Carbon Footprint is a well-known term used to address Green House Gases (GHG) Emission Inventories. GHG includes several compounds such as Carbon Dioxide, Methane and Nitrous Oxide that are reported as Carbon Dioxide Equivalent "CO2e". The impact on the atmosphere of the GHG varies according to the Global Warming Potential (GWP) that is a measure of the amount of heat a GHG traps in the atmosphere up to a specific time horizon, relative to carbon dioxide.
Depending on the scope of the inventory, emissions can include activities directly related to the business (Scope 1), emissions related to electricity consumption (Scope 2) as well as emissions related to activities out of the control of the business (Scope 3). The scope of the inventory has to be carefully tailored to custom fit every business needs in function of the specific objectives and timeline.
