There’s a lot of smoke and mirrors out there around this subject, so let us tell you as simply as possible what we are doing without all the charts, graphs and pictures of forests and animals

Coffee is a thirsty old thing compared with tea.

Producing a single cup of coffee requires 136 litres of water - more than five times the amount needed to produce a cup of tea. The difference is mainly due to the quantities of water needed to grow the crops, but coffee's footprint also includes the water used to soak the beans in order to remove a gelatinous outer layer. We found this out from the good people at Friends of the Earth, who put together a report which estimates how much land and water are used in the production of everyday goods.
