Intertemporal Computable Equilibrium System (ICES) Global CGE Model

ICES is a recursive dynamic multiregional computable general equilibrium (CGE) model for the economic assessment of climate change impacts and policies. The model’s general-equilibrium structure allows for the analysis of market flows within a single economy and international flows with the rest of the world. The model is flexible in regional aggregation and time horizon up to 2070. Different versions of the model have been developed to enable specific analyses: ICES offers a comprehensive assessment of current well-being and future sustainability based on 28 indicators related to the 17 Sustainable Development Goals (SDGs). A subnational model version considering 125 subnational regions in the European Union plus the United Kingdom enables the study of regional specificities in climate change impacts and policies. A version with an advanced description of the public sector has been developed to investigate fiscal implications.

The ICES model is being developed and maintained by the RFF-CMCC European Institute on Economics and the Environment.
