The Conference of the Parties (COP), by decision 1/CP.16, decided to establish a Technology Mechanism, comprising a Technology Executive Committee and a Climate Technology Centre and Network (CTCN).1 The COP, by decision 2/CP.17, requested the CTCN, once it is operational, to elaborate its modalities and procedures based on its terms of reference and to report to the COP through the subsidiary bodies, at their thirty-eighth sessions, with a view to making a decision on this matter at COP 19. The COP, by decision 14/CP.18, decided that the United Nations Environment Programme (UNEP), as the leader of a consortium of partner institutions, be selected as the host of the Climate Technology Centre (CTC) for an initial term of five years, with possible renewal, if so decided by COP 23. It also requested UNEP, as the host of the CTC, to convene and facilitate, preferably prior to the thirty-eighth sessions of the subsidiary bodies, the 1st meeting of the Advisory Board of the CTCN, established by the same decision, to determine its operational modalities and rules of procedure for consideration by the subsidiary bodies at their subsequent sessions. SBSTA 38 noted the progress report on modalities and procedures of the CTCN and its Advisory Board.5 It encouraged the Advisory Board of the CTCN to conclude its work on this matter and submit its report on modalities and procedures of the CTCN and its Advisory Board to the COP through the subsidiary bodies, at their thirty-ninth sessions, with a view to Parties making a decision on this matter at COP 19. In response, UNEP has submitted the attached report (see the annex), dated 20 September 2013, which is reproduced here as submitted, without formal editing and with the original pagination
