What it does
This resolution uses the Congressional Review Act to nullify an EPA decision that granted California a waiver allowing it to set its own stricter greenhouse gas emission standards for cars and trucks starting with 2009 model years. If passed, California and the roughly 17 states that follow its standards would lose the legal authority to enforce those tougher rules. The primary beneficiaries are automakers who prefer a single, less stringent national standard over California's stricter requirements.
Why we flagged it
The resolution's sole function is to strip California of its longstanding Clean Air Act waiver authority, effectively weakening vehicle emissions standards across roughly a third of the U.S. market.
What the text implies
- Because approximately 17 other states have adopted California's vehicle emission standards under Section 177 of the Clean Air Act, nullifying this waiver could simultaneously invalidate those states' standards, affecting well over 100 million residents beyond California.
- A successful CRA disapproval would bar the EPA from issuing a 'substantially similar' rule in the future without new congressional authorization, potentially locking in weaker standards long-term.
