The administration’s actions will give the liberal state more leverage in discussions between the auto industry and federal and state officials over national mileage and greenhouse gas emission standards for cars and SUVs. Thirteen states and the District of Columbia have signed onto California’s tailpipe emission standards: Collectively they represent 36 percent of the U.S. auto market.
“The transportation sector is the biggest contributor to greenhouse gases in our economy — which means it can and must be a big part of the climate solution,” Transportation Secretary Pete Buttigieg said in a statement. “This proposed rule would be an important step towards protecting public health and combating climate change.”
A year ago, EPA and the National Highway Traffic Safety Administration finalized a rule to improve average fuel efficiency by 1.5 percent per year, compared with a nearly 5 percent annual increase set to take effect under Obama administration rules. It will take a few months for the Biden administration to restore California’s authority to impose greenhouse gas standards on cars and trucks. The president has instructed the agencies to develop a new set of federal mileage and greenhouse gas standards by July.
Biden’s EPA administrator, Michael Regan, told lawmakers Wednesday that the administration will propose nationwide standards for tailpipe emissions in mid-July.
“States like California have historically the right to lead the way,” Regan said. “The federal government can indeed learn from states, and that’s what we plan to continue to do.”
Dan Becker, who directs the Center for Biological Diversity’s Safe Climate Transport Campaign, said in a phone interview that California and its other state allies can serve a key role in the negotiations once they are again empowered to “protect their people more than the federal government requires.”
“California has provided a backstop when the federal government refused to adequately protect people from auto pollution,” he added.
