Glossary

Carbon dioxide is the dominant greenhouse gas in the world. Carbon dioxide is produced by the combustion of carbonaceous fuels, including all fossil fuels. For a given energy source, the amount of CO2 generated depends directly on the amount of fuel and thus the energy converted. Main indicator of the greenhouse effect.

“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.
