Emissions Calculator


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.

Fuel Type
(Tonnes CO2e)
Gasoline litres
Diesel litres
% Biodiesel litres
% Ethanol* litres
Natural Gas kg
Propane litres
Total Carbon Emissions:

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.

E3 Fleet Partners

The E3 Fleet program reflects the commitment and expertise of many people, including some of the country’s most innovative fleet managers. All have a common passion – to see Canada’s fleets take a cleaner, green road to the future.

The Fraser Basin Council launched E3 Fleet in 2006 in cooperation with Climate Change Central (Alberta) and Fleet Challenge. Since October 2016, the program has been managed by Fleet Challenge Inc.

The E3 Fleet Charter members were also pivotal to its success: Auto-Gas Propane, BC Hydro, BC Ministry of Environment, City of Coquitlam, Corporation of Delta, Enbridge, City of Hamilton, Hydro One, City of Kelowna, Township of Langley, District of Maple Ridge, City of North Vancouver, Novex Couriers, City of Prince George, District of Saanich, University of BC and Municipality of Whistler. We’ve enjoyed the journey so far, and it’s only just begun. Join us!
