How Plan A Calculates Mobile Combustion Emissions

Using the 'fuel consumption' calculation method, Plan A calculates your stationary combustion emissions by multiplying your fuel consumption (per fuel type) by an emission factor applicable to the given fuel type, timeframe and location (country where the fuel is burnt). The emission factor captures tank-to-wheel emissions - the emissions produced when fuel is consumed upon entering the engine to the point where it is converted into kinetic energy by the vehicle wheel.

This calculation method adheres to the Greenhouse Gas (GHG) Protocol.

Your entries on average fuel consumed (aka vehicle efficiency) are multiplied by the distance travelled and by emission factors applicable to the given fuel type, timeframe and location (country where the fuel is burnt). The emission factor captures tank-to-wheel emissions - the emissions produced when fuel is consumed upon entering the engine to the point where it is converted into kinetic energy by the vehicle wheel.

The inputted distance travelled is multiplied by the emission factors applicable to the selected vehicle and fuel types, timeframe and location (country where the fuel is burnt). The emission factor captures tank-to-wheel emissions - the emissions produced when fuel is consumed upon entering the engine to the point where it is converted into kinetic energy by the vehicle wheel.

The inputted distance travelled is multiplied by the mass of the objects driven, as well as well as emission factors applicable to the given vehicle and fuel types, timeframe and location (country where the fuel is burnt). The emission factor captures tank-to-wheel emissions - the emissions produced when fuel is consumed upon entering the engine to the point where it is converted into kinetic energy by the vehicle wheel.

Bring Your Own Emissions allows you to upload your own pre-calculated emissions to the Plan A platform. For more information, see here.
