Risk perception influences the perceived salience of various policy issues. In this study, we examine the pathways through which environmental identity influences the perceived salience of two kinds of policy issues—climate change (climate mitigation and climate adaptation) and development (economic growth and infrastructure). Based on a dataset of 503 respondents from coastal communities along the east coast of the United States, our findings indicate that environmental identity is associated with a greater perceived salience of climate mitigation, and that this relationship is mediated by hydrometeorological disaster risk perception. While we found no significant total effect of environmental identity on the perceived salience of climate adaptation, perceived salience of infrastructure development, and perceived salience of economic growth, hydrometeorological disaster risk perception was found to fully mediate all three relationships. Also, the mediated relationships were found to be significantly moderated by gender identity, but not by age (except for the perceived salience of infrastructure development). The study highlights the pivotal role of hydrometeorological risk perception in modifying the perceived importance of different policy issues among environmentalists and has implications for policy and planning in coastal regions.
