Recent G8 summits have taken up the issue of climate change. Climate change featured high on the agendas of the 2005 summit in Gleneagles and the 2007 summit in Heiligendamm. Henrike Peichert and Nils Meyer-Ohlendorf analyse in this paper the recent G8 Summit outcomes and their practical impacts on international climate change negotiations under the UNFCCC. The paper argues that G8 Summit outcomes seem to yield overall positive influence on the UNFCCC processes, although more ambitious action needs to be taken and – most importantly – implemented. The paper was presented at the 2007 annual Conference of the British International Studies Association in Cambridge (BISA) and is available for download.
