Virtual Water: is the amount of water needed to make a product from start to finish. Virtual water is usually divided into three categories; blue, green and grey. Blue water is the water contained in rivers, lakes and aquifers and is the water processed by water companies to supply commercial demand, like food processing. Green water is the water supplied by precipitation and found in soils (soil moisture), so linked to agriculture. Grey water is the waste water from commercial activities and may be contaminated, it can also include the amount of water needed to dilute the contaminates.

Fact: It takes around 1800 litres of water to make one cotton shirt; how many school shirts do you have?
