生态环境部禁用两类ODS化学品

Core Points - The Ministry of Ecology and Environment has announced a ban on the production of two categories of ozone-depleting substances (ODS) starting from January 1, 2026, specifically targeting household refrigerators and freezers using hydrofluorocarbons (HFCs) as refrigerants and polyurethane products using HCFC-141b as a foaming agent [1][2] - The ban is part of China's commitment to the Montreal Protocol and the Kigali Amendment, aiming to phase out HFCs and protect the ozone layer [1][2] Industry Impact - The polyurethane foam industry is a major consumer of HCFCs, with most sub-sectors having adopted alternative technologies, although some sectors like board and spraying still use HCFC-141b [1] - The household appliance industry, particularly in refrigerators and freezers, predominantly uses low-carbon and environmentally friendly isobutane as a refrigerant, with a penetration rate exceeding 90%, while only a small portion of export products still utilize HFCs [1][2] Technological and Economic Aspects - Isobutane has been successfully applied as a refrigerant for many years, with mature technology and a well-established industrial chain, and it is more cost-effective than HFCs, providing significant overall benefits [2] - All sub-sectors of the polyurethane industry have developed mature alternative technologies, allowing companies to choose substitutes based on product requirements [2] Regulatory Measures - The Ministry of Ecology and Environment will enhance supervision and inspection, imposing penalties on companies that violate the regulations [2] - The ministry plans to promote the implementation of the ban through public awareness, training, and guidance to ensure industries meet the phasing-out deadlines [2]
