and socio-economically resilient economies.

Description: The transition toward renewables is central to climate action. The paper empirically tests whether renewables also enhance international peace, a hypothesis discussed in the International Political Economy (IPE) of renewables literature. It develops and tests hypotheses about the pacifying effects of renewables, with a view to establishing the foundations for analyzing more detailed causal mechanisms. These mechanisms rest on the ‘energy democracy’ debate, suggesting that a low carbon world sees less interstate tension thanks to more states being democratic; the ‘capitalist peace’ theorem, establishing that the deployment of renewables brings about economic development, reducing conflict; and the human security literature, positing that renewables reduce local-level reduce vulnerabilities, thus enhancing social stability and reducing violence. Using a longitudinal dataset on global renewable energy investment, econometric tests suggest that distributed renewable energy systems do not seem to foster democratic rule, nor do they have a significant influence on human development. Countering the energy democracy literature, it is a higher concentration of renewable investment that tends to increase stability/ absence of violence and human development, instead of decentralized investment patterns. We find no evidence for the ‘peace through prosperity’ argument. Overall, there is no support for the assumption that renewables bring about peace and reduce conflict. The paper critically discusses the limitations of these findings and suggests further avenues for empirical research.

Description: Low concentrations of pollutants may already be associated with significant health effects. An accurate assessment of individual exposure to pollutants therefore requires measuring pollutant concentrations at the finest possible spatial and temporal scales. Low-cost sensors (LCS) of particulate matter (PM) meet this need so well that their use is constantly growing worldwide. However, everyone agrees that LCS must be calibrated before use. Several calibration studies have already been published, but there is not yet a standardized and well-established methodology for PM sensors. In this work, we develop a method combining an adaptation of an approach developed for gas-phase pollutants with a dust event preprocessing to calibrate PM LCS (PMS7003) commonly used in urban environments. From the selection of outliers to model tuning and error estimation, the developed protocol allows to analyze, process and calibrate LCS data using multilinear (MLR) and random forest (RFR) regressions for comparison with a reference instrument. We demonstrate that the calibration performance was very good for PM1 and PM2.5 but turns out less good for PM10 (R2 = 0.94, RMSE = 0.55 μg/m3, NRMSE = 12 % for PM1 with MLR, R2 = 0.92, RMSE = 0.70 μg/m3, NRMSE = 12 % for PM2.5 with RFR and R2 = 0.54, RMSE = 2.98 μg/m3, NRMSE = 27 % for PM10 with RFR). Dust events removal significantly improved LCS accuracy for PM2.5 (11 % increase of R2 and 49 % decrease of RMSE) but no significant changes for PM1. Best calibration models included internal relative humidity and temperature for PM2.5 and only internal relative humidity for PM1. It turns out that PM10 cannot be properly measured and calibrated because of technical limitations of the PMS7003 sensor. This work therefore provides guidelines for PM LCS calibration. This represents a first step toward standardizing calibration protocols and facilitating collaborative research.

Description: There are various approaches to facilitation in deliberative mini-publics, yet the scholarly literature remains relatively underdeveloped in identifying which approaches to facilitation are useful in achieving certain deliberative goals. This article compares facilitation approaches based on their potential to achieve different deliberative goals by examining three cases of deliberative mini-publics on urban transformations in the German city of Magdeburg. All three mini-publics were given the same task but were implemented using a particular approach to facilitation: (1) self-organized; (2) a multi-method approach; and (3) dynamic facilitation. We analyzed video recordings and surveys conducted among participants and found that differences in facilitation influence the process of deliberation in numerous ways. While deliberation can happen without a facilitator, certain deliberative goals can be better achieved when the process is professionally facilitated. More stringent or involved facilitation, however, may not serve every purpose of deliberation equally. There are trade-offs when designing, convening, or facilitating deliberative processes, and no approach fits all mini-publics. We conclude the article by identifying the implications of our findings for the scholarship and practice of citizen deliberation in structured forums and beyond.

Description: The complexity and importance of environmental, societal, and other challenges require new forms of science and practice collaboration. We first describe the complementarity of method-driven, theory-based, and (to the extent possible) validated scientific knowledge in contrast to real-world, action-based, and contextualized experimental knowledge. We argue that a thorough integration of these two modes of knowing is necessary for developing ground-breaking innovations and transitions for sustainable development. To reorganize types of science–practice collaborations, we extend Stokes’s Pasteur’s quadrant with its dimensions for the relevance of (i) (generalized) fundamental knowledge and (ii) applications when introducing (iii) process ownership, i.e., who controls the science–practice collaboration process. Process ownership is a kind of umbrella variable which comprises leadership (with the inflexion point of equal footing or co-leadership) and mutuality (this is needed for knowledge integration and developing socially robust orientations) which are unique selling points of transdisciplinarity. The extreme positions of process ownership are applied research (science takes control) and consulting (practice takes process ownership). Ideal transdisciplinary processes include authentic co-definition, co-representation, co-design, and co-leadership of science and practice. We discuss and grade fifteen approaches on science–practice collaboration along the process ownership scale and reflect on the challenges to make transdisciplinarity real.

Description: Policy advice for dealing with major crises has focussed on two concepts: resilience and sustainability. The article introduces the term resilience and explains its application in different disciplines. Furthermore, it explores the relationship between resilience and sustainability, illustrates the various concepts that are associated with each term and suggests an integrative approach that is based on the ideal of maintaining critical services for reaching humane living conditions for present and future generations based on fair distribution rules and inclusive governance processes.

Description: Sustainability transformations in the energy industry, a key sector in the race to a zero-carbon economy in the Anthropocene, are still being largely understood from a technological standpoint. We propose that the question of how energy transitions can perform for societies and local communities should move to the centre of the debate, in order to unlock untapped social opportunities of transitioning to renewable energy and to speed up climate action. This article draws on four inter-related research perspectives which have made a considerable contribution to conceptualising social performance: sustainability, climate action, business, and development. Understanding and connecting these four perspectives in a transdisciplinary manner is important in our understanding of what Social Performance means in the real world. It also helps to make the concept applicable and transformational. Against this background we propose a community-centred and participatory social performance approach to energy transitions.

Description: Aerosol optical properties were studied over Chisinau in Moldova, one of the longest running AERONET sites in Eastern Europe. During two decades (September 1999–November 2018), the mean aerosol optical depth (AOD) and Angstrom exponent (AE) were observed as 0.21 ± 0.13 and 1.49 ± 0.29, respectively. The highest AOD (0.24 ± 0.13) and AE (1.60 ± 0.26) were observed during the summer. More than half (∼55%) of the share was occupied by clean continental aerosols with seasonal order of winter (74.8%) 〉 autumn (62%) 〉 spring (48.9%) 〉 summer (44.8%) followed by mixed aerosols with a respective contribution of 30.7% (summer), 28.4% (spring), 22.5 (autumn) and 16.4% (winter). A clear dominance of volume size distribution in the fine mode indicated the stronger influence of anthropogenic activities resulting in fine aerosol load in the atmosphere. The peak in the fine mode was centered at 0.15 μm, whereas that of the coarse mode was centered either at 3.86 μm (summer and autumn) or 5.06 μm (spring and winter). ‘Extreme’ aerosol events were observed during 21 days with a mean AOD (AE) of 0.99 ± 0.32 (1.43 ± 0.43), whereas ‘strong’ events were observed during 123 days with a mean AOD (AE) of 0.57 ± 0.07 (1.44 ± 0.40), mainly influenced by anthropogenic aerosols (during 19 and 101 days of each event type) from urban/industrial and biomass burning indicated by high AE and fine mode fraction. During the whole period (excluding events days), the fine and coarse mode peaks were observed at the radius of 0.15 and 5.06 μm, which in the case of extreme (strong) events were at 0.19 (0.15) and 3.86 (2.24) μm respectively. The fine mode volume concentration was 4.78 and 3.32 times higher, whereas the coarse mode volume concentration was higher by a factor of 1.98 and 2.27 during extreme and strong events compared to the whole period.

Description: The Global CO2 Initiative hosted the 2023 TEA/LCA Workshop on Harmonizing CCU Assessments on May 16-18. This fifth workshop in the series was planned and conducted by the International CCU Assessment Harmonization Group with members from the USA (GCI at U-M, NETL, NREL, ANL), Canada (NRC), Germany (RIFS, formerly known as IASS), Switzerland (ETH Zürich), and Japan (NIAIST). This team works to advance transparent and uniform assessments of CCU technologies and products. These workshops have traditionally engaged a broad audience in breakout sessions to debate, resolve, and define key issues with assessments in CCU. Note that occasionally, it makes sense to include border aspects and include assessments of CO2 sequestration into the discussions. Hence, in some sections, the mention of CCUS is included. The focus topics for 2023 had been selected to address social aspects and standardization. 51 on-site and up to 265 remote attendees spent one-and a-half days in lively discussions. This report presents a summary of the breakout session discussions, key status descriptions, and open issues.

Description: Energy transformations not only evoke multi-dimensional claims for just distribution, recognition, and procedures, but also reveal how these claims depend on and shape the spatial context that they address. The aim of this contribution is to provide a framework that connects spatial and multi-dimensional aspects of justice in energy transition research. It builds on literature in the fields of just transition studies and energy justice. While the relevance of considering space and scale in socio-technical transitions is widely acknowledged, a conceptual framework can help to connect justice and spatiality in transitions and support scrutiny of their interconnections. The present work seeks to address this gap by incorporating contributions from the fields of political geography and political theory. Accordingly, it discusses central intersections in the moral–spatial tension field. Spatial justice claims are conceptualized as referring at the same time to moral (substance-related) and spatial dimensions of (in)justice and relating both to each other. The paper conceptualizes how justice claims refer to multiple scales, center-periphery relations, interterritorial and infrastructure-related concerns as well as to place-based attachments. It discusses the positioning of actors in this moral-spatial field as well as the reference to directional patterns of responsibility and effect. Attention to spatial justice claims further discloses processes of boundary construction, perpetuation, and contestation as well as the regional entrenchment of widely shared justice claims. Transformation-related political institutions and processes in affected regions reveal how various spatial justice claims are publicly related to each other.

Description: New particle formation (NPF) and subsequent particle growth are important sources of condensation nuclei (CN) and cloud condensation nuclei (CCN). While a number of observations have shown positive contributions of NPF to CCN at low supersaturation, negative NPF contributions were often simulated. Using the observations in a typical coastal city of Qingdao, we thoroughly evaluate the simulated number concentrations of CN and CCN using a NPF-explicit parameterization embedded in WRF-Chem model. In terms of CN, the initial simulation shows large biases of particle number concentrations at 10–40 nm (CN10–40) and 40–100 nm (CN40–100). By adjusting the process of gas-particle partitioning, including mass accommodation coefficient of sulfuric acid, the phase changes of primary organic aerosol emissions and the condensational amount of nitric acid, the concomitant improvement of the particle growth process yields a substantial reduction of overestimates of CN10–40 and CN40–100. Regarding CCN, SOA formed from the oxidation of semi-volatile and intermediate volatility organic vapors (SI-SOA) yield is an important contributor. In the original WRF-Chem model with 20 size bins setting, the yield of SI-SOA is too high without considering the differences in oxidation rates of the precursors. Lowering the SI-SOA yield results in much improved simulations of the observed CCN concentrations. On the basis of the bias-corrected model, we find substantial positive contributions of NPF to CCN at low supersaturation (~0.2 %) in Qingdao and over the broad areas of China, primarily due to the competing effects of increasing particle hygroscopicity surpassing that of particle size decrease. This study highlights the potentially much larger NPF contributions to CCN on a regional and even global basis.

Description: Ground-based observational characterization of atmosphere aerosols over Central Asia is very limited. This study investigated the columnar aerosol characteristics over Issyk-Kul, Kyrgyzstan, a background site in Central Asia using the long-term (∼14 years: August 2007–November 2021) data acquired with the Cimel sunphotometer. The mean aerosol optical depth (AOD) and Ångström exponent (AE) during the observation period were 0.14 ± 0.10 and 1.19 ± 0.41, respectively. Both AOD and AE varied across seasons, with highest AOD in spring (0.17 ± 0.17). Regarding the aerosol types, clean continental aerosols were dominant type (65%), followed by mixed aerosols (∼19%), clean marine aerosols (∼14%), dust (0.8%), and urban/industrial and biomass burning aerosol (0.7%). The aerosol volume size distribution was bimodal indicating the influence of both anthropogenic and natural aerosols with clear dominance of coarse mode during the spring season. Mainly dust and mixed aerosols were present during high aerosol episodes while the coarse mode aerosol volume concentration was 7.5 (strong episodes) and ∼19 (extreme episodes) times higher than the whole period average. Aerosol over this background sites were from local and regional sources with some contribution of long-range transport.

Description: Ecological modernization is the policy-driven innovation and diffusion of resource efficient clean technologies. It has become an extremely dynamic process – nothing less than a global industrial revolution. Ecological modernization has also been highly effective as far as disruptive technologies such as renewable energy, e-mobility, or certain water-related technologies are concerned; a new area being bio-technical innovations in agriculture and forestry. There are also several economic co-benefits which increase the political feasibility of policies under the ecological modernization paradigm. Its present performance nevertheless needs a differentiated assessment: its environmental improvements so far have been typically selective and mainly restricted to market-based solutions. Often it coexists with the older “dirty” structures (such as the fossil fuel sector) instead of fully replacing or transforming them. There are also problems of equity regarding the attribution of costs or the global distribution of benefits. The strengths and weaknesses of ecological modernization will be exemplified by the pioneer case of Germany. To overcome the weaknesses of ecological modernization it is necessary to proceed to structural solutions regarding economic sectors, infrastructures, land use, and even lifestyles. The political system’s capacity for environmental policy must be strengthened to allow for the adoption of necessary policies with a lower degree of feasibility. Instruments such as strategic investment, cooperative approaches, and mechanisms of compensation will become important in an advanced strategy of ecological modernization (ecological modernization 2.0). In addition, the traditional idea of sufficiency could be revived as a general supporting guideline, with new policy instruments and a more selective focus on the consumption of resource-intensive products and services.

Description: The establishment of thresholds is integral to environmental management. This paper introduces the use of thresholds in the context of deep-seabed mining, a nascent industry for which an exploitation regime of regulations, standards and guidelines is still in the process of being developed, and for which the roles and values of thresholds have yet to be finalised. There are several options for integrating thresholds into the International Seabed Authority's regulatory regime, from being stipulated in regulations to being part of a mining contract, each option having its own advantages and disadvantages. Here we explore the range of ways that thresholds can be derived, set out the challenges in translating ecological and management data into thresholds, highlight factors for acceptance and operationalisation of thresholds in deep-seabed mining, and explain the necessity of refining thresholds as knowledge on impacts to features improves. Some comparable marine industries already use thresholds and these could potentially be used as starting points for the development of thresholds for deep-seabed mining. In order to be acceptable to the wide range of deep-seabed mining stakeholders, thresholds need to strike a balance among levels of harm acceptable by society, levels of environmental precaution justifiable by governments, scientific robustness, and operational practicality.

Description: Ocean Census is a new Large-Scale Strategic Science Mission aimed at accelerating the discovery and description of marine species. This mission addresses the knowledge gap of the diversity and distribution of marine life whereby of an estimated 1 million to 2 million species of marine life between 75% to 90% remain undescribed to date. Without improved knowledge of marine biodiversity, tackling the decline and eventual extinction of many marine species will not be possible. The marine biota has evolved over 4 billion years and includes many branches of the tree of life that do not exist on land or in freshwater. Understanding what is in the ocean and where it lives is fundamental science, which is required to understand how the ocean works, the direct and indirect benefits it provides to society and how human impacts can be reduced and managed to ensure marine ecosystems remain healthy. We describe a strategy to accelerate the rate of ocean species discovery by: 1) employing consistent standards for digitisation of species data to broaden access to biodiversity knowledge and enabling cybertaxonomy; 2) establishing new working practices and adopting advanced technologies to accelerate taxonomy; 3) building the capacity of stakeholders to undertake taxonomic and biodiversity research and capacity development, especially targeted at low- and middle-income countries (LMICs) so they can better assess and manage life in their waters and contribute to global biodiversity knowledge; and 4) increasing observational coverage on dedicated expeditions. Ocean Census, is conceived as a global open network of scientists anchored by Biodiversity Centres in developed countries and LMICs. Through a collaborative approach, including co-production of science with LMICs, and by working with funding partners, Ocean Census will focus and grow current efforts to discover ocean life globally, and permanently transform our ability to document, describe and safeguard marine species.

Description: Governments and international organizations are increasingly using public funds to mobilize and leverage private finance for climate projects in the Global South. An important international organization in the effort to mobilize the private sector for financing climate mitigation and adaptation in the Global South is the Green Climate Fund (GCF). The GCF was established under the UNFCCC in 2010 and is the world’s largest dedicated multilateral climate fund. The GCF differs from other intergovernmental institutions through its fund-wide inclusion of the private sector, ranging from project design and financing to project implementation. In this paper, we investigate private sector involvement in the GCF through a qualitative exploratory research approach. We ask two main questions: Do private sector projects deliver on their ambitious goals? What are the tensions, if any, between private sector engagement and other principles of the GCF (most importantly the principles of country ownership, mitigation/adaptation balance, transparency, and civil society participation)? This paper argues that private sector involvement does not provide an easy way out of the financial constraints of public climate financing. We show that the GCF fails to deliver on its ambitious goals in private sector engagement for a number of reasons. First, private sector interest in GCF projects is thus far underwhelming. Second, there are strong tradeoffs between private sector projects and the Global Partnership for Effective Development Co-operation (GPEDC) principles of country ownership, transparency, and civil society participation. Third, private sector involvement is creating a mitigation bias within the GCF portfolio. Fourth, while the private sector portfolio is good at channeling funds to particularly vulnerable countries, it does so mostly through large multi-country projects with weak country ownership. Fifth, there is a danger that private climate financing based on loans and equity might add to the debt burden of developing countries, destabilize financial markets, and further increase dependency on the Global North.
