Carbon Dioxide equivalent (CO2e)

A measure used to compare the emissions from various types of greenhouse gas (GHG) based on their global warming potential (GWP).
The CO2 equivalent for a gas is determined by multiplying the metric tons of the gas by the associated GWP, and is expressed in tC02e.
Example: 20 tCO2e can be used to describe the emissions of 20 tonnes of carbon or 1 tonne of methane
