8.3.2 Global warming potential Greenhouse gases warm the earth by absorbing energy and decreasing the rate at which the energy escapes the atmosphere. These gases differ in their ability to absorb energy, that is, they have various radiative efficiencies. They also differ in their atmospheric resid...
2.3.1Global warming potential Global warming potential(GWP) is an important environmental impact to consider in the evaluation of renewable energy systems. GWP refers to the potential of the system to trap greenhouse gases in the atmosphere, leading toclimate change. Gases which contribute to global...
important greenhouse gases. Here we extend recent work on halocarbons5,6by proposing an index of global warming potential for methane, carbon monoxide, nitrous oxide and CFCs relative to that of carbon dioxide. We find, for example, that methane has, per mole, a global warming potential 3.7 t...
Methods to measure net global warming potential (GWP) and greenhouse gas intensity (GHGI) that account for all sources and sinks of GHG emissions in agroecosystems are still evolving. Sources of GHGs include soil CO2, N2O, and CH4 emissions and CO2 emissions associated with farm operations, N ...
Allgreenhouse gaseshave what is called a Global Warming Potential (GWP). This value is used to compare the abilities of different greenhouse gases to trap heat in the atmosphere. GWPs are based on the heat-absorbing ability of each gas relative to that of carbon dioxide (CO2), as well as...
GHG emissions are measured in one tonne of carbon dioxide equivalent. It is taken as the reference gas against which other greenhouse gases are measured and therefore has a Global Warming Potential of one (1). For example: 1 tonne of Nitrous oxide (N2O) has a GWP of 310, indicating that...

The net exchange of CH4, N2O and CO2 in terms of CO2 equivalents between soils and the atmosphere comprises the net global warming potential (NGWP) of a cropping system (Robertson and Grace, 2004), which can also be expressed on the basis of per unit of yield (greenhouse gas intensity, ...
