Water is of course the second most basic requirement for survival after air. Many people now recognise that water scarcity is fast becoming an issue. Many fewer people realise that there is a carbon footprint associated even with this basic service. Here at Staffordshire University, we consume 142,000m3 of it every year. The carbon footprint associated with this is 57 tonnes per annum.
The emissions associated with water arise from energy consumed in its distribution and in the treatment before and after use. Water has often to make a long journey to get to your tap – maybe from a reservoir outside Manchester, when it then must travel 50 miles in a pipe and still have enough energy left to rise the height of a building to your flat.
Please be thoughtful in your use of water. The less you waste the less energy goes into water transport and also, the more there is to go round everywhere else.
