How do biodiesel emissions compare with petrodiesel?
Combusted biodiesel has significantly lower carbon monoxide, unburned hydrocarbon, particulate matter, and hazardous air pollutant emissions than petrodiesel. Exhaust emissions of aromatics and sulfur oxides are essentially eliminated with B100, and biodiesel has significantly lower asthma and cancer-causing emissions than petrodiesel. Furthermore, considering its entire production and use, biodiesel emits 78% less CO2 than petrodiesel, meaning that its contribution to global warming is far less than petrodiesel’s.
