Your carbon footprint with a pint of tap water as against the bottled alternative is shocking!
Mike Berners-Lee in his book How Bad Are Bananas The Carbon Footprint of Everything tells us that a pint of tap water equals 0.14 g. CO2e and 14 kg CO2e a year’s tap water for a typical UK citizen.
A year’s supply for one person is the same as a 20-mile drive in an average car. That includes drinking, washing, cleaning- the lot.
Unlike the bottled alternative, which has around 1000 times the impact cold tap water is not a major carbon concern.
