global warming potential

[¦glō·bəl ′wȯrm·iŋ pə‚ten·chəl]
(meteorology)
The ratio of global warming or radiative forcing from 1 kilogram of a greenhouse gas to 1 kilogram of carbon dioxide over 100 years, expressed per mole or per kilogram; it provides a way to calculate the contribution of each greenhouse gas to the annual increase in radiative forcing.

The use of carbon dioxide as a refrigerant is also growing in popularity due to its relatively low global warming potential.
In the past, formulators had to choose between flammable propellants like hydrocarbons and dimethyl ether, which have low global warming potentials (GWPs) but are VOCs, or a nonflammable propellant, like HFC-134a, which is not a VOC but has a higher GWP," said Terrence Hahn, vice president and general manager of Honeywell Fluorine Products.
switched from sending food scraps to the landfill to using a disposer instead, the reduction in global warming potential would be the equivalent of eliminating nearly 2,100 tons of carbon dioxide emissions.
This halocarbon reclamation facility will be state of the art with the latest, most advanced equipment for the reclamation and management of Halons and refrigerants that are either ozone depleters or high in global warming potential.
The new refrigerant, called an HFO, has a global warming potential of just 4 compared to over 1,400 for the current refrigerant, HFC-134a.
These are naturally produced and non toxic with a global warming potential (GWP) of less than 3.
So) the lower the atmospheric lifetime for a particular material, then the lower the global warming potential as well.
The statement added: "Refrigeration and air-conditioning equipment contains Fluorinated Greenhouse Gases, such as HFCs, which have a very massive global warming potential relative to carbon dioxide.
The overall goal of mixtures is to match performance parameters of low global warming refrigerants to those that we are used to without increasing the global warming potential (GWP) of either the fluids themselves or their indirect contribution.
Second Nature Medium Temperature systems--designed to keep refrigerated foods at optimum temperatures--replace R404A, a halogenated fluorocarbon (HFC) and contributor to greenhouse gases, with a 35% aqueous propylene glycol fluid and R407C, a non-halogenated refrigerant with less than half of the global warming potential of traditional HFC refrigerants.
HFO 1234yf has significantly lower global warming potential than the existing R134a standard refrigerant, and SAE sought to test air conditioning equipment components for compatibility issues.
The new design features reduction in key environmental indicators like global warming potential and will reduce the weight of a billion less diapers every three years.
