Use this Carbon Calculator to estimate Greenhouse Gas (GHG) emissions from using multiple fuels.

Enter actual fuel consumption data for each fuel then click Calculate to estimate total carbon emissions from your fleet.

Total Carbon Emissions:

*For % Biodiesel or Ethanol, enter the percentage biofuel blend. For example, if you used 1000 litres of B20, you would enter 20% biodiesel, 1000 litres. The calculator assumes the remainder is diesel for Biodiesel and gasoline for Ethanol. In our example, it would calculate 200 litres worth of pure biodiesel emissions, and 800 litres worth of diesel emissions.

Also see our simpler, one fuel at a time calculator.

Lifecycle emissions are entire fuel cycle, but do not include vehicle assembly and materials. Light Duty Vehicles.
Biodiesel feed stock in the calculation is Canola, Ethanol feedstock is Corn. Results will vary with different feedstocks.
CO2e means the climate change potential equivalent worth of CO2 (most of which actually is CO2).
