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.
Figure 1.1: Regions of the WITCH model (except that India and Indonesia are not detached from their former regions, sasia and easia, respectively).
The 17 regions are:
| Region | Countries |
|---|---|
| cajaz | Canada, Japan, New Zealand |
| china | China, including Taiwan |
| easia | South East Asia |
| india | India |
| indonesia | Indonesia |
| kosau | South Korea, South Africa, Australia |
| laca | Latin America, Mexico and Caribbean |
| mena | Middle East and North Africa |
| neweuro | EU new countries + Switzerland + Norway |
| oldeuro | EU old countries (EU-15) |
| sasia | South Asia |
| ssa | Sub Saharan Africa |
| te | Non-EU Eastern European countries, including Russia |
| usa | United States of America |
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.
