Your individual emissions - carbon footprint - arise from the energy you use for electricity and travel, as well as the energy required to produce your food, products for your home and everything else you buy, whether it is made in the country you live in or elsewhere in the world.
Carbon dioxide equivalent or CO2e is a term for describing different greenhouse gases in a common unit. For any quantity and type of greenhouse gas, CO2e signifies the amount of CO2 which would have the equivalent global warming impact (GWP). We convert all the different greenhouse gases into an equivalent impact from carbon dioxide, the main greenhouse gas. Your footprint in this calculatur is in carbon dioxide equivalent (CO2e).
