What is a carbon footprint?
In theory, a carbon footprint is a measure of the entire green house gas emission of a particular entity (be it a corporation, and organization or an individual). Data such as this would take into account things such as transportation, production, services and others. Most commonly, carbon dioxide and methane alone are taken into account for the sake of simplicity. Once an entity’s carbon footprint has been ascertained, steps may be taken to reduce its size, or to offset it in some way.
