I, Stephen Montzka, residing in the United States, a consulting expert of the Decision XXXI/3 Task Force on Unexpected Emissions of CFC-11 declare as follows.

1. I have read the Conflict of Interest and Disclosure Guidelines for the Technology and Economic Assessment Panel, Its Technical Options Committees and Temporary Subsidiary Bodies (“the COI Guidelines”) as adopted by the Meeting of the Parties in Decision XXIV/8.
2. I am a research chemist at the National Oceanic and Atmospheric Administration. My responsibilities include measuring trace gas concentrations over time throughout the global atmosphere, and providing interpretations of those results to provide insight into changing emissions of these gases on national and global scales.
3. This declaration constitutes my written agreement, pursuant to paragraph 8 of the COI Guidelines, to comply with the Guidelines.  I understand that this written agreement is a condition of my service.
4. My interests, and those of my personal partner and dependents, include the following (if answer is yes, describe briefly)
   • Proprietary interests: I do not have proprietary interest in a substance, technology or process to be considered by TEAP or any of its TOCs or temporary subsidiary bodies (e.g. task forces).
   • Financial interests: I do not have ownership, shares or bonds in an entity with an interest in the subject matter of the meeting or work.
   • Employment, consultancy, directorship or other positions: I act on the Council of Fellows for the University of Colorado’s Cooperative Institute for Research in Environmental Science (unpaid).  I am a part of the WMO/UNEP Science Assessment Panel.
   • Government advice and other policy development: As a U.S. Government Employee I share results of my research and my interpretation of those scientific results with representatives of other Agencies of the US Government or Congress when requested, which is not on a regular basis.  As a member of the WMO/UNEP’s Science Assessment Panel I write reports, give presentations, and provide consultation on atmospheric trends of ozone-depleting to the Parties to the Montreal Protocol and other organizations that are interested in this information.  In either of these activities, my work is only related to providing policy relevant scientific information; I am not involved in formulating policy.
   • Paid research activities, fellowships or grants: I receive a salary from the US Government to perform research and communicate those results to other scientists, the public, policymakers, and industry representatives, as needed.
   • Other interests: none of relevance
5. The source of funding for my participation in the work of the Decision XXXI/3 Task Force on Unexpected Emissions of CFC-11 is through the National Oceanic and Atmospheric Administration (US taxpayer funded)
6. Pursuant to paragraph 11 of the COI Guidelines, I declare that I have not declined to disclose information falling within paragraph 10 of those Guidelines. 
7. I undertake to disclose any material change to any of the above information, pursuant to paragraph 9 of the COI Guidelines, within 30 days of any such change.
8. I undertake to make further declarations of interest annually for so long as I remain a member of the Decision XXXI/3 Task Force on Unexpected Emissions of CFC-11.
9. I understand that this DOI will expire no later than one year after I have signed it.
