Nuclear projects are essentially ineligible to be registered as CDM projects, since Annex I Parties cannot use certified emission reductions (CERs) to meet their quantified emission limitation and reduction commitments under the Kyoto Protocol:
The Conference of the Parties, ...
Recognising that Parties included in Annex I are to refrain from using certified emission reductions generated from nuclear facilities to meet their commitments under Article 3, paragraph 1 (17/CP.7, Preamble).
This decision was confirmed by the COP/MOP at 3/CMP.1:
The Conference of the Parties serving as the meeting of the Parties to the Kyoto Protocol,
Decides to confirm, and give full effect to any actions taken pursuant to, decision 17/CP.7 and to any other relevant decisions by the Conference of the Parties (3/CMP.1, paragraph 1).
