4. Process for nomination of TOC members Appointments or re-appointments may be submitted by a Party, by TEAP co-chairs or by the TOC co-chairs themselves. TOC co-chairs will consult the focal point of the relevant Party, unless the nomination originates from the focal point. Comments (in all instances) should be provided within 30 days. Wherever possible, appointments or re-appointments will be staggered to avoid discontinuity of expertise in the TOCs The Ozone Secretariat will establish and maintain a record on its website of the current appointment terms in order that proposals for re-appointment can be initiated in good time 4 M o n t r e a l P r o t o c o l O E W G - 3 4, 14 - 18 J u l y 2 0 14, Paris

5. Considerations for TOC Configurations (1) TOC co-chairs are continually reviewing and recruiting new members to satisfy TOC requirements for expertise and balance Appointments can happen throughout the year, when existing members retire from a TOC, or a lack of expertise is identified More commonly, a review of TOC membership is done after the completion of a TEAP progress, assessment or task force report. 5 M o n t r e a l P r o t o c o l O E W G - 3 4, 14 - 18 J u l y 2 0 14, Paris

6. Considerations for TOC Configurations (2) As per Dec XXIII/10, unless already reappointed, TOC member appointments will expire at end of 2014. Co-chairs of each TOC are actively reconfiguring their committees Considered each TOC separately: General scope of work and future workload 2014 Assessment configuration 2015-2018 configuration Post 2018 configuration TOC options considered: combining, dividing, creating new committee(s), maintaining status quo 6 M o n t r e a l P r o t o c o l O E W G - 3 4, 14 - 18 J u l y 2 0 14, Paris

7. Definitions Corresponding Members are nominated in full consultation with the national focal point of the relevant party and appointed by the TOC co ‑ chairs for a period of no more than four years but participate solely by electronic/telephonic means and do not attend physical meetings of the TOC. Consulting Experts are not members and do not participate in decision-making; they offer expertise that may not currently reside on the committee and are generally available to participate in committee discussions or activities as needed (physically or by electronic/telephonic means). 7 M o n t r e a l P r o t o c o l O E W G - 3 4, 14 - 18 J u l y 2 0 14, Paris

8. Summary of current and estimated TOC membership 2014 Assessment 2015-2018Post-2018 CTOC14 ~17 ~15 FTOC18 18-24*12-18** HTOC21 ~18 ~15 MTOC26 ~15*** ~15 MBTOC29 20-25 RTOC39 33-3825-38 * One third Corresponding Members ** Two Thirds Corresponding Members *** 3-4 corresponding sterilants members, 10-12 MDI members, mostly corresponding, unless issues emerge

9. CTOC membership 2014 Assessment 2015-2018Post-2018 CTOC14 ~17 ~15  Configuration will not necessarily change for the 2018 Assessment Report and is anticipated at about 17 members.  CTOC will continue to consider what portion of future membership may be comprised of Corresponding Members and/or Consulting Experts to ensure the required expertise.

10. FTOC membership 2014 Assessment 2015-2018Post-2018 FTOC18 18-24*12-18** * One third Corresponding Members ** Two Thirds Corresponding Members Configuration will not necessarily change fundamentally for the 2018 Assessment Report and is anticipated at about 18-24 members. Input from non-A5 members will remain important, but is likely to be managed largely through Corresponding Members from 2015. It is hoped that additional members can be engaged with a regulatory background. Co-chairs are seeking to recruit members with expertise in sectors with have transitions still ahead. These include extruded polystyrene and PU Spray Foam where future transition strategies remain unclear. There is also a need to keep access to specific expertise on bank management issues, likely to be via Consulting Experts or through membership of TSBs.

11. HTOC Membership 2014 Assessment 2015-2018Post-2018 HTOC21 ~18 ~15 As of April 2014, several members have resigned from the committee and will not be re-appointed or will have appointment terms of less than four years. As of 1 January 2015, HTOC proposes to continue with a reduced membership of approximately 18 members excluding any Consulting Experts that may be appointed by the co-chairs. Further reductions in membership will occur over the coming years with an eventual membership of approximately 15.

12. MTOC membership (1) 2014 Assessment 2015-2018Post-2018 MTOC26 ~15* ~15 * 3-4 corresponding sterilants members, 10-12 MDI members, mostly corresponding, unless issues emerge MTOC proposes to continue with a reduced membership to a core group of about 15 members, who operate by correspondence where possible or meet face to face when necessary, and a wider circle of Consulting Experts whose advice is sought on a corresponding basis only.

13. MTOC membership (2) Amalgamating membership into another TOC (such as CTOC) as suggested previously was found to have disadvantages: Other TOCs may not appreciate important emerging issues within the medical sector; it may be even more difficult to get funding for member participation in a TOC that does not appear to have any relevance to a member’s area of expertise; and most importantly, MTOC does not believe that this would provide sufficient flexibility or range of opinions to advise Parties on emerging medical issues.

14. MBTOC membership 2014 Assessment 2015-2018Post-2018 MBTOC29 20-25 MBTOC reunited into a single body. Working groups are assigned to different tasks (including CUNs), and recommendations are discussed and agreed by consensus in plenary. Members with specific expertise can participate in those issues they know best, and the committee fully participates in the decision-making process. In 2014, membership reduced from 36 to 29 as a result of resignations due to funding and personal reasons. As of 2015, a membership of 20-25 members is envisioned. This adjustment may include new members to replace or strengthen critical areas of expertise, such as remaining non-A5 CUNs, A5 issues and phase-out efforts conducted in A5 countries seeking CUEs. Retaining expertise in QPS, soils and structures and commodity uses for both non-A5 and A5 Parties is essential.

15. RTOC membership 2014 Assessment 2015-2018Post-2018 RTOC39 33-3825-38 For future assessments, there might be changes to the domestic refrigeration and mobile AC chapters with respect to the number of experts and chapter placement in the RTOC Assessment report. RTOC sees significant benefits in maintaining its current membership configuration and in the way assessment reports are developed. Even where change in emphasis may occur, i.e., by adding new members to strengthen the chapters on commercial refrigeration and stationary air conditioning, the size of the committee is estimated to remain at more or less the existing level (25-38 members).

16. Options to streamline TEAP annual Progress Report All TOC chapters will continue to follow a similar format for consistency and ease of consultation, and focused on information relevant to the upcoming meetings of Parties. Chapters will indicate when there is no significant new technical or economic information or, if there is new information, that this is incorporated in another report. CUNs, EUNs, and reports responding to specific Decisions will no longer be part of progress reports but will be separate volumes. Decisions that are relevant to a report will continue to be included in an Annex; in future, reports could provide the corresponding web link (URL) to Decisions that link to the Ozone Secretariat website. Although the option was considered for reporting every other year, TEAP considered that two years was too long of a lag for providing updated information to parties. 16

17. Status of TOC reappointments Dec XXIII/10 par. 9: the terms of all the members of the … technical options committees shall otherwise expire at the end… 2014…in the absence of reappointment To date, the TOC co-chairs have made progress in implementing this requirement with limited difficulties While each TOC is at a different stage of completion, with some being close to completion and others just beginning the process, TEAP does not anticipate the need for Parties to extend the 2014 expiration date based on the experience to date The terms of these reappointments are for no more than 4 years, with start dates of January 1st of the year following the reappointment. This aligns the membership terms of appointment with the quadrennial Assessment Report periods. 17 M o n t r e a l P r o t o c o l O E W G - 3 2 m e e t i n g, 2 3 - 2 7 J u l y 2 0 12, B a n g k o k
