The administration of President Donald Trump on Thursday plans to announce the repeal of a scientific finding that greenhouse gas emissions endanger human health, removing the legal basis for federal climate regulations.

The Trump administration is preparing what environmental experts are calling one of the most sweeping regulatory rollbacks in modern history. The president plans to revoke the EPA's legal authority to regulate carbon emissions on Thursday.

The Trump administration says greenhouse gases emitted from sources like cars, trucks and power plants will no longer by regulated by the federal government.

Officials for the Environmental Protection Agency are working to end a 2009 declaration that says climate change is a danger to public health.

The endangerment finding gives the EPA authority to regulate greenhouse gases by deeming they pose a risk to public health and welfare.

EPA's reversal of the formal 2009 scientific finding that greenhouse gases threaten humans looks slated to land this week, per the WSJ, other reports, and people tracking the move. Why it matters: Rescinding the "endangerment finding" is the Trump administration's most direct effort yet to rip out climate regulations root and branch — and make it harder for a successor to impose new ones.
