Water issues for a company
Water is a source of life for companies just as it is for living things. Its multiple uses put growing pressure on this resource. Causing part of this pressure, companies depend on water resources to run their operations. This dependence means that they have to identify, map and anticipate the risks linked to water scarcity and pollution and take a long range and global look at how they interact
with their environment their water footprint.

Measuring a company’s water footprint
Once the risks have been identified and prioritised, the actual water footprint can be assessed using indicators on the volumes used in the company’s business, and the resulting impact on water quality. So the right questions have to be asked on the scope to be used: what are we measuring? Should we take a sector-based approach or take into account the entire product life cycle? Finally, which indicator should be selected for use, among existing tools? As for all types of reporting, a good indicator must be credible and acknowledged, it must be possible to reproduce it over space and time and it should be founded on science.

Action and monitoring plan
Measuring the water footprint gives a company a clear view of their water management to implement appropriate actions. Reporting gives the chance to define precise objectives and action plans to reach them. The company local sites apply and then can adapt these guidelines to a local scale. The effectiveness of actions implemented at site level, when reported, allows, if necessary, to readjust the objectives, in a continuous progress path. Participants can be involved throughout the process to make sure that the work is moving in the right direction.

Emerging issues
The interdependence of water management with other environmental issues creates new challenges for companies, questioning assessment methods or in any case making them seem uncertain. The need to anticipate risks appears even clearer for companies when the issue becomes adapting their water management to changes caused by global climate change or new public health issues raised by micro-pollutants.
