CEPAM: Mapping Energy Technology and Environmental Regulation: A Multisectoral Climate and Energy Policy Assessment Model, for European Commission, DG JRC
The objective of this project was to provide IPTS with a powerful and transparent model system that accommodates rigorous and comprehensive quantitative assessment of the economic impacts induced by energy, technology and climate policies. The project has been built on the existing large-scale, multi-sector, multi-region computable general equilibrium (CGE) model GEM-E3-World that has been successfully used for environmental and energy policy analysis at the EU and world level. GEM-E3-World has been adapted to meet the IPTS needs with respect to the comprehensive analysis of climate and energy policy issues paying particular attention to flexible problem-driven spatial, sectoral and temporal resolution. The model system has been set up to allow for a flexible dis-aggregation of sectors and regions (including groups of EU candidate countries) as well as the choice of mid-/long-term model horizons. Adjustments to the existing GEM-E3-World model included (i) implementation of the GEM-E3-World core module within the user-friendly meta-language GAMS/MPSGE, (ii) regional coverage to include as detailed as possible the Eastern European country groups, (iii) the appropriate update of the environmental module with respect to external costs (damage functions) and non-CO2-GHG coefficients for production and consumption activities (iv) aggregation routines for flexible regional and sectoral dis-aggregation, (v) transition from a dynamic-recursive set-up with myopic expectation towards a fully intertemporal model version with rational expectations including the baseline definition, and (vi) provision of a visual interface for user-friendly (non-technical) scenario definition, analysis and management.
