Can CERs be forwarded to the national registry of a Party that did not provide the letter of approval?

The UNFCCC Secretariat has confirmed that CERs may only be forwarded to accounts held by project participants in the national registry of the Annex I country that authorised their participation in the CDM project (or their temporary holding account in the CDM registry, prior to the international transaction log being operational)

It is not possible for CERs to be forwarded from the CDM registry to an account in the national registry of an Annex I Party that did not provide the Annex I approval.
