All about carbon footprint and ways to reduce it
The six greenhouse gases listed in the Kyoto Protocol (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulphur hexafluoride) as well as other types of climate impacts like the vapour trails from aeroplanes are all included in the calculation of a person's carbon footprint.
Carbon footprint is the total amount of these greenhouse gases produced by all human actions. The human race is a continuation of the earth. Whatever humans do, they always do it in or on the planet's ecology. Humans and the ecology of the planet Earth are constantly interacting. Therefore, every human action has the potential to either increase or decrease carbon footprints.
