CARBON FOOTPRINT set of greenhouse gas emissions produced, directly or indirectly, by individuals, organizations, products, events or geographic regions. It is a value that allows to verify the ecological or polluting behaviors of the environment, and serves as a useful management tool. The usual way of calculating GHG emissions is done by applying standardized emission factors. The carbon footprint is measured in tons of CO2 equivalent (tCO2e), and is determined by multiplying the number of activities by emission factors.
