For the second time in a half decade, President Donald Trump is slashing federal fuel economy standards in a bid to lower sticker prices for car buyers.
The White House announced on Thursday, Feb. 12, that the U.S. Environmental Protection Agency has finalized a new rule that will rescind an Obama-era scientific finding that greenhouse gas emissions from cars and other sources pose a threat to public health.
The 2009 finding, known as the endangerment finding, has provided the legal basis for the federal government’s most ambitious efforts to slash planet-warming car emissions, including rules that currently require automakers to achieve an average of more than 50 miles per gallon for all the cars across their fleets.
