A measure of the total greenhouse gas (GHG) emissions caused by a corporation, categorized into 3 groups. Scope 1 covers direct emissions from owned or controlled sources. Scope 2 covers indirect emissions from the generation of purchased energy sources. Scope 3 includes emissions outside the boundaries of operational control of a firm, either downstream, generated by product use by the customer, or upstream, generated by a firm’s supply chain.

In the context of the fight against climate change, it has become increasingly important for a large number of organisations to report the so-called carbon footprint. Simply put, the carbon footprint is a quantitative measure of carbon emission or CO2 emissions by a given institution/corporation as a function of the activities.
