Global Warming Potential (GWP)

Global Warming Potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over time. It allows us to compare different gases based on their impact on global warming. GWP is expressed as a multiple of the heat-trapping ability of an equivalent amount of carbon dioxide (CO2), which serves as the reference. The GWP of a gas depends on its ability to trap heat, how long it stays in the atmosphere, and the timeframe considered.
