    Countries included within the model are grouped into 17 regions clustered by geography, income and the structure of energy demand.

    The regional disaggregation is now flexible and the model can be run on different model configurations, typically from 5 to 17 regions, or more.

    WITCH features any regional aggregations in the so-called coalitions. Some common coalitions are:

    • regional coalitions : each region is mapped to a coalition containing only this region.
    • world coalition : a coalition containing all the world regions.

    Coalitions and regions interact with each others because of the presence of economic (technology, exhaustible natural resources) and environmental global externalities.
