"An Integrated Modelling Approach to Assess the Impact of Existing Structural Policies: The Case of Switzerland’s Climate and Energy Policies" Authors: Lutz, Luisa, Jean Chateau, Jules Schers, Luca Sebastianelli and Evangelos Panos Abstract As countries continue to implement climate and energy policies, there is a growing need for modelling frameworks capable of evaluating the actual performance of implemented policies rather than hypothetical future scenarios. This study introduces a novel harmonised soft-linking approach that combines the detailed technological representation of bottom-up models with the macroeconomic consistency of CGE models to assess the environmental and economic impacts of current policies. It also presents a case study that applies this approach to evaluate Switzerland’s current climate and energy policy mix, integrating the JRC-EU-TIMES energy system model with the OECD ENV-Linkages global CGE model. Through coordinated counterfactual scenarios, the paper examines the Swiss ETS, the CO2 levy, transport-sector standards and taxes, and building-sector instruments. Results indicate that existing policies reduce cumulative CO2 emissions between 2023 and 2035 by roughly 1–7%, with carbon pricing delivering the strongest near-term abatement. The findings also underscore the value of transparent, scalable soft-linking architectures for policy evaluation and highlight key methodological considerations when integrating bottom-up and top-down models in policy analysis. |
