DFW International Airport has been a long-time user of alternative fuel and advanced technology vehicles. Since adopting its first natural gas vehicles in 1994, the airport currently has over 350
alternative fuel vehicles (AFVs) in its fleet,
including hybrids and natural gas vehicles.
The majority of the airport's shuttle and transit
service burns natural gas. In 2008, DFW
Airport applied for over $500,000 in 
US Department of Energy Clean Cities Recovery Act funding to purchase 28 new CNG-powered shuttle buses. In 2016 alone, DFW Airport reduced over 3 million gallons of petroleum.
