Protect America from CARB Act of 2026

The Protect America from CARB Act of 2026 amends the Clean Air Act to require that state emissions standards receive approval from four federal cabinet secretaries before they can be implemented. Specifically, states must obtain concurrence from the Secretaries of Agriculture, Energy, Interior, and Transportation in addition to completing standard public notice and hearing procedures. This change directly affects state environmental agencies seeking waivers or authorizations for air quality rules, adding a layer of federal oversight to the process. The new requirements apply to any waiver requests submitted on or after the date the bill is enacted into law.
