WFN launches upgraded Water Footprint Assessment Tool to help solve global water problems

WFN is pleased to announce that the new, improved version 1.1 of our Water Footprint Assessment Tool is now live and available for everyone to use on www.waterfootprint.org/tool. This upgraded version is a major improvement over its predecessor and we hope it will further support your efforts to quantify your water use, assess its sustainability and prioritise where to reduce your water footprint and make it more sustainable. For more information please download the briefing paper or the full press release.

New article ‘Humanity’s unsustainable environmental footprint’, published in Science

Humanity’s environmental footprint must be assessed holistically and capped for us to live sustainably, says founder of the Water Footprint Network, Prof. Arjen Y. Hoekstra in an article just published in 'Science' today. For more information please download the article. or download the full press release.

Businesses and governments must tackle energy and water use in tandem

Businesses and governments must tackle energy and water use in tandem or risk major disruption, according to ground-breaking research released by sustainability specialists Anthesis in association with the Water Footprint Network. The white paper ‘Energising the drops: Towards a Holistic Approach to Carbon and Water Footprint Assessments’ provides the first ever guidance for governments and businesses on how to manage their climate and water impacts simultaneously, both locally and globally. For more information please download the report. or download the full press release.

The Water Footprint Assessment Manual

The Global Water Footprint Standard – developed through a joint effort of the Water Footprint Network, its partners, and scientists of the University of Twente in the Netherlands – has garnered international support from major companies, policymakers, NGOs and scientists as an important step toward solving the world’s ever increasing water problems. The standard is contained in the Water Footprint Assessment Manual.

Definition

The Water Footprint of a product is the volume of freshwater appropriated to produce the product, taking into account the volumes of water consumed and polluted in the different steps of the supply chain.

Direct and indirect water use

People use lots of water for drinking, cooking and washing, but even more for producing things such as food, paper, cotton clothes, etc. The water footprint is an indicator of water use that looks at both direct and indirect water use of a consumer or producer. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business.

The relation between consumption and water use

"The interest in the water footprint is rooted in the recognition that human impacts on freshwater systems can ultimately be linked to human consumption, and that issues like water shortages and pollution can be better understood and addressed by considering production and supply chains as a whole," says Professor Arjen Y. Hoekstra, creator of the water footprint concept. "Water problems are often closely tied to the structure of the global economy. Many countries have significantly externalised their water footprint, importing water-intensive goods from elsewhere. This puts pressure on the water resources in the exporting regions, where too often mechanisms for wise water governance and conservation are lacking. Not only governments, but also consumers, businesses and civil society communities can play a role in achieving a better management of water resources."

Some facts and figures

  • The production of one kilogram of beef requires 15 thousand litres of water (93% green, 4% blue, 3% grey water footprint). There is a huge variation around this global average. The precise footprint of a piece of beef depends on factors such as the type of production system and the composition and origin of the feed of the cow. [download report]

  • The water footprint of a 150-gram soy burger produced in the Netherlands is about 160 litres. A beef burger from the same country costs about 1000 litres. [download report]

  • The water footprint of Chinese consumption is about 1070 cubic meter per year per capita. About 10% of the Chinese water footprint falls outside China. [download report]

  • Japan with a footprint of 1380 cubic meter per year per capita, has about 77% of its total water footprint outside the borders of the country. [download report]

  • The water footprint of US citizens is 2840 cubic meter per year per capita. About 20% of this water footprint is external. The largest external water footprint of US consumption lies in the Yangtze river basin, China. [download report]

  • The global water footprint in the period 1996-2005 was 9087 Gm3/yr (74% green, 11% blue, 15% grey). Agricultural production contributes 92% to this total footprint. [download report]

  • Water scarcity affects over 2.7 billion people for at least one month each year. [download report]
