EPA to Rescind Greenhouse Gas Regulations: Largest Deregulatory Move in U.S. History
The EPA will revoke its finding that greenhouse gas emissions threaten public health and will eliminate emission standards for vehicles. This decision, announced by EPA Administrator Lee Zeldin, follows a 2024 Supreme Court ruling. The action undoes decades of regulation, drawing potential legal challenges.

In a significant policy shift, the U.S. Environmental Protection Agency announced it will retract its finding that greenhouse gas emissions pose a threat to human health. EPA Administrator Lee Zeldin revealed plans to dissolve existing vehicle emission standards, claiming it as the largest deregulatory action in U.S. history.
This decision comes in the wake of a 2024 Supreme Court ruling that limited federal agencies' ability to interpret laws. The EPA, according to Zeldin, lacks the authority to regulate global greenhouse emissions independently and would follow congressional amendments to the Clean Air Act if made.
The move, aimed at dismantling existing greenhouse gas regulations, reverses efforts made since a pivotal 2009 finding during Barack Obama's presidency. Expected to face legal opposition, the repeal would eliminate emission standards for all vehicle categories.
