Stavros Zenios presents his latest paper "The risks from climate change to sovereign debt in Europe".

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. We argue for the adoption of an architecture of narrative climate scenarios, to guide national policymaking, so that European Union institutions and national fiscal authorities can mainstream climate risk analysis in public finance. Narrative Scenarios can be generated using integrated assessment models. As an illustration, we apply two prominent models to generate rough bounds on the extent of the risk for Italian debt from climate change. This raises issues about the models used. Coordination by EU institutions to develop regional scenarios will ensure acceptability, raise ambitions in dealing with climate risks and encourage the fiscal authorities to think of solutions. A network for climate-proofing public finance will bring together EU and member-state institutions, and we recommend budgeting for climate expenditures and contingent liabilities, and using risk-sharing instruments, with disclosure of the risks to public finance from climate change.

CefES and the European Commission – Joint Research Centre are proud to carry on this initiative with the aim of connecting scholars working on European issues all over the world and to strengthen their cooperation, particularly in this period of high human, social, economic and political distress.
