This study tackles the relationship between two of the 21st century’s major challenges: climate change and democratic backsliding. Building on the extant research on right-wing authoritarian environmental politics, we explore how concerns about climate change and individual levels of trust in others and in political institutions affect support for four measures of ecofascism. By examining the association between concerns about climate change particularly among individuals with low social and political trust, this study will add to the body of knowledge and research on democratic backsliding, the political effects of the climate crisis, and explore the overall support for ecofascist tenets within the US. Using a large, non-probability sample of Americans (N=1,407) and regression analyses, we examine three factors that we hypothesize are likely to be associated with support for ecofascist ideology: climate change concern, political trust, and generalized social trust. In the first survey to examine support for ecofascism in the general population, we find that high levels of generalized social trust were associated with lower levels of support for all four ecofascism measures, but the effects of climate concern and political trust yielded mixed results.
