What it does
This bill directs the National Oceanic and Atmospheric Administration (NOAA) to conduct a comprehensive economic study quantifying the financial costs of extreme heat in the United States—including deaths, injuries, property damage, medical expenses, lost productivity, and infrastructure impacts—and to publish findings on a public website within four years. The study will coordinate across federal agencies and may use outside research organizations, with $3.5 million authorized for the work.
Why we flagged it
The bill's sole operative mechanism is a mandate to study and publicly disclose economic data on extreme heat impacts. It creates no new regulations, subsidies, or restrictions—only a requirement for government to gather and share information in the public interest.
What the text implies
- Study findings may inform future climate adaptation policy and infrastructure investment decisions, potentially shifting public and private spending toward heat resilience.
- Quantifying the economic value of heat-related deaths and injuries may influence cost-benefit analyses in regulatory proceedings and litigation.
- Public disclosure of heat-related insurance claims data may affect underwriting practices and premium-setting in health, property, and workers' compensation markets.
- Labor productivity loss data may support future workplace heat-safety regulations or OSHA standards.

Who it affects
Citizens gain access to comprehensive, publicly available data on the true economic cost of extreme heat—information currently fragmented across agencies and private insurers. This transparency enables informed advocacy, policy debate, and individual decision-making about heat risk, and supports public health planning.
