Role of the DOE
Certification is performed by a designated operational entity (DOE).
A DOE may only perform either validation or verification and certification in respect of a single CDM project activity, unless the Executive Board specifically approves a request to allow a single DOE to perform all these functions:
A designated operational entity shall:
- Perform one of the following functions relating to a given CDM project activity: validation or verification and certification. Upon request, the Executive Board may, however, allow a single designated operational entity to perform all these functions within a single CDM project activity (3/CMP.1, Annex, paragraph 27(e)).
It is a matter for the project participants to select and engage a DOE to perform certification. 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 certify emission reductions from projects in each sector.
