Phase I GHG

This page last reviewed March 8, 2013

Background

Truck imageCalifornia Air Resources Board (ARB) staff is now seeking input on adopting a new regulation for greenhouse gas (GHG) emissions from heavy-duty trucks and engines sold in California. Staff’s proposal would establish GHG emission limits on truck and engine manufacturers and would harmonize with the recently adopted U.S. EPA rule for new trucks and engines nationally. Existing heavy-duty vehicle regulations in California include engine criteria emission standards, tractor-trailer GHG requirements to implement SmartWay strategies (i.e., the Heavy-Duty Tractor-Trailer Greenhouse Gas Regulation), and in-use fleet retrofit requirements such as the Truck and Bus Regulation. This new regulation would be the first California regulation to set GHG emission limits for heavy-duty truck and engine manufacturers. In September 2011, the U.S. EPA adopted their new rule for heavy-duty trucks and engines. The U.S. EPA rule has compliance requirements for new compression and spark ignition engines, as well as trucks from Class 2b through Class 8. Compliance requirements begin with model year (MY) 2014 with stringency levels increasing through MY 2018. The rule organizes truck compliance into three groupings, which include a) heavy-duty pickups and vans; b) vocational vehicles; and c) combination tractors. The U.S. EPA rule does not regulate trailers.

Staff plans propose the Phase I GHG standards to the Board in late 2013.
