Water footprint statistics (WaterStat)

Water footprint statistics have many uses – in Water Footprint Assessment studies, awareness raising and research projects, to inform public policies or company business strategies. Having water footprint statistics that are all formulated with the same methodology – the Global Water Footprint Standard – and therefore are comparable and can be used to tell the complex story of water is critically important and valuable to advancing the application of Water Footprint Assessment. To ensure that scientifically rigorous water footprint statistics are available for everyone to use, the Water Footprint Network develops and maintains WaterStat, the world’s most comprehensive water footprint database.

WaterStat currently includes five datasets:

1) Product water footprint statistics

2) National water footprint statistics

3) International virtual water flow statistics

4) Water scarcity statistics

5) Water pollution level statistics



All data included in WaterStat comes from peer-reviewed research. Additional water data will be added as they become available.

All datasets are published under Creative Commons BY-SA license. When referring to this WaterStat database, please cite as follows: WaterStat, Water Footprint Network, Enschede, the Netherlands. When using specific data refer to the original source as indicated for each separate dataset.
