Trump revokes landmark ruling that greenhouse gases endanger public health

The so-called 2009 "endangerment finding" concluded that a range of greenhouse gases were a threat to public health. It's become the legal bedrock of federal efforts to rein in emissions, especially in vehicles, News.az reports, citing BBC.

The White House called the reversal the "largest deregulation in American history", saying it would make cars cheaper, bringing down costs for automakers by $2,400 per vehicle.

Environmental groups say the move is by far the most significant rollback on climate change yet attempted and are set to challenge it in the courts.
