Tap water's carbon footprint revealed

Comments (1)

healthy_water2.jpgIn yesterday's Guardian a reader asked "Watching those pictures of water being pumped out of flood-stricken areas got me thinking: how much energy does it take to produce all our mains water?" It's a good question, and one that Leo Hickman answered after some serious calculations. Everyday in the UK we use 19 billion litres of tap water, and in one year the figure is seven cubic kilometres! Between 2% and 3% of the UK's electricity is used to process and 'deliver' this water to us in our homes, and this creates 0.5% of our carbon emissions. Hickman's conclusion was that a litre of water has a footprint of 0.298 grammes, and said "even if you had one very full bath - about 150 litres - every day for a year, overall it would represent just 15kg of greenhouse gas emissions. That's about what the average car produces over 80 kilometres."
