President Joe Biden sought to project unity with the auto industry Thursday as he signed an executive order at a White House event setting a target for half of all new vehicles sold in the United States to be electric or carbon-free by 2030.

CEOs of the Big Three U.S. automakers, along with the president of the United Auto Workers union, flanked Biden as he announced the new voluntary goal and unveiled stricter binding standards for fuel efficiency and tailpipe emissions for cars and light trucks.
