The concept name of the carbon footprint originates from ecological footprint discussion.[2] The carbon footprint is a subset of the ecological footprint and of the more comprehensive Life Cycle Assessment (LCA).
An individual, nation, or organization's carbon footprint can be measured by undertaking a GHG emissions assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it, e.g. by technological developments, better process and product management, changed Green Public or Private Procurement (GPP), Carbon capture, consumption strategies, and others.
The mitigation of carbon footprints through the development of alternative projects, such as solar or wind energy or reforestation, represents one way of reducing a carbon footprint and is often known as Carbon offsetting.
The term carbon footprint is simply a measure of how much carbon dioxide that you are personally responsible for. The more flights you take every year the higher your footprint; the more you leave heaters and boilers on, the greater is your carbon footprint. The more burgers you consume the greater is your carbon footprint.
But say you drive an electric hybrid. or perhaps you travel to work on public transport that uses hydrogen fuel cells then your carbon footprint will reduce. If you get rid of your old electrical appliances and replace them with energy efficient models you will be reducing your carbon footprint. Likewise if you unplug your TV before turning in you will doing the planet and Mankind a great service since you will be reducing your carbon footprint.
But for all those who say it's a con,or sick joke, I urge you to get out and go to the main centres of research into climate change and
