The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. It is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO 2 ). GWP measures a greenhouse gas's ability to trap heat for 100 years. Carbon dioxide has a global warming potential of one, and other greenhouse gases are measured against it. The gases with the highest GWP are known as greenhouse gases. Hydrofluorocarbons (HFCs) have GWPs ranging from a few hundred to several thousand depending on the specific HFC compound, with the highest GWP for HFCs currently around 14,800.
