Thirteenth Meeting of the Parties (Colombo, 16 - 19 October 2001)

Decision XIII/5: Procedures for assessing the ozone-depleting potential of new substances that may be damaging to the ozone layer

The Thirteenth Meeting of the Parties decided in Dec. XIII/5:

Understanding that “new substances” are those believed to deplete the ozone layer and to have the likelihood of substantial production but not listed as controlled substances under Article 2 of the Protocol,

Mindful of the requests to Parties under decision IX/24 and decision X/8 to report to the Ozone Secretariat new substances being produced in their territory,

Recalling decision XI/19 on the assessment of new substances, which requests the Technology and Economic Assessment Panel and the Scientific Assessment Panel to develop criteria to assess the potential ODP of a new substance and to produce a guidance paper on public/private sector partnerships in this assessment,

Understanding the urgency and the benefit of disseminating information on new substances that enables individual Parties to limit or ban the use of those substances as soon as possible,

Noting the desirability of having a standardized and independent ODP analysis in order to ensure consistent and reproducible results,

  1. To request the Secretariat to keep the list of new substances submitted by Parties pursuant to decision IX/24 on the UNEP Website up to date and to distribute the current version of the list to all Parties about six weeks in advance of the meeting of the Open-ended Working Group and the Meeting of the Parties;
  2. To ask the Secretariat to request a Party that has an enterprise producing a listed new substance to request that enterprise to undertake a preliminary assessment of its ODP following procedures to be developed by the Scientific Assessment Panel and to submit, if available, toxicological data on the listed new substance, and further to request the Party to report the outcome of the request to the Secretariat;
  3. To call on Parties to encourage their enterprises to conduct the preliminary assessment of its ODP within one year of the request of the Secretariat and, in cases where the substance is produced in more than one territory, to request the Secretariat to notify the Parties concerned in order to promote the coordination of the assessment;
  4. To request the Secretariat to notify the Scientific Assessment Panel of the outcome of the preliminary assessment of the ODP to enable the Panel to review the assessment for each new substance in its annual report to the Parties and to recommend to the Parties when a more detailed assessment of the ODP of a listed new substance may be warranted.

Tenth Meeting of the Parties (Cairo, 23-24 November 1998)

Decision X/8: New substances with ozone-depleting potential

The Tenth Meeting of the Parties decided in Dec. X/8:

Recalling that, under the Montreal Protocol, each Party has undertaken to control the global emissions of ozone-depleting substances with the ultimate objective of their elimination,

Recalling that decision IX/24 requested Parties to discourage the development and promotion of substances with a significant potential to deplete the ozone layer and provides a procedure for notifying such substances to the Secretariat and their evaluation by the Science Assessment Panel and the Technology and Economic Assessment Panel,

  1. That all Parties should take measures actively to discourage the production and marketing of bromochloromethane;
  2. To encourage Parties, in the light of reports from the Scientific Assessment Panel and the Technology and Economic Assessment Panel, to take measures actively, as appropriate, to discourage the production and marketing of new ozone-depleting substances;
  3. That should new substances be developed and marketed which, following application of decision IX/24, are agreed by the Parties to pose a significant threat to the ozone layer, the Parties will take appropriate steps under the Protocol to ensure their control and phase-out;
  4. That Parties should report to the Secretariat, as far as possible by 31 December 1999, and as necessary thereafter, on any new ozone-depleting substances notified and evaluated under the terms of decision IX/24 being produced or sold in their territories, including the nature of the substances, the quantities involved, the purposes for which these substances are being marketed or used and, if possible, the names of the producers and distributors;
  5. To request the Technology and Economic Assessment Panel and the Science Assessment Panel, taking into account, as appropriate, assessments carried out under decision IX/24, to collaborate in undertaking further assessments:
    1. To determine whether substances such as n-propyl bromide, with a very short atmospheric life-time of less than one month, pose a threat to the ozone layer;
    2. To identify the sources and availability of halon-1202;
    3. and to report back to the Meeting of the Parties as soon as possible, but not later than the Twelfth Meeting of the Parties;

  6. To request the legal drafting group which the Open-ended Working Group may establish to consider and report back to the Eleventh Meeting of the Parties through the Open-ended Working Group on the options available under the Montreal Protocol to introduce controls on new ozone-depleting substances.

Ninth Meeting of the Parties (Montreal, 15-17 September 1997)

Decision IX/24: Control of new substances with ozone-depleting potential

The Ninth Meeting of the Parties decided in Dec. IX/24:

  1. That any Party may bring to the attention of the Secretariat the existence of new substances which it believes have the potential to deplete the ozone layer and have the likelihood of substantial production, but which are not listed as controlled substances under Article 2 of the Protocol;
  2. To request the Secretariat to forward such information forthwith to the Scientific Assessment Panel and the Technology and Economic Assessment Panel;
  3. To request the Scientific Assessment Panel to carry out an assessment of the ozone-depleting potential of any such substances of which it is aware either as a result of information provided by Parties, or otherwise, to pass that information to the Technology and Economic Assessment Panel as soon as possible, and to report to the next ordinary Meeting of the Parties;
  4. To request the Technology and Economic Assessment Panel to report to each ordinary Meeting of the Parties on any such new substances of which it is aware either as a result of information provided by Parties, or otherwise, and for which the Scientific Assessment Panel has estimated to have a significant ozone-depleting potential. The report shall include an evaluation of the extent of use or potential use of each substance and if necessary the potential alternatives, and shall make recommendations on actions which the Parties should consider taking;
  5. To request Parties to discourage the development and promotion of new substances with a significant potential to deplete the ozone layer, technologies to use such substances and use of such substances in various applications.
