Hoekstra’s 2016 suggestion in section 3.4 and Table 2 to consider a water footprint weighted in relation to water availability as opposed to water scarcity is, in all respects and purposes, still essentially a form of characterization to ensure comparability of the relative water use impacts in different locations.
Hidden water use The Water Footprint method shows the ´hidden water use´ of products. Hoekstra´s method to calculate the overall water use of a product, reveals that it takes an average 3,000 liters to produce one 200/gram steak, 3,400 liters for a 200/gram chocolate bar and 2,700 liters to produce the cotton needed to make a single t-shirt.
