The bill lowers near-term costs and preserves automaker flexibility by rolling back a federal vehicle emissions standard, but it does so at the expense of higher air pollution, related health and economic harms, and increased regulatory uncertainty and uneven state protections.
Middle-class families, vehicle buyers, and manufacturers: avoid near-term compliance costs from the EPA rule, lowering production and purchase costs and preventing some potential vehicle price increases.
Automakers and consumers: retain flexibility to choose engine and vehicle technologies, avoiding mandated retooling costs and preserving broader model availability and consumer choice.
Urban communities, children, low-income individuals, and the general public: face increased air pollution and related health harms because weakening the EPA standard slows adoption of low-emission technologies and prolongs use of higher-emitting engines.
Taxpayers and local communities: bear higher pollution-related economic costs (higher healthcare spending, lost work days, environmental damages) as emissions reductions are slowed.
Manufacturers, suppliers, and related small businesses: face regulatory uncertainty and disrupted long-term planning because reversing a finalized federal standard complicates investment decisions in cleaner technologies.

Nullifies EPA’s 2024 multi-pollutant vehicle rule and bars EPA from requiring specific vehicle technologies or limiting vehicle availability by engine type, with 24 months to revise regs.
Introduced March 12, 2025 by Michael Dean Crapo · Last progress March 12, 2025
Invalidates the EPA’s 2024 multi-pollutant emissions rule for light- and medium-duty vehicles and changes the Clean Air Act to prevent the EPA from requiring the use of any specific vehicle technology or from producing limited availability of new vehicles based on engine type. It also requires the EPA to revise its motor-vehicle regulations as needed to comply within 24 months of the law taking effect.
