The Sixteenth Meeting of the Executive Committee decided that ODS consumption should be calculated on the basis of either the year, or an average of the three years, immediately preceding project preparation.
(UNEP/OzL.Pro/ExCom/16/20, para. 32b).
The Twenty-sixth Meeting of the Executive Committee decided:
(a) to request the Implementing Agencies, in the preparation of projects, to take extreme care to ensure the reliability and accuracy of data on ODS consumption and make available to the Secretariat figures normally provided by enterprises on ODS purchased by the enterprises and ODS used in the products being produced;
(b) to request that the enterprises for which projects were being prepared made available their relevant records to provide the best available information to the Implementing Agencies concerning ODS purchased and used.
(UNEP/OzL.Pro/ExCom/26/70, Decision 26/13, para. 36(a, b)).
The Thirtieth Meeting of the Executive Committee decided as a follow-up to the decision in paragraph 32(b) in the report of the Sixteenth Meeting of the Executive Committee and decision 26/13, paragraphs (a) and (b), to request the Secretariat, in co-operation with the Implementing Agencies, to develop definitions and procedures leading to more transparency and consistency in calculating ODS phase-out in project documents and project completion reports (PCRs), and to report on the results to the Thirty-second Meeting of the Executive Committee.
