Emissions Calculator


Handling & Use ::
This model provides average reductions of emissions comparing USEPA approved diesel fuel with biodiesel. The results are compiled from engine testing on diesel engines without diesel particulate filters or SCR equipped engines. Results for a particular engine type and model year may vary
Total Fuel Usage:  Do NOT use commas!   (i.e. enter 300000 and not 300,000)
Enter % biodiesel in blend:     For example, for B20, enter 20

Note on CO2 reductions:
Biodiesel provides a lifecycle reduction in greenhouse gas emissions of 76.4% relative to average 2005 petroleum diesel fuel.  This revised analysis by the University of Idaho and the USDA includes the complete direct and indirect greenhouse gas emissions of producing biodiesel.  This latest study updates previous methods used by USEPA in 2010.  Global warming potentials of various greenhouse gases are weighted to present result in CO2 equivalents.
