San Diego Regional Medium- and Heavy-Duty Zero Emission Vehicle Blueprint Final Report

Transportation is the leading cause of greenhouse gas emissions in the San Diego region, with trucks and buses disproportionately contributing to local air pollution. This project will lead to many anticipated benefits, including reducing air pollution and emissions and improving the quality of life for those living in communities adjacent to freight and transit. Additionally, it will help meet state goals for transitioning medium- and heavy-duty trucks and buses to zero-emission vehicles (ZEV). This document serves as the Final Report by the San Diego Association of Governments (SANDAG) pursuant to its Agreement ARV-21-028 with the California Energy Commission under solicitation GFO-20-601 for “Blueprints for Medium- and Heavy Duty Zero Emission Vehicle Infrastructure.”

The project consists of three primary reports that inform the final San Diego Regional Medium-Duty and Heavy-Duty Zero Emission Vehicle Blueprint: MD/HD ZEV Needs Assessment Report, MD/HD ZEV Technology and Siting Criteria, and a Near- and Long-Term Implementation Strategies. An accompanying outreach and engagement plan was created for the project to ensure that the team provided regular updates and presentations on project deliverables to key stakeholders and community members.

The blueprint project provided SANDAG and its regional partners with a deeper understanding of the region’s existing and future medium- and heavy-duty ZEV landscape and established qualitative and quantitative goals and objectives to accelerate the transition to medium- and heavy-duty ZEV trucks and buses. Through outreach and research, the team identified near- and long-term pilot projects, programs, and policy actions that SANDAG and regional stakeholders can take to address barriers to adoption and equity concerns. The blueprint will serve as an important guide for the San Diego Region as it takes the next steps in transitioning to ZEV trucks and buses.
