The article draws from institutional and social vulnerability theories and examines the determinants of climate risk transparency by local governments. Using data from Florida cities, the study investigates the impact of membership in climate networks and local socioeconomic and sociodemographic factors on web-based climate risk transparency. The findings support the view that membership in climate compact organizations, such as the International Council of Local Environmental Initiatives (ICLEI) and Southeast Florida Regional Climate Compact (SEFRCC), serve as institutional factors that lead to climate risk disclosures and contribute to improved adaptive governance and transparency. It also shows that college education, which likely enhances individuals’ ability to search for, interpret, and use information regarding climate risk, contributes to the decision to disclose information. Lastly, it reveals that bigger cities are more likely to disclose climate risk to mitigate these threats because disasters in large urban centers affect businesses and commuters and cause more significant damage than in smaller towns.
