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.

Key words: HFC-23, Abatement policy, Performance evaluation, Multilateral Environmental Agreements (MEAs)
