Climate Health Emergency Act of 2025

This bill mandates the Secretary of Health and Human Services to declare a public health emergency under section 319 of the Public Health Service Act, specifically for health risks associated with climate change . Congressional findings assert that climate change is driving or exacerbating extreme weather events and infectious diseases, linking it to over half of recent public health emergency declarations. The legislation highlights that climate change is identified as the most significant health threat of the 21st century, yet the U.S. public health infrastructure remains unprepared. To address this, the bill emphasizes the need to mobilize Federal resources, enable data sharing, and coordinate across agencies. The overarching purpose is to build a public health system resilient to the intensifying threat of climate change, thereby protecting communities and vulnerable individuals.
