What is Ozone Depletion Potential?
Ozone Depletion Potential (ODP) is the ratio of ability of a substance to degrade ozone, to that of chlorofluorocarbon-11 (CFC-11).
Ozone Depletion Measurements of Different Products
HCFCs are thought to be between 0.001 and 0.11, i.e. up to 1000 times less degrading than CFC-11, which has a value of 1.0, whilst other substances, such as Pentane, have an ODP of zero., i.e. they do no harm to ozone.
