Major Automakers Urge EPA to Scale Back Tough Tailpipe Emissions Rules

A coalition representing nearly all major automakers has called on the Environmental Protection Agency (EPA) to ease vehicle emissions standards set under President Joe Biden. In a filing Tuesday, the Alliance for Automotive Innovation argued that the current rules, which require steep cuts in tailpipe emissions and rapid adoption of electric vehicles (EVs), are no longer feasible given market realities, infrastructure gaps, supply chain hurdles, and rising affordability concerns. The Biden-era regulations aim to cut fleetwide passenger vehicle emissions nearly 50% by 2032, with the EPA projecting that between 35% and 56% of new vehicles sold by then would need to be electric. Automakers, however, warn that recent policy changes signed by President Donald Trump, including the expiration of the $7,500 EV tax credit on September 30 and potential loss of battery production tax credits worth $3,000 per vehicle, will drive up EV costs and dampen consumer demand. Industry leaders cautioned that these developments threaten billions in EV investments and the broader supply chain. While environmental groups and Democrats push the EPA to defend existing rules, automakers say revisions are critical to provide regulatory certainty and align targets with real-world challenges.
