With more than 700,000 takeoffs and landings a year, Dallas/Ft. Worth International Airport (DFW) is the third busiest airport in the world.

Covering 29 square miles, DFW is a mini-city, with more than 500 service vehicles, most of which operate on compressed natural gas. Two onsite CNG refueling station—one built in 2000, the other in 2010---make it easy for vehicles like airfield sweepers to stop in and fill up. DFW’s CNG usage replaces about 2 million gallons of gasoline and diesel annually, keeping their shuttle buses and other vehicles up and running cleanly.  Employees also use hybrids to travel throughout the airport - all to make the blue Texas skies even bluer.
