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 and Engine Pollution Control Standards; Advanced Clean Cars II; Waiver of Preemption; Notice of Decision".

This resolution cancels an Environmental Protection Agency (EPA) notice that granted California permission (a “waiver”) to enforce its Advanced Clean Cars II rules. Under the Clean Air Act, California can ask for a waiver because states are usually blocked from setting their own vehicle emission standards. By nullifying the EPA’s notice, California would no longer have that permission for these rules . The EPA notice being canceled was published on January 6, 2025 .

In everyday terms, this means California’s stricter car and engine pollution rules under “Advanced Clean Cars II” would not be allowed, unless a new waiver is approved in the future .

• Key points:
  • Who is affected: California, car makers, and car buyers in the state .
  • What changes: The EPA’s decision that allowed California to enforce its Advanced Clean Cars II standards is overturned, removing that permission .
  • Timing: It targets the EPA notice published January 6, 2025 .
