Mitigation & Ancillary benefits
Work Package 4: Mitigation. Modelling platforms to estimate the mitigation costs of stabilisation scenarios include POLES (bottom-up global energy system), PACE (multi-sector, multi-region computable general equilibrium framework) and GEM-E3 (Europe and World CGE). Using several models explores the robustness of mitigation estimates to theoretical specifications. The models will be updated to cover non-CO2 gases, induced technological change and new abatement options. ClimateCost uses the suite of models currently used by DG Environment in their modeling analysis for mitigation policy, so the output from the project will feed directly into policy relevant analysis.
Work Package 5: Ancillary Benefits. Mitigation policies or scenarios aimed at reducing greenhouse gas emissions may have important ancillary benefits. These include reductions in air pollution, and they are particularly important as these benefits are immediate. Detailed air quality modelling of the ancillary benefits of mitigation will adopt a bottom-up assessment quantifying benefits in physical terms and monetary values.
