The GARP Risk Institute (GRI) recently undertook a global, cross-sectoral survey of firms’ approaches to managing the financial risks associated with climate change. That survey indicated that climate risk management is generally in its infancy, but that firms want to learn and improve their practices. This paper provides a guide to the risk implications of climate change, starting with a brief overview of the current scientific and regulatory context, and then examining the financial risks for different types of financial institutions. It concludes with some practical next steps.
