Abstract Assessing the sustainability of energy systems must include attention to the local social and environmental impacts of such energy production, though these do not always easily align with more regional and global concerns. Social science research demonstrates that public perceptions of the social and environmental risks associated with unconventional oil and gas development (glossed by critics as “fracking”) vary both at an individual and community level. This article provides a comparative analysis of three proposed factors that influence risk perceptions: trust in government institutions, socioeconomic profile, and historical experiences with industry. We compare two Colorado communities that each had established a participatory local governance framework to minimize negative environmental impacts from oil and gas developments, but that were characterized by distinct socioeconomic profiles and industrial histories. Our quantitative analysis of citizen comments during public hearings suggests two key findings that were not predicted by the existing literature: neither trust in local government nor historical ties to heavy industry were associated with diminished risk perceptions. These findings suggest new pathways for more constructive engagement among industry, state and local government, and citizens.
