According to an AEW study, what is the climate risk premium?

The climate risk premium represents the additional return that investors expect for taking on the risks associated with climate change. In the context of the AEW study, a climate risk premium of 19.4 basis points per annum indicates that investors demand a slightly higher yield on investments that are subject to the uncertainties and potential costs associated with climate-related factors. This premium reflects investors' recognition of the potential impacts of climate change on asset values, including physical risks to properties and regulatory risks from changes in climate-related policies. Such premiums are important in guiding investment strategies and asset valuations as they account for the growing necessity to integrate climate risk considerations into financial assessments.
