A Carbon Footprint is the amount of carbon dioxide an organization, person, etc. produces.
Carbon dioxide gases can be released in many ways, such as transport, land clearance, and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, and services.
Once the size of a carbon footprint is known, a plan can be formulated to reduce it using methods such as technological developments, better process and product management, consumption strategies, and alternative projects, such as carbon offsetting, which includes solar or wind energy or reforestation.
Carbon footprints are affected by size of a population and their economic output. Individuals and businesses look at these main factors when trying to decrease their carbon footprint. Researchers advise the most useful way to reduce a carbon footprint is to cut the amount of energy required for production or to decrease the dependence on carbon producing fuels.
