Carbon dioxide equivalent

(CO2e)
Emissions of greenhouse gases are typically expressed in a common metric so that their impacts can be directly compared, as some gases are more potent, i.e., have a higher global warming potential than others. The international standard practice is to express greenhouse gases in carbon dioxide equivalents.
