What is Carbon Footprint?

Before jumping into the list, first, it is essential to understand carbon footprint. For the uninitiated, carbon footprint is the amount of greenhouse gas released into the atmosphere. It includes but is not limited to carbon dioxide, methane, and nitrous oxide. You measure Carbon footprint in equivalent tons of CO2 (lower is better), typically on an annual basis.
