Carbon footprint• A carbon footprint is "the total set of greenhouse gases (GHG) emissions caused by an organization, event or product" .• For simplicity of reporting, it is often expressed in terms of the amount of carbon dioxide, or its equivalent of other GHGs, emitted.
•The concept name of the carbon footprintoriginates from ecological footprintdiscussion.• The carbon footprint is a subset of theecological footprint and of the morecomprehensive Life Cycle Assessment(LCA).
•An individual, nation, or organizationscarbon footprint can be measured byundertaking a GHG emissions assessment.•Once the size of a carbon footprint isknown, a strategy can be devised toreduce it,e.g. by technological developments, betterprocess and product management, changedGreen Public or Private Procurement (GPP),Carbon capture, consumption strategies, andothers.
The mitigation of carbon footprintsthrough the development of alternativeprojects, such as solar or wind energy orreforestation, represents one way ofreducing a carbon footprint and is oftenknown as Carbon offsetting.
Ecological footprint•The ecological footprint is a measure of humandemand on the Earths ecosystems.•It compares human demand with planet Earthsecological capacity to regenerate.• It represents the amount of biologicallyproductive land and sea area needed toregenerate the resources a human populationconsumes and to absorb and render harmlessthe corresponding waste.
Life cycle assessmentA Life Cycle Assessment is theinvestigation and evaluation of theenvironmental impacts of a givenproduct or service caused ornecessitated by its existence.
