Water-stressed areas
Target: 20% reduction in water consumption by 2015 in water-stressed areas
The Group has 19 sites (excluding Grid) located in areas defined by the World Resources Institute as water-stressed, based on 2009 data. The measures put in place were so successful that our targets must be revised: a reduction of 39% has already been registered in these sites.

General water consumption
Even if the Group didn’t specify targets for all its sites, it systematically strives to limit water consumption. In 2010, water consumption from all sources (public network, ground water and surface water) globally decreased by about 30%.
More than 75% of the water used within the Group’s 198 units is consumed by around 20 units in permanent facilities. The top consumers are located in France, UK and India.
Water consumption in permanent facilities:

Waterborne discharges
The impact of the Group’s production facilities on the quality of the waters discharged is globally considered limited, although certain sites may at times be confronted with specific issues.
