### Summary
- To stabilize the climate, global greenhouse gas emissions must be cut by 25 to 50 percent by 2030 compared to 2019.
- The unprecedented rate of decarbonization requires climate mitigation policies across countries, notably: carbon pricing, fossil fuel subsidy reform, renewable subsidies, feebates, emission rate regulations, and public investments.
- The IMF and World Bank are making their joint Climate Policy Assessment Tool (CPAT) available to governments as a transparent, flexible, and user-friendly model covering over 200 countries.
- This paper describes the CPAT model, its data sources, key assumptions, and caveats.

### CPAT model features
- Coverage: over 200 countries.
- Design priorities: transparency, flexibility, user-friendliness, and rapid quantification of policy impacts.
- Policy instruments modeled explicitly: carbon pricing, fossil fuel subsidy reform, renewable subsidies, feebates, emission rate regulations, and public investments.

### Metrics and impacts CPAT quantifies
- Energy demand
- Energy prices
- Emissions
- Revenues
- Welfare
- GDP
- Household impacts
- Industry impacts
- Local air pollution and health
- Many other metrics relevant to economic, environmental, fiscal, and social impacts

### Applications and policy relevance
- Supports design and implementation of effective, efficient, and equitable climate mitigation policies.
- Enables governments to assess trade-offs across economic, environmental, fiscal, and social objectives.
- Facilitates rapid scenario analysis for different instrument mixes and country contexts.

### Data sources, key assumptions, and caveats
- The paper describes CPAT’s data sources.
- The paper describes CPAT’s key assumptions.
- The paper describes caveats associated with model use and interpretation.
