Towards standardized adaptation modeling in CGE frameworks: Assessing sea level rise impacts and responses in Europe 1: Wegener Center for Climate and Global Change, University of Graz, Austria; 2: Euro-Mediterranean Center on Climate Change (CMCC), Venice, Italy; 3: International Institute for Applied Systems Analysis (IIASA), Laxenburg, Austria; 4: Institute of Economics, University of Graz, Austria; 5: Global Climate Forum (GCF); 6: Division of Resource Economics, Albrecht Daniel Thaer-Institute and Berlin Workshop in Institutional Analysis of Social-Ecological Systems (WINS), Humboldt-University, Berlin, Germany Climate change adaptation is increasingly assessed using computable general equilibrium (CGE) models, yet its representation remains fragmented and often ad hoc, limiting transparency and comparability across studies. This paper develops a generic, impact-agnostic framework for systematically translating adaptation measures from sectoral and biophysical models into CGE parameters. The framework is structured around five guiding questions that clarify adaptation objectives, mechanisms, implementing agents, economic incidence, and temporal dynamics. We demonstrate the framework through an intercomparison of two CGE models, COIN-INT and ICES-XPS, assessing sea level rise impacts and adaptation in Europe under the SSP2–RCP7.0 scenario. Using adaptation data from the DIVA coastal impact model, we evaluate three strategies: constant dike heights, constant protection levels, and cost-optimal protection. Results show that insufficient adaptation leads to increasing GDP losses over time, while stronger, cost-optimal protection substantially reduces long-term damages, nearly eliminating GDP losses by 2070 in most regions. Despite differences in impact magnitude due to structural model assumptions, both CGE models consistently rank adaptation strategies, underscoring the value of standardized adaptation modeling approaches. | |
