The U.S. Environmental Protection Agency recently announced the selection of 70 applications to receive a total of around $735 million in funding under the Clean Heavy-Duty Vehicles (CHDV) Grant Program. This funding will go towards supporting the purchase of approximately 2,400 new Class 6 and Class 7 zero-emission school buses and vocational vehicles in 27 states, three Tribes, and one U.S. territory. The replacement vehicles will include battery-electric and a small number of hydrogen fuel cell transit buses, aiming to reduce harmful pollutants and greenhouse gases. The CHDV Grant Program is designed to combat air pollution and reduce emissions by encouraging the deployment of zero-emission heavy-duty vehicles and associated infrastructure. The initiative targets areas that do not meet the National Ambient Air Quality Standards, with over $400 million allocated for projects serving these communities. Additionally, the program aligns with the White House's Justice40 Initiative to ensure environmental benefits flow to disadvantaged communities. Key aspects of the program include sub-programs for school buses and vocational vehicles, with 70% of the funding dedicated to school bus projects and 30% to vocational vehicle projects. Funding will also support the infrastructure necessary for charging, fueling, and maintaining zero-emission vehicles, as well as training for workforce development. Selected projects cover a range of replacement vehicle types such as cargo trucks, emergency vehicles, school buses, shuttle buses, and utility vehicles. By supporting the transition to cleaner vehicles, the CHDV Grant Program aims to improve air quality, community health, and overall environmental sustainability.
