The relevant person in charge of the Department of Atmospheric Environment of the Ministry of Ecology and Environment answered reporters' questions on the "China List of Controlled Ozone Depleting Substances"

Recently, the Ministry of Ecology and Environment, the National Development and Reform Commission, and the Ministry of Industry and Information Technology have revised and released the "China List of Controlled Ozone Depleting Substances" (Announcement No.

Q: What is the background of the release of the "List"?

Answer: In 2010, the State Council promulgated the "Regulations on the Management of Ozone Depleting Substances" (hereinafter referred to as the "Regulations") to implement the "Vienna Convention for the Protection of the Ozone Layer", "Montreal Protocol on Substances that Deplete the Ozone Layer" (hereinafter referred to as the "Protocol") and develop ozone-depleting substances.

In October 2016, the 28th Conference of the Parties to the Protocol reached the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer (hereinafter referred to as the Amendment), and 18 hydrofluorocarbons (HFCs) were included The scope of the Protocol's control has become the ninth class of controlled substances

Question: What is the basis for the revision of the "List"?

Answer: Article 2 of Chapter 1 of the "Regulations on the Administration of Ozone Depleting Substances" stipulates that the "Ozone Depleting Substances" referred to in the "Regulations" refers to chemicals listed in the "China List of Controlled Ozone Depleting Substances", the "China Controlled Ozone Depleting Substances List" 》It shall be formulated, adjusted and announced by the competent department of ecological environment of the State Council in conjunction with relevant departments of the State Council

Q: What are the contents of this revision?

Answer: This revision mainly includes the following two aspects:

(1) Further improve the management scope of the "List"

One is to add new controlled substances

(2) Align the contents contained in the Annex to the List and the Protocol

One is to change the Chinese chemical name of CFC-113 (chemical formula C2F3Cl3) from “1,1,2-Trichloro-1, 2,2-Trifluoroethane" was revised to "Trichlorotrifluoroethane", and the chemical Chinese name of CFC-114 (chemical formula C2F4Cl2) was changed from "1,2-dichloro-1,1,2,2-"Fluoroethane" was revised to "dichlorotetrafluoroethane", so that the isomers CFC-113a, CFC-114a, etc.

Question: How to implement control over HFCs that are newly included in the "List"?

Answer: According to the compliance requirements of the "Amendment", China must freeze the production and use of HFCs at the baseline level from 2024 (the baseline is the average value of HFCs from 2020 to 2022 plus 65% of the baseline level of hydrochlorofluorocarbons, based on carbon dioxide The equivalent is calculated in units).
