Senate Bill 372 (SB 372) directs CARB to develop an assistance program to support the adoption of medium- and heavy-duty zero-emission vehicles (ZEVs). This includes financial support, such as incentive and loan programs, and non-financial support, such as web resources, technical assistance, and training. 

CARB worked with stakeholders to determine how we could encourage commercial vehicle owners to use cleaner technology such as zero-emission trucks, and better support them in this process. Input was received from those who have been advocating for cleaner transportation and from medium- and heavy-duty truck owners, who will benefit most from improvements to funding programs and other resources that CARB is developing to support them. 

The feedback received from stakeholders included:

• Replace diesel trucks with zero-emission trucks as soon as possible
• Focus on funding the electrification of small fleets
• Marginalized communities are not receiving outreach and not hearing about funding opportunities
• Workforce development & capacity building is needed
• Fueling infrastructure install costs, land availability, public access, and charging times all pose challenges
• Proposed regulatory deadlines are coming too soon for fleets to install fueling infrastructure in time
• Truck owners need funding for infrastructure
• Truck owners need technical assistance when navigating the transition to zero-emission vehicles
• Truck owners need a streamlined funding application process and timelines

CARB is addressing these concerns through the development of zero-emission vehicle regulations, funding programs that prioritize small truck fleets, collaboration with other State agencies on infrastructure, more compliance pathways for zero-emission regulations, a state-wide technical assistance program, and more.
