September 30, 2024: Advanced Clean Fleets Regulation Truck Regulation Implementation Group (TRIG) – Border Meeting #4.
Registration is now open for the third Border Meeting of the Truck Regulation Implementation Group (TRIG). The Advanced Clean Fleets (ACF) regulation was adopted by CARB at the April 28, 2023, Board Hearing, and was effective on October 1, 2023. The ACF regulation complements CARBs recently adopted Advanced Clean Trucks regulation and will help advance the introduction of zero-emission technologies into California’s truck and bus fleets requiring fleets to move to the cleanest available technology through requirements to both phase-in the use of ZEVs for targeted fleets and a 100 percent medium and heavy-duty zero-emission vehicle sales requirement in California, starting in the 2036 model year. The purpose of the Border TRIG workgroup is to collaborate with border communities and provide guidance and information to meet regulatory requirements to border fleets.

Zero Emission Vehicles (ZEVs) and the Importance of Cleaner Options in the California-Baja California Border Region
Communities around California’s southern border experience substantial air quality impacts relative to the rest of the state, much of which is caused by emissions generated by vehicles traveling across the border. The gap in emissions regulations between the United States and Mexico poses challenges for improving air quality and transitioning to zero emissions alternatives. However, collaborations between agencies in California and Baja California are making progress towards closing this gap and securing clean air for communities on both sides of the border.

Updates to the California-Baja California Border Master Plan
The California-Baja California Border Master Plan (Plan) helps coordinate the border region policy efforts of the California Department of Transportation (Caltrans), the State of Baja California Secretariat of Infrastructure, Urban Development, and Territorial Reorganization (SIDURT), and the San Diego Association of Governments (SANDAG) Service Bureau. The goals of the Plan are to improve the capacity and operations of the existing infrastructure to decrease traffic congestion, facilitate international trade, reduce environmental impacts, and improve overall quality of life for residents in the border region. The Plan is updated every five years (previously in 2021) in close coordination with CARB and other sister agencies. There is a meeting planned for summer 2024 to discuss the Plan further as part of the SANDAG Border Committee process.
