** Important Announcement **

The Executive Board of the CDM (the Board), at its 108th meeting (EB 108), agreed on temporary measures pending guidance from the Conference of the Parties serving as the meeting of the Parties to the Kyoto Protocol (CMP) at its sixteenth session, for the following submissions:

  • Requests for registration of project activities and programmes of activities (PoAs), renewal of crediting periods and PoA periods, and inclusion and renewal of crediting periods of component project activities that have a crediting period or PoA period starting on or after 1 January 2021;
  • Requests for issuance of certified emission reductions for emission reductions achieved on or after 1 January 2021.

The Board, at EB 109, adopted a clarification on the application of these temporary measures at the regulatory and operational levels. The CMP, at its sixteenth session, clarified the nature and implications of the temporary measures (Decisison 2/CMP.16, paras. 13-15). The Board at EB 113, revised the clarification to reflect the CMP decision.
