Virtual Water
Water consumed/polluted along supply chains of products, organization or nations:
• Blue water: ground and surface water
Blue water consumption: “Loss” of blue water from theoriginating river basin due to evapotranspiration,product integration or discharge in other basins or the sea
• Green water: rain water
Green water consumption: “Loss” of green waterdue to evapotranspiration of rainwater by plants
• Gray water: polluted blue water
Gray water footprint: water polluted by wastewater,measured by the volume of water required to dilutewastewater until quality standards are reached
