The Excess Urban Heat Mitigation Act of 2025 is designed to tackle the escalating issue of extreme heat in urban areas, particularly focusing on the health risks it poses to underserved communities. The legislation establishes a grant program aimed at funding projects that mitigate urban heat and improve the quality of life for affected populations. Managed by the Secretary of Housing and Urban Development, the grant program will provide financial resources to eligible entities, including state and local governments and nonprofit organizations.
