Objectif To analyze critical decision-making issues related to climate change policies, particularly the timing of decisions vs the costs of alternative greenhouse gases' abatement trajectories; this work is intended to help to meet specific targets, and to derive policy relevant conclusions from Integrated Assessments on climate change.OBJECTIVES: To analyze critical decision-making issues related to climate change policies, particularly the timing of decisions vs the costs of alternative greenhouse gases' abatement trajectories; this work is intended to help to meet specific targets, and to derive policy relevant conclusions from Integrated Assessments on climate change. DESCRIPTION: The project carries out a set of parallel simulation exercises to clarify some of the following issues: cost-efficiency of an earlier phasing out of CFC, costs and benefits of postponing action in the case of greenhouse effect, variations in patterns of development and costs of inertia, trade-offs between abating CO2, CH4 and SO2 emissions. The exercises are carried out using both existing Integrated Assessment Models and models still in phase of development. The URGENCE model is utilised as a simulation tool for analysing the cost of climate surprises. This model is coupled with DIAM, a theorically simple optimal control integrated model. An integrated climate change assessment model, the Climate Framework for Uncertainty, Negotiation and Distribution, is utilised in order to assess the value of no-regret potential and the value of carbon-free technical progress. Such model is complemented by a Negishi welfare optimisation integrated climate assessment model, ALICE, and by the Holistic Optimal Growth (HOG) model to examine distributional issues. The MESSAGE and RAIN models are used to analyse the trade-offs between abating CO2, CH4 and SO2 emissions. They help to calibrate reference scenarios on the basis of the baseline scenarios of the World Energy Council On the basis of the above mentioned analysis, the project intends to illuminate the most efficient and effective options available to address climate change.
