Role of the DOE
The process of verification is performed by a designated operational entity (DOE). In contrast to large-scale afforestation and reforestation (A/R) projects, the DOE engaged to conduct validation of a small-scale A/R (SSC A/R) project may also conduct verification and certification of that project:
A single designated operational entity may perform validation as well as verification and certification for a small-scale CDM project activity or bundled small-scale CDM project activities (4/CMP.1, Annex II, paragraph 20).
However, the DOE that submits the request for a renewed crediting period may not perform verification for the renewed crediting period:
Any DOE can be selected by project participants to perform this task, however for large scale projects the DOE that submits the request for renewal of the crediting period shall not perform verification for this the renewed crediting period (EB 36, Annex 43, footnote 2).
When preparing verification reports, DOEs must follow the requirements set out in the Validation and Verification Manual (VVM).
It is a matter for the project participants to select and engage a DOE to perform verification. The project participants have the discretion to decide which accredited DOE to engage and on what commercial terms.
The UNFCCC website includes a list with approved methodologies by sectoral scopes and shows the DOEs which are accredited to conduct verification in each sector.
