Innovative Clean Transit
CARB’s heavy-duty vehicle legacy programs have been focused on reducing combustion emissions. New heavy-duty zero-emission vehicle programs are complementary to these programs and focus on the long-term goal of reducing emissions in the heavy-duty transportation sector. They are part of California’s holistic plan to address challenging mandates and needs for public health protection, and to meet federal air quality standards and climate protection goals.
