The IPCC Panel at its 26th session called on partnerships and collaboration to address climate change, as well as a better understanding of social and economic dimensions of mitigation and adaptation. The Panel recalls its support for decoupling the climate modeling work from the emission scenario development work, in order to allow climate modelers a quick start with their work after the completion of the AR4. Also, the Panel now requests the Steering Committee on New Scenarios to prepare a few benchmark concentration scenarios through the IPCC Expert Meeting 19-22 September 2007 in Noordwijkerhout, The Netherlands. These benchmark concentration scenarios should be compatible with the full range of stabilization, mitigation and baseline emission scenarios available in the current scientific literature.

The Twenty-Seventh Session focused on the adoption and approval of the draft Synthesis Report of the IPCC Fourth Assessment Report (AR4). as indicated in the agenda, a discussion paper about the future of the IPCC was introduced, among other items that required consideration and decision by the Panel.
