摘要
三氟甲烷(HFC-23)是我国排放量最大的氢氟碳化物(HFCs),受到《联合国气候变化框架公约》和《关于消耗臭氧层物质的蒙特利尔议定书》的管控。2015年我国出台了HFC-23运行补贴政策,支持国内企业开展HFC-23的处置。通过对2014-2018年公开减排数据的汇总分析,发现运行补贴政策的实施有效地激励了企业的减排,受补贴企业HFC-23处置率达98%。2014-2018年累计减排HFC-23约5.20万t,折合6.08亿t CO2-eq。此外,对照国际公约未来履约义务,建议在运行补贴政策结束后尽快出台明确针对全行业的管控政策,包括定量化减排目标和统一的企业自主监测标准。
HFC-23 is an unintentional by-product of the production of HCFC-22, which is an important emission source of HFCs in China. Moreover, HFC-23 is under the control of UNFCCC and Montreal Protocol. An HFC-23 abatement policy was introduced in China in 2015, providing subsidies to support HFC-23 emission reduction. Analysis on the emission reduction verification reports indicates the policy brought about effectively incentive for HCFC-22 producers and their disposal rate of HFC-23 reached 98%. The cumulative emission reduction of HFC-23 from 2014 to 2018 reached about 52 kt(608 Mt CO2-eq). Additionally, some suggestions are given out to help fulfill the obligations of Multilateral Environmental Agreements(MEAs) after the closure of this policy in 2020.
