Disapproval of vehicle emissions waiver

Full Title:
A joint resolution providing for 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".

Summary#

This joint resolution would use the Congressional Review Act to reject an Environmental Protection Agency (EPA) decision that granted California a waiver. The waiver lets California enforce its own greenhouse gas (GHG) limits for new motor vehicles starting with 2009 and later model years. The bill’s broad goal is to undo that EPA waiver decision and stop the rule from taking effect.

  • Main change: If passed, the resolution would disapprove the EPA rule that granted California’s waiver for its GHG vehicle standards.
  • Who introduced it: Senators listed as sponsors include Eric Schmitt, Pete Ricketts, Cynthia Lummis, Jon Husted, Roger Marshall, John Barrasso, Deb Fischer, and Bernie Moreno.
  • Policy area: Federal preemption of state vehicle emission rules and the use of the Congressional Review Act to overturn an agency decision.
  • Legal effect under the Congressional Review Act: A successful disapproval would invalidate the EPA rule and generally block the agency from issuing a new rule in “substantially the same” form without explicit congressional authorization.

What it means for you#

  • Automakers: This could affect which federal or state emissions standards manufacturers must meet when selling new cars nationwide. It may create regulatory uncertainty about whether they must comply with California’s GHG limits in states that follow California rules.
  • Consumers / Car buyers: The resolution could influence vehicle options, fuel economy, or vehicle price changes over time if automakers change designs or offerings in response to differing standards.
  • California state government: The state’s legal ability to enforce its greenhouse gas standards for new vehicles depends on the waiver; disapproval would remove the EPA’s grant of that federal waiver and could limit California’s separate program.
  • Other states that follow California standards: States that adopt California’s standards by law or policy could be affected if the waiver is disapproved, because their authority to enforce the California standards rests on that waiver.
  • Federal agencies (EPA): The EPA would be barred from reissuing a substantially similar rule unless Congress later allows it. The agency might need to revise guidance or enforcement actions tied to the now-disapproved waiver.
  • General public / environment: The resolution does not itself set new emissions rules. Its main effect would be to remove one federal approval that allowed California to require stricter GHG limits for new cars.

Expenses#

No publicly available information.

  • There is no fiscal note or budget estimate provided in the supplied material.
  • Possible costs not estimated here could include agency staff time to respond, legal costs if litigation follows, and compliance costs for manufacturers if standards change. These are not quantified in the available material.

Proponents' View#

  • The bill appears intended to overturn the EPA decision that allowed California to enforce its own GHG vehicle standards.
  • A possible argument for the bill is that it would restore a single national regulatory standard rather than allowing differing state rules, which supporters may view as reducing regulatory complexity for automakers.
  • Another possible rationale is that Congress should decide whether the federal government allows states to set different standards for vehicle GHG emissions rather than leaving that choice to an agency decision.

Opponents' View#

  • One concern is that disapproving the waiver could limit California’s long-standing authority to set stricter vehicle emissions rules and reduce states’ flexibility to address local air quality and climate goals.
  • The bill does not clearly explain how existing state standards or vehicles already sold would be handled, which may create legal or market uncertainty.
  • A possible trade-off is regulatory confusion: automakers and states may face uncertainty about which rules apply, potentially raising compliance costs or delaying emissions-reduction measures.
  • It is unclear how the resolution would affect states that have chosen to follow California standards, and whether litigation would follow, with associated costs and delays.
