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 2009 Environmental Protection Agency rule that allowed California to set its own stricter greenhouse gas emission standards for new motor vehicles. By using a congressional disapproval process, the bill aims to cancel this waiver, which would force California to adopt the same vehicle pollution rules as the rest of the United States. If passed, the measure would directly affect vehicle manufacturers and the state of California by eliminating their ability to enforce unique environmental regulations for cars and trucks. The legislation does not propose new emission limits but instead restores the federal Clean Air Act's preemption over state-level vehicle standards.
