Decision XXI/3: Uses of controlled substances as process agents

Noting with appreciation the 2008 report of the Technology and Economic Assessment Panel;

Recalling Decision X/14 in which all Parties are asked to report to the Secretariat annually by 30September on their use of controlled substances as process agents, the levels of emissions from those uses and the containment technologies used by them to minimize emissions of controlled substances;

Noting that the report by Executive Committee on process agent uses in Parties operating under paragraph 1 of Article 5 of the Montreal Protocol (UNEP/Oz.L.Pro.WG.1/29/4) found that the adoption of technology that results in zero emissions of ozone-depleting substances used as process agents has become the norm in Parties operating under paragraph 1 of Article 5 of the Montreal Protocol;

Noting that reporting by Parties operating under paragraph 1 of Article 5 on approved process agent projects under the Multilateral Fund does not replace the need to submit the required information under Decision X/14 to the Ozone Secretariat;

Noting with concern that only two Parties reported information consistent with Decision X/14 and that such limited data has impeded the Technology and Economic Assessment Panel in undertaking the level of analysis required;

Also noting that such limited information reported by Parties puts at risk the current exclusion of process agent uses of controlled substances from a Party’s annual consumption calculation;

  1. To request all Parties with process agent uses of controlled substances to submit the information required by Decision X/14 by 30 September each year to the Ozone Secretariat;
  2. To clarify that the annual reporting obligation shall not apply once a Party informs the Ozone Secretariat they do not use ozone-depleting substances as process agents as under Decision X/14, until they start doing so, and that this one-time procedure pertains to all Parties whether or not they are listed in Table B of Decision X/14;
  3. To request the Ozone Secretariat every year to write to those Parties that did not submit a document as under paragraph 2, report, requesting them to submit information consistent with Decision X/14;
  4. To request the Ozone Secretariat to bring cases of non-reporting to the attention of the Implementation Committee for consideration;
  5. To request the Technology and Economic Assessment Panel and the Executive Committee of the Multilateral Fund to prepare a joint report for future meetings, reporting on progress with phasing out process-agent applications, as sought by Decision XVII/6 (paragraph 6);
  6. To revisit this issue at the 30th Meeting of the Open-ended Working Group;
  7. To update Table A of Decision X/14 as per the Annex to this decision;
  8. To update Table B of Decision X/14 as per the Annex to this decision;
