What this bill does
In plain words · AI-written from the official summaryBlocks EPA's approval of California's vehicle pollution rules
This joint resolution would reject a recent EPA decision that allowed California to set its own vehicle pollution and emission standards through a program called Advanced Clean Cars II. Under federal law, California can request special permission (called a waiver) to create stricter pollution rules than the federal government requires. The EPA granted that request, but this resolution would reverse that decision.
How it affects you
If this passes, California would lose the ability to enforce its vehicle pollution standards that go beyond federal requirements. This directly affects people in California—including car buyers, drivers, and communities concerned about air quality—since the state would no longer be allowed to implement its stricter rules. The resolution also affects automakers that build vehicles for California's market.
Read the official summary (Introduced in Senate, Apr 4, 2025)
This joint resolution nullifies the Environmental Protection Agency notice titled California State Motor Vehicle and Engine Pollution Control Standards; Advanced Clean Cars II; Waiver of Preemption; Notice of Decision (90 Fed. Reg. 642) and published on January 6, 2025. Among other elements, the notice grants the California Air Resources Board request for a waiver for its Advanced Clean Cars II (ACC II) regulations. (Under the Clean Air Act, California may seek waivers of the preemption prohibiting states from enacting certain emission standards.)
