California moves to ban sale of diesel vehicles by 2036, require zero-emission trucks by 2042

California approved rules to ban the sale of diesel trucks and buses by 2036 and require large trucking fleets to convert to zero-emission vehicles by 2042.
The new rules follow the state's plan to end the sale of gas-powered cars by 2035.
Trucking and construction groups argue the rules rely on technology that is not yet viable and will hurt their industries.
The rules aim to cut pollution and greenhouse gas emissions from transportation, which produces roughly half of California's emissions.
The rules require school buses, garbage trucks and other medium- and heavy-duty vehicles to transition to zero-emissions within four years.
