Under the roadmap to carry out the Montreal Protocol on protection of stratospheric ozone layer by phasing out ozone-depleting substances, Vietnam will begin managing and eliminating all fluorinated chemicals from 2024 toward reducing consumption by 10% during 2029-2034, 30% during 2035-2039, 50% during 2040-2044 and 80% from 2045.

Vietnam has proactively carried out the protocol and agreements that it has joined in, while aligning with international laws on regulations to improve state management over climate change and ozone layer protection.

In Decree No. 06/2022/ND-CP dated January 7, 2022 which details the reduction of greenhouse gas emissions and the protection of the ozone layer, the Government stipulates a roadmap to manage and phase out ozone depleting substances, as well as management principles and coordination responsibilities among state-owned agencies.

Details to implement the law on environmental protection in response to climate change, with guideline to use, collect, transport, recycle, reuse and treat the substances were laid down at the Ministry of Natural Resources and Environment (MoNRE)’s Circular No. 01/2022/TT-BTNMT dated January 7, 2022.

The Government also issued Decree No. 45/2022/ND-CP on July 7, 2022 specifying penalties for administrative violations in the field of environment, including those on the use of substances controlled under the Montreal Protocol.

The Department of Climate Change under the MoNRE joined hands with the Vietnam Society of Refrigeration and Air-conditioning Engineers and the Institute of Heat Engineering and Refrigerator to provide training for nearly 188 lecturers from colleges and vocational schools, and 3,068 technical staff from refrigeration equipment service and maintenance facilities nationwide.

 A wide range of activities have been held to support the state management work, including developing standards for capacity assessment and certification for air-conditioning technicians. National standards limiting the use of flammable expansion agents in foam production, and the use of flammable refrigerants in air-conditioners are critical to reducing HFC use.

The Montreal Protocol was signed in 1987 and entered into force on January 1, 1989. It is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.

To date, it has been ratified by 197 countries, and has been one of the most successful environmental agreements to date. A united global effort to phase out ozone-depleting substances means that today, the hole in the ozone layer is healing, in turn protecting human health, economies and ecosystems.

Vietnam became a signatory of the United Nations Framework Convention on Climate Change in 1992, the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol in 1994./.VNA
