With the aim of mobilizing engineers and scientists to address environmental, climate, and energy justice challenges in the United States, this study examines how engineers and scientists view their incentives, barriers, and potential for community-based collaborations. Through a purposive convenience sample (n = 281) and an online questionnaire, we investigate the attitudes and experiences of engineers and scientists regarding their community-based work. Our analyses reveal dynamics of race, class, and experience, suggesting a type of socio-demographic conditioning informing community-based collaborations. Engineers and scientists also identify four main barriers to community-based work: lack of time, lack of funding, lack of rapport, and knowledge deficits. In response, we introduce a field of collaboration with its own set of capitals-economic, cultural, social, and symbolic-and offer recommendations on how engineers, scientists, and community groups might collaborate with each other to address longstanding issues of energy, climate, and environmental injustice in the United States. Community Engineering Corps, which leverages a network of more than 200,000 professional engineers, to address water, energy, civil, and structural engineering challenges for communities that generally cannot afford professional engineering services (CEC [Community Engineering Corps], 2019). Through this study, we desire to contribute to an increased involvement of engineers and scientists with community-based work, and thus, we explore how technical experts can be better supported in addressing environmental, climate, and energy justice issues. One can imagine analogies to the field of public interest law, which has fundamentally transformed legal practice (Cummings, 2007; Freedman Consulting, 2016).
