Having considered the recommendations of the Sub-Committee on Project Review on the price of chemicals (UNEP/OzL.Pro/ExCom/22/15, para. 24), the Executive Committee decided to request the Secretariat and the Implementing Agencies to hold discussions on and review the process of setting the prices of ODS and other chemicals for the purpose of calculating incremental operating costs, taking fully into account the earlier decision of the Executive Committee on limiting the variation in prices to 20 per cent of the regional border price, and to prepare, by the Twenty-third Meeting of the Executive Committee, a paper outlining the process proposed to be followed.
