NGV Environmental Benefits NGV Environmental Benefits Natural
gas is one of the cleanest burning alternative transportation
fuels available today. Long recognized as an excellent fuel when
used to generate electricity, heat homes, and fuel industrial
facilities, natural gas is emerging as a leader in the
alternative fuels marketplace. Using natural gas as vehicle fuel
helps the environment by positively affecting: - Air Quality -
More Benefits In addition, natural gas does not contaminate
lakes, rivers, or groundwater as petroleum fuels do because it
quickly dissipates into the atmosphere if a leak or spill
occurs. Commercially available medium and heavy-duty natural gas
engines have demonstrated over 90% reduction in particulate
matter and more than 50 percent reduction in nitrogen oxides
(NOx) relative to commercial diesel engines. Natural gas engines
also produce less greenhouse gases (CO2) that contribute to
global warming. See the Alternative Fuels and Advanced Vehicles
Data Center (AFDC) for more inform
