2. Description of the Prior ArtThe “carbon footprint” refers to the greenhouse gases directly or indirectly produced by human beings in various activities. When the greenhouse gases are discharged into the atmosphere of earth, the greenhouse effect is produced, and then, global warming will be caused by greenhouse effect. Thus, the total weight of greenhouse gases is called as “carbon footprint”. Among various greenhouse gases, carbon dioxide (CO2) occupies the largest proportion in the atmosphere, so that the weight of carbon dioxide is the most common measure stand of carbon footprint, and the so-called carbon footprint can be defined as the amount of carbon dioxide emission directly and indirectly produced during the entire life cycle of an activity or product, wherein the life cycle refers to the raw materials obtained, or produced from natural resources to the final disposal, related to the continuous and interconnected schedules in the product system.
