What is a carbon footprint?
A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) generated by our actions. The average individual footprint in industrialized nations is significantly higher than the global target required to avoid severe climate impacts.
This calculator uses standardized EPA conversion factors to translate daily actions—like burning natural gas for heat, consuming grid electricity, driving gasoline vehicles, taking commercial flights, and generating municipal waste—into metric tons of CO2 equivalent (CO2e) per year.
