It may not come as a surprise but scientists have crunched the numbers to find out the true environmental cost of bottled water.
Tap water is thousands of times better for the environment than bottled water, according to scientists. In fact, it takes three times as much water to produce a plastic bottle as it can hold.
This might not come as a surprise but researchers at the Barcelona Institute for Global Health (ISGlobal) have crunched the numbers to work out just how much better it actually is.
The research focused on Barcelona, Spain which is home to around 1.35 million people – nearly 60 per cent of whom consume bottled water at least some of the time.
They used something called a “life cycle assessment” which estimates the environmental impact of an item over its entire lifespan. That includes the extraction of raw materials, manufacturing, transportation, distribution, use and disposal.
