AMCEs of attribute levels on public support for project development
This plot reports average effects of each project element on support for the project in an online sample of PA residents (n = 894). Point estimates are AMCEs with 95% confidence intervals (mean values ± s.e.m.) for each level. Each AMCE estimates how inclusion of the listed project feature affects support for energy projects. Each element is compared against a baseline category, represented by points without lines.
Marginal means by respondent party (experiment 1)
a–c, This plot reports differences in subgroup preferences between Democrats (blue circle, a) and Republicans (red square, b), along with the difference in marginal means between subgroups (black triangle, c) in an online sample of PA residents (n = 894). Point estimates are marginal means with 95% confidence intervals (mean values ± s.e.m.) for each level. Marginal means are centred around 50%, indicating no difference between levels.
AMCEs of attributes on local elected official support for project development
The figure reports average effects of each project element on support for the project in an online sample of local elected officials in PA (n = 206). Point estimates are AMCEs with 95% confidence intervals (mean values ± s.e.m.) for each level. Each AMCE estimates how inclusion of the listed project feature affects support for energy projects. Each element is compared against a baseline category, represented by points without lines.
Marginal means by respondent party (experiment 2)
a–c, This plot reports differences in subgroup preferences between Democrats (blue circle, a) and Republicans (red square, b), along with the difference in marginal means between subgroups (black triangle, c) in an online sample of local elected officials in PA (n = 206). Point estimates are marginal means with 95% confidence intervals (mean values ± s.e.m.) for each level. Marginal means are centred around 50%, indicating no difference between levels. In c, positive differences indicate that Republicans prefer the level.
AMCEs of attributes on predicted constituent preferences compared with actual resident preferences
a,b, Predicted constituent preferences (online sample of local elected officials in PA, n = 206) (a) compared with actual resident preferences from experiment 1 (online sample of PA residents, n = 894) (b). Point estimates are AMCEs with 95% confidence intervals (mean values ± s.e.m.) for each level. Each AMCE estimates how inclusion of the listed project feature affects support for energy projects. Each element is compared against a baseline category, represented by points without lines. Attribute levels are indicated on the outside panels, noting that levels differed slightly between experiments.

Rapidly building utility-scale energy infrastructure requires not only public support but also political will across levels of government. Here we use a conjoint experiment to assess preferences for large-scale energy projects among residents and local elected officials in Pennsylvania—a key transition state with high solar potential where siting authority rests at the local level. We find that residents prefer solar to other energy projects, and job creation and cooperative community ownership are associated with increased support. Public and elected official support decreases when projects are owned by foreign companies. We find limited partisan differences in preferences, suggesting a path towards bipartisan support for such projects. Elected officials misperceive their constituents’ preferences, underestimating support for renewable energy and the importance of job creation. As local officials are key decision-makers regarding infrastructure development, their preferences and perceptions of constituents’ preferences may dictate which energy projects are approved and what community benefits they deliver.

Rapidly building utility-scale energy infrastructure requires not only public support, but also political will across levels of government. This research explores determinants of opposition and support for large-scale energy projects among residents and local elected officials in Pennsylvania—a key transition state due its high solar potential, and where siting authority rests at the local level. This work extends prior research by using a conjoint to compare many project characteristics simultaneously, expanding the set of characteristics typically considered, sampling both the public and elected officials in a key transition state, and assessing the accuracy of public officials’ perceptions of their constituents. Using a conjoint experiment, we assess support for different characteristics of energy projects among a demographically representative sample of residents (n = 894) and a sample of local elected officials (n = 206). Key findings include that creation of permanent, union-wage jobs and cooperative community ownership increases support for energy projects and that solar projects are preferred over wind, nuclear, and natural gas power plants with carbon capture and storage. Support among both the public and local elected officials is lower when projects are owned by foreign companies. Strikingly, we find limited partisan differences in preferences for large scale renewable energy project characteristics, suggesting a promising path towards building bipartisan support for such projects. We also find, however, that local elected officials misperceive the preferences of their constituents, underestimating support for renewable energy and the importance of job creation. Given the role of local elected officials as key decision-makers regarding energy infrastructure development, their preferences and how they perceive their constituents’ preferences may dictate what types of energy projects are approved and what benefits they deliver to local communities.

While cities in the United States play an active role developing and implementing climate policy, urban centers are often sites of socio-spatial inequity. Thus, we explore how cities grapple with these inequities in their Climate Action Plans (CAPs). While CAPs can empower cities to engage in equitable planning practices that prioritize marginalized communities, little empirical research examines how equity goals are measured and evaluated. We find that among large U.S. cities with CAPs, less than one third include measurable indicators to evaluate progress towards achieving equity goals. Across climate adaptation and mitigation planning, nineteen cities consider equity goals as they relate to ten thematic areas, six outcomes, and five dimensions of equity. We suggest ways forward for cities to develop, implement, and measure a diverse and holistic set of equity indicators to use in their climate planning efforts and beyond.

Addressing many social challenges requires both structural and behavioral change. The binary of an i- and s-frame obscures how behavioral science can help foster bottom-up collective action. Adopting a community-frame perspective moves toward a more integrative view of how social change emerges, and how it might be promoted by policymakers and publics in service of addressing challenges like climate change.

... Secondly, there is substantial evidence that the American public overall underestimates other's climate concern 52-54 . Finally, recent work with a localized group of policymakers, found that policymakers meaningfully underestimated constituent support for sustainable energy projects 55 . Interestingly, in Trial One, the actual percentage of citizens worried about climate change in a state did predict greater message engagement, suggesting that policymakers share similar levels of concern about climate change to their constituents. ...

... While the case for engagement is increasingly acknowledged in existing carbon removal fora (Carbon180, 2021;XPRIZE Carbon Removal, 2023), in practice engagement is often undertaken as a means to defuse public resistance (Department of Energy Office of Clean Energy Demonstrations, 2023), rather than to involve communities in strategic decision-making. Proactive engagement is needed on both strategic sectoral and specific project-related decisions (Nawaz et al., 2024). Private developers should undertake extensive and meaningful engagement with all groups potentially affected by carbon removal projects. ...

... Governance was a key aspect of many infrastructure system boundaries, constituting a route to wellbeing (by contributing to decision making (Velasco-Herrejón et al 2024)), and a moderator of goals and visions through spending decisions (Lashof and Neuberger 2023) and competence/preparedness (Creutzig et al 2022). Social practices were included in the boundary of analysis for several papers, recognised as creating obduracy and holding current infrastructure in place (Creutzig et al 2022), as a key point of interaction between physical infrastructure assets with skills and meaning highlighting the relational nature of infrastructure (Ahamed et al 2023) and as a determinant of infrastructure use (Kalonde et al 2023). Social aspects, such as organisation of work and 'social infrastructure' such as education, and healthcare were included in several papers (Ahamed et al 2023, Lashof andNeuberger 2023) and actors such as emergency responders were included in infrastructure systems in Yuan et al (2022). ...

... Interestingly, larger households demonstrated greater awareness of specific environmental contaminants (PBDEs and PFAS), potentially linked to increased social interactions within the family unit. This observation supports the Social Learning Theory, which suggests that family members can learn about environmental issues through observation and discussion with each other, highlighting the role of social dynamics in shaping environmental awareness (Ardoin et al., 2023;Caggiano et al., 2023). ...
