Water Footprint

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.

  • Analyzes risks of water consumption in the future.
  • Analyzes water-related risks in the supply chain.
  • Enhances the environment-friendly image of companies.
  • Determines methods for decreasing environmental impacts of water consumption.
  • Improves environmental sensibility.

Blue, Green, and Greywater footprints are an indicator of the usage and quality of water.

  •  Blue Water: Total volume of groundwater and surface water that is needed for the production of a material. Freshwater.
  • Green Water: Total rainwater amount used for the production of a material. In this water footprint, rainwater does not get lost or contribute to groundwater. It hides under the soil or on the soil for a while. Green water is affected by rain so climate should be considered while evaluating the green water requirement of an area.
  • Grey Water: Grey water is domestic wastewater. Grey water footprint indicates pollution. It indicates the freshwater amount that is used for disposal or reduction of this pollution load. That’s why it is considered with the increase in population and industrial growth.

  • First of all, problems with water resources should be analyzed in terms of economic, social, and environmental.
  • Water amount, its effect, and risk should be determined during supply chains.
  • Water footprint should be calculated and action should be taken to minimize effects in areas that have or can have water scarcity.
  • International conventions should be supported that guarantee access to water.
  • In addition to minimizing its own water footprint, it is important to make collaborative work with verifiers, other companies, and academics about sustainable water resources.
