What is the co2 emission for bio diesel compare to ordinary diesel fuel?
How is this calculated and why is bio diesel so popular?
CO2 emissions are very similar to emissions from petrodiesel. The difference is, this is carbon that’s extracted from something that was alive recently, generally a plant (it is possible to make biodiesel from animal fat, but that is not done). Plants absorb CO2 from the air, so when you burn biodiesel you are re-releasing CO2 that was in the air during the plant’s life. The long term effects on CO2 are very different from petrodiesel, which releases CO2 that was in the atmosphere millions of years ago.
