Ozone Depleting Potential (ODP) of Refrigerants: Which Particular Values are Used?

Under the Montreal Protocol on Substances that Deplete the Ozone Layer, Article 7 of the Protocol requires all Parties, both developing countries (also called Article 5 countries) and developed countries, to provide statistical data on an annual basis, on various issued related to trade and production of ozone-depleting substances (ODS), covering CFCs, halons, carbon tetrachloride, methyl chloroform, HCFCs, HBFCs, bromochloromethane and methyl bromide to the Ozone Secretariat. This data is then used to calculate each Party’s official ODS consumption and production levels. The data reported includes information on: production; imports from and exports to Parties and non-Parties; imports and exports of ODS that have been recycled; amounts used for feedstock; amounts destroyed by technologies approved by the Parties; amount of methyl bromide used for quarantine and pre-shipment (QPS) applications.
