11–2 The U. S. accounted for 23.0% of the World’s carbon emissions in 1990 and 23.9% in 2001. Nearly half (48%) of the U.S. carbon emissions are from oil use.

Global Warming Potentials (GWP) were developed to allow comparison of the ability of each greenhouse gas to trap heat in the atmosphere relative to carbon dioxide. Extensive research has been performed and it has been discovered that the effects of various gases on global warming are too complex to be precisely summarized by a single number. Further understanding of the subject also causes frequent changes to estimates. Despite that, the scientific community has developed approximations, which are shown below. Most analysts use the 100-year time horizon.
