Process matters: building a future climate regime with multi-processes

How do current processes in international climate-related institutions affect the architecture of a future climate regime, particularly various international negotiating processes related to climate change? A plausible image of future climate regime is developed to address this question. Three plausible scenarios are described for the next decade using the scenario-planning approach. Based on this, the scope for an internationally acceptable climate regime beyond 2012 is developed. The current processes under the UNFCCC, the Kyoto Protocol, and those outside the UN arena are encapsulated into three scenarios. Each scenario has a set of relatively preferable types of commitments, which differ from each other. Each process is likely to result in the establishment of one particular institution. Linkages are developed between the three institutions so that the climate regime as a whole will be environmentally effective. The three institutions are likely to converge in the long run, as countries' views on both climate change and a future climate regime converge.
