The policy decision-support model FAIR, which is part of the IMAGE 2.4 framework, is widely used to assess the environmental and abatement-cost implications of international regimes for the differentiation of future emission reductions of greenhouse gases (GHGs). The model links long-term climate targets and global reduction objectives with regional emission allowances and abatement costs and, as such, accounts for the Kyoto mechanisms. FAIR consists of three sub-models: a simple climate model (basically the IMAGE 2.4 climate model), an emission allocation model and a cost model. The cost model uses marginal abatement cost curves from both the energy- and industry-related carbon dioxide emissions modelled by the TIMER 2.0 model and the carbon sinks of the IMAGE model. The model has been used to assess different policy regimes and allocation schemes for stabilising greenhouse gas concentrations at low stabilisation levels. In these studies the FAIR model was also used to develop global emission pathways that lead to a stabilisation of the atmospheric GHG concentration, and to distribute the resulting global emission reduction burden among the different regions, gases and sources in a cost-optimal way.
