Clean Fleet Vehicle & Technology Grant Program

The Clean Fleet Vehicle and Technology Program is administered by the Clean Fleet Enterprise, an initiative of the Colorado Department of Public Health and Environment (CDPHE). This program is designed to support the transition of vehicle fleets to low- and zero-emission alternatives across the state. As part of Colorado’s broader commitment to reducing greenhouse gas emissions and protecting public health, the program offers competitive funding for the acquisition of new vehicles, vehicle conversions, and clean fleet technologies. Applicants must participate in a statewide competitive process in which they provide detailed background information on their current fleet makeup, their preparedness for transitioning to cleaner alternatives, and the financial details for the vehicles or technologies they plan to acquire. A successful application will demonstrate a strong understanding of the program’s requirements, the capacity to manage a long-term fleet transition, and a commitment to integrating electric, fuel cell, or methane-powered vehicles into daily operations. The program offers multiple tiers of base incentives depending on the type and weight class of the vehicle or technology. For instance, battery electric, plug-in hybrid electric, and fuel cell electric vehicles in Class 3 through Class 8 can receive between $30,000 and $275,000 per vehicle. Compressed Natural Gas vehicles and vehicle conversions have their own respective incentive schedules, with conversion incentives ranging from $75,000 to $155,000 depending on the weight class. Clean fleet technology incentives are capped at $55,000 per vehicle. Additional enhanced incentives are available for businesses registered in Colorado, vehicles domiciled in disproportionately impacted communities, and fleets scrapping old vehicles, which can receive up to an additional 10% per vehicle. The program closed its second round of applications on June 21, 2024, with notifications of award expected by October 2024. The Clean Fleet Enterprise has indicated its intention to reopen the program in Fall 2025. Until the next cycle opens, stakeholders are encouraged to review related resources, including application templates, vehicle depreciation documents, and reporting instructions, which are made available on the program’s official web portal. Eligibility is broadly defined and includes organizations operating vehicle fleets within Colorado. Enhanced incentive eligibility requires supplemental documentation such as proof of Colorado business registration or domicile within disproportionately impacted communities. Application categories are segmented by funding type, and applicants must complete separate applications for new vehicle purchases, vehicle conversions, and clean fleet technology implementations.

Language assistance is also available upon request by emailing cdphe_apcd_outreach@state.co.us with the subject line indicating the request for language assistance.
