Decision XXIII/12: Adoption of new destruction technologies for ozone‑depleting substances

Noting with appreciation of the report of the task force established by the Technology and Economic Assessment Panel in response to decision XXII/10 on destruction technologies for ozone‑depleting substances,

Noting that the task force recommends the addition of four technologies to the list of destruction processes approved by the parties and indicates that there is insufficient information to recommend one technology deemed to hold high potential,

To approve the highlighted destruction processes in the annex to the present decision for the purposes of paragraph 5 of Article 1 of the Montreal Protocol, as additions to the technologies listed in annex VI to the report of the Fourth Meeting of the Parties[1] and modified by decisions V/26, VII/35 and XIV/6;
To request the Technology and Economic Assessment Panel to continue to assess the plasma destruction technology for methyl bromide in the light of any additional information that may become available and to report to the parties when appropriate;
Also to request the Technology and Economic Assessment Panel to continue to investigate the issues raised in its 2011 progress report regarding performance criteria for destruction and removal efficiency compared to destruction efficiency, and regarding verification criteria for the destruction of ozone-depleting substances at facilities that use approved destruction technologies, and to submit a final report to the Open-ended Working Group at its thirty-second meeting;
