The U.S. government’s most ambitious plan ever to slash planet-warming greenhouse gas emissions from passenger vehicles faces skepticism both about how realistic it is and whether it goes far enough.
The Environmental Protection Agency in April announced new strict emissions limits that the agency says are vital to slowing climate change as people around the globe endure record-high temperatures, raging wildfires and intense storms.The EPA says the industry could meet the limits if 67% of new-vehicle sales are electric by 2032, a pace the auto industry calls unrealistic. However, the new rule would not require automakers to boost electric vehicle sales directly.
Peter Slowik, a senior EV researcher with the nonprofit International Council on Clean Transportation, has calculated that to cut emissions enough to reach Paris Agreement goals, the proportion of new electric and plug-in hybrid vehicles sold would have to reach 67% by 2030. The EPA has projected 60% by then.
In addition, Slowik cautioned, carbon emissions from new gasoline vehicles would have to drop 3.5% each year from 2027 to 2032. The EPA’s preferred regulation doesn’t set reductions for gas vehicles. But fuel economy standards recently proposed by the National Highway Traffic Safety Administration could.The EPA contends its proposal will significantly reduce pollution.

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