How Plan A Calculates Stationary 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.

* While commonly associated with mobile sources, the concepts of Tank-to-Wheel (TTW) and Well-to-Tank (WTT) emissions are equally applicable to stationary combustion scenarios. TTW emissions in this context refer to the direct emissions resulting from the combustion of fossil fuels (e.g., coal, natural gas, oil) in stationary facilities such as power plants and industrial setups to generate electricity or heat. These emissions are directly tied to the operational phase of the stationary sources.

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

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