All countries wishing to undertake CDM activities are required, according to the Kyoto Protocol, to appoint a Designated National Authority (DNA). One of the key tasks of the DNA is to establish an efficient and transparent national CDM project approval procedure for the evaluation of project ideas submitted to the authority and, in particular, to verify the projects’ conformity to the national sustainable development criteria. Upon approval, the DNA is responsible for issuing the host country letter of approval (LoA) to the CDM project proponent, which is required before
the project can be registered by the Executive Board.
