TMTPOST -- U.S. President Donald Trump on Monday singed an executive order to undo what he has labeled the "electric vehicle mandate," or federal regulations, that require increasingly strict vehicle emissions standards over the coming years. Trump claimed the executive order, as part of a larger suite of actions around energy policy, would save the U.S. auto industry and its workers. Such a regulatory rollback means automakers will be able to pay less attention to producing EVs going forward. In a first round of executive order signings Monday, Trump revoked a 2021 executive order signed by his predecessor Joe Biden that had sought to make 50% of new vehicles sold by 2030 be electrified, including both fully electric cars and plug-in hybrids.
