Like most British people, I enjoy a nice cup of tea. And like most practitioners of life cycle assessment (a far smaller group), I’m very interested in understanding the full impact of the products I consume.So how much water goes into a cup of tea? Somewhere around 30 litres of water is required for tea itself, 10 litres for a small dash of milk and a further 6 litres for each teaspoon of sugar. This means that a simple cup of tea with milk and two sugars could actually require 52 litres of water – enough to fill my kettle more than 30 times.
