Natural Gas Vehicles: A Clean Alternative

Cleaner at the Tail Pipe

The short answer is that yes, natural gas is a cleaner alternative if the only other option is petroleum. With CNG, many key emissions are significantly reduced. According to EPA tests, carbon monoxide emissions are reduced by 90 to 97 percent, carbon dioxide emissions reduced by 25 percent, and nitrogen oxide emissions reduced by 35 to 60 percent.

In summary, the EPA found that there are "fewer toxic and carcinogenic emissions from natural gas vehicles, and virtually no particulate emission."
