(VEN) - Since participating in the Montreal Protocol, Vietnam has achieved remarkable success in gradually limiting the use of substances that deplete the ozone layer.
Limiting the use of substances that deplete the ozone layer is needed
No longer use CFC
195 countries in the world agreed to participate in the Montreal Protocol (Canada) 1994 to eliminate the use of substances that deplete the ozone layer such as CFC, HCFC and HFC (these substances are used in cooling mechanism of air-conditioners).
Recognizing the importance of the elimination of toxic substances, although Vietnam joined the Montreal Protocol in January 1994, Vietnamese businesses did not use CFC in cosmetics production. In addition, Vietnamese businesses have strictly complied with regulations, contributing to reducing 3.6 tonnes CFC11 in using air-conditioners in the garment and textile sector, 5.8 tonnes CFC12 in using automotive air-conditioners and 40 tonnes CFC in using commercial cooling equipment. Vietnam has also achieved positive results in excluding the annual consumption of substances that deplete the ozone layer. Together with these achievements, the United Nations Environment Program recognized positive contributions of Vietnam in the implementation of the convention and the Montreal Protocol.
Department of Meteorology, Hydrology and Climate Change under the Ministry of Natural Resources and Environment Deputy Director Nguyen Khac Hieu said that if Vietnam receive the full support in terms of finance and technology from international organizations, the country could completely exclude the use of HCFC in 2025.
According to the Montreal Protocol, in 2013, Vietnam is only allowed to consume HCFC at baseline (221.2 tonnes). From October 2015 to the end of 2019, Vietnam must decline the use of HCFC by 10 percent of baseline. This figure must be declined by 35 percent from 2020 and the use of HCFC will be completely excluded in 2030. In terms of equipment repairing and maintaining sector, the use of HCFC will be completely excluded in 2040. The World Bank and the Department of Meteorology, Hydrology and Climate Change under the Ministry of Natural Resources and Environment completed the adoption of the project on eliminating toxic substances that deplete the ozone layer. The first period of the project was carried out. According to calculations, Vietnam needed more US$20-25 million to completely exclude HCFC.
To achieve the goal, Vietnam is calling for people to work together to protect the ozone layer by changing consumer behavior, such as no longer using air-conditioners, painting houses by brushing or rolling and limiting the use of plastic packaging. Businesses should not install new equipments that use HCFC./.
