As a Carbon footprint consultant in Agile Advisors, the quantity of greenhouse gases you produce during your lifetime, such as carbon dioxide, methane, nitrous oxide, and fluorinated gases, is your "carbon footprint." According to the Deep Decarbonization Pathways Project, by 2050, each person on Earth will need an average annual carbon footprint of 1.87 tons to keep the global temperature rise to 2˚C or less. The average carbon footprint per person in the United States is currently 18.3 tons. China has 8.2 tons of carbon emissions per person in comparison. To reach 1.87 tons, we still have a way to go. You may calculate how much money and carbon you will save by implementing some of these measures using the EPA's carbon footprint calculator. Eating predominantly fruits, vegetables, grains, and legumes is required.
