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 asks Congress to overturn an EPA rule that gave California a waiver to set its own greenhouse‑gas emission standards for new motor vehicles beginning with the 2009 model year and later. If the resolution is adopted, the EPA rule would be nullified, preventing California from enforcing those stricter standards. The action would affect the EPA, California’s vehicle‑emissions program, auto manufacturers, and anyone subject to state emissions regulations.
