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 proposes to use the Congressional Review Act to nullify a specific rule issued by the Environmental Protection Agency (EPA). The targeted EPA rule, published in 2009, granted California a waiver of Clean Air Act preemption , allowing the state to establish its own greenhouse gas emission standards for new motor vehicles from the 2009 model year and beyond. This waiver enabled California to implement stricter emissions regulations than federal standards. If Congress passes and the President signs this resolution, the EPA's decision to grant California this waiver would be overturned , rendering the rule without force or effect. Consequently, California would lose its authority to enforce its distinct state-level greenhouse gas emission standards for motor vehicles, potentially impacting vehicle emissions regulations nationwide.
