Marking international day for preservation of the ozone layer, Ministry of Natural Resources and Environment said that Vietnam achieved outstanding success in phase out Ozone-depleting Substances such as chlorofluorocarbon (CFC), hydrochlorofluorobon (HCFC) and halon since the country joined in the Montreal protocol in January, 1994.
In the 90s, Vietnam consumed 500 tons of chlofleorocarbon, 4 tons of holon and nearly 400 tons of methylbromide yearly. Until now, the country has eliminated over 200 tons of CFC-12; 3.6 tons of CFC-11 in the textile and garment industry; 5.8 tons of CFC-12 used in vehicle air conditioners; and 40 tons of commercial refrigeration and household equipment CFC-12.
In January, 2010, Ministry of Natural Resource and Environment prohibited import of harmful substances. However, the country can not reduce the demand for HCFC- 22.
Dealing with the problem, Ministry of Natural Resource and Environment said that Vietnam pledged to phase out controlling of ozone depleting substances in general and HCFC in particular until 2030, contributing to protect not only the ozone layer but also human health and ecosystems.
