Beschreibung: 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.

Beschreibung: This spatio-temporal dataset contains capacity factors timeseries for locations on a grid with 50km edge length in Europe. The data is resolved in one hour timesteps and comprises the years 2000--2016. It has been generated using Renewables.ninja and is based on MERRA-2 reanalysis data. For each of the ~2700 onshore location, it contains one time series for onshore wind turbines and five time series for PV installations with different orientations and tilts. PV time series exist for (1) installations on open fields, (2) installations on all possible rooftops, (3) south-facing and flat rooftops, (4) east- and west-facing rooftops, (5) north-facing rooftops. For each of the ~2800 offshore location there is one timeseries for offshore wind turbines. Two GeoTIFF files contain spatial information of onshore and offshore locations. For each of the three technologies -- onshore wind, offshore wind, and PV -- there is one NetCDF file determining the temporal dimension and containing the data. The GeoTIFF and NetCDF files are linked through unique IDs for all locations. This data serves as input data to euro-calliope, a model of the European electricity system.

Beschreibung: Gegen das Projekt eines (Europäischen) Green Deal beschwört die populistische Rechte die Dystopie einer drohenden Öko-Diktatur. Welche Rolle spielt diese dystopische Denkfigur im politischen Diskurs? Für wen ist dieses Zukunftsbild glaubwürdig? Wie lässt sich die darin ausgedrückte Zukunftsangst kritisieren? Der Beitrag behandelt diese Fragen aus ideologiekritischer, utopietheoretischer und diskursanalytischer Perspektive.

Beschreibung: Aerosol radiative properties using recently available high-quality columnar aerosol data collected at several AERONET sites in South Asia, with a focus on pollution outflow from continental South Asia observed over Hanimaadhoo in Maldives, a small island in northern Indian Ocean are quantified. The seasonal mean aerosol optical depth (AOD) over Hanimaadhoo is ≥ 0.3 (except ca. 0.2 during monsoon season), and single scattering albedo (SSA) is 〉 0.90 in all seasons. Fine mode aerosols contribute dominantly to AOD. SSA decreases as a function of wavelength due to influence of continental aerosols, except during the monsoon season when its spectral trend reverses due to increase in dust. Carbonaceous aerosols dominate (〉90%) contribution to absorption AOD (AAOD). Black carbon (BC) and brown carbon (BrC) contribute 〉75% and 〈25%, respectively, to AAOD due to carbonaceous aerosols. The observed seasonal mean aerosol radiative forcing at the surface (ARFSFC), at the top of the atmosphere (ARFTOP) and in the atmosphere (ARFATM) is 〉 −25 Wm-2, 〉−20 Wm-2 and ~+20 Wm-2, respectively. Aerosol loading and atmospheric heating have increased over this background site over the last decade. A regional-scale analysis of aerosol properties and radiative effects across and surrounding the Indo-Gangetic Plain (IGP) shows that AOD is ≥ 0.3 over entire region, and aerosols reduce seasonally 30–50 Wm-2 of solar radiation reaching the surface, contributing significantly to solar dimming effect. The atmospheric solar heating rate due to aerosols (HR) is ≥ 1 K day−1 across IGP. These high ARFs, ARFESFC and HR, and increasing trends have significant implications to climate and hydrological cycle over South Asia and beyond.

Beschreibung: Marine Ökosysteme wie Mangrovenwälder, Seegraswiesen, Salzwiesen und Makroalgen sowie marine Sedimente verfügen über die Eigenschaft, Kohlenstoff in ihrer Biomasse und Sedimenten zu speichern. Durch die Rehabilitation, Wiederherstellung und den Schutz dieser Ökosysteme kann somit das Potential des Ozeans zur Aufnahme von atmosphärischem CO2 erhöht werden. Dieses Potential wurde in Vorbereitung der 15. UN-Klimakonferenz in Kopenhagen 2009 unter dem Konzept „Blue Carbon" eingeführt und wird seitdem weiter erforscht und in politischen Prozessen weiterentwickelt. Die langfristige Sequestrierung von atmosphärischem CO2 durch Blue-Carbon-Ökosysteme unterstützt Umsetzungsprozesse zur Erreichung der Ziele des Pariser Abkommens. Das über Blue-Carbon-Ökosysteme sequestrierte CO2 zählt als Teil der globalen Kohlenstoffsenke als „negative Emissionen". So erreichte negative Emissionen sollten jedoch nicht zur Umgehung von ohnehin notwendigen politischen und wirtschaftlichen Schritten in Richtung einer CO2-neutralen Zukunft führen. Die Wiederherstellung und Rehabilitation von Blue-Carbon-Ökosystemen zur Erhöhung der natürlichen Kohlenstoffsenke des Planeten sollte zusätzlich zu einer signifikanten globalen Emissionsreduktion eingesetzt werden. Diese Studie erörtert die wissenschaftlichen, ökonomischen und politischen Fortschritte im Bereich Blue Carbon und stellt mögliche politische Handlungspfade vor, die das Potential von Blue-Carbon-Ökosystemen zum Klimaschutz in, durch und mit Deutschland stärken. Für die verschiedenen Blue-Carbon-Ökosysteme wird aufgezeigt, inwiefern die Ausweitung und der Schutz dieser Ökosystemen weitere Ziele der Klimaanpassung und der nachhaltigen Entwicklung unterstützen. Aufbauend auf einer Auswertung praktischer Umsetzungsbeispiele von Blue-Carbon-Projekten und möglicher Finanzierungsmechanismen wird nachfolgend ein politischer Handlungsleitpfaden für Deutschland in Bezug auf Blue Carbon entwickelt. Die politischen Handlungsempfehlungen wurden gemeinsam mit dem Bundesministerium für Umwelt, Naturschutz und Nukleare Sicherheit entwickelt.

Beschreibung: Marine ecosystems like mangroves forests, seagrass meadows, salt marshes and macroalgae can store carbon in their biomass and sediments. Rehabilitation, restoration and conservation of these ecosystems can increase the potential for atmospheric carbon uptake by the ocean. This concept was first introduced as ‘blue carbon’ during the preparation for the 15th UN Climate Change Conference in Copenhagen in 2009 and since then it has seen continuous incorporation into politics and research. The long-term sequestration of atmospheric CO2 via blue carbon ecosystems supports the 1.5°C goal of the Paris Agreement. The CO2 that is sequestered by blue carbon ecosystems is part of the global carbon sink and therefore it can be counted as ‘negative emissions’ in the global carbon stocktake. However, such negative emissions should not be implemented as a substitute for necessary political and economic measures towards a carbon neutral future. Rehabilitation and restoration of blue carbon ecosystems as a natural carbon sink is one of many measures but cannot replace the significant reduction of global emissions needed for the realisation of the global climate targets. This study discusses the scientific, economic and political realm of blue carbon. Furthermore, possible courses for political action “in”, “by”, and “through” Germany that could strengthen the potential of blue carbon ecosystems to sequester carbon are explored. The study investigates a variety of blue carbon ecosystems to determine to what extent the expansion and conservation of blue carbon ecosystems can support additional climate adaptation targets and Sustainable Development Goals. The evaluation of a multitude of implemented and ongoing blue carbon projects across the globe gives insight to best practices and possible financing mechanisms. A political guideline for Germany regarding blue carbon was developed together with the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

Beschreibung: You may have heard about minerals on the bottom of the ocean. The UK Government sponsors several exploration contracts for UK Seabed Resources (a subsidiary of the American aerospace and security company Lockheed-Martin) in the Pacific Ocean to look for them. These minerals come from the so-called ‘Area’, the deep seafloor beyond the limits of national jurisdiction and far out in the global ocean. This ‘Area’ and its mineral resources represent the ‘common heritage of mankind’. The Law of the Sea Convention, UNCLOS (1982) determines that rather than a free-for-all, this last piece of ocean floor outside the jurisdiction of any coastal state belongs to mankind as a whole and shall be administered in such a way that benefits all, considering in particular the needs of developing countries.

Beschreibung: Energy system models are advancing rapidly. However, it is not clear whether models are becoming better, in the sense that they address the questions that decision-makers need answered to make well-informed decisions. Therefore, we investigate the gap between model improvements relevant from the perspective of modellers compared to what users of model results think models should address. Thus, we ask: What are the differences between energy model improvements as perceived by modellers, and the actual needs of users of model results? To answer this question, we conducted a literature review, 32 interviews, and an online survey. Our results show that user needs and ongoing improvements of energy system models align to a large degree, so that future models are indeed likely to be better than current models. We also find mismatches between the needs of modellers and users, especially in modelling of social, behavioural and political aspects, the trade-off between model complexity and understandability, and the ways that model results should be communicated. Our findings suggest that a better understanding of user needs and closer cooperation between modellers and users is imperative to truly improve models and unlock their full potential to support the transition towards climate neutrality in Europe.

Beschreibung: There is a need to conduct more diverse cross‐case analyses in the Multiple Streams Approach (MSA) literature which originated in the United States, to show how key concepts, such as a windows‐of‐opportunity and the role of policy entrepreneurs, manifest in different political contexts. We apply Qualitative Comparative Analysis for a cross‐case analysis of a unique dataset representing 20 countries from four continents. This approach allows us to highlight distinct pathways to influencing policies. We identify four configurations for expanding civic spaces and two configurations for changing policies. We identify three findings novel to MSA: there are two distinctive policy entrepreneur roles involving local and international civil society actors; effective entrepreneurship is conditional on strengthening civic voice and creating civic space conducive to advocacy; and, therefore, effective entrepreneurs often must focus on expanding the civic space to discuss policy problems and the technical and political feasibility of policy solutions.

Beschreibung: In recent times, a significant number of studies on the composition and sources of fine particulate matters and volatile organic compounds have been carried out over Delhi, either initiated by or in association with the researchers from the Indian Institute of Technology Kanpur (IIT Kanpur), in collaboration with researchers from within and outside India. All these studies utilized highly time-resolved, campaign-mode observations made with state-of-the-art instrumentation during the late winter months (mid-January to March) of 2018. Individually, each of these studies were rigorous in nature, containing explicit detailing about different types of ambient air pollutants in Delhi such as organic aerosols, inorganic elements, metals, carbonaceous aerosols, and volatile organic compounds. This study consolidates the extremely useful knowledge on source attribution of these air pollutants in the Delhi National Capital Region currently contained in these fragmented studies, which is vital to further enhancing our understanding of composition, characteristics, and sources of air pollutants over Delhi, as well as to designing appropriate mitigation measures tailored to local specifics.

Beschreibung: The international health crisis has exposed a serious problem for energy systems – we’re not taking renewable energy technology seriously as a critical asset. Most solar panels today are made in China, and a shortage of key components means that Europe is now facing major delays in new installations. Wind power faces a double whammy – manufacturing is down, and countries may not have the personnel and parts locally to keep systems running. Countries should aim to build up national clean tech infrastructure in the same way that they ensure strategic reserves of fossil fuels.

Beschreibung: Public acceptance is central to the success of a transition agenda but with the increasing uptake of renewable energy technology, achieving and sustaining the public legitimacy for accelerating the energy transition is at risk. This study provides an updated account of the energy transition development in Germany and Australia with a focus on institutional legitimation. Drawing on the distinction between input and output legitimacy, we query how enabling community participation can enhance the legitimacy of policy instruments. We employ two case studies of energy transitions – those of Germany and Australia – to explain where and how community participation has supported the legitimacy of policy interventions. While input legitimacy remains high in both Germany and Australia, both examples illustrate how policy instruments can lack legitimacy if decision-makers lose sight of or never properly consider the output dimension of legitimacy.

Beschreibung: The Pan-Third Pole (PTP) owns complex geography and demographic features where aerosol roles and their impact cannot be neglected as it jeopardizes both the environment and human health. Therefore, we analyzed spatio-temporal aerosol concentration, the influence of meteorological conditions, and underlying aerosol transport mechanisms over the PTP by leveraging observation, satellite dataset, and model outputs. The observation and model simulation result showed that aerosol concentrations exceeded the world health organization (WHO) and China guideline values in most of the locations. This study revealed distinctive seasonality with the highest and lowest aerosol concentrations during the winter and summer seasons, respectively, which could be favored by meteorological conditions and emissions from biomass burning. In response to higher aerosol concentrations, the maximum aerosol optical depth (AOD) values were observed over the major hotspot regions however, interestingly summer high (AOD 〉 0.8) was observed over the Indo Gangetic Plain (IGP) in South Asia. The columnar aerosol profile indicated that the higher aerosol concentrations were limited within 1–2 km elevation over the densely populated regions over South Asia and Eastern China. However, the significant aerosols concentrations found to be extended as high as 10 km could potentially be driven by the deep convection process and summer monsoon activities. Regionally, the integrated aerosol transport (IAT) for black carbon (BC) and organic carbon (OC) was found to be maximum over SA. Noticeable OC IAT anomaly (~5 times 〉 annual mean) found during spring that was linked with the biomass burning events. Yet, the dust transportation was found to be originated from the arid land and deserts that prolonged especially during summer followed by spring seasons. This study highlights the driver mechanism in aerosol seasonality, transport mechanism, and further motivates the additional assessment into potential dynamic relation between aerosol species, aerosol atmospheric river, and its societal impact.

Beschreibung: Ariadne-Forschende haben deshalb auf Grundlage von zwei bundesweit durchgeführten Panel-Umfragen die Zustimmung von 26 Klimaschutzmaßnahmen auf regionaler Ebene geschätzt und dabei geographische und zeitliche Meinungsunterschiede sichtbar gemacht. Die Ergebnisse der Forschenden verdeutlichen regionale Unterschiede in der Zustimmung zu einzelnen Klimaschutzmaßnahmen, die sich vor allem zwischen Stadt- und Landbevölkerung sowie Ost- und Westdeutschland zeigen.

Beschreibung: Transport is the problem child of climate policy (see Haas & Richter 2020, Der Verkehr. Das Sorgenkind der Klimapolitik, in: POLITIKUM 2, 46-53). While emissions reductions have been achieved across every other sector since 1990, transport-related emissions have climbed by 3.7 percent between 1990 and 2018.

Beschreibung: This study assesses the impacts of fossil-fuel power plants in Turkey on people’s health. It quantifies the cobenefits of decarbonising Turkey’s power sector with renewable energy for unburdening Turkey’s health system, in terms of health cost savings and reduction in premature deaths. This research study has been carried out in the context of the COBENEFITS project, which assesses a range of socio-economic co-benefits of renewable energy, in addition to the benefits of reducing energy sector greenhouse gas emissions, when compared to conventional energy systems.

Beschreibung: Das DiDaT Weißbuch ist das Ergebnis eines zweijährigen transdisziplinären Prozesses der Identifikation, Erkundung und Analyse der Probleme und Lösungsoptionen bei der Erfassung, Behandlung, Verwertung und Nutzung digitaler Daten. Das Projekt DiDaT hat sich zum Ziel gesetzt, die zentralen Auswirkungen und Nebenwirkungen („Unseens“ genannt), die sich aus den „Wechselwirkungen des Besitzes/Eigentums, des ökonomischen Wertes, der Nutzung und dem Zugang zu digitalen Daten“ ergeben, zu erforschen, deren Wirkungen zu bewerten und Orientierungen zur Entwicklung von Strategien zu entwickeln, die Personen, Unternehmen, und anderen sozialen Akteuren einen angemessenen Umgang mit möglichen unerwünschten Effekten zu ermöglichen.

Beschreibung: Durch die ambitionierten Klimaschutzziele Deutschlands und der EU nimmt der Dekarbonisierungsdruck auf die ganze Gesellschaft zu, insbesondere auf die Industrie. Liefer- und Wertschöpfungsketten ändern sich und müssen gleichzeitig angepasst werden. Das Diskussionspapier fasst die Ergebnisse einer Workshopreihe zusammen, die die dena gemeinsam mit dem IASS Potsdam und der Stiftung Arbeit und Umwelt der IGBCE im Herbst 2021 zu diesem Thema durchgeführt hat. Es analysiert Chancen und Herausforderungen der anstehenden Veränderungen und identifiziert relevante Handlungsfelder für die Politik.

Beschreibung: We analyze long-term aerosol and precipitable water vapour (PWV) properties at two high-altitude sites (Nainital and Hanle) over the central Himalayan and western Trans-Himalayan region from 2008 to 2018. First-time assessment of the seasonality and variation in combined aerosol and water vapour radiative effects are also attempted, aiming to investigate the atmospheric effect on solar radiation over the Himalayan range that is especially important for the regional climate. A synergy of ground-based measurements from sun photometers, GPS (Global Positioning Systems) observations, radiosondes, along with satellite and reanalysis data was used to examine inter-annual and seasonal variability of PWV and specific humidity over both sites. The PWV is highest in monsoon and much lower during the dry winter season with slightly higher values at Nainital compared to Hanle. This is due to the lower altitude (∼2 km amsl) of Nainital, which is also directly affected by the Indian summer monsoon, compared to the Trans-Himalayan region. The vertical profiles of PWV from satellite and reanalysis data reveal a great consistency on a seasonal basis. The PWV is considered as one of the main greenhouse gases that exhibits a positive radiative effect at the Top of the Atmosphere (TOA) in the order of about 10 W m−2 at Nainital and 7.4 W m−2 at Hanle. The atmospheric radiative effect due to water vapour is about 3–4 times higher compared to aerosols, resulting in atmospheric heating rates of 0.94 and 0.96 K Day−1 at Nainital and Hanle, respectively. The results highlight the importance of water vapour and aerosol radiative effects in the climate sensitive Himalayan range.

Beschreibung: Many teams have developed a wide range of numerical or categorical indicators of progress in the implementation of the SDG targets. But these indicators cannot identify why target goals have not been accomplished, whether or how they do or do not do justice to the social and cultural context in which they are applied, and how newly emerging social dynamics affect indicators. Nor do they provide means for resolving conflicting values and making balanced trade-offs. Our starting point in examining why we have not been successful in progressing towards sustainability is that the sustainability conundrum is primarily a societal, rather than an environmental problem. Our present emphasis is to maintain our way of life while minimizing its impact, hoping that such a minimization strategy would make the world more sustainable. Reducing for example the extent of pollution but keeping the same industries alive would not be sufficient for a transformation towards sustainability. Instead we should ask “How did we come to this point and what practices, in our societies and in our science, need to change to make progress towards sustainability?” To answer these questions, one needs to go much further back than usual in the history of western societies to identify the societal, scientific, technological and environmental co-evolutionary dynamics that have brought us to the current conundrum. And the fact that most societal challenges are of the “wicked” kind, as well as the need to decide among many societal options and many future pathways that may lead to positive results require that we seriously engage in using “Complex Systems” approaches. It is up to our scientific community to identify these pathways, and we need to move fast!

Beschreibung: Translating the agricultural eco(logical)-intensification model to European aquaculture hosts the potential for sustainably providing local food for local communities. Using online and printed surveys, we investigated the relationship between social factors such as age, gender, and education to seafood consumption behavior and the perception of aquaculture production. The frequency of seafood consumption was significantly lower in young and female respondents, whereas respondents with a higher level of education consume more frequently. Furthermore, high-frequency seafood consumers had a significant preference for wild-caught fish. Young and female respondents also perceived sustainability of aquaculture lower, whereas the level of education had a significantly positive relation to the attitude towards aquaculture. To foster the acceptance of eco-intensified aquaculture production, we suggest that communication efforts need to be group-tailored, focusing on the reduced environmental impacts, increased animal welfare, and novel products like seaweed to meet the values of the German consumer groups.

Beschreibung: Over 30% of the world’s population lives within 100 km of the oceanic coast. More than three billion people rely on fishing and other ocean-related livelihoods. The ocean is a biodiversity hotspot and moderates the climate, having absorbed around 40% of the world’s total carbon emissions. Oceanscapes provide an essential cultural good, offer recreational opportunities, health benefits, artistic inspiration and an entire cosmology and way of life for indigenous communities. However, anthropogenic pressures have seriously impacted the ocean and threaten its ability to provide human societies with the required climatic and ecosystem conditions for life on earth. The German G7 presidency has proposed a G7 “Ocean Deal” for the sustainable use, protection and effective governance of the ocean and its resources. Several ongoing global ocean governance processes require strong multilateral leadership and close alignment between the G7, in particular in this period of serious international tensions following the Russian invasion of Ukraine. At the One Ocean Summit in February 2022, global leaders have put forth first commitments to make 2022 a decision year for the ocean. Building on the final declaration of the summit and the UK G7 Ocean Decade Navigation Plan, we highlight that a G7 “Ocean Deal” should include provisions for 1) ambitious ocean governance to safeguard ocean health and climate (in the G7’s own waters and through leadership in international settings), 2) improving ocean observation, data infrastructure and knowledge sharing, and 3) financing the transition towards more sustainable interactions with the ocean. Specifically, we recommend that G7 states: 1a. Eliminate national subsidies that contribute to overfishing and push to finalize the related WTO agreement; step up international cooperation, financial & technical assistance to prevent IUU fishing. 1b. Reduce marine debris through a comprehensive global agreement on plastic pollution. 1c. Pause deep sea mining until risks are better understood and a transparent, inclusive and accountable institutional structure is in place that guarantees the effective protection of the marine environment. 1d. Expand marine protected areas in line with the proposed goal of at least 30% by 2030, and accelerate work in the coming months to successfully finalize negotiations for a legally binding instrument to conserve and sustainably use marine biological diversity in areas beyond national jurisdiction (BBNJ). 1e. Fully recognize the importance of the ocean-climate nexus and strengthen the ocean dimension in key climate negotiations. 2a. Adopt a legal framework and binding commitments for a sustained and shared global coordination of ocean observations and infrastructure on marine data, compliant with FAIR and CARE principles. 2b. Ensure long-term, guaranteed funding, clear institutional affiliations, coordinated and integrated data products to enable continuous, comprehensive observations supporting policy monitoring & evaluation 3a. Redesign and scale up ocean finance by increasing funding of early-stage, nature-positive and science-based opportunities, and large-scale investment into zero-carbon, resilient and nature-based coastal blue infrastructure, and by integrating ocean criteria into sustainability finance frameworks (EU Taxonomy, Task Force on Climate-related Financial Disclosures (TCFD), Taskforce for Nature-related Financial Disclosures (TNFD)).

Beschreibung: Modern societies are confronted with ‘systemic risks’ which challenge conventional risk analysis and management. The phrase ‘systemic risks’ denotes risk phenomena which are exceedingly complex and interdependent. Systemic risks originate in tightly coupled systems. They are characterised by cascading effects, tipping points and non-linear developments. Furthermore, compared to their potential impacts, they often lack proportional public awareness and adequate policies. Conventional risk management struggles with these challenges. Yet many threats to modern society, such as financial crises and the impacts of anthropogenic climate change, match these attributes. This article investigates the concept of systemic risks and raises questions for governance. The concept of inclusive risk governance serves as a guiding principle. In particular, the article draws on the Risk Governance Framework by the International Risk Governance Council to address the challenges of systemic risks.

Beschreibung: Die Bundesregierung hat den Kohleausstieg bis zum Jahr 2038 beschlossen und beschleunigt so die Transformation in den Kohleregionen. Die Ausgangslagen für den Wandel in den Revieren und umliegende Gemeinden der Lausitz und des Rheinlands sind dabei sehr unterschiedlich. In beiden Regionen stehen Politik, Zivilgesellschaft, Wirtschaft und Wissenschaft vor der Aufgabe, Lösungspfade und Transformationskorridore zu finden, die ökologisch verantwortlich, sozial gerecht, wirtschaftlich vielversprechend und demokratisch getragen sind. Das IASS Potsdam veranstaltete im Frühjahr 2020 gemeinsam mit dem Kulturwissenschaftlichen Institut Essen einen Workshop, um demokratiepolitische Gemeinsamkeiten und Unterschiede im Strukturwandel der Braunkohleregionen herauszuarbeiten. Die Zwischenergebnisse werden in dieser Studie dargestellt.

Beschreibung: Background: Ambient air pollution poses a major risk for the development and aggravation of respiratory diseases. Evidence suggests that even in low-level air pollution environments there is a risk for an increase in adverse respiratory symptoms. We examined whether variations in daily air pollution levels of nitrogen dioxide, ozone, or particulate matter in Berlin, Germany were associated with hospital admissions of chronic obstructive pulmonary disease (COPD) and asthma patients in a time series analysis. Methods: We calculated single and multi-pollutant models, investigated possible lags in effect, and analysed the influence of meteorological variables on the results. Data from January 2005 through December 2015 were used to quantify the concentration–response. Results: The risk ratio for asthma patients to be hospitalised on the same day of NO2 exposure was 1.101 per 10 µg/m3 NO2 increase (95% CI: 1.013 to 1.195), for COPD patients 1.123 (95% CI: 1.081 to 1.168). Neither the exposure to ozone (95% CI: 0.904 to 1.020), PM10 (95% CI: 0.990 to 1.127), nor PM2.5 (95% CI: 0.981 to 1.148) was associated with an increased risk ratio for asthma patients to be hospitalised. Risk ratios for the hospital admission of COPD patients were also not increased due to ozone (95% CI: 0.981 to 1.033), PM10 (95% CI: 0.988 to 1.032), or PM2.5 (95% CI: 0.966 to 1.019) exposure. The presented risk ratios and confidence intervals relate to the day of exposure. We found no increased hospitalisation risks with a delayed occurrence on subsequent days. Conclusions: A quantifiable, statistically significant increase in risk for asthma and COPD exacerbations owing to NO2 exposure at levels well below European regulatory limit values was observed.

Beschreibung: This IASS study takes an in-depth look at Covid-19's impacts on the global energy sector, and then zooms in to the country level to see individual country effects and responses. The case studies are compiled by energy researchers in Argentina, China, Germany, India, Israel, and the United States.

Beschreibung: The EU’s Carbon Border Adjustment Mechanism (CBAM) is expected to launch in October 2023, with reporting obligations only. The scheme aims to ensure that European efforts to reduce greenhouse gas emissions do not induce so-called ‘carbon leakage’, which could occur if companies based in the EU relocate carbon-intensive production to countries with less ambitious climate standards or increase imports of carbon-intensive products to the EU. The mechanism will require companies importing certain products to the EU to offset embedded GHG emissions by purchasing CBAM certificates, thus ensuring that the carbon price of imported products is equivalent to that of products made by European producers under the EU Emissions Trading Scheme (ETS). CBAM’s effectiveness and impact will be evaluated by the EU towards the end of its phase-in period. This evaluation will likely lead to adjustments in the mechanism’s design and will be followed closely by third countries considering the introduction of similar instruments. Economies and sectors dependent on exports to the EU will be both more exposed and vulnerable to the mechanism. In this policy brief we explore the views of stakeholders in South Africa, the EU’s largest trading partner in Africa, and consider measures necessary to ensure that CBAM addresses issues of justice and sustainability. In particular we identify three key recommendations for European policymakers.

Beschreibung: People living or working in the Arctic are faced with uncertainty regarding future social, political, economic, and environmental change. This uncertainty is due not least to the ongoing transformations caused by climate change. This paper presents results from a project entitled “Yamal 2040: Scenarios for the Russian Arctic”, which employed ‘Strategic Foresight’, a specific co-design and engagement methodology, to support stakeholders of one particular region in the Arctic, the Yamal-Nenets Autonomous Okrug (Yamal region) in Western Siberia, Russia. It was the project’s objective to respond to this situation of general uncertainty, to develop forward-looking scenarios to better understand the risks and opportunities associated with future transformations in the Arctic. The findings presented here may be of interest for stakeholders in other parts of the Arctic and Russia that depend on the exploitation of fossil fuels and/or are facing complex and uncertain situations.

Beschreibung: The marine environment, subject to multiple pressures, is transboundary by nature. For ocean management and conservation, there is a need of enhanced collaboration and cross-sectoral solutions. This project aimed to develop a participatory dialogue platform that strengthens cooperation within and between marine regions in line with the 2030 Agenda. The “Marine Regions Forum” brings together stakeholders for joint learning and exchange of good practices, developing recommendations or building of partnerships across sectoral and territorial boundaries. The report shows that the informal format of the "Marine Regions Forum" can complement global discussions and regional efforts alike and thus support processes of ocean governance.

Beschreibung: 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.

Beschreibung: Economic disruption associated with the Covid-19 pandemic and the current energy and – potentially economic – crisis related to the war in Ukraine emphasize the importance of understanding and managing crises’ immediate and lasting effects on decarbonisation. Theory shows that the expected effects of crises are contested and could be supportive or detrimental to decarbonisation. This article examines the timing and mechanisms for how countries peak emissions and whether such peaks are related to economic crises. We empirically investigate the timing of CO2 emissions peaks in OECD and G20 countries 1965-2019, and the effects of major economic crises on the activity-related and structural drivers of emissions. We show that in all but two countries that have peaked emissions, the peak occurred just before or during a recession, by the combined effect of lower GDP growth and decreasing energy and/or carbon intensity during and after the crisis. In peak-and-decline countries, crises have typically magnified pre-existing improvements in energy and carbon intensities. Almost all peaking countries have returned to economic growth post-crisis, implying that structural change – not lost economic activity – was the critical driver of emission peaks. In non-peaking countries, the GDP growth was less affected, and structural change effects were weaker or rather increased emissions. Crises do not automatically trigger peaks but may strengthen ongoing decarbonisation trends through several mechanisms.

Beschreibung: Aerosol emissions from human activities are extensive and changing rapidly over Asia. Model simulations and satellite observations indicate a dipole pattern in aerosol emissions and loading between South Asia and East Asia, two of the most heavily polluted regions of the world. We examine the previously unexplored diverging trends in the existing dipole pattern of aerosols between East and South Asia using the high quality, two-decade long ground-based time series of observations of aerosol properties from the Aerosol Robotic Network (AERONET), from satellites (Moderate Resolution Imaging Spectroradiometer (MODIS) and Ozone Monitoring Instrument (OMI)), and from model simulations (Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2). The data cover the period since 2001 for Kanpur (South Asia) and Beijing (East Asia), two locations taken as being broadly representative of the respective regions. Since 2010 a dipole in aerosol optical depth (AOD) is maintained, but the trend is reversed—the decrease in AOD over Beijing (East Asia) is rapid since 2010, being 17% less in current decade compared to first decade of twenty-first century, while the AOD over South Asia increased by 12% during the same period. Furthermore, we find that the aerosol composition is also changing over time. The single scattering albedo (SSA), a measure of aerosol’s absorption capacity and related to aerosol composition, is slightly higher over Beijing than Kanpur, and has increased from 0.91 in 2002 to 0.93 in 2017 over Beijing and from 0.89 to 0.92 during the same period over Kanpur, confirming that aerosols in this region have on an average become more scattering in nature. These changes have led to a notable decrease in aerosol-induced atmospheric heating rate (HR) over both regions between the two decades, decreasing considerably more over East Asia (− 31%) than over South Asia (− 9%). The annual mean HR is lower now, it is still large (≥ 0.6 K per day), which has significant climate implications. The seasonal trends in AOD, SSA and HR are more pronounced than their respective annual trends over both regions. The seasonal trends are caused mainly by the increase/decrease in anthropogenic aerosol emissions (sulfate, black carbon and organic carbon) while the natural aerosols (dust and sea salt) did not change significantly over South and East Asia during the last two decades. The MERRA-2 model is able to simulate the observed trends in AODs well but not the magnitude, while it also did not simulate the SSA values or trends well. These robust findings based on observations of key aerosol parameters and previously unrecognized diverging trends over South and East Asia need to be accounted for in current state-of-the-art climate models to ensure accurate quantification of the complex and evolving impact of aerosols on the regional climate over Asia.

Beschreibung: 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.

Beschreibung: A survey of members of a scientific society focused on risk analysis suggests substantial support for seeing their scientific society pursue the communication goal of “trying to ensure that policymakers consider scientific evidence.” Support for pursuing this goal was largely predicted by researchers’ beliefs that it was ethical for the society to pursue the goal, that it would be satisfying to see their society pursue the goal, and the belief that the society could have a positive impact on society by pursuing the goal. Normative beliefs about pursuing the goal and organizational efficacy beliefs were not good predictors of goal support. Goal support was measured using a direct measure of perceived goal importance as well as measures focused on the degree to which respondents wanted their society to put resources into providing members with opportunities to pursue the goal and the amount of funding that members thought the society should devote to pursuing the goal. The theory underlying the work argues that we can treat science communicators’ choices about communication goals, objectives, and tactics as “planned behaviors” and thus study them using traditional behavior change models.

Beschreibung: This report is about the arts in the world after this. The world after COVID-19, the world after colonialism and globalization, the world after the digitization of society, and the world after climate change. In other words, itis about the arts in the world after the Enlightenment: a time in history when it was assumed we could reduce the world to objective facts, predict the behaviours of natural systems, and intervene in life bit by bit, in ways that would secure the results we desired and eliminate the ones we did not. Today, the world of linear, causal relationships governed by prediction and control is giving way to a world of emergence and inherent unpredictability. What does this have to do with art, you may wonder? More, I believe, than we can begin to imagine, yet just enough to recognize an opportunity, and prepare.

Beschreibung: Citizens’ assemblies are relatively new political institutions that enable a randomly-selected group of everyday people to deliberate and make collective recommendations on climate policy and action. This raises significant questions about their legitimacy and the extent to which they resonate with the public and other societal actors. This research brief draws on evidence from climate assemblies and other participatory and deliberative processes, as well as targeted interviews, to evaluate what we already know about perceptions of legitimacy and resonance and the factors that are likely to shape these perceptions. Drawing on these findings, the brief considers what actions can be taken for assemblies to maximise their legitimacy and resonance.

Beschreibung: We investigated the role of the passive volcanic plume of Mount Etna (Italy) in the formation of new particles in the size range of 2.5–10 nm through the gas-to-particle nucleation of sulfuric acid (H2SO4) precursors, formed from the oxidation of SO2, and their evolution to particles with diameters larger than 100 nm. Two simulations were performed using the Weather Research and Forecasting Model coupled with chemistry (WRF-Chem) under the same configuration, except for the nucleation parameterization implemented in the model: the activation nucleation parameterization (JS1 = 2.0 × 10−6 × (H2SO4)) in the first simulation (S1) and a new parameterization for nucleation (NPN) (JS2 = 1.844 × 10−8 × (H2SO4)1.12) in the second simulation (S2). The comparison of the numerical results with the observations shows that, on average, NPN improves the performance of the model in the prediction of the H2SO4 concentrations, newly-formed particles (~2.5–10 nm), and their growth into larger particles (10–100 nm) by decreasing the rates of H2SO4 consumption and nucleation relative to S1. In addition, particles formed in the plume do not grow into cloud condensation nuclei (CCN) sizes (100–215 nm) within a few hours of the vent (tens of km). However, tracking the size evolution of simulated particles along the passive plume indicates the downwind formation of particles larger than 100 nm more than 100 km far from the vent with relatively high concentrations relative to the background (more than 1500 cm−3) in S2. These particles, originating in the volcanic source, could affect the chemical and microphysical properties of clouds and exert regional climatic effects over time.

Beschreibung: 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.

Beschreibung: 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.

Beschreibung: The challenges facing European regions undergoing structural transformations as they transition towards sustainable development pathways have attracted increasing interest in recent years. Straddling the border between Germany and Poland, Lusatia is experiencing considerable transformation pressure. Various domestic and European funding programmes, for example under the umbrella of the European Green Deal, are intended to cushion the impacts of the phase-out or reduction of coal-fired power generation. The recently adopted EU Just Transition Mechanism aims to support sustainable structural transformations and the broader goal of achieving climate neutrality by mitigating impacts on the workforce and contributing to the diversification of economies in the most affected areas. Funds made available through this mechanism should be deployed in consultation with regional stakeholders in Lusatia to complement national support measures. Further funding programmes are available targeting various policy areas and could be harnessed to strengthen integration throughout the region. Funding programmes that are centrally managed by the European Commission (i.e. not under shared management with national governments) are of particular interest in this context. Closer political and economic cooperation, coupled with a deeper exchange of experience, can accelerate regional integration and guide processes of structural transformation towards sustainable outcomes. However, there are some practical hurdles to overcome in border regions. The primary objectives in using available EU funding are to mitigate the social impacts of processes of structural transformation and to deliver a just transition at all levels. Measures funded through these programmes should be aligned with the sustainable development goals (SDGs) and contribute to the goal of achieving climate neutrality.

Beschreibung: In den vergangenen sechs Jahrzehnten sind Natur, Umwelt und wissenschaftliche Erkenntnisse über den Zusammenhang von Umweltschäden und Klimaveränderungen auf ein wachsendes Interesse der Öffentlichkeit gestoßen. Zivilgesellschaftliche Initiativen, die Umweltbewegung, Umweltverbände und zuletzt Fridays for Future mobilisierten mit ihrem Engagement zwar die (internationale) politische Ebene. Doch politische Maßnahmen müssen vielfältigen Interessen gerecht werden und bedürfen möglichst breiter gesellschaftlicher Akzeptanz, um Wirkung zu entfalten.

Beschreibung: Some scholars have labeled the financial structures that faced a run during the 2007-9 Financial Crisis as ‘shadow banking system’ and have connected it to the emergence of new monetary instruments. This was the starting point for thinking about various forms of private debt as ‘shadow money’. Since then several shadow money theories have emerged, with seemingly different conceptualizations of shadow money. We argue that, despite different terminology and intellectual ancestry, these theories generally agree on three key criteria that define shadow money. A financial instrument must be met by a demand that considers it an alternative to established forms of money, has to trade at par to higher-ranking forms of money and must be created through a swap of private debt certificates (IOUs). Based on these criteria, we look at four instruments to discuss how and under what conditions they correspond, or have corresponded, to those criteria. These are money market fund shares, overnight repurchase agreements, assetbacked commercial papers and foreign exchange swaps. We show that the disagreement over what instruments to count as shadow money lies in the level of strictness in applying those criteria on real-world financial instruments. If we are mathematically strict, none of the instruments can be categorized as shadow money. If we allow for more empirical variation, then all of the instruments correspond to the definition.

Beschreibung: Taking the early tissue culture experiments of Alexis Carrel in the 1910s–1930s as its example, the article explores the relationship between advances in biotechnological control over living matter and a holistic ontology of life, which stresses the temporal specificity of living things. With reference to Henri Bergson, Carrel argued that physiological time depends on an organism’s relationship to its milieu. By developing a laboratory apparatus and culture media, new objects of investigation could be made to live outside the organism and be brought to behave in novel temporal ways. In difference to recent biotechnological advances, like for example genome editing, which seek to ‘engineer’ living organisms by rebuilding them from their DNA up, then, early twentieth century interventionist laboratory practices were often linked to an understanding that biological plasticity results from organismic complexity and interactions between organism and milieu. These notions contributed to shaping laboratory apparatuses and techniques; they also helped to establish an understanding of environmental control that would allow for the production of novel ‘living things’.

Beschreibung: International authorities are increasingly recognizing that utilizing the carbon dioxide (CO2) emissions from various industries can assist strategies for mitigating climate change. In developing novel carbon capture and utilization (CCU) technologies they aspire to contribute to circular economy targets and reduce consumption of fossil‐based raw materials. However, the potential economic effects of CCU on industrial value chains remain unclear. Hence, this study investigates the economic expectations placed on those actors currently conducting research and development (R&D) in CCU. The aspired levels of economic performance are identified through a systematic literature review of 19 policy advice reports and 15 scientific papers. Qualitative directed content analysis is conducted, based on an R&D input–output–outcome system. First, we identify three relevant groups of value chain actors by clustering industrial sectors: (a) equipment manufacturers, (b) high‐emitting producers, and (c) producers of materials and fuels. Then, we derive a criteria list from the review. Finally, the analysis reveals how CCU innovations are anticipated to impact different industries: Equipment manufacturers could contribute to economic growth. For high‐emitting producers, CCU provides one option for “surviving” sustainability transitions. Meanwhile, material and fuel producers need to act as “problem solvers” by offering competitive ways of utilizing CO2. We conclude by identifying research gaps that should be addressed to better understand the economic and social dimensions of CCU and to increase the chances of such innovations contributing to broader sustainability transformations of industrial and energy systems.

Beschreibung: This report – Study on the socio-economic importance of areas beyond national jurisdiction (ABNJ) in the Southeast Atlantic region – aims to analyse the socio-economic importance of the ABNJ adjacent to the countries within the Abidjan Convention Area in West, Central and Southern Africa. It characterizes the socio-economic interests in ABNJ, underpinned by the ecosystem services concept, and the actual and potential social and economic outcomes (costs and benefits) associated with the conservation and use (exploitation) of marine resources, both in qualitative, and to the extent possible in quantitative terms. In this study, the term “socio-economics” is taken in a broad context to include the social aspects related to human well-being, livelihoods, impacts on communities, equity, socio-political systems, as well as economic ones. The analysis is based on an extensive literature review of scientific publications, articles, analysis of available data, stakeholder knowledge and experience, as well as expert opinion gathered through targeted interviews. It provides a narrative and forward-looking assessment of the key activities. The information presented is intend-ed to support decision-makers, including government officials, the private sector and other stakeholders to make informed decisions about ABNJ and weigh environmental, social and eco-nomic objectives, in the context of a new internationally binding treaty for the conservation and sustainable use of marine biological diversity beyond national jurisdiction, the BBNJ agreement. This report is part of a series of reports covering issues of ocean governance with a focus on the Southeast Atlantic (and Southeast Pacific) published under the STRONG High Seas project – Strengthening Regional Ocean Governance for the High Seas (June 2017 – May 2022).

Beschreibung: Kopenhagen ist eine der Städte mit der besten Fahrradinfrastruktur weltweit. Um zu verstehen, wie die dänische Hauptstadt das erreicht hat, lohnt sich ein Blick in ihre Vergangenheit. Nach Jahrzehnten der autogerechten Stadtplanung, vor der auch Kopenhagen nicht gefeit war, demonstrierten in den späten 1970er und frühen 1980er Jahren Zehntausende für mehr Radwege – mit Erfolg. Welche Rolle haben Diskurse und Erzählungen über das Fahrrad im Dänemark dieser Zeit gespielt, damit aus Kopenhagen die Fahrradstadt werden konnte, die sie heute ist? Und was können wir daraus lernen, um selbst die politische Förderung des Fahrrads als nachhaltiges Verkehrsmittel kommunikativ zu befördern? Diesen Fragen widmet sich das vorliegende Discussion Paper. Es untersucht drei repräsentative Korpora der auflagenstärksten Tageszeitungen Dänemarks aus den Jahren 1977, 1980 und 1983 mithilfe der im Projekt „Narrative der Nachhaltigkeit“ entwickelten „pentadischen“ Narrativanalyse. Das Ziel ist es, erfolgreiche Narrative für die Verkehrswende hin zu einer nachhaltigen urbanen Mobilität zu identifizieren.

Beschreibung: Concentrating Solar Power (CSP) offers flexible and decarbonised power generation and is one of the few switchable renewable technologies that can generate renewable power on demand. Today (2018), CSP only contributes 5 TWh to European electricity generation but has the potential to become an important generation asset for decarbonising the electricity sector within Europe as well as globally. This chapter examines how factors and key political decisions lead to different futures and the associated CSP use in Europe in the years up to 2050. In a second step, we characterise the scenarios with the associated system costs and the costs of the support policy. We show that the role of CSP in Europe depends crucially on political decisions and the success or failure of policies outside of renewable energies. In particular, the introduction of CSP depends on the general ambitions for decarbonisation, the level of cross-border trade in electricity from renewable sources and is made possible by the existence of a strong grid connection between the southern and northern European Member States and by future growth in electricity demand. The presence of other baseload technologies, particularly nuclear energy in France, diminishes the role and need for CSP. Assuming a favourable technological development, we find a strong role for CSP in Europe in all modelled scenarios: Contribution of 100 TWh to 300 TWh of electricity to a future European electricity system. The current European CSP fleet would have to be increased by a factor of 20 to 60 over the next 30 years. To achieve this, stable financial support for CSP would be required. Depending on framework conditions and assumptions, the amount of support ranges at the EU level from € 0.4 to 2 billion per year, which represents only a small proportion of the total support requirement for the energy system transformation. Cooperation between the Member States could further help reduce these costs.

Beschreibung: This study conceptualizes international monetary hierarchy by focusing on different mechanisms to supply emergency US-Dollar (USD) liquidity from the Federal Reserve (Fed) to non-US central banks. To this end, it takes on board insights of critical macrofinance and develops a model of the global financial architecture as a web of interlocking balance sheets.

Beschreibung: Ce rapport - Étude sur l‘importance socio-économique des zones situées au-delà de la juridiction nationale (ZAJN) dans la région de l‘Atlantique Sud-Est - vise à analyser l‘importance socio-économique des ZAJN adjacentes aux pays de la region de la Convention d‘Abidjan en Afrique occidentale, centrale et australe. Elle caractérise les intérêts socio-économiques dans les ZAJN, étayés par le concept de services écosystémiques, et les résultats sociaux et économiques réels et potentiels (coûts et bénéfices) associés à la conservation et à l‘utilisation (exploitation) des ressources marines, à la fois en termes qualitatifs et, dans la mesure du possible, en termes quantitatifs. Dans cette étude, le terme „socio-économique“ est pris dans un contexte large pour inclure les aspects sociaux liés au bien-être humain, aux moyens de subsistance, aux impacts sur les communautés, à l‘équité, aux systèmes socio-politiques, ainsi que les aspects économiques. L‘analyse se fonde sur une étude approfondie de publications et d‘articles scientifiques, sur l‘analyse des données disponibles, sur les connaissances et l‘expérience des parties prenantes, ainsi que sur l‘opinion d‘experts recueillie lors d‘entretiens ciblés. Elle fournit une évaluation narrative et prospective des activités clés. Les informations présentées ont pour but d‘aider les décideurs, y compris les responsables gouvernementaux, le secteur privé et d‘autres parties prenantes, à prendre des décisions éclairées sur les ZAJN et à peser les objectifs environnementaux, sociaux et économiques, dans le contexte d‘un nouveau traité international contraignant pour la conservation et l‘utilisation durable de la biodiversité marine audelà de la juridiction nationale, l‘accord BZAJN. Ce rapport fait partie d‘une série de rapports couvrant les questions de gouvernance des océans avec un accent sur l‘Atlantique du Sud-Est (et le Pacifique du Sud-Est) publiés dans le cadre du projet STRONG High Seas - Strengthening Regional Ocean Governance for the High Seas (juin 2017 - mai 2022).

Beschreibung: Inspired by a paper by Teseletso and Adachi (Miner Econ 8(10):21, 2021), the hypothesis regarding the declining grade of mined copper ore and its possible use as a guide to the future of ultimate recoverable resources (URRs) is tested. As a time axis, cumulative production is taken. Grades can be either grade of cumulative tonnage or annual production grade. Correlation can be linear (grade and tonnage) or semi-logarithmic (grade linear, tonnage logarithmic). We first show that the assumption that the highest correlation is the best guide to the future may be a fallacy. This is the linear correlation between grades of cumulative tonnage and cumulative tonnages since 1959, i.e., 85% of all copper mined historically with a near-perfect correlation approaching one (R2 = 0.97). This leads to implausibly low results of the URR, clearly demonstrating that this trend must shift in the future. Moreover, Teseletso and Adachi’s (Miner Econ 8(10):21, 2021) approach using a linear or semi-logarithmic correlation between annual grades with cumulative production leads to erroneous results. Here, the later the calculation of the correlation begins, the lower the extrapolated tonnages are at predetermined, postulated ultimate cutoff grades. This contradicts the accepted knowledge that with lower grades, the resource base is broadened—not narrowed. The only reasonable finding results from the correlation between linear grades of cumulative production with logarithmic cumulative production, i.e., the Lasky relationship, indicating a URR of 7.5 GT Cu, of which 6.7 GT remain to be mined, which is equivalent of close to 325 years of present production. The trend towards declining Cu grades with constant real Cu prices shows the potential for creative solutions for other metal as well.

Beschreibung: To combat global warming, industry needs to find ways to reduce its carbon footprint. One way this can be done is by re-use of industrial flue gasses to produce value-added chemicals. Prime example feedstocks for the chemical industry are the three flue gasses produced during conventional steel production: blast furnace gas (BFG), basic oxygen furnace gas (BOFG), and coke oven gas (COG), due to their relatively high CO, CO2, or H2 content, allowing the production of carbon-based chemicals such as methanol or polymers. It is essential to know for decision-makers if using steel mill gas as a feedstock is more economically favorable and offers a lower global warming impact than benchmark CO and H2. Also, crucial information is which of the three steel mill gasses is the most favorable and under what conditions. This study presents a method for the estimation of the economic value and global warming impact of steel mill gasses, depending on the amount of steel mill gas being utilized by the steel production plant for different purposes at a given time and the economic cost and greenhouse gas (GHG) emissions required to replace these usages. Furthermore, this paper investigates storage solutions for steel mill gas. Replacement cost per ton of CO is found to be less than the benchmark for both BFG (50–70 €/ton) and BOFG (100–130 €/ton), and replacement cost per ton of H2 (1800–2100 €/ton) is slightly less than the benchmark for COG. Of the three kinds of steel mill gas, blast furnace gas is found to be the most economically favorable while also requiring the least emissions to replace per ton of CO and CO2. The GHG emissions replacement required to use BFG (0.43–0.55 tons-CO2-eq./ton CO) is less than for conventional processes to produce CO and CO2, and therefore BFG, in particular, is a potentially desirable chemical feedstock. The method used by this model could also easily be used to determine the value of flue gasses from other industrial plants.

Beschreibung: This chapter introduces nature and the source of climate change and its effects on human society and natural systems. It discusses the role of sustainable energy in climate change mitigation and adaptation. It also highlights the global initiatives to move toward net-zero emission by mid-century.

Beschreibung: To achieve the ambitious but necessary climate targets set by the Paris Agreement, the IPCC model pathways for limiting global warming to 1.5°C compared to pre-industrial levels make apparent the need for safeguarding and enhancing the natural global carbon sink – including via carbon dioxide removal (CDR). A range of ocean-based CDR approaches, also termed “negative emissions technologies” (NETs), has been proposed to make use of the ocean’s potential to take up carbon dioxide from the atmosphere and store it in water, biomass, and sediments. The governance framework in place to regulate CDR in the ocean, at this time, is limited to the direct and articulate regulation of ocean fertilization. Meanwhile, other NETs such as ocean alkalinity enhancement and artificial upwelling emerge, but a comprehensive and foresight-oriented regulation for the testing or even deploying at larger scale is missing. Specifically, there is large uncertainty on unintended (positive and negative) effects of these technologies on the condition of the ocean, in addition to enhanced carbon uptake and storage, and how these may impede on or support other global sustainability goals. The deployment of NETs in the ocean poses additional governance complexities relating to unknowns, uncertainties, and transboundary issues. In a study that is part of the EU H2020-project OceanNETs, we explore to what extent the current global governance framework directly or indirectly regulates emerging ocean-based NETs and reflect on the particularities and requirements for their comprehensive governance. The analysis considers the gaps, challenges, needs, and opportunities for comprehensive governance of ocean-based NETs.

Beschreibung: The transformation of industrial production is one of the big challenges on the pathway to sustainable development. Therefore, expectations regarding the contribution of Industry 4.0 are high. So far there is only little research focusing on the relation between the Sustainable Development Goals (SDGs) of the United Nations 2030 Agenda and the digitalization of industrial processes. We argue that sustainability aspects must be an integral part of Industry 4.0 implementation to support a sustainable development. For that reason, the digital manufacturing concept itself must take essential characteristics of sustainability into account. Our analysis has investigated to what extent sustainability aspects are currently reflected in the most recognized articles about Industry 4.0. For that purpose, we have conducted a systematic literature review, in which we have analysed the top cohort of most frequently cited articles published after 2013 on GoogleScholar dealing with “Industry 4.0”. Our literature review reveals that the descriptions reflect many expectations and hopes while only few of them are evidence-based. According to our results Industry 4.0 mainly deals with the economic dimension of sustainability such as growth and productivity. Although there are expectations that Industry 4.0 creates a window of opportunity for a more sustainable production, we could not find evidence to support this idea. Instead of targeting a more sustainable production, many descriptions draw a picture in which Industry 4.0 processes run exactly as before, just in a digital way.

Beschreibung: In order to advance ongoing efforts in the (still emerging) field of marine restoration, different forms of knowledge must be combined: not only the biological and technical aspects, but also the social and cultural dimensions of marine restoration efforts. This calls for a newly combined array of methods that allows for a bridging of these different knowledge dimensions. Drawing on our experiences from the ongoing knowledge transfer processes of the INTERNAS project (Scientific Transfer of the results of INTERNational Assessments in the field of Earth and Environmental Research into the German policy context), we provide an overview of methods that were used to link global recommendations with localized marine restoration schemes and policy options. Using a mixed methods approach, we were able to capture and understand the pathways of knowledge transfer from globally synthesized scientific knowledge to local realities related to protecting and enhancing marine biodiversity in Germany. With this structured knowledge transfer approach, actionable solutions for marine conservation and restoration activities could be tailored to the specific national and regional circumstances. Using participatory methods, framework conditions like ecological, social, legal, and sectoral value judgment dimensions can be identified. This allows for the development of concerted solutions and creates a common ground for good governance towards marine restoration. When scientists engage not only as experts but also as reflexive facilitators in such participatory processes, it is ensured that more inclusive forms of knowledge are fostered that are necessary to better anticipate the potentials and likely pitfalls that marine restoration efforts may encounter. We conclude that existing knowledge on ecosystems, their goods and services as well as societal expectations need to be understood from the onset in any kind of marine restoration effort.

Beschreibung: Este reporte tiene como objetivo evaluar la con-tribución al bienestar humano de las activida-des socioeconómicas, actuales y potenciales, en las áreas marinas fuera de la jurisdicción nacio-nal (ABNJ por sus siglas en inglés) del Pacífico Sudeste, destacando la dependencia humana de los servicios ecosistémicos que la biodiver-sidad marina en las áreas fuera de la jurisdic-ción nacional (o BBNJ por sus siglas en inglés) provee, así como también de aquellas activi-dades que compiten en uso o bien generan efectos negativos sobre ella como consecuen-cia de su desarrollo. El estudio se focaliza en los aspectos socioeconómicos que dependen de, e interactúan con, la BBNJ en la región FAO 87, correspondiente al área f rente a las áreas juris-diccionales de Chile, Perú, Ecuador y Colombia (países miembros de la Comisión Permanente del Pacífico Sur o CPPS1), y de manera general para el bienestar de la humanidad. Como parte de esta introducción, se presenta a continuación una primera subsección que provee de contexto en relación a la importancia de los ecosistemas marinos y la relación de la BBNJ con el bienestar humano, seguida por una segunda donde se describe la organización de este reporte.

Beschreibung: While the positive impacts of renewable energy development, the implementation and use of renewable energy for people and the planet are widely recognised, the direct contribution of local renewable energy projects to local community well-being has received limited attention. And while the Paris Climate Agreement and the 2030 Agenda for Sustainable Development, with its Sustainable Development Goals (SDGs), have been rightfully celebrated as global milestones towards securing livelihoods and opportunities now and in the future, they lack societal ownership and traction among communities, who are decisive in supporting and driving the necessary sustainability transformation. However, aside from energy access, the opportunities for local energy projects to provide broader positive effects (such as community revenues) through co-investments are largely regarded as secondary co-benefits, if not entirely ignored by development policies and practices. Tapping into these opportunities for effective policies and practices in climate action and international development calls for a different approach to sustainable energy development (energy transitions in some countries): a social performance approach to energy development and investment, which we outline in this paper. In the context of this paper, the social performance of energy sector investments refers to direct and positive social impacts on the well-being of individuals and communities during the development and implementation of energy projects and the usage of locally generated energy, in both monetary and non-monetary ways. In essence, the social performance approach in energy-sector investments and energy-project development puts the needs and well-being of people – both current and future generations – at the centre of energy development and related investments and activities. The social performance approach that we propose builds on the conceptual foundations of the capability approach, the co-benefits approach, the Need–Opportunity–Ability (NOA) model, and important groundwork on community development in South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP). An important aspect of the social performance approach is its focus on the direct contribution of these investments in fostering the well-being of individuals in a manner that reflects their aspirations for good quality of life. This approach can facilitate regular evaluation of progress and ensures accountability and adjustment of implementation strategies so that future investments, design, and implementation strategies perform both for people and the planet. Social performance can be used to compare how different energy options (e.g., a coal-mining site, a renewable wind park, or decentralised energy services such as solar mini-grids) may effectively and comprehensibly improve the lives of people and local communities. The social performance approach helps to identify concrete intervention points or enablers, to ensure and increase the positive contributions of energy-sector investments to the well-being of individuals and communities, either in monetary ways such as local economic value creation and employment, or in non-monetary ways such as community cohesion and social inclusion. In this paper we suggest that, consequently, policy interventions and investments aimed at decarbonising energy systems should not simply be monitored in view of how they perform for communities and people on the ground; rather, these interventions and investments should be intentionally designed to maximise their social performance for individuals and communities.

Beschreibung: The global transition to a low-carbon economy will significantly impact existing energy value chains and transform the production to consumption lifecycle, dramatically altering interactions among stakeholders. Thanks to its versatility, green hydrogen is gaining economic and political momentum and could play a critical role in a carbon-free future. Furthermore, its adoption will be critical for decarbonizing industrial processes at scale, especially hard-to-abate ones such as steel and cement production. Overall, hydrogen demand is expected to grow by 700% by 2050 (BP, 2019). Currently, the two central challenges to green hydrogen adoption and use at scale are limited infrastructure availability and cost. While recent spikes in fossil fuel prices due to the war in Ukraine have made green hydrogen cost-competitive with blue and grey hydrogen (Radowitz, 2022), from a long-term perspective, the International Renewable Energy Agency (IRENA) predicts a decline in green hydrogen costs by up to 85% by 2050 (IRENA, 2020), making it the dominant hydrogen form (IRENA, 2022).

Beschreibung: As a major contributor to climate change, the cement sector urgently needs to develop and implement greenhouse gas (GHG) mitigation technologies to drastically lower its emissions to reach carbon neutrality by 2050. Among the most promising technologies is CO2 mineralisation in which CO2 is transformed into a thermodynamically stable carbonate. CO2 mineralisation not only offers permanent storage of CO2 but also potentially avoids emissions by partially substituting conventional cement with the obtained carbonation products. Besides overcoming technical barriers, successful development and implementation of CO2 mineralisation require support from key stakeholders. While existing studies already provide technology-related data and assess CO2 mineralisation pathways, knowledge remains scarce about stakeholder priorities and perceptions. Using a multi-stakeholder expert survey, the present study examines: a) the priorities of different stakeholders in supporting CO2 mineralisation, b) their perceptions on the performance of CO2 mineralisation concepts, and c) their priorities if tasked with communicating CO2 mineralisation technologies to other groups. Hereby, we follow a multi-criteria decision analysis approach, based on an analytical hierarchy process, by comparing indicators from the three common sustainability pillars (i.e., environmental, economic, and social impacts). Our results indicate that key stakeholders strongly prioritise the health implications of CO2 mineralisation technologies and generally value social impacts highly. Hence, an in-depth research is needed to provide knowledge-based guidance on health issues and ways to fairly distribute costs and create positive employment outcomes. Additionally, stakeholders of all affiliations give second priority to reducing carbon footprint of cement, showing that they discount potential environmental and economic trade-offs associated with emission reduction goals. The results reveal that these concepts are perceived as compatible with other GHG mitigation approaches, such as carbon capture and storage. Moreover, if tasked with convincing different target groups to support CO2 mineralisation, stakeholders prioritise diverse themes, recognising that communication strategies must address the specific concerns of each group. Overall, the results can help investors, managers, and policymakers to ensure that upcoming decisions in R&D, investments, and the design of support mechanisms align with the priorities of key stakeholders. Our results facilitate communicating technological potentials and risks and can foster successful development and implementation of CO2 mineralisation pathways.

Beschreibung: Assessing global progress on human adaptation to climate change is an urgent priority. Although the literature on adaptation to climate change is rapidly expanding, little is known about the actual extent of implementation. We systematically screened 〉48,000 articles using machine learning methods and a global network of 126 researchers. Our synthesis of the resulting 1,682 articles presents a systematic and comprehensive global stocktake of implemented human adaptation to climate change. Documented adaptations were largely fragmented, local and incremental, with limited evidence of transformational adaptation and negligible evidence of risk reduction outcomes. We identify eight priorities for global adaptation research: assess the effectiveness of adaptation responses, enhance the understanding of limits to adaptation, enable individuals and civil society to adapt, include missing places, scholars and scholarship, understand private sector responses, improve methods for synthesizing different forms of evidence, assess the adaptation at different temperature thresholds, and improve the inclusion of timescale and the dynamics of responses.

Beschreibung: Cette étude est le fruit de la collaboration d’une équipe de recherche pluridisciplinaire composée de juristes, de sociologues et de philosophes et s’inscrit en outre dans la transversalité juridique (droit public et droit privé / droit interne et international). Réalisée sur une période de deux années et demie, elle a eu pour objectif d’identifier, dans un premier temps, les idées et les réalisations pouvant être rattachées au transhumanisme. Pour ce faire, des enquêtes de terrain ont été menées auprès d’acteurs divers et aux opinions variées situés en France, en Angleterre et en Espagne : militants transhumanistes, penseurs critiques, « personnes augmentées » (personnes ayant recours sciemment à des modifications technologiques pour « augmenter » leurs capacités physiques et/ou cognitives), professionnels de santé (de diverses spécialités) et chercheurs dans la lutte contre le vieillissement, l’intelligence artificielle et les prothèses. La synthèse de ces échanges permet de conclure, tout d’abord, qu’il n’existe pas un mais des transhumanismes et que les partisans de cette idéologie ne mettent pas tous l’accent sur les mêmes priorités. Elle met ensuite en exergue l’existence de glissements parfois imperceptibles, dans le domaine médical, vers l’augmentation technologique et/ou génétique de l’être humain. Il importe d’ores et déjà de penser le transhumanisme dans sa complexité pour en normer les conséquences ramifiées pouvant conduire à de véritables changements civilisationnels. Un droit de la condition humaine future reste à construire en conscience de responsabilité envers les générations futures. C’est ainsi que, dans un second temps, l’équipe a mis à l’épreuve certaines notions fondamentales du droit – telles que les notions de personne, de responsabilité, de propriété, de patrimoine, de droits humains et de souveraineté – à l’aune du transhumanisme. Cette recherche s’inscrit dans une dynamique résolument prospective et imaginative. Elle vise à éprouver les forces et les faiblesses de ces notions cardinales du droit et à s’interroger sur leur adaptabilité et leur perméabilité aux idées et réalisations transhumanistes.

Beschreibung: The involvement of early career researchers (ECRs) has been limited during the past Intergovernmental Panel on Climate Change (IPCC) assessment cycles. We conducted a global survey among ECRs and interviewed key experts of the IPCC process. Our results show that ECRs are highly motivated to become actively involved in the IPCC process but face a number of barriers to contribute. Mutually beneficial ways forward on how ECRs could contribute are outlined here, and recommendations to implement these paths are suggested to IPCC as well as to ECRs. Concluding, we show that ECRs have great potential to actively contribute to the IPCC process for the continuity of the IPCC as well as to climate science in general.

Beschreibung: From 7 to 18 March 2022, governments will continue negotiations on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction under the auspices of the United Nations. After a break of nearly two years due to the coronavirus pandemic, a binding UN instrument should be ready this year.

Beschreibung: The climate is already changing, making climate change adaptation (CCA) an essential component of any sustainable development strategy. Similarly, the capacities of different actors to adapt to climate change are significantly affected by social and economic factors including nutrition, health, and employment. The Sustainable Development Goals (SDGs) characterize progress toward the aforementioned factors as well as CCA through targets under SDG 13 (Climate Action). More recently, the 2019 Global Sustainable Development Report (GSDR) illustrates the interactions within and between SDGs, showing how many other SDGs influence progress toward CCA and vice versa. Businesses need to be mindful of these complex interdependencies when developing risk management, supply chain management, and sustainability strategies to make effective contributions to CCA while avoiding ineffective or maladaptive strategies. In this chapter, we demonstrate these interdependencies by modeling the interactions defined in the 2019 GSDR using the cross-impact balances (CIB) method, which identifies self-reinforcing scenarios and traces the systemic effects of interventions. We focus our analysis on how existing global business priorities may push the system toward certain scenarios over others, centering the implications for CCA. Through our analysis, we find six self-reinforcing scenarios for global SDGs, half of which indicate progress in CCA. We also identify six SDGs that appear critical to achieving all SDGs, highlighting gaps in current business efforts and areas for additional focus. Among these critical SDGs is SDG 13 (Climate Action), reaffirming the importance of CCA in progress toward sustainable development.

Beschreibung: This opinion article offers insights into the geopolitics of the ongoing global energy transition. In doing so, it draws heavily on a workshop in Berlin in late 2018, and a subsequent paper in the journal Nature. Four scenarios are presented. First, the “Big Green Deal” offers a positive story of the future, under the assumption that there will be a multilateral approach to tackling climate change. Second, “Dirty Nationalism” explores the fallout of nations choosing to turn inward and pursue a short‐term, protectionist, and self‐interested agenda. Third, “Technology Breakthrough” illustrates how a technological leap forward could lead to a great power rivalry and distinct regional energy blocs. Finally, “Muddling On” investigates the outcome of an energy transition that reflect business as usual. By comparing and contrasting the different scenarios, the article highlights the potential winners and losers of the different scenarios, and the geopolitical consequences. It also sketches the implications for policy, theory, and scenario thinking more broadly.

Beschreibung: This report was prepared as part of the STRONG High Seas project, based on a series of stakeholder surveys and experience gathered through various workshops held in the Southeast Pacific region, as well as on literature surveys and expert opinion. The report was reviewed by experts to validate findings and ensure robust content. This report is part of a series of reports covering issues of ocean governance with a focus on the ABNJ of the Southeast Pacific and the Southeast Atlantic regions and builds on previous reports published by the STRONG High Seas project. Further project reports cover the legal and institutional framework applicable to ABNJ, the ecological state and the socioeconomic importance of ABNJ in the project regions, options for management and conservation measures for conservation of marine biodiversity in ABNJ, and considerations for integrated ocean management. These reports are available through the STRONG High Seas project website. Following this introductory chapter, Chapter 2 provides relevant context with regards to ocean governance in areas beyond national jurisdiction, the ongoing negotiations towards a new agreement under UNCLOS and related capacity development needs and approaches. Chapter 3 presents a short summary of the surveys undertaken by the STRONG High Seas project with regards to capacity needs in the Southeast Pacific region and Chapter 4 is a summary of the corresponding capacity development efforts undertaken as part of the STRONG High Seas project. Chapter 5 provides reflections and recommendations for future capacity development activities beyond the scope of the project and highlights lessons learned through the five years of this project. Additional background information is provided in the Annexes.

Beschreibung: Le professeur de politique publique Andreas Goldthau et l’économiste Simone Tagliapietra expliquent, dans une tribune au « Monde », comment un club climatique ouvert pourrait contribuer à la justice climatique et aider les pays pauvres.

Beschreibung: Recently, there has been an intense debate around the concept of mobility justice, which has been developed from approaches in political theory in articulation with social struggles. In this paper, I argue that a political–economic foundation of the concept is helpful to determine the constitutive meaning of inequality within the framework of capitalist societies and, based on this, to elicit the possibilities and limits of implementing the concept in practice. The analysis focuses on the debate concerning the ongoing sustainable transformation of transportation and mobility (the Verkehrswende) in Germany. I contend that issues of justice are fundamental to such a transition and, in practice, are implicitly negotiated; nevertheless, at present, narrow interpretations of the Verkehrswende (as shaped and constrained by dominant political and economic actors) effectively marginalise considerations of mobility justice. Aspects of justice (climate justice, just transition) that are compatible with straightforward automotive electrification are taken up, whereas aspects that go beyond this, such as resource justice or questions of access to mobility, remain marginalised.

Beschreibung: Systemic risks, as opposed to conventional risks, bear the danger of destroying entire systems. Their understanding and governance remain a serious challenge. The phenomena of systemic risks show many analogies with those of dynamic structure generation in the systems of nature, technology, and society, including simple model systems of physics and chemistry. By analyzing these model systems, the elementary processes and the generic mechanisms by which they generate macroscopic dynamic structures become evident. Generalizing these insights makes it possible to formulate the basic framework of a theory of systemic risks with elements providing hints for adequate governance strategies. Although these insights cannot be applied to societal processes one by one, they reveal generic patterns and clusters.

Beschreibung: This study reports comprehensive analysis of seasonal and inter-annual variations of aerosol properties (optical, physical and chemical) and radiative effects over Pokhara Valley in the foothills of central Himalayas in Nepal utilizing the high-quality multi-year columnar aerosol data observed recently from January 2010 to December 2017. This paper focusses on the seasonal and inter-annual variations of chemical (composition), and absorption properties of aerosols and their radiative effects. The single scattering albedo (SSA) either decreases as a function of wavelength or remains independent of wavelength. The seasonal mean aerosol absorption optical depth (AAOD) exhibits a behavior opposite to that of SSA. Carbonaceous aerosols (CA) dominate (≥60%) aerosol absorption during the whole year. Black carbon (BC) alone contributes 〉60% to AAODCA while brown carbon (BrC) shares the rest. The absorbing aerosol types are determined to be BC, and mixed (BC and dust) only. Dust as absorbing aerosol type is absent over the Himalayan foothills. The ARFSFC is ≥ -50 Wm-2 except in monsoon almost every year. The ARFATM is ≥ 50 Wm-2 during winter and pre-monsoon in all the years. ARFESFC, ARFETOA and ARFEATM follow a similar pattern as that of ARF. High values of ARFE at SFC, TOA and ATM (except during monsoon when values are slightly lower) suggest that aerosols are efficient in significantly modulating the incoming solar flux throughout the year. The annual average aerosol-induced atmospheric heating rate (HR) over Pokhara is nearly 1 K day−1 every year during 8-year observation, and is highest in 2015 (∼2.5 K day−1). The HR is about 1 K day−1 or more over all the locations in IGP during the year. These quantitative results can be used as inputs in global/regional climate models to assess the climate impact of aerosols, including on regional temperature, hydrological cycle and melting of glaciers and snowfields in the region.

Beschreibung: A sustainability transition in line with achieving global climate goals requires the implementation of win-win strategies (WWS), i.e. socioeconomic activities that enable economic gains while simultaneously contributing to climate change mitigation or adaptation measures. Such strategies are discussed in a variety of scientific communities, such as sustainability science, industrial ecology and symbiosis and circular economy. However, existing analyses of win-win strategies tend to take a systems perspective, while paying less attention to the specific actors and activities, or their interconnections, which are implicated in win-win strategies. Moreover, they hardly address adaptation WWS. To address these gaps and support the identification and enhancement of WWS for entrepreneurs and policy-makers, we propose a typology of WWS based on the concept of a value-consumption chain, which typically connects several producers with at least one consumer of a good or service. A consideration of these connections allows an evaluation of economic effects in a meso-economic perspective. We distinguish 34 different types of WWS of companies, households and the state, for which 23 real-world examples are identified. Further, contrary to prevailing views on the lack of a business case for adaptation, we do identify real-world adaptation WWS, though they remain underrepresented compared with mitigation WWS. Our typology can be used as an entry point for transdisciplinary research integrating assessment of individual transformative socioeconomic activities and highly aggregated approaches assessing, e.g. the macro-economic effects of WWS.

Beschreibung: Eco-efficiency enhancement is an inherent requirement of green development and an important indicator of high-quality development in general. It aims to achieve the coordinated development of nature, the economy, and society. Therefore, eco-efficiency measurements should focus on not only total factor input, but also process analysis. Based on the “full world” model in ecological economic theory, this study constructed a theoretical framework for a composite economic-environmental-social system that reflects human welfare and sustainability. To this end, using network data envelopment analysis (DEA), this study established a staged eco-efficiency evaluation model that uses economic, environmental, and social factors to measure the overall and staged eco-efficiency of China’s provinces from 2003 to 2016 and analyze its spatiotemporal characteristics. A geographically weighted regression (GWR) model was also used to analyze the influencing factors of eco-efficiency changes and the spatial differentiation in their effect intensity. The findings were as follows: (1) China’s overall eco-efficiency is still at a low level. It varies significantly from region to region, and only three regions are at the frontier of production. The eastern region has the highest eco-efficiency, followed by the central region, and the gap between the central and western regions has gradually narrowed. In terms of staged efficiency, the level of eco-efficiency in the production stage is less than in the environmental governance stage, which is less than that in the social input stage. (2) In terms of the efficiency of each stage, the efficiency level of the production stage showed a downward trend throughout the entire process, and the decline in the central and western regions was more obvious. The social input stage and the environmental governance stage both showed upward trends. The social input stage showed a higher level, and the increase was relatively flat during the period of study. Efficiency continued to rise during the environmental governance stage from 2003 to 2010 and rose overall, but with some fluctuations from 2011 to 2016. (3) Geographically weighted regression showed that the effects of the influencing factors on eco-efficiency had obvious spatial heterogeneity. The factors affecting overall, production stage, and social input eco-efficiency were, in order of effect intensity from high to low, economic growth level, marketization level, and social input level. In terms of environmental governance, social input level had the greatest impact, followed by economic growth; marketization level did not show a significant impact.

Beschreibung: The recent decision by the German Constitutional Court in Neubauer et al. versus Germany has been attracting considerable attention around the globe. The Court ordered the German legislature to correct and to significantly tighten up existing climate law provisions, to increase the ambition of these provisions, and to strengthen future mitigation pathways. Several commentators have hailed it as an example of what is possible when the judiciary steps in to fill gaps in global climate governance as a result of governments failing to act or acting inadequately. In this article, I explore the extent to which the Court in Karlsruhe has innovatively managed to embrace a holistic planetary view of climate science, climate change impacts, planetary justice, planetary stewardship, earth system vulnerability, and global climate law, within the context of a human-dominated geological epoch, to guide its reasoning and findings. My proposal is that courts will have to increasingly follow a planetary perspective that is grounded in the Anthropocene context when adjudicating matters related to global disruptors such as climate change. This decision offers a first, and important, example of a promising new paradigm that I term planetary climate litigation.

Beschreibung: Connectivity is essential to consider in area-based marine conservation measures because it greatly impacts vital ecological processes (e.g., recycling nutrients, regulating temperature, sequestering carbon, and supporting the life cycle of species). However, it is generally not well studied or integrated into conservation measures, particularly in the Southeast Pacific. This region is home to the Salas y Gómez and Nazca ridges, two adjacent seamount chains that stretch between the Peruvian coast and Rapa Nui (i.e., Easter Island). The area has been recognized for its exceptional natural and cultural significance as well as one of the most important global areas to protect. However, over 73% of the ridges are in areas beyond national jurisdiction, where they are unprotected and under threat. This study provides a synthesis of what we know about connectivity in the Salas y Gómez and Nazca ridges and provides practical recommendations for integrating this knowledge into conservation and management measures for the region. While data on connectivity is still limited, it should not constrain the development of conservation measures, which should be co-designed and co-developed, leveraging the expertise of international working groups throughout the region. Due to their high rates of endemism, as well as importance as migratory corridors, enacting large-scale conservation measures would address important conservation considerations for both connectivity and endemism. Enacting such large-scale conservation measures would not only elevate the Salas y Gómez and Nazca ridges as an exemplary case study, providing lessons for other marine regions seeking to implement similar measures, but could also help raise awareness on the severity of externally originating threats like climate change and plastic pollution to global audiences.

Beschreibung: A recent article in this journal claimed to assess the socio-technical potential for onshore wind energy in Europe. We find the article to be severely flawed and raise concerns in five general areas. Firstly, the term socio-technical is not precisely defined, and is used by the authors to refer to a potential that others term as merely technical. Secondly, the study fails to account for over a decade of research in wind energy resource assessments. Thirdly, there are multiple issues with the use of input data and, because the study is opaque about many details, the effect of these errors cannot be reproduced. Fourthly, the method assumes a very high wind turbine capacity density of 10.73 MW/km2 across 40% of the land area in Europe with a generic 30% capacity factor. Fifthly, the authors find an implausibly high onshore wind potential, with 120% more capacity and 70% more generation than the highest results given elsewhere in the literature. Overall, we conclude that new research at higher spatial resolutions can make a valuable contribution to wind resource potential assessments. However, due to the missing literature review, the lack of transparency and the overly simplistic methodology, Enevoldsen et al. (2019) potentially mislead fellow scientists, policy makers and the general public.

Beschreibung: In spring 2020, we asked ourselves: What effects are the Corona restrictions having on projects in energy and marine research that actively include interest groups (or stakeholders) in their research?

Beschreibung: The effects of human activities are increasingly overwhelming the geologic, biological and chemical processes that drive changes in the abundance of trace and greenhouse gases (GHGs) in the atmosphere and Earth System behaviour. Thus, mankind has opened a new geological epoch or age – the Anthropocene. This development is driven by the strong population increase which may result in ten billion people by 2100. With this population increase, human demands for food and animal protein in particular, clean water, natural resources and nutrients such as fixed nitrogen (N) and phosphorus (P), land and energy will continue to increase strongly. It is also hypothesised that human enterprise is responsible for the sixth mass species extinction. Further, releases of gases such as sulphur dioxide (SO2), nitric oxide (NO) and chlorofluorocarbons (CFC) into the atmosphere are several times higher than natural emissions. CFCs give rise to highly active radicals in the stratosphere which destroy ozone (O3) by catalytic reactions. However, CFC emissions have been drastically reduced and stratospheric O3 concentrations are increasing. In contrast, concentrations of GHGs such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) continue to increase and are now well above the preindustrial levels as increasing human demand for energy is met by burning fossil fuels. As a consequence, land and ocean temperatures are increasing, glaciers are melting and sea levels are rising. Strong reductions, in particular, of the anthropogenic CO2 emissions are needed to minimise risks of future warming and its consequences as CO2 is the major GHG with part of it having a long atmospheric residence time. However, CO2 emissions continue to increase even during the periods of global economic crises and reduced industrial activities. Thus, geoengineering or climate engineering techniques are discussed to cool Earth indirectly by removing CO2 from the atmosphere or directly by increasing backscattering of solar radiation into space. For example, injecting sulphur (S) into the stratosphere has been proposed as sulphate particles reflect sunlight but many issues remain unresolved. Thus, a strong reduction in anthropogenic CO2 emissions is needed to mitigate climate change.

Beschreibung: In May 2020 I was a guest on an episode of the TV show "Planet Wissen" dedicated to "Pathways out of the Plastic Flood". It was an opportunity for me to talk about the preliminary results of our work in the ENSURE project on "Plastic: Social Perception and Behaviour Patterns". The journalist Andrea Wojtkowiak had sent me a few questions in advance, but - as is so often the case - there wasn't enough time to discuss everything in detail during the programme itself. So for all those interested in the issue of plastic, here are the more in-depth answers.

Beschreibung: The chapter defines environmental sustainability and creates a linkage between energy and the environment. It highlights the impact of both renewable energy technologies and nonrenewable energy usages on the environment. The complementarities and conflict of energy security and environmental securities are discussed along with some case studies.

Beschreibung: 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.

Beschreibung: Monitoring, control and surveillance (MCS) is critical for the success of marine conservation and management, but effective MCS remains challenging. This is especially true for the deep and distant waters of marine areas beyond national jurisdiction (ABNJ), which are characterised by a fragmented governance framework and reliance on flag States to ensure control over vessels. A range of existing international instruments, institutions and guidelines are relevant to MCS in ABNJ, while traditional approaches to MCS – on board observers, logbooks and surveillance planes – are increasingly being supplemented by a range of innovative new technological tools. States at the United Nations (UN) are currently negotiating an international legally binding instrument (ILBI) for the conservation and sustainable use of the biological diversity of marine areas beyond national jurisdiction (BBNJ) and there is a growing interest in how MCS tools and policies can contribute to the management of this vast global commons. The negotiations therefore provide an important opportunity to learn from the wealth of experience gained to date and strengthen existing provisions, thereby facilitating harmonised and efficient MCS that can ultimately ensure effective implementation of rules on the conservation and sustainable use of marine biodiversity. Against this background, this report explores how the BBNJ negotiations can strengthen MCS in ABNJ and highlights how MCS can contribute to the implementation of the new instrument. The report provides an overview of existing legal frameworks, technological tools and MCS initiatives, and highlights some of the challenges to effective MCS. The report provides some suggested pathways for strengthening MCS in ABNJ, as well as three concrete proposals for provisions that could be included in the future international instrument: 1) Reinforcing MCS flag State obligations in the text and ensuring the principles and related obligations of cooperation and coordination, transparency and reporting are applied throughout the agreement; 2) Specifying that a clearing-house mechanism will serve as a platform to share good MCS practices, exchange data on MCS activities and match capacity-building needs in relation to MCS tools and methods for assessment; and 3) Requiring States parties to submit a MCS strategy together with proposals for area based management tools (ABMTs) and marine protected areas (MPAs) that considers the possible technological tools and institutional arrangements available to ensure compliance.
