These Corporate Water Disclosure Guidelines emphasize that a company’s risks, opportunities, and impacts differ greatly depending on the river basin context(s) in which it operates. For example, a thousand gallons of water used in a water-rich region will likely have substantially less impact on ecosystems and people than a thousand gallons used in a water-scarce region. Thus, where possible, companies seek to report location-specific information in order to shed light on where water-related challenges are greatest and where action should be prioritized. However, in the past, there has been no common nomenclature for river basin names or delineations for their boundaries on a global scale. This means that, for example, two companies might report on their water use in the Yellow River Basin, but be referring to two different (albeit likely overlapping) geographic areas, thus leading to results that are confusing for, and of limited use, to stakeholders. Understanding this deficiency, as part of the development of these Guidelines, the CEO Water Mandate – in collaboration with World Resources Institute – has developed the Interactive Database of the World’s River Basins based on the most recent and publicly available information provided by HydroSHEDS, Global Runoff Data Centre, Watersheds of the World, Water Footprint Network, WRI Aqueduct, and other sources in the public domain. This database allows companies to enter the coordinates of their (and their suppliers’) operations and understand in what river basins they are located (using a newly developed common nomenclature) and the boundaries of those river basins. Alternatively, companies can use interactive maps to manually locate their facilities on a map and learn more about the river basins in which they are located. For interested companies, the newly developed common nomenclature will also be incorporated by CDP into their water questionnaire. The Interactive Database of the World’s River Basins is currently under construction.
