R22, also known as HCFC-22, has been commonly used in air conditioning and refrigeration systems in Australia since the 1990s.

Releases of R22 into the earth’s atmosphere, particularly those from leaks, contribute to the depletion of the earth’s ozone layer and the issues associated with GWP.

Australia, under its Montreal Protocol obligations has ceased the import of HCFC’s in the period since 2016.

The reduction in import quotas has seen a steep rise in the price of HCFC-R22 to around $395.00 per Kg (list price)
