President Donald Trump on Wednesday barred California from setting its own vehicle emissions standards. The Trump Administration is revoking California's Federal Waiver on emissions in order to produce far less expensive cars for the consumer, while at the same time making the cars substantially SAFER," Trump tweeted. The widely anticipated move comes as the White House also prepares to roll back the strict Corporate Average Fuel Economy, or CAFE, standards set under President Barack Obama. Using its authority to set emissions targets, California had set even tougher standards that effectively required the auto industry to begin rolling out fleets of zero-emissions vehicles, including plug-in hybrids, pure battery-electric vehicles and hydrogen-powered cars. California has already filed legal efforts to forestall such a move and has been joined by other states that have adopted the stricter California mandates. California originally was granted authority to set tougher standards as an acknowledgment of the poor air quality in cities such as Los Angeles. Responding to reports that the White House was preparing to follow through on plans to eliminate that waiver, California Governor Gavin Newsom issued a statement warning the move "could have devastating consequences for our kids' health and the air we breathe."
