This document provides an overview of a study mapping environmental and social risk due diligence practices in the financial sector. It finds that while many financial institutions conduct some level of environmental and social risk assessment, approaches vary depending on business models and services provided. The study aimed to better understand current due diligence processes and the level of influence financial institutions perceive they have over clients' environmental and social impacts. It involved surveys of over 50 financial institutions globally and interviews with 30 institutions. Key findings included that risk-based due diligence approaches differ based on transaction types, and leverage over clients depends on the nature of the financial relationship. The study seeks to inform dialogue on responsible business conduct expectations for the sector.
