Carbon dioxide equivalent (CO₂e)
Carbon dioxide equivalent (CO₂e) is a unit of measurement used to quantify the climate effects of various greenhouse gases based on their Global Warming Potential (GWP). It provides a standard scale for comparing the warming potential of different gases to that of carbon dioxide (CO₂). CO₂e is more accurate than CO₂ alone in greenhouse gas accounting because it accounts for the GWPs of all gases that contribute to warming. For example, methane has a GWP of 28 CO₂e, which traps 28 times more heat than CO₂ over 100 years.
