"At stake in the lawsuit is the single biggest effort by the United States to fight the climate crisis."
"Led by California, nearly two dozen states sued the Trump administration on Wednesday over its reversal of fuel-efficiency standards for cars and trucks, arguing that the move is based on erroneous science, and endangers public health.
The lawsuit escalates a standoff between President Trump, who has moved to undo a long list of environmental regulations since taking office, and a coalition of Democratic states, which have gone to court to stop him.
President Trump’s attempt to weaken future fuel economy standards — undoing what would have been the single biggest effort by the United States to fight the climate crisis — has been especially contentious and messy. Mr. Trump has called the rollback the crowning deregulatory achievement of his tenure, a move that he has said will save lives, lift the economy and help the auto industry."
