Water footprint determines the total clean water amount used in the production and consumption activities of a product and also the pollution rate. It refers to the measurement of the amount of freshwater used (including evaporation) in the entire supply chain to produce a product or service, covering the entire process from raw material processing to direct operations and consumer use of the product.
Water footprint can be calculated for an establishment, product, service, individual, or society. It uses both direct water usage and indirect water usage caused by the production process. Water footprint calculations are made according to ISO 14046 standards. This standard is an international standard that describes water footprint assessment and reporting principles. It is applied to products, methods, and individuals based on their life cycle assessments.
Blue, Green, and Greywater footprints are an indicator of the usage and quality of water.
