USA - Amendments to On-Road Motorcycle Emission Standards and Test Procedures and Adoption of New On-Board Diagnostics and Zero-Emission Motorcycle Requirement

​Proposed rule - The  California  Air  Resources  Board  (CARB) Proposed  Amendments to On-Road Motorcycle (ONMC) Emissions Standards and Test Procedures and adoption of new provisions relating to ONMCs under Division 3, Chapter 1, Article 2 (Approval of Motor Vehicle Pollution Control Devices) under Title 13, California Code of Regulations(collectively "Proposal") will significantly increase the prevalence of zero-emission motorcycles (ZEMs) in California while also reducing emissions from remaining motorcycles that are powered by internal combustion engines (ICE) by greatly harmonizing with more stringent European Union 5 (Euro 5) exhaust emissions standards, proposing more stringent evaporative emissions standards, and adopting additional on-board diagnostic (OBD) requirements beyond Euro 5. The Proposal will drive the sales of ZEMs to 50% in California by the 2035 model year, thereby reducing greenhouse gas (GHG) and smog forming emissions, while also reducing smog-forming emissions from newer ICE motorcycles.

CARB will conduct a public hearing on January 25, 2024 at 9 am Pacific Time to consider approving for adoption the proposed amendments to the On-Road Motorcycle (ONMC) emission standards and test procedures and adoption of new provisions relating to ONMCs under Division 3, Chapter 1, Article 2 (Approval of Motor Vehicle Pollution Control Devices) under Title 13, California Code of Regulations (collectively "Proposed Regulatory Action").

This public meeting may continue at 8:30 am Pacific Time, on January 26, 2024. Please consult the public agenda, which will be posted at https://ww2.arb.ca.gov/rulemaking/2024/on-roadmotorcyclesregulation ten days before the January 25, 2024, Board Meeting, for important details, including, but not limited to, the day on which this item will be considered, how to participate via Zoom, and any appropriate direction regarding a possible remote-only Board Meeting if needed.
