Intergovernmental Panel on Climate Change, Twenty Fifth Session, Port Louis, Mauritius, 26-28 April 2006

Among other topics, the panel introduced a proposal for further work on emission scenarios, which was developed based on the recommendations of the Task Group on New Emission Scenarios, established following a decision by the Panel at its 23rd Session. In the plenary debate several countries expressed support for the proposal and some underlined the need to also cover the requirements of impact, adaptation and vulnerability studies, the importance of regional scenarios and developing country involvement in scenario development. Some concern was expressed that integrated scenarios may go beyond the scope of the IPCC. Different views were expressed about the IPCC role in scenario development, including the view that the IPCC should no longer itself commission or direct scenario development. The suggestion was also made to draw on the expertise of the Task Group on Data and Scenario Support for Impact and Climate Assessment (TGICA). It was recommended to take a clear decision on the future role of the IPCC and to focus in the further consultations on aspects where urgent decisions were required
