Carbon footprint. Conceptual image showing the chemical formula for carbon dioxide (CO2) written as clouds in the sky. Carbon footprints are measured in terms of carbon dioxide. This is the main greenhouse gas that contributes to man-made global warming, also known as anthropogenic global warming (AGW). It is thought that the main increases in carbon dioxide are due to the burning of fossil fuels for energy.
