The use of natural gas-powered vans and shuttles is increasing in U.S. airports. Current applications are available for almost all models of domestic light- and medium-duty vans and shuttles, and many U.S. airports have begun using compressed natural gas (CNG) for their fleets, including the:
- Dallas-Fort Worth (DFW) International Airport – In a move to phase out gasoline-powered cars that produce harmful emissions, DFW allows customers to use CNG taxis as a cleaner alternative to meet their shuttle needs. Almost 95% of DFW’s airport vehicles are CNG-powered.
- Houston Airport Shuttle – An extended agreement to manage and operate parking and shuttle services at George Bush Intercontinental and William P. Hobby airports will include commitments to assist the Houston Airport System (HAS) in "going green" by converting its entire fleet of shuttle buses to CNG. The Houston Airport System is one of the largest airport systems in the world, serving nearly 50 million passengers annually.
- Mineta-San José International Airport – Mineta San José International Airport increased its commitment to cleaner air by arranging up to $1.3 million in new funding for two projects that will enhance the airport's publicly accessible CNG fueling station and provide additional incentives to assist taxi and shuttle van owners to convert vehicles to CNG. Since 2003, the airport has been able to eliminate the use of more than 1.3 million gallons of diesel fuel through the conversion of its own fleet to CNG. This has saved more than $3 million in fuel costs and reduced annual vehicle exhaust emissions by more than 70 tons.
- Seattle-Tacoma International Airport – Sea-Tac has adopted the slogan, "Doing our share for cleaner air naturally," to showcase its shift to CNG. The airport's current fleet has 60 CNG vehicles, including 16 buses and 41 light-duty vehicles. In addition, the Seattle-Tacoma International Taxi Association fleet operates its entire 166 CNG-powered Crown Victoria sedans out of the same area.
