Official title: Repeal a rule of the Environmental Protection Agency with respect to multi-pollutant emissions standards, to amend the Clean Air Act to ensure that tailpipe regulations do not limit the availability of new motor vehicles, and for other purposes.
Introduced March 12, 2025 by Michael Dean Crapo · Last progress March 12, 2025
The bill trades near-term cost savings and preserved automaker/consumer flexibility by blocking federal vehicle emissions mandates for increased air pollution, health and environmental harms, regulatory uncertainty, and fragmented state-level rules.
Manufacturers and many car buyers face lower near-term production and purchase costs because federal EPA emissions mandates are blocked, avoiding compliance and retooling expenses.
Automakers retain flexibility over engine technologies and consumers keep broader model and powertrain choices because the bill limits federal restrictions on vehicle types.
Drivers and the public will face higher air pollution and related health harms because stronger federal emissions standards are nullified, increasing respiratory illnesses and other pollution-linked health problems.
Prolonging use of higher-emitting engines will increase environmental damages and pollution-related costs (healthcare, lost work days), disproportionately harming low-income communities and racial/ethnic minorities.
Reversing a finalized federal standard creates regulatory uncertainty for automakers and suppliers, complicating long-term planning and investment in cleaner technologies.
Based on analysis of 3 sections of legislative text.
Voids EPA's 2027+ vehicle multi-pollutant rule and bars EPA from requiring specific vehicle technologies or limiting new-vehicle availability by engine type, with EPA-required revisions within 24 months.
Invalidates a recent EPA rule setting multi-pollutant emissions standards for model year 2027+ light- and medium-duty vehicles and stops the EPA from writing vehicle rules that require specific technologies or that restrict availability of new vehicles by engine type. It also amends the Clean Air Act to add an explicit prohibition on technology mandates and requires the EPA to revise any existing regulations to comply within 24 months of enactment.
