Providing congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "California State Motor Vehicle Pollution Control Standards; Notice of Decision Granting a Waiver of Clean Air Act Preemption for California's 2009 and Subsequent Model Year Greenhouse Gas Emission Standards for New Motor Vehicles".

This joint resolution seeks to overturn a specific rule issued by the Environmental Protection Agency that allowed California to set its own stricter greenhouse gas emission standards for new motor vehicles. If passed, the measure would cancel the EPA's waiver of federal preemption, requiring California and other states to follow uniform national vehicle emission rules instead of maintaining unique state-level standards. The bill directly affects the EPA, California's regulatory authority, and the automotive industry by eliminating the legal basis for California's independent pollution control policies. It is a procedural action that would render the contested rule ineffective without force or effect.
