Energy efficiency is essential for climate change mitigation. Energy management, shaped by both technical artefacts and social constructions, can overcome barriers and achieve greater emission reductions than technology-focused approaches alone. Nine social constructions of energy management emphasize the need for a broader view that includes operations, processes, and knowledge creation and diffusion. By adopting these strategies, corporations and policymakers can substantially reduce industrial energy use and emissions. We estimate that effective energy management policies and voluntary initiatives could cut at least 5% of global industrial fossil CO₂ emissions.

This study aims to expand the understanding of public acceptance of carbon taxes by exploring the role of habits. Habits play a pivotal role in guiding our behaviors and reasoning and can even influence our self perception and identity but remain an underexplored variable in relation to public policy acceptance. We employed a large scale (N > 5200) national survey to measure public acceptance of higher carbon taxation in Sweden, also capturing car driving habits, car usage, and other relevant variables. The findings show that habit strength is negatively correlated with policy acceptance, regardless of self reported driving distance, while also appearing to moderate the relationship between policy acceptance and environmental concern and political leaning, variables previously shown to be of relevance. The study suggests that the influence of habits needs to be recognized to better understand the formation of climate policy acceptance, and exploring this perspective paves the way for future research.

Using Sweden as a study case, this article explores the polarized opinions to wind and nuclear energy, two low carbon energy options that have been shown to be politically controversial. In a wide-scale survey (N = 5200), general attitudes to wind and nuclear energy are captured, as well as to projects in the proximity of people's homes. The study demonstrates a deep polarization of energy preferences in Sweden, finding strong associations between worldviews, political orientation, environmental concern, and support for or resistance to wind and nuclear energy. The study concludes that support for both energy options is reduced when wind or nuclear power is constructed near people's home, but also suggests that the proximity effect is particularly strong for individuals with strong TAN (traditional, authoritarian, nationalistic) values and right leaning political ideology. The article argues that politically motivated reasoning might explain the polarization of attitudes, yet this effect seems to become less relevant when people are asked to judge potential energy infrastructure located close them.

Two key goals for sustainable spatial planning are to promote low-carbon travel in daily life and to enhance human wellbeing through diverse human-environment interactions. Yet, the integration of these goals has been underexplored. This study investigates the potential for experiential diversity via active travel in different residential contexts within the Gävle city-region, Sweden. Over 15 months, we collected spatiotemporal data from 165 participants, analyzing 4,362 reported experiences and 13,192 GPS-derived travel trajectories. Our analysis uncovered a significant spatial discrepancy: while the travelled distances to locations of positive experiences typically ranged from 1.5 km to 5 km, active travel predominated only within 1.5 km. This discrepancy persisted across urban, suburban, and peripheral contexts. Although residents in different contexts reported the same types of experiences, urban dwellers travelled about 50 % farther for nature experiences compared with other positive experiences, whereas peripheral dwellers travelled twice the distance for urbanicity experiences compared with other positive experiences. Consequently, urban residents mostly relied on active travel for urbanicity experiences and motorised travel for nature experiences, with the reverse trend observed among peripheral dwellers. These results illustrate the importance of spatial scale for promoting diverse positive experiences via active travel, regardless of residential context. Effective planning strategies may include enhancing environmental diversity near homes and developing infrastructure that favours active over motorised travel for short to moderate distances.

The concept of social sustainability has long been a subject of discussion within academic literature and practitioners. However, there remains a lack of clarity in its definition and scholars argue that this can impacting the legitimacy of addressing social sustainability challenges. Through a systematic literature review and a content analysis, we shed light on the multifaceted discourse surrounding the concept of social sustainability, elucidating its diverse applications and meanings portrayed and defined within scholarly discourse. Our findings show that the concept predominantly revolves around four prevalent categories: Equity, Well-being, Participation and Influence, and 'Social Capital. Based on results, we develop and present a novel analytical framework of the four pillars of social sustainability, referred to as the SoSuCompass, representing a conceptual framework to clarify the concept's multifaceted nature. The framework can serve as a tool for a fuller comprehension of the definition of social sustainability.

This paper explores wind power attitudes in Sweden, considering the proximity of wind power installations, using a large-scale survey (N = 5280). The study examines if attitudes were affected by policies that provide collective financial benefits through municipal tax revenues, personal benefits through direct compensation, or openings for democratic involvement. Only 15 % of the respondents expressed negative attitudes to wind power as a measure to speed up the transition to a fossil free society, while 26 % were negative to wind power built within 5 km from their homes. Attitudes were mainly predicted by ideological standpoints, environmental concern and political and governmental trust. The study found that for wind power constructed in the home municipality, respondents preferred collectively distributed financial benefits, while direct personal compensation offers the best prospects to influence ideologically motivated attitudes. None of the policy interventions tested in this study had any significant effect on respondents with strongly negative views.

Carbon taxes are considered to be an efficient method to reduce greenhouse gas emissions; however, such taxes are generally unpopular, partly because they are seen as unfair. To explore if public acceptance of a stricter carbon tax in Sweden can be enhanced, this study investigates the effectiveness of three different policy designs, addressing collective and personal distributional consequences and promoting procedural aspects (democratic influence). A large-scale (n = 5200) survey is applied, combining a traditional multi-category answer format with a binary choice format. The results show that support for higher carbon taxation can be enhanced if tax revenues are redistributed to affected groups. Policies with collective justice framings can change the attitudes of individuals who express antagonistic attitudes to increased carbon taxation and influence groups comparably more affected by carbon taxes, such as rural residents, low-income groups, and people who are driving long distances. Policy designs addressing collective distributional consequences are, however, less effective on individuals expressing right-leaning ideological views and low environmental concern. Policies addressing personal distributional outcomes, or perceptions of procedural injustice, had no significant effect on policy acceptance.

The climate crisis demands an energy transition away from fossil fuels, and for the transport sector, this implies finding more electric or hydrogen-fuelled solutions. An emerging disruptive solution with high potential for improved sustainability is using drones as a mode of transport, i.e., Advanced Air Mobility for passenger and freight transport in urban and rural areas,fuelled by electricity or green hydrogen. As drones are being rapidly commercialized, there is a need for a policy framework for local and regional actors to address this in decision-making. This paper aims to develop a policy framework through a systematic literature review where findings have been validated by experts from industry and appropriate governance bodies. The results reveal three conceptual elements in the Advanced Air Mobility system where policy actions are needed: 1) primary tech-nology, including vehicle-related aspects; 2) functionality, including infrastructure and operations; and 3) adoption, including the environment, market, and society. The overall lack of a multi-level governance model for Advanced Air Mobility and the scarcity of knowledge of the topic within vital fields such as energy systems and regional planning are also addressed. The findings are discussed in light of regulatory frameworks for drone transportation in Europe. The paper concludes with a policy development framework for regional Advanced Air Mobility deployment and provides policy implications.

Nature-based solutions (NBS) are essential for carbon-neutral cities, yet how to effectively allocate them remains a question. Carbon neutrality requires city-led climate action plans that incorporate both indirect and direct contributions of NBS. Here we assessed the carbon emissions mitigation potential of NBS in European cities, focusing particularly on commonly overlooked indirect pathways, for example, human behavioural interventions and resource savings. Assuming maximum theoretical implementation, NBS in the residential, transport and industrial sectors could reduce urban carbon emissions by up to 25%. Spatially prioritizing different types of NBS in 54 major European Union cities could reduce anthropogenic carbon emissions by on average 17.4%. Coupling NBS with other existing measures in Representative Concentration Pathway scenarios could reduce total carbon emissions by 57.3% in 2030, with both indirect pathways and sequestration. Our results indicate that carbon neutrality will be near for some pioneering cities by 2030, while three can achieve it completely. Effective spatial allocation of the nature-based solutions is important for city mitigation through various pathways. This Analysis allocates prioritized urban nature-based solutions to major European cities and estimates their potential contribution to emission reductions, then the carbon neutrality targets.

Urban areas are associated with higher depression risks than rural areas. However, less is known about how different types of urban environments relate to depression risk. Here, we use satellite imagery and machine learning to quantify three-dimensional (3D) urban form (i.e., building density and height) over time. Combining satellite-derived urban form data and individual-level residential addresses, health, and socioeconomic registers, we conduct a case-control study (n = 75,650 cases and 756,500 controls) to examine the association between 3D urban form and depression in the Danish population. We find that living in dense inner-city areas did not carry the highest depression risks. Rather, after adjusting for socioeconomic factors, the highest risk was among sprawling suburbs, and the lowest was among multistory buildings with open space in the vicinity. The finding suggests that spatial land-use planning should prioritize securing access to open space in densely built areas to mitigate depression risks.
