Role of the DOE

The process of certification 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).

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.
