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 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.
