Overview
- The EPA finalized the rescission and also removed federal greenhouse-gas standards for light-, medium- and heavy-duty vehicles, effective immediately.
- Agency leaders call the rollback the largest deregulatory action to date, projecting more than $1.3 trillion in savings and an average $2,400 reduction in new-vehicle prices.
- Environmental groups and public-health advocates have filed or announced lawsuits, and California officials pledged to challenge the move to protect state air-quality and climate policies.
- Supporters from conservative and industry-aligned groups praised the decision as restoring affordability and freeing automakers from emissions mandates.
- Analysts report U.S. automakers shifting back toward combustion-engine models as EV sales weaken, while legal arguments are expected to invoke the Supreme Court’s Loper Bright ruling and the earlier Massachusetts v. EPA precedent.
