The bill trades short-term, broad-based cost relief for drivers and reduced compliance burdens for automakers against substantial increases in air pollution, greenhouse gas emissions, long-term consumer and health costs, and legal and state-level regulatory disruption.
Drivers and vehicle owners (millions of taxpayers) would face lower upfront vehicle prices and fewer regulatory costs when buying or modifying cars because federal emissions/fuel-economy mandates are eliminated.
Auto manufacturers and suppliers (including small and medium businesses) would face reduced compliance costs and fewer overlapping federal requirements, lowering production costs and easing supply-chain burdens.
Industry and some regulators (EPA, state/local governments) could experience regulatory simplification and potentially greater regulatory certainty in some respects, which may encourage investment in U.S. manufacturing.
Communities across the country (urban, rural, children, and people with respiratory vulnerabilities) would face higher air pollution and increased health risks — more asthma, respiratory and cardiovascular harms — from weaker or eliminated vehicle emissions standards.
All Americans would see higher greenhouse gas emissions and weakened progress on climate goals if national vehicle emissions and fuel-economy mandates are removed, worsening long-term climate impacts.
Consumers and taxpayers would likely face higher long-term costs from increased gasoline consumption, higher fuel spending over time, and greater health-care and environmental cleanup costs tied to worse air quality.
Repeals federal motor vehicle emissions and fuel-economy laws and bans both federal and state fuel-emission standards going forward. It voids existing related federal and state regulations and waivers, removes statutory authority used to set vehicle emissions and fuel economy rules, and prevents any future standard from being established or enforced at either the federal or state level.
