When is a new letter of approval required?

The UNFCCC Secretariat has confirmed that a new letter of approval is required from the relevant designated national authority (DNA) when a new project participant is added (whether this takes place before or after registration).  This includes both the replacement of a project participant with another entity, or the addition of a new entity as a project participant (in addition to the existing project participants).

The letter of approval should authorise the participation of the new project participant in the CDM project activity, as required in the original letter of approval.

The letter of approval must be issued by the host Party for a replacement host Party project participant, and by the relevant Annex I Party for a replacement or additional Annex I project participant.

For host Parties that list Annex I project participants in the host Party letter of approval, the addition or replacement of an Annex I project participant prior to registration will require a new host Party letter of approval in addition to a new Annex I Party letter of approval.  This is because if the project design document (PDD) and the host Party letter of approval do not list the same project participants, the Executive Board will not register the project.

The position is summarised in the table below:
