CO2eq
CO2 equivalent (CO2e) is a metric used to compare the warming effects of different greenhouse gases (GHGs) by expressing their emissions as the amount of CO2 that would cause the same total warming over a given time horizon. It allows diverse gases to be represented on a common scale for inventorying, reporting, and policy analysis.
Calculation and units: CO2e is obtained by multiplying the mass of a gas emitted by its global
Typical GWPs and examples: Methane (CH4) has a GWP around 28–34 for 100 years, depending on the
Applications and limitations: CO2e is widely used in greenhouse gas inventories, regulatory reporting, corporate sustainability metrics,
In summary, CO2e provides a practical, standardized way to compare and sum emissions from different greenhouse
