Federal authorities announce intentions to rescind Obama administration's climate risk determination
Zeldin Proposes to Rescind Obama-Era Endangerment Finding, Sparking Debate on Climate and Environmental Policy
Lee Zeldin, Administrator of the US Environmental Protection Agency (EPA), has announced plans to rescind the Obama-era endangerment finding declaration, a move that could have significant implications for U.S. climate and environmental policy.
The 2009 endangerment finding declared that greenhouse gases such as carbon dioxide and methane endanger public health, providing the legal basis for many climate regulations under the Clean Air Act, including vehicle emission standards and electric vehicle mandates.
If finalized, Zeldin's proposal would eliminate over $1 trillion in federal regulations related to greenhouse gas emissions, potentially repealing all regulations on motor vehicles and engines aimed at reducing emissions. This action is described by Zeldin as delivering "a dagger into the heart of the climate change religion."
The potential impacts include:
- Repeal of greenhouse gas emission regulations for motor vehicles, including standards for cars, trucks, and heavy-duty vehicles.
- Restoration of what proponents call "consumer choice," allowing Americans to purchase vehicles without government-mandated emissions constraints.
- Eliminating estimated regulatory costs exceeding $1 trillion, with claimed savings of more than $54 billion annually to businesses and families.
However, the move faces criticism from clean transportation advocates who warn that rescinding these standards threatens jobs in clean transportation sectors and could stall progress toward vehicle electrification and emissions reductions. The transportation industry and environmental groups argue that the technology to meet the original standards already exists and that regulatory rollback could negatively impact public health and climate goals.
Fred Krupp, President of the Environmental Defense Fund, stated that without enforced limits on pollution, there would be more of it, making life more expensive and dangerous. He warned that the stakes of repealing the Obama-era endangerment finding are high for Americans.
The proposed change would rescind regulations limiting air pollutant emissions from sources including chemical plants, utilities, and steel mills. The repeal of the Obama-era endangerment finding is expected to face a public comment period and potential legal challenges from environmental groups.
The announcement of the plan to rescind the Obama-era endangerment finding was made by Lee Zeldin on the "Ruthless" podcast on Tuesday, May 1, 2025. Zeldin stated that the proposal would save Americans over $54 billion annually. According to Zeldin, Administrator of the EPA, the Obama administration stated that carbon dioxide, when mixed with other greenhouse gases, contributes to climate change.
The endangerment finding declaration serves as the legal foundation for a host of climate regulations. The proposed repeal of the endangerment finding is being characterized as the "largest deregulatory action in the history of America." The proposal aims to scale back regulations such as former President Joe Biden's electric vehicle mandate.

- The proposal by Lee Zeldin, EPA Administrator, aims to rescind the Obama-era endangerment finding declaration, a decision that could terminate over $1 trillion in federal regulations related to greenhouse gas emissions, including those from motor vehicles.
- The potential deregulation could lead to the repeal of greenhouse gas emission regulations for motor vehicles, such as standards for cars, trucks, and heavy-duty vehicles, which may be deemed a boost to consumer choice but could stall progress toward vehicle electrification and emissions reductions.
- The repeal of greenhouse gas emission regulations could have significant implications for the environment, potentially negatively impacting public health and climate goals, as warned by environmental groups like the Environmental Defense Fund.
