Background
In view of the importance of the ozone layer to the global ecological environment, the international community signed the Vienna Convention for the Protection of the Ozone Layer under the convening of the United Nations Environment Programme (UNEP) in 1985. The countries that have signed the convention are required to take action to reverse the trend that the hole in the ozone layer expands year by year. In 1987, the "Montreal Protocol" was enacted to implement control actions to reduce ozone-depleting substances. Taiwan government has followed the Montreal Protocol to phase down the Ozone Depleting Substances, avoid trade barriers and protect the earth.
The mode of Taiwan government complies with the norms of the Montreal Protocol
Adhering to the Montreal Protocol, Taiwan government has reduced the consumption of Halon to zero since 1994 and reduced the consumption of Chlorofluorocarbons (CFCs) to zero since 1996. At the same time, the Hydrochlorofluorocarbons (HCFCs) consumption baseline was counted and set at 638.156 ODP metric tons, and gradually reduced it to 0.5% of the HCFCs consumption baseline (3.191 ODP metric tons) from 2020. Moreover, HCFCs is limited to the maintenance of refrigerating and air-conditioning equipment in use.
Taiwan government has phased out most of Ozone Depleting Substances (ODS) since 2006. Moreover, there are no production of ODSs but 10% of HCFCs consumption, which will be reduced to zero in 2030. And methyl bromide is allowed only for Quarantine and Pre-shipment (QPS) use. The importing permission for ODS is controlled through rigorous reviewing by the Taiwan MOENV.
Regulations related to ozone layer protection
The Taiwan government has adopted the Air Pollution Control Act
as the primary law to control ozone-depleting substances (ODS) in compliance with
the Montreal Protocol. Under this Act, the
Regulations for Management of Montreal Protocol Controlled Substances
were established to regulate ODS; these regulations were revised and promulgated on
February 15, 2019. Additionally, the
Regulations for Management of Methyl Bromide, which control methyl
bromide, were revised and promulgated on February 18, 2019. Furthermore, the
Management Regulations for Hydrochlorofluorocarbons, aimed at
controlling HCFCs, were revised and promulgated on October 13, 2025.
