What is CO2 equivalent and how does it measure your carbon footprint?
A carbon footprint measures the amount of greenhouse gases (primarily carbon dioxide) released into the atmosphere as a result of day-to-day human activities.
Your carbon footprint is measured in kilograms of carbon dioxide equivalent (CO2e). It is a way of combining multiple greenhouse gases (including carbon dioxide, methane, and nitrous oxide, among others) into one, easy-to-understand unit.
For example, one ton of methane emissions is equivalent to about 29.8 tons of CO2e, because methane has a much stronger warming effect than CO2.
