Green Fleet Vehicles


To reduce vehicle emissions, the CDA operates alternatively-fueled and hybrid fleet vehicles at O'Hare. The fleet includes:

  • more than 70 hybrid SUVs, buses and pickups
  • 3 compressed natural gas (CNG) vans
  • an all-electric Nissan LEAF
  • more than 100 flex-fuel sedans, pickup trucks, police vehicles and SUVs powered by E85 ethanol (a blend of fuel containing 85 percent ethanol and 15 percent unleaded gasoline)​


Designated Hybrid Vehicle Parking

In addition to electric vehicle charging stations, the CDA provides preferred parking for hybrid vehicles at O'Hare. There are over 60 designated spaces, including 32 in the O’Hare Main Parking Garage as well as in surface parking lots B, C, D and E. This practice encourages employees and the public to operate low-emission hybrid vehicles around the airport instead of conventionally-fueled vehicles.


Snow Removal

During snow events, O'Hare operates four diesel-powered spreader vehicles with the latest engine technology to reduce nitrogen oxide emissions. In compliance with the U.S. Environmental Protection Agency's mandate, these vehicles use diesel particulate filters and selective catalytic reduction applications to reduce engine emission levels by 98 percent of what they were in 1999.
