HR 4117 Re-checks Congress.gov for new actions and updates the bill's status, and fills in any sponsors, committees, or related bills that are missing. It does not re-pull sponsors/cosponsors/committees/related — those rarely change — and it skips all work if nothing has changed upstream, so it's cheap to click.
To amend the Clean Air Act to repeal the establishment of motor vehicle emission and fuel standards, and for other purposes.
Summary
This bill would repeal federal motor vehicle emission standards established under the Clean Air Act and federal fuel economy standards under Title 49. It would nullify all existing federal and state regulations issued under these provisions and prevent both the federal government and individual states from establishing new emission or fuel economy standards for motor vehicles. The bill would also eliminate California's and other states' ability to set vehicle emission standards separate from federal standards. All references to these standards in federal law and regulations would be removed and deemed unenforceable.

IN THE HOUSE OF REPRESENTATIVES
June 24, 2025
Mr. Williams of Texas (for himself, Mr. Cloud, and Mr. Gill of Texas) introduced the following bill; which was referred to the Committee on Energy and Commerce
A BILL
To amend the Clean Air Act to repeal the establishment of motor vehicle emission and fuel standards, and for other purposes.
Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
This Act may be cited as the “Fuel Emissions Freedom Act”.
SEC. 2. FINDINGS.
Congress finds the following:
(1) Fuel emissions regulations increase costs for consumers and manufacturers.
(2) Overlapping and ever-changing fuel emissions standards, whether imposed by the Environmental Protection Agency, the State of California, or through Corporate Average Fuel Economy regulations, create long-term uncertainty for manufacturers.
(3) This fragmented regulatory environment stifles innovation, disrupts supply chains, and burdens manufacturers and businesses, especially small and medium-sized auto suppliers.
(4) Conflicting fuel emissions standards force manufacturers to comply with multiple sets of costly and inconsistent regulations, further reducing efficiency and raising production costs, which are ultimately passed onto the consumer.
(5) Eliminating fuel emissions standards at the Federal and State level will help restore regulatory certainty, lower costs for families, and strengthen manufacturing in the United States to ensure economic freedom.
SEC. 3. REPEAL AND PREEMPTION OF CERTAIN EMISSION STANDARDS.
(a) Motor Vehicle Emission and Fuel Standards Under Clean Air Act.—
