The reference card is a clearly defined description of model features. The numerous options have been organized into a limited amount of default and model specific (non default) options. In addition some features are described by a short clarifying text.

AIM-CGE documentation consists of a referencecard and detailed model documentation

Model scope and methods

Model documentation: Model scope and methods - AIM-CGE


AIM/CGE is developed to analyse the climate mitigation and impact. The energy system is disaggregated to meet this objective in both of energy supply and demand sides. Agricultural sectors have also been disaggregated for the appropriate land use treatment. The model is designed to be flexible in its use for global analysis.


General Equilibrium with technology explicit modules in power sectors

Solution method

Solving a mixed complementarity problem

Socio economic drivers

Model documentation: Socio-economic drivers - AIM-CGE

Exogenous drivers

  • Exogenous GDP
  • Total Factor Productivity
  • Labour Productivity
  • Capital Technical progress
  • Energy Technical progress

  • GDP per capita

Note: GDP is endogenous, while TFP is exogenous; but TFP can be calibrated so as to reproduce an given GDP pathway.

Endogenous drivers

  • GDP


  • GDP per capita
  • Income distribution in a region
  • Urbanisation rate
