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

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

    The 17 regions are:

    easia South East Asia
    india India
    indonesia Indonesia

    sasia South Asia
    ssa Sub Saharan Africa
    te Non-EU Eastern European countries, including Russia

    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.
