Contents >> Environment >> Atmosphere >> Ozone depleting substances

The ozone depleting potential of chlorofluorocarbons and hydrochlorofluorocarbons sold in Tasmania decreased from 3,449 in 1998-99 to 1,792 in 2001-02. This decrease is reflected in the figures for each Region. In both years, the total ozone depleting potential of substances sold in the Greater Hobart-Southern Region was higher than in any other region; however, there was a slight increase in the Northern and Mersey-Lyell regions during 2001-02.

Collections of halon for destruction are not registered at a sub-state level. The ozone depleting potential of registered halon collected state-wide increased in 1999-2000 due to the collection of Antarctic halon registered in Tasmania.

(a) This table excludes data on methyl bromide, another ozone depleting substance used in Tasmania for fumigation and agricultural applications. Data on this substance is not available.
(b) The Ozone Depleting Potential (ODP) of a substance reflects the combination of percentage (by weight) of chlorine and bromine atoms and the lifetime of the compound in the atmosphere, multiplied by the metric tonnage of the substance of e.g. 1 tonne of CFC-11 = 1 ODP of CFC-11; 1 tonne of halon 1211 = 3 ODP of halon 1211.
(c) CFCs (Chlorofluorocarbons) and HCFCs (Hydrochlorofluorocarbons) are ozone depleting substances used in refrigeration and air conditioning. Sales of these substances are registered with the Department of Primary Industries, Water and Environment.
(d) Halon is an ozone depleting gas used in yellow fire extinguishers. Halon is collected by the Department of Environment and Heritage and DASCEM for safe disposal at the National Halon Bank.
(e) The 1999-2000, 2000-01 and 2001-02 figures for the ODP of halon collections in Tasmania include the collection of Antarctic halon, which was registered at the Tasmanian depot.
