Clean car standards legal resources

Clean Car standards are reducing climate pollution, protecting our lives and health, creating American jobs, and saving us money at the gas pump. But protective standards at both the federal and state level are being challenged in court.

EDF is defending rigorous clean car standards in court, and we will keep fighting for standards that reduce health-harming and climate destabilizing pollution.

There are currently court cases challenging: EPA’s greenhouse gas standards for model years 2023 to 2026; EPA’s reinstatement of a Clean Air Act waiver for California’s Advanced Clean Car standards; and the National Highway Traffic Safety Administration’s (NHTSA) fuel economy standards for model years 2024 to 2026. EDF is participating in each of these cases in defense of the challenged actions.
