Environmental indicators for our production operations

The environmental indicators for our production operations are based on the indicators of the European Chemical Industry Council (CEFIC). In our sustainability reporting, we show the progress of each of our indicators over a five-year period. The production-related data for 2011 were determined at 171 of 180 Henkel sites in 56 countries. The data represent more than 95 percent of our worldwide production volume in 2011. They are validated centrally for year-end reporting and also verified locally within the framework of our international audit program Any differences in data discovered or reported at a later date are corrected retroactively in our reporting system. Since our production structures are constantly changing – as a result of acquisitions or site closures, for example – the number of sites contributing data changes accordingly: from 166 in 2007 to 171 in 2011. To ensure the comparability of the annual data, we also show their progress as an index relative to the volume of production.

Index: The index in the tables shows the progress of the specific indicators relative to the volume of production (per metric ton of output). The base for the index is the year 2007 (= 100 percent).

Production volumes

   
In thousand metric tons
  2007 2008 2009 2010 2011
Production volumes 7,366 7,707 6,853 7,481 7,550
Index: Change from 2007 to 2011 +2 %
Due to the improved economic situation and increasing global demand, our production volumes have been rising again since 2010.

Emissions of volatile organic compounds

  Symbol
In metric tons
  2007 2008 2009 2010 2011
Emissions of volatile organic compounds 473 430 308 367 326
Index: Change from 2007 to 2011 –33 %
Since 2007, additional measures have been implemented to reduce emissions of volatile organic compounds. The rise in 2010 is due to the increase in production volume and shifts in the production portfolio.

Water consumption and volume of wastewater

  Symbol
In thousand cubic meters
  2007 2008 2009 2010 2011
Water consumption 11,598 12,041 9,174 8,688 7,921
Volume of wastewater 5,473 6,010 4,578 4,045 3,664
Index: Change
from 2007 to 2011
Water consumption –33 %
Volume of wastewater –35 %
Because water is lost by evaporation and water is contained in many of our products, the volume of wastewater is smaller than the volume of water consumed.
