Carbon dioxide equivalent is a measurement that represents the amount of greenhouse gases emitted into the atmosphere. As a result, it is a vital unit of measurement used to track global emissions as part of global efforts to combat climate change. Several synonyms can be used interchangeably to describe this metric, including global warming potential, GWP, and CO2e. Global warming potential takes into account that greenhouse gases such as methane and nitrous oxide have a higher warming potential than CO2. GWP is similarly used in assessing the impact of greenhouse gases on the climate. CO2e, on the other hand, represents the total impact of all greenhouse gases in terms of CO2 emissions.
