​Carbon footprint of water

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.
