EPA proposes repeal of 2009 ruling that allowed regulation of greenhouse gases, sparking debate.

The U.S. Environmental Protection Agency (EPA) is proposing to repeal the 2009 "Endangerment Finding," which allowed the EPA to regulate greenhouse gas (GHG) emissions under the Clean Air Act. This move could eliminate the EPA's authority to regulate GHG emissions from vehicles and industries, leading to potential legal challenges and uncertainty. Public comments on the proposal are being accepted until September 15, 2025. The decision has sparked debate, with critics arguing it undermines established science on climate change and its impact on public health.
