Sales requirements for zero-emission heavy duty trucks.
On June 25, 2020, the California Air Resources Board (CARB) adopted the final rule for new standards that require the sale of zero-emission heavy-duty trucks (HDTs), starting with the 2024 model year. The Advanced Clean Trucks (ACT) regulation, first of its kind in the world to require manufacturers to sell increasing percentages of zero-emission trucks, is expected to reduce the lifecycle emission of greenhouse gases (GHGs) and eliminate tailpipe emissions of air pollutants. Zero-emission purchase requirements targeting commercial truck fleets operating in California are expected in the next few years.
