For instance, replacing one diesel-powered garbage truck with a natural gas-powered version of the same truck has the same benefit in reducing emissions as taking 325 cars off the road!
NGVs can reduce greenhouse gas emissions by 20 - 29% compared with diesel and gasoline fueled vehicles, respectively. And blending existing natural gas with renewable natural gas -- biomethane -- can reduce NGV emissions even more. Renewable natural gas reduces carbon emissions by almost 90% when compared with gasoline and diesel fuel.
Driving an NGV makes you feel good, because you know with every mile you're doing something to help the environment. Go Natural Gas!
