global warming potential

Chemical Engineering

The overall assessment of the effect on the climate by the release of one kilogram of a gas to carbon dioxide, which is used as the reference. A GWP of a so-called greenhouse gas is dependent on its lifetime within the troposphere that surrounds the Earth and the radiative efficiency, which is the amount of infrared radiation that the gas can trap and is dependent on the frequency at which infrared radiation is absorbed. The GWP of carbon dioxide is 1, whereas the GWP of methane is 25. The GWPs (p. 170) of CFC-11 and CFC-13 are 45 and 640, respectively. Their manufacture and use is no longer permitted. See greenhouse effect.

Geology and Earth Sciences

A ranking of the absorptive capacity of the principal greenhouse gases expressed as the atmospheric warming effect of each compared with that of carbon dioxide, which is given a value of 1. The values take account of the wavelengths at which each gas absorbs radiation and its atmospheric residence time, and values are given over a specified number of years. On this scale, the GWP of methane is 56 (20 years), 21 (100 years), and 6.5 (500 years), nitrous oxide is 280 (20 years), 310 (100 years), and 170 (500 years), HFC-23 is 9100 (20 years), 11 700 (100 years), and 9800 (500 years), and sulphur hexafluoride is 16 300 (20 years), 23 900 (100 years), and 34 900 (500 years).
