California’s Air Resources Board (CARB) has passed a new rule that says all commercial trucks and vans sold in the state in 2045 must be zero-emission, in a bid to move the industry away from the dirty and harmful diesel engines that currently power most of these vehicles. It’s the first rule of its kind in the United States, and it follows California’s 2018 decision to mandate that transit agencies purchase all-electric buses starting in 2029, as well as its long-standing Zero Emission Vehicle (ZEV) program for passenger cars and trucks.
Other milestones will need to be hit in the years leading up to that date, too. California regulators are mandating that half of all trucks sold in the state must be zero-emission by 2035. All short-haul drayage vehicles in ports and rail yards must be zero-emission by 2035 as well, and all last-mile delivery trucks and vans must be switched over by 2040. Smaller sales requirements go into effect as early as 2024.
It’s a bold move that should help curb one of the worst-polluting sectors of the transportation industry. Despite only making up 7 percent of vehicles on the road in California, diesel trucks account for 70 percent of the state’s smog-causing pollution and 80 percent of diesel soot emitted, according to CARB.
