Welcome to the Emissions Calculator. You can use this calculator to estimate emissions for up to five different fuel types.
Enter actual fuel consumption data for each fuel then click "Calculate" to estimate total carbon emissions from a vehicle or fleet of vehicles.
Notes on the Emissions Calculator
Biodiesel and ethanol (* above): 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 of the blend is diesel (for biodiesel blends) and gasoline (for ethanol blends). In our example, it would calculate 200 litres of pure biodiesel emissions, and 800 litres of diesel emissions. Biodiesel feed stock in the calculation is canola; ethanol feedstock is corn. Results will vary with different feedstocks.
Lifecycle Emissions Calculation: Lifecycle emissions are entire fuel cycle, but do not include vehicle assembly and materials. Note that CO2e means “carbon dioxide equivalent”, that is, emissions equivalent to the climate change potential equivalent of CO2 regardless of actual emission type. In the case of motor vehicle emissions, most GHG emissions are in fact CO2.
Disclaimer: These calculator results are estimates, using emission factors and assumptions from Natural Resources Canada’s GHGenius v3.14 model.
