The California Air Resources Board (CARB) outlined a proposal of Advanced Clean Truck regulations that would divide truck segments into three classes and help provide clear zero-emission vehicle sale goals in California to meet climate-change targets.

A recent workshop held by CARB proposed dividing trucks into three vehicle groups, with each needing to achieve a certain percentage of EV sales requirements.

According to CARB, this includes:

• Class 2B-3 (8,501- to 14,000-pound GVWR).

• Class 4-8 vocational (14,001-pound GVWR or greater).

• Class 7-8 tractor (26,001-pound GVWR or greater).  

Class 2B-3, which excludes pickups until model-year 2027, would need to reach zero-emission vehicle sales of 3% by 2024 and 15% by 2030. For Class 4-8 vocational, sales percentages would need to be 7% by 2024, but jumps to 50% by 2030. Finally, Class 7-8 tractors wouldn't need to reach any goals until 2027 at 9% and later 15% in 2030.  

This was proposed to help achieve California carbon neutrality by 2045; and maximize criteria emission reductions to meet air quality goals and protect communities, according to CARB. California aims to achieve 1990 greenhouse gas levels by 2020, and 40% below 1990 levels in 2030.

The proposal said an increasing percentage of chassis/vehicle sales in California must be zero-emission from 2024-2030, and also proposed zero-emission powertrain certification be required starting in 2024.

More hearings of the Advanced Clean Truck regulations will be held before the proposal is set, one in December and another sometime in 2020.
