The exposure of European Union sovereigns to climate risks can be acute, from extreme weather, or chronic, from the productivity effects of gradual temperature increase, increased sea levels and the transition to a low-carbon economy that results in repricing of assets. Climate-related innovations can also spur growth. These risks are priced by investors and can affect sovereign credit ratings.

Governments and fiscal stability authorities have an interest in the sovereign-debt implications of climate change being transparent. To this end, we look at the exposure of EU sovereigns to climate risks, study international best practices, and describe the transmission channels from climate change to public finance.
