This report outlines a sensible business approach to analyzing and adapting to the physical risks of climate change. It focuses on a critical first step in assessing these climate impacts: understanding the potential risks to business and the importance of taking action to mitigate those risks. Not all businesses need to take action now; this paper develops a qualitative screening process to assess whether a business is likely to be vulnerable to the physical risks associated with climate change, and whether a more detailed risk assessment is warranted.
