Excess Urban Heat Mitigation Act of 2025

The Excess Urban Heat Mitigation Act of 2025 creates a federal grant program to fund heat-reduction projects in communities most affected by urban heat islands, primarily low-income neighborhoods (defined as census tracts with ≥20% poverty rate) and areas with higher heat exposure for communities of color. It authorizes $30 million annually for grants to states, cities, tribes, or nonprofits for projects like planting native trees, installing cool roofs/pavements, building shaded transit stops, and creating community cooling centers. Grants require community engagement plans to ensure equitable participation and prioritize projects in underserved areas (75% of funds must target "covered census tracts"). The program mandates annual reporting to Congress and includes oversight to evaluate project success in reducing heat impacts.
