Health impact assessment (HIA) is a tool that can be used to examine the potential health impacts of proposed climate change policies and offer recommendations to promote health and mitigate adverse health consequences of such policies. We used an HIA database, a literature search, and expert consultation to identify 12 HIAs of the proposed climate change policies from six states in the U.S. These policies included cap-and-trade legislation, heat-wave and sea-level-rise mitigation and adaptation, transportation policy impacts of climate change, carbon-reduction strategy scenarios, soil- and water-conservation strategies, urban forest canopy for climate adaptation, overheating buildings, and regional transportation plan and sustainable communities strategies. In four descriptive summaries, we found that HIAs foster stakeholder engagement and provide useful health-promoting recommendations. HIAs can facilitate cross-sector collaboration, help optimize the health co-benefits of climate change policies, and raise awareness among decision makers of health impacts of those proposed policies.
