00:00What is a water footprint?

00:07It's all the fresh water we use, not just in drinks and showers, but in everything we consume.

00:14We use water to make food, clothes, cars and more.

00:19One cotton t-shirt takes 2,700 liters.

00:23A kilogram of beef uses 15,000 liters.

00:27And a kilogram of chocolate takes more than 17,000 liters.

00:32Some industries consume more water than others.

00:35Agriculture has the highest water footprint.

00:38We use water to grow crops, many of which are then used to feed livestock,

00:43plus drinking water for animals, processing and packaging.

00:48Energy production is also highly intensive.

00:51Water is used for cooling in power plants, biofuel plants and in hydroelectric power.

00:57Growing cotton and dyeing fabric use immense quantities of water too.

01:02And technology, like smartphones and data centers, also have high water footprints.

01:08The EU has two corporate sustainability directives,

01:11which oblige companies to address their environmental impact,

01:15including their water footprint,

01:17and lessen any negative effects like excessive water use or damage to ecosystems.
