During the climate negotiations in Copenhagen in December, a proposed exclusion of nuclear power projects from national mitigation plans was removed from the texts. As a result, developing countries are able to include the use of nuclear energy in their list of mitigation actions to be sent to the UNFCCC. Decisions on whether or not nuclear or carbon capture and storage projects could be included in the Clean Development Mechanism (CDM) and JI after 2012 were deferred to later meetings.
