R-22 is often used as an alternative to the highly ozone-depleting CFC-11 and CFC-12, because of its relatively low ozone depletion potential of 0.055,[REF] among the lowest for chlorine-containing haloalkanes.
As an additional environmental concern, R-22 is a powerful greenhouse gas with a global warming potential equal to 1810 (which indicates 1810 times as powerful as carbon dioxide).[4]
