What is Carbon footprint?

The total greenhouse gas emissions caused by an organisation, product or activity, expressed in carbon dioxide equivalent (tCO₂e).

A corporate carbon footprint is calculated under the Greenhouse Gas Protocol, and a product carbon footprint using a life-cycle approach. Because of regulations such as CBAM, carbon footprint data is becoming a commercial necessity for exporters.
