GHG Emissions are primarily measured in what unit?

Greenhouse Gas (GHG) emissions are primarily measured in CO2 equivalent to provide a standardized way to compare the impact of different gases on global warming. Different greenhouse gases have varying degrees of heat-trapping ability, commonly referred to as their Global Warming Potential (GWP). By converting these various gases into CO2 equivalent, one can assess their overall contribution to climate change in a uniform manner.

This unit of measurement enables businesses, governments, and researchers to evaluate and communicate emissions more effectively. It simplifies reporting and target-setting, allowing for clearer comparisons and progress tracking toward emissions reduction goals. Other units listed, such as cubic meters or kilowatt-hours, don't directly correspond to the impact of emissions, and gallons of fuel measure volume rather than greenhouse gas output. This makes CO2 equivalent the clear and standard choice for GHG emissions measurement.
