The type of analysis described in this section contains major uncertainties that increase with longer scenario periods. All processes involved are described in the respective model-specific component, together with the related uncertainties (see Policy intervention Tables in the parts above). The key uncertainties from a systems perspective are discussed here. | The type of analysis described in this section contains major uncertainties that increase with longer scenario periods.

The IMAGE framework may be used to analyse policy issues in different ways. Most frequently, technical interventions or assumed behavioural changes are implemented, and the results from alternative scenarios are used to answer 'what if' questions. However, the costs and policy measures to bring about such changes often cannot be modelled internally, and the feasibility of such options cannot be taken into account. Some economic instruments in the agro-economy model (e.g., a meat tax) can be modelled explicitly, and also specific policies, such as those on {{abbrTemplate|REDD+}}, biofuels, or additional protected areas, can be modelled explicitly for their economic and system-wide effects. Other important transitions, such as behavioural change cannot be modelled. | The IMAGE framework may be used to analyse policy issues in different ways.
