Group 1: Compliance and Achievements - China has strictly fulfilled its obligations under international environmental conventions, achieving all phased compliance targets on schedule [1]. - As of now, China has eliminated approximately 628,000 tons of ozone-depleting substances, accounting for over half of the total elimination in developing countries [1]. - Over the past 30 years, China has progressively phased out ozone-depleting substances, preventing the emission of 26 billion tons of carbon dioxide equivalent greenhouse gases [1]. Group 2: Global Context and Future Outlook - Globally, 99% of ozone-depleting substances have been successfully eliminated, with the Antarctic ozone hole showing signs of healing [3]. - Scientific assessments indicate that the Earth's ozone layer is expected to recover to levels seen before 1980 by the middle of this century [3]. Group 3: Leadership Role - China has played a crucial leadership role in the gradual elimination of ozone-depleting chemicals and the reduction of hydrofluorocarbons, which contribute to climate change, under the framework of the Montreal Protocol [4].

Core Viewpoint - The Ministry of Ecology and Environment of China held a conference to commemorate the 40th anniversary of the Vienna Convention for the Protection of the Ozone Layer, highlighting China's significant efforts in phasing out ozone-depleting substances and promoting green low-carbon transformation in relevant industries [1] Group 1: Ozone Layer Protection Efforts - China has cumulatively eliminated approximately 628,000 tons of ozone-depleting substances, accounting for over half of the total phase-out in developing countries [1] - By the end of this year, China is expected to achieve an additional phase-out of over 90,000 tons of ozone-depleting substances [1] Group 2: Future Regulations - Starting from July 1 next year, China will completely phase out the use of hydrochlorofluorocarbons in the polyurethane foam, extruded polystyrene foam, and industrial cleaning sectors, three and a half years ahead of schedule [1]

Core Points - The new regulation aims to fulfill the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol, targeting the elimination of HCFC-141b as a blowing agent in polyurethane products by January 1, 2026 [1][2] - The polyurethane foam industry is a major consumer of ozone-depleting substances, specifically HCFCs, with HCFC-141b being the most significant due to its high ozone depletion potential (ODP) of 0.11 [2] - China has already achieved the first and second phase elimination targets, freezing HCFC-141b consumption in the polyurethane foam industry at baseline levels in 2013 and reducing it by 80% by 2023 [2] Industry Overview - The polyurethane foam industry includes various sectors such as refrigerated containers, refrigerators, electric water heaters, insulation pipes, solar water heaters, and more [1][2] - The majority of companies in the board production sector are small to medium-sized enterprises, with around 250 companies primarily located in Jiangsu, Zhejiang, Shandong, and Henan [3] - Since 2011, multilateral fund grants have supported 21 board production companies in replacing HCFC-141b, resulting in the elimination of approximately 3,644 tons, which is 29.2% of the total HCFC-141b that needs to be phased out in this sector [3] Progress and Remaining Challenges - Additional estimates suggest that companies have transitioned or utilized their own funds to eliminate around 8,750 tons of HCFC-141b, leaving less than 50 tons remaining to be phased out in the board sector, which is less than 0.4% of the total [4] - The spray foam sector also consists mainly of small to medium-sized enterprises, with about 300 companies located in Shandong, Jiangsu, Beijing, and Hebei [4] - Since 2011, grants have supported four spray foam companies in eliminating approximately 226 tons of HCFC-141b, accounting for 2.5% of the total required elimination in this sector [4] Alternatives and Future Plans - There are various mature alternatives to HCFC-141b available in the polyurethane foam industry, including hydrocarbons, water, hydrofluorocarbons, and fluorinated olefins, which have been successfully applied for years [5] - The cost of hydrocarbons and water-based blowing agents is relatively low, while hydrofluorocarbons and fluorinated olefins are more expensive [5] - In 2025, multilateral fund grants will support 15 combination ether companies in technical upgrades to eliminate HCFC-141b and promote alternative products in the relevant sectors [5]
