As Criterion has written, gender-based violence poses multiple risks—operational, regulatory, reputational, and political—to investments of all types. GBV is complex and investors often cite a lack of clarity about what data exist and how to use those data in their work. This brand-new GBV Risk Score tool provides a solution. The tool is dynamic, powered by real-time data on GBV from a multitude of sources. It enables financing institutions and governments to understand the materiality of GBV to their investments, including the level and types of GBV risk in any given country. The accompanying methodology laid out in this paper helps users understand the severity and potential consequences of the risk and offers advice on risk mitigation, harm reduction, and proactive strategies to address GBV.
