Trump to repeal key ruling allowing regulation of planet-heating gases

Climate groups vow to fight rollback of 2009 finding determining CO₂ and other greenhouse gases harm health

In what is set to be its most audacious anti-environment move yet, the Trump administration on Thursday will roll back the mechanism allowing the government to regulate planet-heating pollution, the White House press secretary has told reporters.

President Trump will be joined by EPA Administrator Lee Zeldin to formalize the recession of the 2009 Obama-era endangerment finding," Karoline Leavitt said at a press conference on Tuesday. This will be the largest deregulatory action in American history."
