The delivery of 1 litre of tap water creates 0.25g of CO₂.
Bottled water produces around 250g of CO₂ (including production and the bottle).If the world consumes 200 billion litres of water per year that’s 80 million tonnes of greenhouse gases, or one sixth of 1% of global emissions.The table below shows how CO₂ emissions for producing drinking water are reducing, but for treating wastewater are increasing.
|Carbon impact of delivering customer service (Thames Water)||2012/13||2013/14|
|Water service - kg of CO₂ equivalent emissions per cubic metre of treated potable (drinking) water.||293.2kg||270.9kg|
|Wastewater Service - kg of CO₂ equivalent emissions per cubic metre of treated wastewater.||266.1kg||272.5kg|
