WASHINGTON — Declaring the U.S. must “move fast” to win the carmaking future, President Joe Biden on Thursday touted a commitment from the auto industry to make electric vehicles up to half of U.S. sales by the end of the decade.

Biden wants automakers to raise gas mileage and cut tailpipe pollution between now and model year 2026. That would mark a significant step toward meeting his pledge to cut emissions and battle climate change as he pushes a history-making shift in the U.S. from internal combustion engines to battery-powered vehicles.

He also urged that the components needed to make that sweeping change — from batteries to semi-conductors — be made in the United States, reflecting a balance to gain both industry and union support for the environmental effort, with the future promise of new jobs and billions in new federal investments in electric vehicles.

Pointing to electric vehicles parked on the White House South Lawn, the president declared them a “vision of the future that is now beginning to happen.”

“The question is whether we lead or fall behind in the race for the future,” he said, “Folks, the rest of the world is moving ahead. We have to catch up.”

Earlier Thursday, the administration announced there would be new mileage and anti-pollution standards from the Environmental Protection Agency and Transportation Department, part of Biden’s goal to cut U.S. greenhouse gas emissions in half by 2030. It said the auto industry had agreed to a target that 40% to 50% of new vehicle sales be electric by 2030.

Both the regulatory standards and the automakers’ voluntary target were included in an executive order that Biden signed as the gathering of auto industry leaders and lawmakers applauded.

The standards, which have to go through the regulatory process including public comments, would reverse fuel economy and anti-pollution rollbacks done under President Donald Trump. At that time, the increases were reduced to 1.5% annually through model year 2026.

Still, it remained to be seen how quickly consumers would be willing to embrace higher mileage, lower-emission vehicles over less fuel-efficient SUVs, currently the industry’s top seller. The 2030 EV targets ultimately are nonbinding, and the industry stressed that billions of dollars in electric-vehicle investments in legislation pending in Congress will be vital to meeting those goals.

Only 2.2% of new vehicle sales were fully electric vehicles through June, according to Edmunds.com estimates. That’s up from 1.4% at the same time last year.

Biden has long declared himself “a car guy,” his blue collar political persona intertwined with support for union workers and his role, as vice president, in steadying the auto industry after the economic collapse in 2008. He also joked to Mary Barra, the CEO of General Motors, that he wanted to reserve a test drive.

“I have a commitment from Mary: When they make the first electric Corvette, I get to drive it,” Biden said. “Right, Mary? You think I’m kidding. I’m not kidding.”

Transportation is the single biggest U.S. contributor to climate change.

Autos in the U.S. spewed 824 million tons of heat-trapping carbon dioxide in 2019, about 14% of total U.S. emissions, according to the EPA.
