Repeals federal vehicle emissions and fuel-economy statutory authority, eliminates state waiver power, and voids existing federal and state emission/fuel standards.
The bill reduces federal regulatory burdens and short-term costs for automakers and some consumers while giving states certain regulatory flexibilities, but it likely increases air pollution, harms public health, slows clean-vehicle innovation, and shifts substantial long-term health and economic costs onto taxpayers and communities.
Manufacturers and small- and medium-sized auto suppliers face fewer overlapping federal regulatory requirements, reducing compliance and administrative costs and easing production burdens.
Drivers and vehicle-buying families may see lower upfront vehicle prices and reduced regulatory-driven compliance costs passed through to consumers in the near term.
States regain certain regulatory flexibility and clearer authority to set vehicle-related policies (including without needing prior EPA waivers), giving state governments more direct control over transportation rules.
Urban, rural, and suburban communities (especially children, the elderly, and people with respiratory conditions) will likely experience increased air pollution and worsened public health outcomes (e.g., more asthma and cardiovascular disease) if federal emissions limits are removed.
Taxpayers and families could face higher long-term economic costs from increased healthcare spending, lost productivity, and environmental remediation tied to greater vehicle pollution; reduced efficiency standards may also raise fuel costs over time.
The bill undermines incentives for cleaner vehicle technologies and fuels, threatening investment, slowing adoption of fuel-efficient and low-emission vehicles, and risking jobs and market development in clean-energy and advanced-vehicle sectors.

Official title: To amend the Clean Air Act to repeal the establishment of motor vehicle emission and fuel standards, and for other purposes.
Introduced June 24, 2025 by Roger Williams · Last progress June 24, 2025
Repeals federal authority to set motor vehicle fuel emissions and corporate average fuel economy (CAFE) standards, removes the Clean Air Act waiver that let states adopt their own vehicle emission rules, and invalidates existing federal and state rules and waivers. It bars the federal government and states from establishing, enforcing, or maintaining fuel-emission standards for motor vehicles going forward, and declares prior references to those standards void on enactment.
