## Definition

**Carbon Dioxide Equivalent** (CO2e or CO2eq) is a unit of measurement that represents different greenhouse gases in a single unit by converting them into an equivalent quantity of CO2 based on their global warming potential (GWP). \[It allows a [Carbon Footprint](https://chancerylaneproject.org/wp-content/uploads/wp-mfa-exports/glossary-term/carbon-footprint.md) consisting of different GHGs to be expressed as a single number\].
