Treading lightly or not:Water footprints - improving business water use

摘要

The water footprint concept has gained a global foothold since its introduction a decade ago. These days it is not uncommon for people to know exactly how much water it takes to produce a glass of red wine (about 120 I), a kilogram of rice (2 500 I) or even an average-sized pizza (1 260 I).But what is the water footprint and how does it work? The WRC has just released a new report on water footprints, that should hopefully provide food for thought for all industries. The so-called water footprint concept, first introduced in the Netherlands in 2002, is now used internationally to create awareness around the water consumption and pollution of consumer products, within catchments and even countries.
