A main focus area of the IMAGE model is to look at climate change mitigation strategies. For this, the IMAGE model is linked to the FAIR modeling framework. ([[Climate policy]]). This link allows to consider detailed climate policy configuration in support of negotiation processes, and also to do intertemporal optimization of mitigation strategies For this purpose, the [[FAIR model|FAIR]] system receives information from various parts of the main IMAGE system, including information on baseline emissions from energy, land use and industrial sources, the potential for reforestation and the costs to abate emissions in the energy system. The latter is provided in the form of dynamic marginal abatement cost ([[MAC]]) curves for different regions, gases and sources. Using demand and supply curves, the model determines the carbon price on the international trade market with buyers and sellers by volume, and the resulting net abatement costs for each region. Long-term reduction strategies can be determined by minimizing cumulative discounted mitigation costs. The FAIR calculations are fed back into the core IMAGE model to calculate impacts on the energy and land use systems. This implies that the system can evaluate measures in industry against those in land use, e.g. relevant for increased bio-energy production. But also to look into the potential impacts of climate policy such as avoided damages and co-benefits for air pollution.. | A main focus area of the IMAGE model is to look at climate change mitigation strategies.

The IMAGE framework can account for a wider set of energy policies than climate policy alone, including measures to promote access to modern energy and to improve energy security Moreover, it also possible to constrain or even ban the use of specific technologies in [[TIMER model|TIMER]] such as bio-energy, nuclear power or [[CCS]]. As before, the strength of IMAGE analysis is to look at linkages, synergy and trade-off across global change processes. Examples include the link between energy use and land-use for bio-energy, and the consequences of air pollution for human health. | The IMAGE framework can account for a wider set of energy policies than climate policy alone, including measures to promote access to modern energy and to improve energy security Moreover, it also possible to constrain or even ban the use of specific technologies in [[TIMER model|TIMER]] such as bio-energy, nuclear power or [[CCS]].
