The EPA's ambitious plan to cut auto emissions to slow climate change runs into skepticism

The U.S. government’s most ambitious plan ever to slash planet-warming greenhouse gas emissions from passenger vehicles faces skepticism about how realistic it is and whether it goes far enough. The Environmental Protection Agency in April announced new strict emissions limits that it says are vital to slowing climate change. The EPA says the industry could meet the limits if 67% of new-vehicle sales are electric by 2032. The auto industry says that pace is unrealistic. Even if the industry boosts EV sales to EPA recommendations, any reduction in pollution could prove more modest than the agency expects. The Associated Press estimates that nearly 80% of vehicles being driven in the U.S. would still run on gasoline or diesel fuel.
