The Biden administration on Friday announced a regulation designed to turbocharge sales of electric or other zero-emission heavy vehicles, from school buses to cement mixers, as part of its multifront attack on global warming.
The Environmental Protection Agency projects the new rule could mean that 25 percent of new long-haul trucks, the heaviest on the road, and 40 percent of medium-size trucks, like box trucks and landscaping vehicles, could be nonpolluting by 2032. Today, fewer than 2 percent of new heavy trucks sold in the United States fit that bill.
The regulation would apply to more than 100 types of vehicles including tractor-trailers, ambulances, R.V.s, garbage trucks and moving vans.
The rule does not mandate the sales of electric trucks or any other type of zero or low-emission truck. Rather, it increasingly limits the amount of pollution allowed from trucks across a manufacturer’s product line over time, starting in model year 2027. It would be up to the manufacturer to decide how to comply. Options could include using technologies like hybrids or hydrogen fuel cells or sharply increasing the fuel efficiency of the conventional trucks.
