How is global warming potential calculated
Web18 jul. 2014 · The global warming potential (GWP) is a measure of how much a given mass of GHG is estimated to contribute to global warming. This is calculated over a specified time period and must be stated whenever a GWP is stated. For example, GWP over 100 years for nitrous oxide is 298. Web10 apr. 2024 · Methane (CH 4) and nitrous oxide (N 2 O) are two important greenhouse gases, which increase the global warming. The global warming potential (GWP) of CH 4 and N 2 O at the 100-year scale is about 28 and 265 times of CO 2, respectively (IPCC 2014).Farmland is an important source of greenhouse gas emission (Tubiello et al. 2015; …
