Municipalities and Sovereign

Climate change’s macroeconomic impacts can affect muni and sovereign tax bases and revenue outlooks, with serious implications for bond buyers and rating agencies.

Four Twenty Seven’s physical climate risk scores measure relative exposure of U.S. cities and counties to cyclones, sea level rise, extreme rainfall, heat stress and drought.

Our country climate risk index combines climate hazard exposure data with economic and social information to depict nation-level vulnerabilities to climate impacts. Forthcoming analysis will incorporate assessments of sub-national administrative boundaries for all countries globally.

Leveraging big data analytics, our physical climate risk scores offer greater transparency for investors and credit rating agencies to understand local economic risk driven by climate impacts.
