Extreme Heat Economic Study Act of 2025

This bill directs the National Oceanic and Atmospheric Administration (NOAA) to conduct a study on the financial costs of extreme heat events. The study will quantify economic impacts including health costs (emergency care, hospitalizations), property damage, insurance claims, labor productivity losses, infrastructure disruptions, energy expenses, and agricultural losses. NOAA must coordinate with multiple federal agencies (like Health, Agriculture, and Energy Departments) and publish findings on HEAT.gov within 4 years. The bill does not create new regulations or directly affect citizens; it solely authorizes a data-gathering study to inform future policy.
