I was asked this question in a group here in Texas - Q - How many people could live in veggie oil powered buses like yours? Does veggie oil produce less greenhouse gas than diesel? How do emissions compare to other fuels? A - Definitive answers are surprisingly hard to come by. Here’s what we can say with certainty: WVO has no sulfur in it. Sulfur is a one of the worst pollutants in petrodiesel. WVO is “carbon-neutral” – meaning that the amount of carbon released in its combustion is no greater than the amount of carbon absorbed from the atmosphere by the plant that yielded it in the first place. Petrodiesel, by contrast, releases carbon that was locked up in the earth’s crust for millions of year, and probably should have stayed there. Many studies point to a net reduction in carbon dioxide, a major greenhouse gas, in WVO-burning cars vs. diesel-burning cars. As far as other pollutants, such as particular matter, Nitrous Oxide, etc., there doesn’t seem to be a strong consensus. And it depends on your car, your conversion, and your variety of WVO. But no study we’ve seen says that WVO pollutes significantly more in any category. Here’s the crux: as a biomass fuel that is free of sulfur, emissions are without a doubt less harmful to the environment and less harmful to living things.
