Advanced Clean Cars II

Adopted rule

Administrative Order No. DEQ-23-2022 
Filed and effective: Dec. 19, 2022
See Oregon Bulletin, January 2023

Rulemaking contact: Rachel Sakata, 503-863-4271

This rulemaking is central to DEQ’s efforts to reduce air pollution and transportation-related greenhouse gas emissions. Oregon currently implements a Low Emission Vehicle/Zero Emission Vehicle program that requires auto manufacturers to deliver to Oregon a certain percentage of zero emission passenger cars, SUVs, and light-duty trucks through the 2025 model year. This Advanced Clean Cars II rulemaking continues the existing program and applies to the 2026-2035 model year. It will require auto manufacturers to deliver 100% new zero emission battery electric and plug-in hybrid electric vehicles by 2035. The rules also include updates to the program to ensure new gasoline and diesel vehicles sold through 2024 have the cleanest emissions possible.

DEQ convened an advisory committee to review the technical issues and fiscal impacts related to the proposed rules. In convening this committee, DEQ has appointed members that reflect the range of entities that are both directly and indirectly affected by proposed changes to the rules.
