The 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 new rules relax initial tailpipe limits proposed last year but eventually get close to the same strict standards set out by the Environmental Protection Agency. The rules come as sales of electric vehicles, which are needed to meet the standards, have begun to slow.
“Let me be clear: Our final rule delivers the same, if not more, pollution reduction than we set out in our proposal,’’ EPA Administrator Michael Regan told reporters. In addition to carbon pollution, the final standards also will reduce other serious air pollution that contributes to heart attacks, respiratory illnesses, aggravated asthma and decreased lung function, Regan said.
