Fairfax County continually seeks opportunities to green the county fleet, reduce fossil fuel consumption and use alternative fuel vehicles that emit fewer greenhouse gas emissions and harmful pollutants.
The Department of Vehicle Services (DVS) is responsible for providing a comprehensive fleet management program that incorporates environmental stewardship and sustainability. See the chart below for a breakdown of the county’s vehicle fleet.
The Department of Transportation (DOT) is committed to sustainability and green innovation by launching a battery-electric bus pilot program and transitioning its support vehicles to electric and hybrid versions. Electric buses have fewer moving parts, require less maintenance and lower fuel costs when fully charged, and are quieter than traditional diesel or gasoline powered buses.
The county remains committed to transitioning its fleet to EVs or hybrid vehicles as aggressively as possible. However, this transition is influenced by several factors, including the number of vehicles eligible for replacement each year, the availability of EV or hybrid models for specific vehicle needs, and vendor supply limitations due to demand and supply chain issues.

Current challenges to fleet transition include:
Limited electric alternatives for specialized county needs, such as public safety vehicles, large vans, and heavy-duty equipment.
High capital costs for vehicle purchases and the development of charging infrastructure.
Charging infrastructure must account for fleet emergency operations, ensuring resiliency and reliability during power outages and other emergency events.
