Abstract : This paper examines prospects for compromise between competing perspectives on four key climate change issues: costs, level of domestic action, nvironmental integrity, and developing world involvement. It focuses on the policy issues stemming from the uncertainty about abatement costs. Based on extensive simulations of a model integration tool, SAP12 Stochastic Assessment of Climate Policies, 12 models, the analysis considers options for fine-tuning the Kyoto Protocol, such as concrete ceilings or levies on carbon imports; -environmental restoration payments- to be made on excess emissions; and credits for equestration activities in Annex B countries. It demonstrates that the restoration payment implemented through a safety valve emerges as a superior means of addressing the cost uncertainty issue. The paper concludes that had this approach been taken at the COP6 climate negotiations, there would have been substantial room for compromise on payments of $35 to $100 per ton of carbon. Examining the Marrakech climate accord, it derives some lessons for attempts at completing Kyoto-s unfinished business or at moving on to a new framework.
