The IMF-World Bank Climate Policy Assessment Tool (CPAT) is designed to help governments design and implement effective climate mitigation policies. It assists in assessing the economic, environmental, fiscal, and social impacts by providing quantitative estimates of various policy effects. CPAT covers over 200 countries and allows for the rapid quantification of impacts on emissions, revenues, GDP, welfare, distribution of costs, household incidence, and co-benefits such as air quality and road safety improvements.

Key components include:

1. Mitigation Module: Estimates impacts of policies like carbon taxes, ETSs, fuel subsidy reforms, and renewables subsidies on energy, emissions, revenues, GDP, and welfare, considering both direct and indirect effects.
2. Distribution Module: Assesses the impacts of energy price changes on industries and households, moving toward a user-friendly cost-push microsimulation approach.
3. Co-benefits Modules: Measures health benefits via reductions in local air pollution and traffic accidents connected to policies like carbon pricing.

CPAT supports policymakers in identifying design weaknesses in mitigation strategies, ensuring the policy framework is effective and equitable. It also emphasizes integrating distributional impacts to enhance public acceptability and social welfare, facilitating a "just transition."

This tool contributes to global climate policy analysis by enabling transparent, consistent, and comprehensive comparisons across countries, from developed to developing nations, thereby aiding in the global effort to limit warming.
