The objective of this report is to assess the feasibility of valuing water as a natural capital asset in at least 150 countries for possible inclusion in CWON. Water represents a portfolio of assets, including surface water, groundwater, and soil water (“green” water). Recycled water (“gray” water) is not considered a water asset as it is derived from water extracted from the environment and circulates within the economy. Ocean water is not considered an asset needing valuation as it is essentially limitless and industrial processes are needed to make it suitable for most uses (for example, desalination for drinking water and pumping for cooling). The report identified three approaches for estimating values consistent with the value of the other natural capital assets in CWON: (1) asset-by-asset, (2) use-byuse, and (3) service-by-service.
