Blue water consumption has been added as an inventory metric and is not included in scoring. Blue water consumption measures water consumed during the production process, including water that is incorporated into the product or evaporated as part of the production process. This includes net water use (water input minus water output) and does not include green water (rainwater) or gray water.
Water scarcity measures the potential of water deprivation, considering both water consumption and scarcity/region. The Higg MSI uses the AWARE method to analyze water scarcity. This is the new consensus method to measure water scarcity, recommended by the EU Joint Research Center and included in the EU Product Environmental Footprint (PEF) methodology. The AWARE metrics represent the relative Available WAterREmaining per area in a watershed after the demand of humans and aquatic ecosystems has been met. So, water used in more water-scarce areas is more impactful than water use in an area without water scarcity issues. For global processes where the specific manufacturing region is undefined, the Higg MSI uses the EF method global AWARE water scarcity factor.
