Ozone depleting substances
Certain chemicals (such as chlorofluorocarbons, hydro- -chlorofluorocarbons and halons) are recognized as ozone-depleting
substances (ODS) because they breakdown in the stratosphere and release
chlorine or bromine, which destroy the stratospheric ozone layer. Most
ODS are also
greenhouse gases.
Ozone depleting substances controlled by Montreal Protocol include: CFC's , Halon , Carbon Tetrachloride , Methyl Chloroform , Hydrobromofluorocarbons , Hydrochlorofluorocarbons , Methyl Bromide , Bromochloromethane
There are other ozone depleting substances, but their ozone depleting effects are very small in comparison to these controlled substances.
The Commonwealth Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 controls the manufacture, import and export of these ozone depleting substances in Australia.
All bulk imports of these substances (except HCFCs and methyl bromide) are banned into Australia. See Legislation and Regulations: Ozone and Synthetic Greenhouse Gases.
