Extreme Heat Economic Study Act of 2025

This bill orders a national study to count the real-dollar costs of extreme heat on people, businesses, farms, and public services. The study would add up medical bills, lost work time, higher energy bills for cooling, damage to roads and power systems, and losses to crops and livestock. It would also try to put a dollar value on lives lost and health problems caused by heat. The results must be shared with the public on HEAT.gov and in an open journal. The study can use outside experts and must rely on existing data where possible. Congress would provide $3.5 million for this work .

To do this well, the team has to gather input from many federal agencies, state and local partners, and others. The report must also suggest how to build a national system to track heat-related health costs, improve how heat deaths are counted, and measure lost productivity. The final report is due within four years of the law taking effect .

• Who is affected: patients and hospitals; workers and employers; households paying higher cooling bills; farmers and ranchers; businesses facing outages; and communities with stressed roads, energy, and water systems .
• What changes: a full, public cost picture of extreme heat, with recommendations to track these costs better nationwide and improve reporting on heat-related deaths and lost work time .
• When: findings must be published within four years after the law is enacted, with data made available for public use .
