How does Biodiesel emissions compare with petroleum diesel?
Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the Clean Air Act. The use of Biodiesel in a conventional diesel engine results in the reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to emissions from diesel fuel. In addition, the exhaust emissions of sulfur oxides and sulfates (major components of acid rain) from Biodiesel are nearly eliminated compared to diesel.
