CoffeeGlobal average water footprint: 140 litres for 1 cup of coffee. It costs about 21000 litres of water to produce 1 kg of roasted coffee. For a standard cup of coffee we require 7 gram of roasted coffee, so that a cup of coffee costs 140 litres of water. Assuming that a standard cup of coffee is 125 ml, we thus need more than 1100 drops of water for producing one drop of coffee. Drinking tea instead of coffee would save a lot of water. For a standard cup of tea of 250 ml we require 30 litres of water. The world population requires about 120 billion cubic metres of water per year in order to be able to drink coffee. This is equivalent to 1.5 times the annual Rhine runoff and constitutes 2 % of the global water use for crop production. International trade in coffee products is responsible for 80 billion cubic meters of virtual water exports, which is about 6% of the international virtual water flows in the world. Among all the crop and livestock products coffee stands at the top position in the list of global virtual water flows. The water needed to have the Dutch drink coffee |
