The certification report is a formal certification, produced by the designated operational entity (DOE), to confirm that the quantity of emission reductions stated in the verification report have been achieved.
The process of certification is set out in 3/CMP.1, Annex, paragraph 63:
The designated operational entity shall, based on its verification report, certify in writing that, during the specified time period, the project activity achieved the verified amount of reductions in anthropogenic emissions by sources of greenhouse gas emissions that would not have occurred in the absence of the CDM project activity. It shall inform the project participants, Parties involved and the Executive Board of its certification decision in writing immediately upon completion of the certification process and make the certification report publicly available (3/CMP.1, Annex, paragraph 63; previously 17/CP.7, Annex, paragraph 63).
Provided that the requirements of 3/CMP.1, Annex, paragraph 63 are met, the form and contents of the certification report are at the discretion of the DOE.
Upon receipt by the Executive Board, the certification report is considered to constitute a request for issuance of CERs:
The certification report shall constitute a request for issuance to the Executive Board of CERs equal to the verified amount of reductions of anthropogenic emissions by sources of greenhouse gases (3/CMP.1, Annex, paragraph 64; previously 17/CP.7, Annex, paragraph 64).
