EPA Just Announced the Largest Deregulatory Action in U.S. History
On July 29, 2025, the U.S. Environmental Protection Agency (EPA) proposed to repeal the 2009 Endangerment Finding — the scientific and legal foundation that classifies six greenhouse gases as threats to public health and the environment and authorizes their regulation under the Clean Air Act. This pivotal move effectively aims to eliminate regulations on carbon emissions from key sources like vehicles, power plants, and the oil and gas industry[1][2][3][4].
What Is the Endangerment Finding?
Issued in 2009, the Endangerment Finding was a landmark scientific assessment adopted in response to a Supreme Court ruling (Massachusetts v. EPA). It recognized greenhouse gases as harmful pollutants that contribute to climate change, thereby empowering the EPA to regulate emissions to protect public health and the environment. It paved the way for more than $1 trillion in regulations, including electric vehicle mandates and emissions standards for cars and trucks[1][3].
Why Is the EPA Revoking It Now?
EPA Administrator Lee Zeldin criticized the Endangerment Finding as imposing excessive regulatory costs that he claims threaten economic growth. Speaking on a conservative podcast, Zeldin asserted that repealing the finding would save Americans over a trillion dollars and restore consumer choice in the automotive market by removing mandates seen as burdensome[2][3].
Implications of the Repeal
– Regulatory Rollback: Revoking the Endangerment Finding removes the legal basis for regulating greenhouse gas emissions nationwide, unraveling critical climate protections established over the past 15 years[4].
– Public Health at Risk: Environmental experts and former EPA officials warn this decision is a “calculated disregard” of science that will lead to widespread harm, disproportionately impacting vulnerable communities[4].
– Impact on Vehicles and Pollution: The repeal would suspend vehicle emissions standards designed to reduce automotive pollution, potentially increasing carbon output and reversing advances in air quality[2][4].
– Economic Debate: Proponents argue this deregulation will reduce costs for consumers and industries. Opponents stress the long-term risks and costs posed by unchecked climate pollution.
Who Is Responding?
The Environmental Protection Network, representing hundreds of former EPA scientists and officials, condemned the move as an abdication of EPA’s statutory duty to protect health and environment. The Clean Air Task Force called the step “drastic,” emphasizing the continued need for evidence-based pollution regulation[4].
What’s Next?
The EPA’s proposal is currently open for public comment before any final action. This decision will likely ignite significant legal and policy battles given its profound implications on climate policy and public health protections.
Why This Matters to You
Whether you live in a city or rural area, these regulations influence air quality, climate stability, and economic costs tied to transportation and energy. The future of U.S. climate leadership and environmental health hangs in the balance as this story unfolds.

What are the potential environmental impacts of revoking the Endangerment Finding?
Experts warn that revoking the finding could lead to increased greenhouse gas emissions, higher pollution levels, and a reversal of progress made in air quality improvements, ultimately contributing to more severe climate change impacts.
How can the public participate in this process?
The EPA’s proposal is open for public comment. Citizens can submit feedback through the EPA’s official comment portal before the final decision is made, influencing the regulatory outcome.
