This joint resolution would reject an Environmental Protection Agency rule that allows California to set its own vehicle pollution standards under its Advanced Clean Car Program. The rule, originally published in March 2022, grants California a waiver from federal preemption, enabling the state to enforce stricter emissions standards than federal requirements. If passed, this resolution would nullify the EPA rule, preventing California from implementing its own vehicle pollution control standards. The measure uses the Congressional Review Act, a fast-track process that allows Congress to disapprove federal regulations. This resolution would primarily affect California's ability to regulate vehicle emissions and could impact automakers operating in the state, as well as consumers purchasing vehicles there.
