Medium- and Heavy-Duty Zero Emission Vehicle (ZEV) Requirement

Colorado has adopted the California Advanced Clean Trucks requirements specified in Title 13 of the California Code of Regulations, requiring manufacturers to meet California ZEV production and sales requirements. Beginning with model year 2027, manufacturers will be required to sell zero-emission trucks as an increasing percentage of their annual sales for Class 2b through Class 8 vehicles in Colorado. ZEVs include all-electric and fuel cell electric vehicles. For more information, see the Colorado Department of Public Health & Environment Clean Trucking website.
