Noting with appreciation the support provided by the Ozone Secretariat to the parties in developing revisions to the reporting forms and their instructions,

Noting the parties’ intent that the global-warming-potential values listed for the group of isomers for HCFC‑123 and for HCFC-124 listed in Annex C should apply to the most commercially viable isomers, listed as HCFC-123** and HCFC‑124**,

Noting also that there are no global-warming-potential values assigned to HCFC-141 and
HCFC-142 in Annex C of the Kigali Amendment and that HCFC-141b and HCFC-142b represent the most commercially viable isomers of those substances,

1. To approve the revised forms and instructions for reporting data in accordance with the reporting obligations under the Protocol, as set out in annex III to the report of the Thirtieth Meeting of the Parties;[1]
2. To clarify that decision XXIV/14, by which parties are requested to enter a number in each cell in the data reporting forms that they submit, including zero, where appropriate, rather than leaving the cell blank, does not apply to cells where the information is to be provided on a voluntary basis;
3. To instruct the Ozone Secretariat to use the global-warming-potential values listed for HCFC‑123 and HCFC-124 in Annex C for HCFC-123** and HCFC-124**, respectively, when calculating the hydrofluorocarbon baselines of parties with consumption or production of HCFC‑123** and HCFC-124** in their respective baseline years;

Also to instruct the Ozone Secretariat to use the global-warming-potential values of HCFC-141b and HCFC‑142b for HCFC-141 and HCFC-142, respectively, when calculating the hydrofluorocarbon baselines of parties with past consumption or production of HCFC-141 and HCFC‑142 in their respective baseline years;
