Companies, individuals, countries, products, services, processes and so on (hereinafter referred to as “entities”) have a certain impact on our climate respectively because they (indirectly) involve GHG producing processes such as transport, land clearance, and the production and consumption of fuels, food, manufactured goods, materials, wood, roads, buildings, and services.
These (indirect) emissions can be quantified by the carbon footprint, which measures the total amount of CO2 (and optionally other GHGs, expressed as CO2 equivalents) emitted by an entity through these GHG producing processes. By using recognised methods, such as “Bilan Carbone,” GHG protocol, ISO 14064, PEF, OEF, etc. the actual footprint can be visualised. By looking at the separate emissions of different components (e.g. emissions from energy use, material use, transport, etc.), the carbon footprint study exposes the biggest CO2 emissions sources.
