ABSTRACT
This manual contains the global standard for the definition of water footprint terms and the method of water footprint assessment. The standard has been developed over the past two years in an open and transparent process facilitated by the Water Footprint Network. Through the involvement of a large variety of organizations around the world that thus far have been working with the water footprint concept, the standard has become a true globally shared standard. Having a unique and shared standard is increasingly important since communicating about water footprints and desired water footprint reductions will be seriously hampered if different stakeholders use different ways of defining and calculating water footprints.
