GINFORS is based on a series of closely-linked modules which are solved simultaneously. The bilateral trade model is the heart of the system. This guarantees consistent linkage of trade volumes and prices for 25 commodities and a service sector. Exports of one country have to be imports of another country and so at the global level the trade system is closed.
Within each country, the economies are modelled using either a macro model (MM) or input-output model (IOM). The difference is the sectoral coverage, which is missing from the macro model; where possible the IOM is used but due to data limitations this is restricted to 21 countries.
The IO models describe the production technology in the countries as reflected in the input structures. Energy-emission models (EEM) are based on energy balances of the International Energy Agency and are available for all countries and regions distinguished in the model. In the EEM energy demand and supply are consistently linked for 12 energy carriers to the economic driving forces that are explained in the economic part of the model. Carbon emissions result from the use of fossil fuels.
Material inputs have also been integrated into the modelling system. For all countries resource-use extraction in tons is explained for six categories. Their development is either driven by economic activity or energy demand for fossil fuels.
