Kevin Lamarque | ReutersThe Biden administration announced new automobile emissions standards Wednesday that officials called the most ambitious plan ever to cut planet-warming emissions from passenger vehicles. The rules come as sales of electric vehicles, which are needed to meet the standards, have begun to slow. The agency is finalizing the rule as sales of clean vehicles, including plug-in hybrid and fully electric vehicles, hit record highs last year. At the same time, the Democratic president needs cooperation from the auto industry and political support from auto workers, a key political voting bloc. White House press secretary Karine Jean-Pierre said Tuesday that White House officials "don't have any concerns" about the final EPA rule.
