The president is reinstating Obama-era rules on vehicle pollution, but climate advocates say that may not be enough.
President Joe Biden is launching a push on Thursday to curb vehicle emissions and set a benchmark for the U.S. to begin phasing out gas vehicles. Biden is expected to sign an executive order setting a goal for half of all vehicles sold in the United States to be electric by 2030, which will likely play a key role in helping the U.S. meet Biden’s climate goals. He is also expected to reinstate and tighten tailpipe emission standards set under President Barack Obama (but rolled back by Trump) to cut greenhouse gas emissions and ramp up vehicle efficiency. The transportation sector is the largest source of greenhouse gas emissions in the U.S., making up 29 percent of emissions in 2019, according to the Environmental Protection Agency (EPA). Without swift vehicle electrification, climate goals set by the administration like cutting emissions to 50 percent of 2005 levels by 2030 will be hard to reach, experts say, Still, Biden’s announced goal for vehicle electrification will be difficult to achieve, logistically and politically. “There’s a battle on every front. There’s a battle in Congress. There’s a battle in the courts. There’s a battle against time,” Jody Freeman, Harvard Law School environmental and energy law director, told The Washington Post. Indeed, as this summer’s climate events have demonstrated, time is of the essence on climate legislation.
