Neapolitan Express, the first mobile food truck fully-powered by compressed natural gas, is unveiled at City Hall Park in New York, Thursday, Feb. 21, 2013.
NEW YORK -- A pizza purveyor is now running the first food truck in New York City to be run completely on natural gas.
Mayor Michael Bloomberg and Texas oil and gas investor T. Boone Pickens were on hand at City Hall Park Thursday to mark the launch of the Neapolitan Express truck.

Some food trucks have run some of their equipment on natural gas, but they generally also use diesel, gasoline and/or propane.
Natural gas proponents say it's more environmentally friendly, although there is controversy surrounding environmental questions about the natural gas drilling process known as fracking.
Neapolitan Express says its truck will emit 70 percent fewer greenhouse gases than a similar vehicle running off gasoline or diesel fuel.
The truck will be stationed at various spots around the city.
