Performance Overview

Water

Key performance indicatorSTEV56; §2.2 Decalogue

This is an area where we are making good progress. We have consistently exceeded our Decalogue target, reducing our water consumption by unit of production by an average of about 10% rather than 5% per year. In 2005, our front-end sites reduced water consumption per production unit by 5.2% versus 2004, while back-end sites reduced consumption by over 7.2% over the same period. The net increase in water consumption is explained by our increased production.

EN5: Reductions in water consumption: absolute values 1,000 m3
  2000 2001 2002 2003 2004 2005
Total water use 18,630 20,330 19,450 19,850 20,550 21,834

See the Environmental costs versus savings table for details of the cost savings resulting from reduction of water consumption.

The chart below plots our performance against the Decalogue target (reduction of 5% per year), and shows that the reduction of water consumption per unit produced has been much faster than planned.
