What it does
This resolution disapproves an EPA decision from 2009 that allowed California to set its own vehicle greenhouse gas emission standards stricter than federal rules. If passed, it would nullify that EPA waiver, preventing California from enforcing tougher emissions standards on new vehicles and reverting to federal baseline rules.
Why we flagged it
This is a Congressional Review Act (CRA) disapproval resolution targeting a specific EPA environmental rule. Its operative effect is to eliminate a state's authority to enforce stricter vehicle emissions standards, functionally deregulating vehicle greenhouse gas emissions at the state level.
What the text implies
- Nullifying the 2009 waiver does not merely revert to 2009 federal standards; it removes California's ongoing authority to update its standards for 2009 and subsequent model years, locking in federal baseline for all future vehicles unless Congress acts.
- Other states that have adopted California's emission standards under Clean Air Act Section 209 would lose the ability to enforce those standards, as they depend on California's waiver to set standards stricter than federal rules.
