Natural gas vehicles' green house emissions are far less than the traditional fossil fuel vehicles such as gasoline. Natural gas vehicles produce 20 percent to 40 percent less smog, and 5 percent to 9 percent less greenhouse emissions. The emissions from natural gas vehicles are not such hazardous as gasoline to the environment.
  • Availability of natural gas resources: More than eighty percent  of the natural gas used in vehicles is produced in the United States only. Natural gas deposits are available in a huge amounts. Natural gas has not been used to the same extent as is the case with petroleum.
