(TN&MT) - It is expected that from 2024, Vietnam will establish quotas for manufacturers and importers of HFC (hydrofluorocarbon) substances, often used in the production of refrigeration equipment and car air conditioners. , fire extinguishing equipment... This is the first step in the roadmap to manage and gradually eliminate HFCs in Vietnam, moving towards eliminating 80% of consumption by 2045.
Limit consumption to nearly 8 thousand tons/year
To better understand the current situation of HFC consumption in Vietnam, the Department of Climate Change (Ministry of Natural Resources and Environment) and the consulting unit organized a survey of HFC consumption in the period 2018 - 2021 from businesses, customs and other sources. Other relevant information necessary for calculating and determining HFC consumption reduction. The results show that, in the last 3 years, HFC consumption has been stable at around 5.5 thousand tons, equivalent to emitting more than 10 million tons of CO2.
According to Resolution No. 64/NQ-CP dated September 4, 2019 of the Government on approving the Kigali Amendment and Supplement on the management of HFC substances within the framework of the Montreal Protocol, Vietnam will begin implementing the roadmap. The process of gradually eliminating HFCs from 2024, with the goal of not increasing the consumption of HFCs in the period 2024 - 2028 at the baseline consumption level. Gradually reduce consumption by 10% between 2029 and 2034, by 30% between 2035 and 2039, by 50% between 2040 and 2044, and by 80% on baseline consumption from 2045.
In 2021 alone, the largest consumption area is chillers and central air conditioners (36.6%), followed by air conditioners and heat pumps (19.7%), industrial refrigeration (15, 3%), fire extinguishing (15%). The remaining areas are transportation air conditioning, residential refrigeration, commercial refrigeration, transportation refrigeration, foam production, aerosol - solvents and other needs.
According to the roadmap for management and elimination of HFCs, in the period 2024 - 2028, Vietnam will only consume HFCs at the base level - a temporary estimate based on reported data is nearly 8 thousand tons, converted to equivalent emissions. emitting about 14 million tons of CO2. Ms. Nguyen Dang Thu Cuc - Deputy Head of the Department of Greenhouse Gas Emissions Mitigation and Ozone Layer Protection (Department of Climate Change) said that in 2022, the Department of Climate Change in coordination with the General Department of Customs organized Organizing propaganda for regulations in Decree 06/2022/ND-CP of the Government dated January 7, 2022 regulating greenhouse gas emissions mitigation, protecting the ozone layer and encouraging organizations to register to use apply and allocate quotas on the Public Service Portal of the Ministry of Natural Resources and Environment.
According to regulations, quotas will be determined according to quota management requirements, usage needs and average usage volume of the organization in the most recent 3 years. Quotas can only be used in the year of allocation, not exceeding total national consumption. Organizations that are allocated quotas and then export will be considered for additional import quotas that do not exceed the amount already exported. Quota adjustments and additions are made based on the organization's request, usage situation and balance on the total national quota.
Develop a plan to manage and eliminate HFC substances
According to Mr. Tang The Cuong - Director of the Department of Climate Change, in recent times, understanding the situation of HFC consumption in Vietnam is one of the activities to develop a plan to manage and eliminate HFC substances. of Vietnam in phase 1, from there, forecasting the growth trend in demand. This is the basis for determining the necessary mechanism, policy, investment and technical support interventions to achieve HFC consumption reduction according to international commitments; while ensuring the growth of the economy and industries, developing the workforce and strengthening actions to mitigate climate change.
Training session for technicians operating in the field of installation, maintenance, and repair services of refrigeration and air conditioning equipment
Based on Vietnam's HFC consumption by each sector, experts will propose focused interventions to eliminate substances that cause greenhouse effects with high global warming potential, substances that produce substitute products on the market and gradually reduce use in industries with large HFC consumption in Vietnam's total consumption. Industries with viable alternatives will be given decreasing priority over industries without alternatives.
To have a basis for establishing an HFC quota and licensing system, relevant agencies must manage and control at the border, monitor and report trade statistics (import/export) more carefully. Mr. Pipat Poopeerasupong - Program manager for ozone in the Asia-Pacific region, United Nations Environment Program, said that one of the challenges is to have statistics to monitor the amount of import and export of the country. each HFC medium separately according to Kigali regulations, meanwhile, not all HFC mixtures can be tested by the instrument. Customs officers will need to be professionally trained on this issue and how to integrate it with current working mechanisms to improve control capacity.
According to Mr. Ashraf El-Arini - representative of the World Bank, the Multilateral Fund has a financial mechanism to support developing countries in implementing activities that comply with the management roadmap and eliminate substances that deplete the cell layer. - ozone and causing the greenhouse effect according to the Montrel Protocol. In Vietnam, the Fund will focus on technical support to allocate quotas fairly and transparently; Support customs in implementing new import codes for HFCs and HFC mixtures, as well as conversion activities in service industries that consume a lot of HFCs.
The loss rate of HFC during use in Vietnam is up to 15%. This shows that there will be many opportunities to reduce leaked consumption during equipment repair and maintenance through training of technical staff. Businesses can also start converting from one category or product model and then gradually switch to other models, not all at the same time. This is also what Thailand and Malaysia are doing.
