How can computable general equilibrium models serve low-carbon policy? A systematic review

Abstract Computable general equilibrium (CGE) models have been widely employed in economic, social, and environmental impact assessments for low-carbon policies. As net-zero transition has become a global trend, it is crucial to conduct systematic review of how CGE serve This examined 1002 studies published between 2001 2021, revealing the application policy analysis by researchers 51 countries, including United States, China, Western Europe, Japan, Australia, while Latin America, Central Asia Eastern Europe are limited. Climate targets, carbon pricing, energy main focuses analysis, land policy, demand-side actions, several other policies less studied. In addition, generally on economic impacts reduction, with growing amount attention social consequences. The structure, database, model coupling techniques becoming more complex order increasingly multifaceted diverse study purposes. provides comprehensive overview research trends policies, thus improving our understanding multiple impacts, models. We also identify gaps potential cutting-edge current research. Future work should improve capacity simulate actual ‘second-best’ provide feedback optimization, enhance dynamic mechanisms structural change.
