Water is a scarce resource and in certain activities and areas of the world water shortages pose a threat. For this reason, there is increasing awareness of the need to improve water management. The verification of the Water Footprint by an independent third party, in accordance with globally accepted benchmarks, allows for the accurate calculation of how much water is needed to produce a product or provide a service, ensuring that the information is exact, coherent and transparent.
The Water Footprint is a global indicator of the appropriation of fresh water resources. For products, a water footprint is defined as the volume of water consumed both directly during the manufacturing process and indirectly throughout the supply chain. In order to manage water correctly, it must be known exactly how much water is needed to manufacture a product, provide a service or for an organisation to perform an activity.
There are different reference schemes for calculating and managing the Water Footprint (ISO14046, Water Footprint Network, etc). The first of these schemes focuses on measuring the amount of water consumed, while the second assesses the associated environmental impacts. Both the above schemes focus on analysing life cycles. The objective of verifying water footprints is to provide interested parties with a professional and independent opinion on the information and data obtained under the chosen scheme.
Water footprints apply to products, services, organisations, buildings and events. They are particularly important for the food and agriculture sector and others whose activities place a heavy demand on water resources.
AENOR offers this verification service, which can be integrated into a voluntary verification scheme in accordance with UNE-ISO
14046 and the Water Footprint Network benchmark. The verification activity can also coincide with carbon footprint verifications or Environmental Product Declarations (EPD), as well as audits on environmental management systems
ISO 14001 or quality management systems
Irrespective of the scheme employed, a water footprint assessment can be used to help perform studies on the risks associated with the strategic use of water with a view to reducing consumption, impact and disputes arising from water use. Enabling water to be used efficiently and optimising water management as regards products, processes and organisation. Providing consistent and reliable information based on scientific evidence in order to issue a water footprint report.
AENOR supports the actions performed by organisations with respect to calculating, reducing and offsetting water use.
If the results of the verification are satisfactory, the organisation will obtain the status:
AENORCalculated Water Footprint Status
AENORVerified Water Footprint Status
AENOR has granted Estrella Levante a water footprint verification certificate of conformity through the Water Footprint Network for its brewery in Murcia.
