Trump Era EPA Targets Repeal of CO₂ Endangerment Finding – A NMSC View

Industry Insights from Next Move Strategy Consulting

On July 29, 2025, EPA Administrator Lee Zeldin announced a proposal to overturn the agency’s seminal 2009 endangerment finding, which declared that carbon dioxide and other greenhouse gases “threaten the public health and welfare of current and future generations.” This action would dismantle the legal underpinning for vehicle and power plant emissions limits under the Clean Air Act, a move Zeldin heralded as “the largest deregulatory action in the history of America.”

A Bold Departure from Established Climate Safeguards

By targeting the endangerment finding, the EPA aims to:

• Eliminate Vehicle Emissions Rules: Revoke all greenhouse gas standards for light , medium  and heavy duty vehicles derived from the 2009 finding.

• Advance Deregulation: Fulfill President Trump’s broader agenda to boost oil, gas and coal production while scaling back support for renewables and electric vehicles.

• Challenge Scientific Consensus: Reverse an Obama era determination based on decades of climate research linking greenhouse gases to health risks.

• Spark Legal Battles: Invite immediate litigation over the EPA’s authority under the Clean Air Act and the major questions doctrine.

Redefining the Climate Policy Landscape

If upheld, this repeal would mark a seismic shift in U.S. climate governance, erasing critical federal tools for mitigating air quality impacts, extreme weather risks and public health threats. As states and private actors weigh their next moves, the decision may reshuffle incentives for electric vehicle adoption and renewable energy investment.
