Global Warming Potential
A measure of how much a given mass of greenhouse gas is estimated to contribute to global warming relative to the same mass of Carbon Dioxide.
|Carbon Dioxide (CO2)||1|
|Nitrous Oxide (N2O)||296|
|Sulphur Hexafluoride (SF6)||22200|
This index approximates the time-integrated warming effect of a unit mass of a given greenhouse gas in today’s atmosphere, relative to that of carbon dioxide.
