Aqueduct 3.0: Updated Decision-Relevant Global Water Risk Indicators

This technical note describes the Aqueduct 3.0 water risk framework, which aggregates 13 indicators—covering quantity, quality, and reputational risks—into a composite overall water risk score to help decision-makers identify high-risk regions or assets.

• The Aqueduct 3.0 framework combines 13 different water risk indicators, including those related to quality, quantity, and reputation, to create a composite overall water risk score designed as a communication tool for decision-makers.
• Aqueduct 3.0 utilizes a new hydrological model that provides higher spatial resolution, a monthly time series for specific indicators, and integrated modeling of surface water, groundwater, and water supply and demand.
• Because key elements like overall water risk cannot be directly measured or validated, the tool is intended for prioritization and should be supplemented with regional and local deep dives.
