The book presents a structured discussion of measuring the key economic and financial dimensions of climate change. It combines economic theory and analysis with real world examples of how climate data can be constructed for different country settings, based on existing climate science and economic data. The book will serve as a reference point for the IMF’s Climate Change Indicators Dashboard (CID). A guiding principle of the book is that there are important climate data gaps, but also practical and innovative approaches to close many of them. The book discusses how to track greenhouse gas emissions by production and consumption (Chapters 1-2), which lead to physical risks (Chapters 3-4) and transition risks (Chapters 5-7) and conclude with cross-border dimensions of climate risks (Chapters 8-9).
