Background: The decarbonization of the mobility sector is one of the main challenges in the context of climate mitigation. In Germany, as in many other countries, policy measures aiming to make the mobility system greener frequently fail to produce substantial results, not least due to a lack of support by large sections of the general public. Policy measures directed at reducing car traffic in particular are often met with indifference and resistance. The question thus arises: what basis do citizens use to form their (often negative) opinions about sustainable mobility policies? As a conceptual starting point for our empirical analysis, we draw on the frame concept and focus on people's frames of the politics of mobility. With "politics of mobility" we refer to everything people could consider as political with regard to mobility. We understand frames as culturally mediated patterns of interpretation that ultimately motivate and guide actions. Results: Based on interviews and focus group data gathered in the region of the city of Stuttgart (Germany), we identify two dominant frames as well as combinations of these frames by which people make sense of the activities of political actors in the field of mobility. In one frame, which we labeled "politics-as-actor", mobility politics are interpreted with reference to politics as some kind of monolithic abstract actor. In the other, which we labeled as "politics-as-staged-process", mobility politics are portrayed as an interest-driven, opaque process that only purport to being democratic. Conclusions: In terms of policy recommendations, we use our findings to derive suggestions for how to increase support for green mobility policies: transparent implementation of policy measures, pragmatic policy styles and the involvement of intermediaries.

Biodiversity loss and climate change are deeply intertwined and constitute a complex and interdependent crisis. These interlinked sustainability issues need to be addressed through an integrated approach. However, governments have been slow to integrate the need to protect both climate and biodiversity into environmental governance. NGOs, as non-profit organisations promoting public good, are seen as having the potential to recognise and advocate for this much-needed holistic protection of climate and biodiversity. But to what extent and in what ways do NGOs recognise this climate-biodiversity nexus? This article addresses these questions through an analysis of 107 German climate NGOs, examining their 190 annual reports from two time periods, 2016/2017 and 2021/2022. We found that, while German climate NGOs have made significant progress in recognising the climate-biodiversity nexus, they lack recognition of the role of biodiversity in stabilising the climate and the unintended negative consequences of climate policies and measures for biodiversity, highlighting that NGOs are still far from being holistic environmental stewards. Climate NGOs need to integrate the interplay between climate and biodiversity objectives into their organisational activities and align their mandates to promote synergies and minimise trade-offs between climate and biodiversity actions. We suggest that one way forward is to increase collaboration between NGOs. NGOs could then complement each other's expertise and be better placed to jointly contribute to finding integrated solutions for climate and biodiversity protection and mainstreaming biodiversity into climate policy.

Prior evidence suggests that perspective-taking may promote pro-environmental behavior, at least for low-cost behaviors or local environmental problems. Climate change, however, requires costly mitigation efforts and is a global problem. Thus, in this study, we examine whether perspective-taking in the context of climate change is effective in promoting mitigation behaviors, including actual and/or costly behaviors, the mechanisms through which perspective-taking works, and if the distance to the person adversely affected by climate change matters for the effect. We conducted an online experiment with a non-student sample from Germany (n = 557), utilizing a 2 × 2 factorial design, to investigate the impact of perspective-taking and distance on three outcome measures: a climate donation, signing a petition, and approval of mitigation policies. We find that perspectivetaking does not promote these mitigation behaviors, yet it raises the degree perspective-takers value and - for close others - feel connected with the affected person. Exploratory analysis shows that dispositional perspective-taking and empathic concern are correlated with mitigation behaviors. [ABSTRACT FROM AUTHOR]

Adverse consequences of climate change often affect people and places far away from those that have the greatest capacity for mitigation. Several correlational and some experimental studies suggest that the willingness to take mitigation actions may diminish with increasing distance. However, the empirical findings are ambiguous. In order to investigate if and how socio-spatial distance to climate change effects plays a role for the willingness to engage in mitigation actions, we conducted an online experiment with a German population sample (n = 383). We find that the willingness to sign a petition for climate protection was significantly reduced when a person in India with a name of Indian origin was affected by flooding, as compared to a person in Germany with a name of German origin. Distance did not affect donating money to climate protection or approving of mitigation policies. Our results provide evidence for the existence of a negative effect of distance to climate change consequences on the willingness to engage in low-cost mitigation actions. Investigating explanations for such an effect, we find that it can be attributed to the spatial rather than the social dimension of distance. Moreover, we find some cautious evidence that people with strong racist attitudes react differently to the distance manipulations, suggesting a form of environmental racism that could also reduce mitigation action in the case of climate change.

Environmental catastrophes, including the increased severity and frequency of climate extremes, can act as "windows of opportunities" that challenge citizens' mental models and motivate them to engage in reflective processes, challenging their pre-conceived ideas. Less well understood is whether experiencing changing weather conditions, common in mid-latitudes, can have a similar effect and increase the citizens' concerns about climate change and their willingness to accept more stringent climate policies. In this paper, we investigate the effects of changing seasonal temperature on the perceived seriousness of climate change and willingness to mitigate climate change. We use data from four yearly waves of a spatially explicit representative population survey in Germany and weather records from the postal code areas in which they live. To our knowledge, this study is the first analysis to link individual perceptions towards climate change and different mitigation options with seasonal temperature changes at specific locations in Europe. The analyzed perceptions were strongly influenced by socio-demographic characteristics and broader societal changes, as well as individual experiences of seasonal temperatures. The results show that experienced seasonal temperature change influences personal climate change concerns as well as the willingness to mitigate climate change, although with a weaker effect. The results indicate that it is the absolute temperature variation experienced that is important, rather than whether it is getting colder or warmer than usual. Considering the influences identified in this study can offer a window of opportunity for more stringent and targeted climate change policy. • Seasonal temperature changes influence climate change perception. • Effects can offer a window of opportunity for more stringent climate change policy. • Governmental mitigation policy solutions less supported than self-determined options. • Perceptions influenced by broader societal changes as well as individual experiences. • Need for targeted climate change communication.

Even throughout a global pandemic, climate change continues to be a fiercely discussed topic—both politically and legally—the world over. Particularly in light of the many Covid-19 related financial aid programs (including transnational ones) and the associated economic stabilization and reconstruction plans, a sustainable climate policy and legal order should be expected to play a role for an economy that has fallen into a slump. Nevertheless, a lively discussion on how best to achieve climate protection continues to take place in already established systems such as the private law system. Here, as far as climate change is concerned, tort law appears to be the focus of these discussions. The extent to which tort law and the issue of climate change can be brought together is also increasingly being discussed in Germany. This article attempts to shed light on the questions of how tort law could contribute to the mitigation of climate change and how climate change could fit into the law of torts of the German civil law legal system.

Strong public support is a prerequisite for ambitious and thus costly climate change mitigation policy, and strong public concern over climate change is a prerequisite for policy support. Why, then, do most public opinion surveys indicate rather high levels of concern and rather strong policy support, while de facto mitigation efforts in most countries remain far from ambitious? One possibility is that survey measures for public concern fail to fully reveal the true attitudes of citizens due to social desirability bias. In this paper, we implemented list-experiments in representative surveys in Germany and the United States (N = 3620 and 3640 respectively) to assess such potential bias. We find evidence that people systematically misreport, that is, understate their disbelief in human caused climate change. This misreporting is particularly strong amongst politically relevant subgroups. Individuals in the top 20% of the income distribution in the United States and supporters of conservative parties in Germany exhibit significantly higher climate change skepticism according to the list experiment, relative to conventional measures. While this does not definitively mean that climate skepticism is a widespread phenomenon in these countries, it does suggest that future research should reconsider how climate change concern is measured, and what subgroups of the population are more susceptible to misreporting and why. Our findings imply that public support for ambitious climate policy may be weaker than existing survey research suggests. [ABSTRACT FROM AUTHOR]

Many studies have analysed the environmental impact of vegan, vegetarian, or reduced meat diets. To date, literature has not evaluated how diet shifts affect environmental impacts by utilising portfolios which reflect personal nutrition preferences. Further, changing diets could alter the available land for non-food uses. This paper defines novel diet portfolios to outline alternative diet transitions and choices within the population and finds their effect on greenhouse gas (GHG) emissions, primary energy use, and land use in Germany. The aim of this study is to capture how these diet shifts affect land availability and increase the options for land-based climate change mitigation strategies. To do so, a contextualisation is made to compare the use of freed-up land for afforestation or biomethane production (with and without carbon capture and storage). The investigated diet portfolios lead to a reduction of the investigated impacts (GHG emissions: 7–67%; energy use: 5–46%; land use: 6–64%). Additionally, afforestation of freed-up land from each diet portfolio leads to further emission removals of 4–37%. In comparison, using the land to produce energy crops for biomethane production could lead to 2–23% further CO2-eq emission reductions when replacing fossil methane. If biomethane production is paired with carbon capture and storage, emission abatement is increased to 3–34%. This research indicates various short-term pathways to reduce GHG emissions with portfolio diet shifts. Utilising freed-up land for climate change mitigation strategies could prove essential to meet climate targets, but trade-offs with, e.g. biodiversity and ecosystem services exist and should be considered. • Diet portfolios are used to represent realistic population diets. • Diet portfolios include a mixture of 12 different diets. • GHG emissions decrease by 67% if the population adopts a Vegan diet. • Afforestation removes almost double the emissions compared to biomethane. • BECCS has similar GHG abatement to afforestation.

Is heat becoming a major threat to cities? Following the heat wave in Europe in 2003, which is estimated to have caused the deaths of 70,000 people, municipal authorities began to develop adaptation and mitigation plans and programs. Legal obligations to consider climate change within various development projects have been defined, e.g. by the latest amendment of the EU EIA (Environmental Impact Assessment) Directive (2014/52/EU) and the Federal Building Code (BauGB §1a (5)). However, urban heat hazards have not yet received as much attention as, for example, carbon dioxide emissions as drivers of global warming. Dense urban structures, high buildings, dark surfaces, and high population densities trigger urban heat effects. With about 3/4 of Europeans living in cities, measures to reduce heat-related impacts are needed. This paper evaluates how German cities have implemented measures towards climate change adaptation. The results show that 24 out of 30 cities have developed mitigation and/or adaptation plans, with a majority focusing on mitigating 2, indicating less awareness of urban heat hazards. Moreover, we found elaborate and comprehensive examples which might serve as blue-prints for adaptation strategies. Based on the inhomogeneous scope of the different plans and programs, there remains a need for guidance and more knowledge exchange among the cities on mitigation/adaptation options and preferably information on their effectiveness, to further assist cities in tackling heat stress.

There are numerous studies assessing the influence of individual sociological, political, and demographic factors on attitudes towards climate change. However, there is still a need for a deeper understanding of the reasons behind these attitudes and for research based on results from more than one country. This study empirically examines a range of psychosocial and demographic determinants of support for climate policy (renewable energy, energy efficiency and carbon tax) in Germany and Poland (n = 1969). The results show that the societies of both countries, despite significant differences in income, culture and political stance on climate change, similarly support implementation of climate policies. For both countries valid predictors of support are: awareness, emotional response to climate crisis, sense of control, and belief in effectiveness of solutions; the study also shows predictors relevant in only one country. Factor analysis identified similar dimensions of attitudes toward climate change in both countries. The main findings show that support for climate policy is high in both countries and that the public is ready to accept more ambitious climate goals. Despite the differences between the countries, a coherent climate policy seems justified. The study also shows differences between the countries and provides recommendations for policymakers.

This study investigates the different stakeholder based discourses and challenges around the Franconian Lake District (FLD), a recently constructed large reservoir system in Germany. The construction and operation of reservoirs represent a massive alteration of their natural and social environments leading to discourses and potential conflicts between a wide scope of heterogeneous interest patterns. Studies have shown that large reservoirs can be an important contributor to water supply, irrigation, energy storage and therefore climate change mitigation on a global scale, which brings these conflicting interests to a broader societal concern. Yet, information about conflicts around existing (German) reservoirs is limited. To assess which issues and conflicts appear on the daily agenda and how they are perceived, communicated and addressed by the stakeholders, a total of 609 articles in the Nürnberger Nachrichten and 22 semi-structured expert interviews were analysed, using qualitative content analysis. The results show that discourses at FLD are predominantly determined by economic factors. Management issues are dominated by discussions about cyanobacteria, which can pose a health risk, thereby impeding recreational use of the lakes and consequently causing economic losses and an image problem for the region. The issue is also strongly interlinked with other aspects of concern and therefore one of the main challenges at the FLD. Due to the construction of the lakes and the evolving strong tourism sector, the formerly agricultural region was subject to a major structural change linking together a very heterogeneous set of interests. The results of this study can help in establishing a management framework to suit all stakeholders and possibly be transferrable to similar projects. [ABSTRACT FROM AUTHOR]

Climate change is supposed to exacerbate conflicts arising from resource scarcity and contrasting objectives. Some European authors highlighted already the need to look at conflicting interests when elaborating and applying adaptation and mitigation strategies. This study analysed the level of consideration of these emerging topics arising through increased competition of resources, contrasting interests, climate change adaptation as well as mitigation measures for Austria and Southern Germany in detail. Furthermore, it surveyed the application of possible approaches for conflict prevention and mitigation in an international perspective and additionally examined the particular role of SEA as one of the instruments to cope with conflicts related to climate change. The results express the strong need to look at emerging conflicts in cross-sectoral and sectoral adaptation early enough and a strategic perspective. Based on the content analysis of the Austrian and German adaptation and mitigation documents, expert interviews as well as the international literature review, a rather low consideration of these emerging topics as well as approaches to cope with them became evident. In response to these deficiencies, the paper introduces a first framework to identify and tackle emerging and exacerbated conflicts related to climate change. This novel framework is internationally applicable. In the final step of the framework approaches to prevent and minimize conflicts are the key topic. Among these approaches, SEA could take a leading role in case mandatory planning instruments cover the topics related to potential or existing exacerbated fields of conflicts. Overall a mix of formal and informal instruments and a more cross-sectoral perspective seems necessary. To this aim, the paper introduces four main guiding principles to consider and minimize up-coming conflicting topics. • Consideration of cc related conflicts is very diverse in adaptation documents. • A more strategic view of emerging conflicts is of particular importance. • This paper presents a novel framework to identify and tackle conflicts. • SEA can partly address these conflicting topics depending on its role.

Invoking health benefits to promote climate-friendly household behavior has three unique advantages: (i) health co-benefits accrue directly to the acting individual, they are "private goods" rather than public ones; (ii) the evidence base for, and magnitude of health co-benefits is well-established; and (iii) the idea of a healthy life-style is well-engrained in public discourse, much more so than that of a climate-friendly life-style. In previous research, assessing the influence of information on health effects on people's motivation to adopt mitigation actions, health co-benefits for the individual were typically confounded with collective health co-benefits, for example from pollution reduction. The present research aims to overcome this limitation by providing information on individual health co-benefits that are unconditional on the actions of others (direct health co-benefits). We report effects of this kind of health information on stated willingness to adopt mitigation actions as well as on simulation-based carbon emission reductions in a pre-registered experimental setting among 308 households in 4 mid-size case-study cities in 4 European high-income countries: France, Germany, Norway and Sweden. For each mitigation action from the sectors food, housing, and mobility, half of the sample received the amount of CO 2 equivalents (CO 2 -eq) saved and the financial costs or savings the respective action generated. The other half additionally received information on direct health co-benefits, where applicable. For households receiving information on direct health co-benefits, we find a higher mean willingness to adopt food and housing actions, and a greater proportion very willing to adopt one or more mitigation actions (OR 1.86, 95% CI 1.1, 3.12); and a greater simulated reduction in overall carbon footprint: difference in percent reduction -2.70%, (95% CI -5.34, -0.04) overall and -4.45%, (95% CI -8.26, -0.64) for food. Our study is the first to show that providing information on strictly unconditional, individual health co-benefits can motivate households in high-income countries to adopt mitigation actions.
