Role of the DOE

The process of verification is performed by a designated operational entity (DOE).  In contrast to large-scale projects, the DOE engaged to conduct validation may also conduct verification and certification:

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).

Also in contrast to large-scale projects, the DOE that submits the request for a renewed crediting period may perform verification for the renewed crediting period, since this limitation is expressed to apply only to large-scale projects:

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).

DOEs must follow the requirements outlined in the Validation and Verification Manual (VVM) to ensure quality and consistency in verification and validation reports.

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.
