This booklet provides a summary of the main analysis from the forthcoming report OECD (2008), "The Economics of Climate Change Mitigation". The analysis was developed under the joint guidance of the OECD Economic and Environment Policy Committees. The messages presented in this booklet are supported by two main modelling frameworks: The OECD ENV-Linkages model: a recursive dynamic multi-country and multi-sector general equilibrium model housed at the OECD, which incorporates a full representation of international trade flows and has been developed to examine global and regional macroeconomic impacts of climate change or other policies and related trade issues. For more information see OECD Economics Department Working Paper n. 653 (2008) available at The WITCH (World Induced Technological Change Hybrid) model: a forward-looking multi-country general equilibrium model with a detailed representation of the energy sector developed by the climate modelling group at the Fondazione Eni Enrico Mattei (FEEM), which is especially suited for the analysis of R&D and technology deployment policies and their interactions with price-based instruments. For more information see Each of these models has its strengths and weaknesses, and the results of any such model-based work need to be seen in this light. In this booklet, the results presented are generally a compilation of elements from the two models.
