Leaders Praise EPA Proposal to Rescind Endangerment Finding

The U.S. Environmental Protection Agency (EPA) under Administrator Lee Zeldin released a proposal to rescind the 2009 Endangerment Finding on 2025-08-01.

• Main action: The proposal to rescind the 2009 Endangerment Finding would, if finalized, repeal greenhouse gas standards for light-, medium-, and heavy-duty vehicles and heavy-duty engines; the release cites an expected $54 billion in annual savings and notes the Finding has underpinned over $1 trillion in regulations (SBA claims $170 billion in small business savings). The proposal was announced by Administrator Lee Zeldin and referenced by President Trump and multiple Cabinet officials.
• Background and stakeholders: Numerous administration officials (e.g., Secretary Chris Wright, Secretary Doug Burgum), Congressional Republicans, and stakeholder groups (e.g., API, ATA, CEI, Heartland Institute, America First Policy Institute) issued supportive statements; the release also states that without the Endangerment Finding EPA would lack authority under Section 202(a) of the Clean Air Act to set GHG standards for new motor vehicles.
