The Water Footprint Assessment Tool is a free online web application that provides clear insight into how water is appropriated for human uses and the impacts resulting from those uses.

It assists companies, governments, NGOs, investors, consultants, researchers and others to calculate and map the water footprint, assess its sustainability and identify strategic actions to improve the sustainability, efficiency and equitability of water use.

The Water Footprint Assessment Tool is being developed by the Water Footprint Network, in collaboration with Water Footprint Implementation. Bringing together the internationally recognized Global Water Footprint Standard and the most comprehensive, global water footprint database – WaterStat – as well as user-provided data, the Water Footprint Assessment Tool allows you to complete either a geographic or production assessment and provides results based on sound methods and best available data.

The geographic assessment allows you to:

The production assessment allows you to:

The Water Footprint Assessment Tool is in continuous development as research is completed and new data are available and to better serve the full range of users who can benefit from the tool. We hugely appreciate your feedback on the tool. Contact us here.

This latest version of the Water Footprint Assessment Tool is developed by the Water Footprint Network and Water Footprint Implementation, under the leadership of Michiel van Heek.

It may surprise you how much water is used to produce the food you eat, your clothing and other products. Use the Product Gallery to find out the volume of water consumed to produce the goods we rely on everyday. These values are based on global averages over a 10-year period, which means the same product will have a different water footprint depending on where, when and how it was produced.

The Product Gallery helps you learn about which products are more water intensive, which are less and how polluting their production is.

When considering the water footprint of a particular country, we can consider both the water footprint of production and of consumption. To learn about the water footprint of all the products consumed by the people living in a country have a look at the National Water Footprint Explorer.

The water footprint of national consumption is the total amount of fresh water that is used to produce the goods and services consumed by the inhabitants of the nation. It includes two components: the part of the footprint that falls inside the country (internal water footprint) and the part of the water footprint that falls in other countries (external water footprint). To get an idea of the water footprint of consumption for your country or others, go the National Water Footprint Explorer.

To learn about the water footprint of production for your country or others, go to the Water Footprint Assessment tool. To calculate your own personal water footprint (of consumption) try the Personal Water Footprint Calculator.
