Electric Vehicle Charging


Two public, Level II electric vehicle (EV) charging stations are available at O'Hare. The stations are located on the first level (hourly parking) of the O'Hare short-term parking garage (the Main Parking Garage - Lot A​) adjacent to the entrance to/from the Bus/Shuttle Center. Both stations are available for public use.

The Level II EV chargers are 240-volt, 7.2-kilowatt stations, capable of fully charging an EV in approximately three to eight hours.


Payment is accepted via major credit and debit cards.

The Benefits Of EV Charging Stations

The installations of the EV charging stations supports the City of Chicago's goal to reduce Chicago's greenhouse gas emissions to 25 percent below 1990 levels by 2020, as outlined in the Chicago Climate Action Plan.

Green Fleet Vehicles

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

  • Over 60 hybrid SUVs, buses and pickups
  • 10 compressed natural gas (CNG) trucks and vans
  • Over 260 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)
  • O'Hare operates 55 diesel-powered 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 significantly reduce engine emission levels.

Designated Hybrid Vehicle Parking

The CDA provides preferred parking for hybrid vehicles at O'Hare. In most lots premier parking spaces are available for Hybrid Vehicles. Look for available spots with Hybrid Vehicle Only signs. There are over 60 designated spaces, including 32 in the O’Hare Main Parking Garage as well as in surface parking lots.

Green Taxis

The CDA provides compressed natural gas (CNG) taxi cabs with preferential access to the terminals, encouraging the use of CNG taxi cabs instead of traditionally-fueled vehicles. The CDA's program complements the City of Chicago's Green Taxi Incremental Cost Allowance Program ("Green Taxi Program") launched in April 2011 by the Department of Business Affairs and Consumer Protection (BACP). The CDA's program also supports the City's goal to achieve the greenhouse gas emissions reduction goals outlined in the Chicago Climate Action Plan​.

Approximately 30 CNG cabs are used on a daily basis at O'Hare, making more than 2,500 trips per month.

The CDA is also planning to operate a fueling station that will supply multiple alternative fuels to commercial and private vehicles at and around O'Hare. The alternative fueling station will be located near the intersection of Mannheim and Higgins Rd. and will aid in fueling the increasing fleet of CNG taxi cabs serving O'Hare.


The CDA has also followed the BACP's initiative to educate taxi drivers about "EcoDriving" practices to reduce emissions and save drivers up to $2,200 per year in fuel costs. EcoDriving signs and brochures are posted around the airport to provide insight on idling, weight, air conditioning use, cruise control, proper tire inflation, and other topics.

Cab Drivers

To be eligible for short trip lane access, CNG cabs need to display the official City of Chicago "Green Taxi Chicago Compressed Natural Gas Vehicle" sticker, which can be obtained at the Public Vehicle Inspection Facility at 2420 West Pershing Road.
