Disapproval of California vehicle emissions waiver
Congress cancels the Environmental Protection Agency (EPA) waiver that let California enforce stricter greenhouse gas emission standards for new cars. The waiver is voided and has no legal effect.
- Population Scope High Voiding California's waiver directly affects all new-vehicle purchasers and manufacturers operating in California — roughly 39 million residents plus national automakers who design fleets to California standards — well above 25% of the U.S. population in aggregate economic impact.
- Budgetary Magnitude Low The resolution neither authorizes nor appropriates any funds; no dollar amount or funding stream is created or restricted.
- Legal / Regulatory Depth High The resolution extinguishes a standing Environmental Protection Agency (EPA) waiver and reasserts federal Clean Air Act preemption over California vehicle emission standards — a new binding prohibition on state enforcement authority across the regulated population.
- Degree of Discretion Granted Low The resolution is entirely self-executing with no delegated rulemaking, no agency 'may' authority, and no implementation discretion — the waiver is voided by the text itself.
- Implementation & Enforcement Burden Medium No new enforcement infrastructure is created, but federal preemption now bars California from enforcing its greenhouse gas standards, requiring case-by-case legal defense of that preemption against state regulatory actions already in progress.
- Temporal Commitment High The nullification is permanent upon enactment with no expiry or reauthorization trigger, binding future actors until Congress affirmatively acts to restore the waiver.

Summary
This bill uses the Congressional Review Act to formally reject a 2009 Environmental Protection Agency (EPA) decision that allowed California to set its own greenhouse gas emission standards for new cars. If passed, EPA waiver would have no legal force, meaning California could no longer enforce those stricter state vehicle emissions rules under that waiver.
