6.7 Phasing Out of Ozone Depleting Substances in Hong Kong

To help protect the earth's ozone layer, the Ozone Layer Protection Ordinance (OLPO) was enacted in July 1989 giving effect to Hong Kong's international obligations under the 1987 Montreal Protocol and its amendments to control the import and export of ozone depleting substances.

Under the Montreal Protocol as amended in the Copenhagen meeting in November 1992, an accelerated schedule to phase out ozone depleting substances was adopted. Hong Kong has put a programme in place which will achieve the controls and timetable provided for in the Protocol.

Through a quota and licensing system, Hong Kong has made progress in phasing out ozone depleting substances. As from 1 January 1994, halon imports have been banned for local consumption. Starting from 1 January 1995, methyl bromide imports have been restricted to local quarantine and pre-shipment applications only. There are also bans on importing CFCs, carbon tetrachloride, HBFCs, and 1,1,1-trichloroethane for local consumption, all from 1 January 1996. Control of HCFC imports also began on 1 January 1996.
