The Excess Urban Heat Mitigation Act of 2025 is designed to tackle the escalating issue of extreme heat in urban areas, particularly its adverse effects on public health and the environment. Recognizing that urban settings often suffer from elevated temperatures due to dense construction and insufficient green spaces, the Act aims to establish a grant program that empowers communities to implement projects aimed at mitigating urban heat. Central to the Act is the creation of a grant program overseen by the Secretary of Housing and Urban Development.
