California Seeks To Ban Sales Of Diesel Big Rigs In A Bold Bid To Cut Pollution

Sep 26, 2022

Saying they had a “moral obligation,” California regulators could soon ban the sale of diesel big rigs by 2040, ending a long reliance on the polluting vehicles that are the backbone of the American economy.

The proposal by staff of the California Air Resources Board would further require that, by 2035, medium- and heavy-duty trucks entering ports and railyards must be zero emission and that state and local government fleets be so by 2027.

The new regulations would likely demand a radical buildup of electric charging infrastructure, placing new stresses on California’s already fragile power grid and force the trucking industry to reshape how it does business. Regulators and activists say any disruption would ultimately be outweighed by lives and money saved.

“Pound for pound, heavy-duty trucks are putting out far more pollution than anything else on the road,” said Will Barrett, national senior director for clean air advocacy with the American Lung Assn. “And that’s really directly contributing to the fact that California has the worst air pollution in the country.”

The proposal follows last month’s vote by the board to end the sale of new gas-powered passenger cars and light trucks by 2035, citing an urgent need to combat human-caused climate change. The combination of measures puts heavy pressure on manufacturers and policymakers to move more swiftly toward emission-free vehicles.

The California Air Resources Board, which must vote on the truck proposal, is expected to consider it Oct. 27.

Many who rely on the trucks for work or commerce are worried the state isn’t ready for such a quick transformation.

“There is no infrastructure to support this,” said Chris Shimoda, vice president of the California Trucking Assn.

Even if California built up the charging infrastructure starting today, he said it’s unlikely that there would be enough to support the 400,000 big rigs traveling up and down the state by the deadline.

There are already 1,900 medium- and heavy-duty zero-emission vehicles operating in California, most of which are transit buses.

“It would be the next significant step in accelerating towards a zero-emission (ZE) transportation system as well as a more equitable future in California,” the proposal said.
