The Climate Risk Sensitivity Assessment Tool was developed to help Brazilian banks identify the sensitivity of their credit portfolio to climate risks. The tool uses as reference concepts of Resolution nº 4327 (relevance and proportionality) and TCFD (critical sectors), with the degree of exposure to climate risk of bank operations (relevance) and the complexity of banks addressing exposure to climate risk (proportionality). Portfolio valuation through the tool can take place at three levels: consolidated portfolio, sectoral portfolio and clients, identifying exposure to critical sectors and the result of this analysis can be used for monitoring and prioritization of actions. This report was developed in partnership with SITAWI Finance for Good and with the support of a group of FEBRABAN member banks.
