The IMF-World Bank Climate Policy Assessment Tool (CPAT) is a model designed to help countries mitigate climate change. The tool is available on the IMF and World Bank websites, and gaining access for governments is outlined on the accompanying webpages. The authors would like to thank the current and former members of the joint CPAT team for their partnership and collaboration, as well as several internal and external contributors. The authors are grateful to James Roaf, Dora Benedek, and numerous IMF colleagues for comments, and to Hope Samiee and Monique Valle for research assistance.
