More information about these indices. Select date: Part of this task involves developing global water quality indicators and ultimately, a global water quality index. UNEP delegated this responsibility to its GEMS/Water Programme, with direction to convene an international experts’ workshop designed to implement the indicators and index requirements. The experts’ recommendation report is available on the GEMS/Water website. This report presents the results of implementing the experts’ first recommendation. It outlines an approach taken to develop a global water quality index, as well as preliminary sensitivity analysis and validation of the index against real water quality data. Two measures of air and water quality – the number of days with an air quality index above a healthy threshold and the number of violation points against drinking water systems in each state – account for half of the weight in the Best States for natural environment ranking.

The source for water quality data used to analyze and validate the index calculations is GEMStat, the online global database of water quality for inland waters maintained by GEMS/Water.

An increasing number of companies are waking up to the importance of water security, and CDP's 2017 Global Water Report shows a 193% increase in businesses leading the way on water stewardship. A water-secure world is possible, and the transition is underway. Water quality is addressed also under other SDGs such as the goals on health, poverty reduction, ecosystems and sustainable consumption and production, recognizing the links between water quality and the key environmental, socioeconomic and development issues (Goals 1, 3, 12, 15 and Targets 1.4, 3.3, 3.9, 12.4, 15.1).
