Although the determinants of trust in governments have received significant attention in the literature on political trust, there has been no attention paid to whether environmental concerns affect governmental trust. Yet, if individuals are worried about local and global environmental degradation, they may think that the government has failed in providing them with the best living conditions. Hence, it is plausible to expect local and global environmental concerns and trust in government to be inversely correlated. Using 2005 data from 24 countries, this hypothesis is tested against competing theories of civic participation, interpersonal trust, and economic considerations to explain individual trust in government. Multilevel models that specify the impact of individual- and national-level factors provide evidence that global environmental concerns do actually matter.
