If you need to estimate total emissions from multiple types of fuel greenfleetsbc.com offers another calculator that does just that!

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).

Disclaimer: Carbon Calculator results are estimates, using emission factors and assumptions from Natural Resources Canada’s GHGenius v3.14 model.
