In a press launch on Friday, CARB famous that the transportation sector contributes 40 % of the state’s greenhouse gasoline emissions, and 80 to 90 % of the state’s smog-creating pollution. “Full implementation of the regulation adopted today is expected to reduce greenhouse gas emissions by 19 million metric tons from 2020 to 2050—the equivalent of taking 4 million cars off the road,” CARB wrote.

Battery-electric and gasoline cell buses are two potential avenues for funding, CARB famous.
