Water footprint is a novel indicator of freshwater use, which quantifies the volume of water required by a product, service or activity when and where it is consumed. It includes both direct and indirect freshwater consumption. It also provides information on sustainability, by comparing the Water Footprint value with the availability and quality of water resource in situ. The final aim is to manage an improvement strategy designed to minimize the impacts related to this Water Footprint value. The three colours of water: • Green water. Rainwater, stored in soil as humidity, removed by plants in evapotranspiration processes. It is the main component in agrifood industries. • Blue water. Water volume that depends on a more or less complex infrastructure for its use. Its origin may be surface or subterranean. The traditional indicators for water use have focused on this component. • Grey water. Water volume that is required to buffer the concentration of pollutants that are spread in the environment. It depends on the quantity and quality of the spill, the essential quality of the receiving environment and the standards that are used to assess the environmental quality. Water footprint can be assessed in multiple scopes or levels (process, product, consumer, producer, business) by considering both direct and indirect impacts over the whole life cycle. Nowadays it is possible to achieve Water Footprint certification by implementing one of these two international standards: • WATER FOOTPRINT NETWORK – Water footprint assessment manual • ISO 14046 – Water footprint – Principles, requirements and guidelines
