I 119th CONGRESS 1st Session H. R. 4117 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.

1. Short title This Act may be cited as the Fuel Emissions Freedom Act . 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. 3.
