Global Warming Potential (GWP)

GWP, is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period  (usually 100 years), relative to the same amount of carbon dioxide (CO2). It is a way to compare the "warming power" of different gases. CO2 has a GWP of 1, while other gases like methane have much higher GWPs, meaning they trap significantly more heat than CO2 over the same timeframe.
