What's Happening?
On February 12, 2026, the U.S. Environmental Protection Agency (EPA) announced a final rule rescinding the 2009 Greenhouse Gas (GHG) Endangerment Finding for motor vehicles. This decision repeals all GHG emission standards and associated compliance measures
for light-, medium-, and heavy-duty vehicles under the Clean Air Act. The rule will take effect 60 days after its publication in the Federal Register. The Endangerment Finding was a cornerstone for regulating GHG emissions from mobile sources, and its revocation could affect other EPA GHG regulations. The EPA argues that the Endangerment Finding exceeded its authority under the Clean Air Act, citing recent U.S. Supreme Court case law. The agency claims that eliminating U.S. vehicle GHG emissions would have a negligible impact on global climate indicators.
Why It's Important?
The rescission of the Endangerment Finding could have significant implications for U.S. climate policy and industries subject to Clean Air Act regulations. The automotive, utilities, and oil and gas sectors, as well as electric vehicle manufacturers and alternative fuel producers, may be affected. The decision could lead to increased litigation, as numerous groups have announced plans to challenge the rule. The EPA's stance may also influence state laws and regulations related to vehicle emissions. This move reflects a broader trend of deregulation under the current administration, potentially impacting the U.S.'s ability to meet international climate commitments.
What's Next?
Stakeholders should monitor upcoming litigation and assess the implications of the rule for other EPA, state, or international GHG regulations. The EPA is also considering revoking GHG emission regulations for power plants and may reconsider its Aircraft GHG Endangerment Finding. The agency's reinterpretation of statutory terms could affect regulations for stationary sources and aircraft. The decision may also impact preemption of state law and federal common law claims related to vehicle emissions.
