Explanation

A carbon footprint measures the total amount of carbon dioxide (CO2) emissions caused directly or indirectly by an activity, organization, or individual, primarily through fossil fuel combustion. It is not about physical size, tree absorption, or fossil imprints. The term refers to the environmental impact measured in CO2 equivalent emissions.
