As a company providing expertise and tailored combinations of chemicals for water-intensive industries, our own corporate responsibility program inevitably addresses water efficiency in our own manufacturing processes.
In Kemira’s manufacturing, water is used mainly for cooling or as process water. Many of our sites collect rainwater, and for example recycle the used water back in the same process or reuse it in another facility.
In 2013 we started a project to assess opportunities for water efficiency improvement in our own operations. Our target is to understand and evaluate the water related risks and opportunities in our own manufacturing operations, and to develop a water management program by the end of 2014. This year we have focused on collecting detailed data on how water is used and analyzing opportunities for improvement. Based on the assessment results, key performance indicators for water efficiency will be defined during 2014.

|1 The reduction from 2010 to 2011 is partly caused by over-reported figures in previous years.|
|The calculations have been made according to GRI G4 reporting guidelines. The figures presented are based on data collected from Kemira's sites. Data covers all of Kemira's production sites according to Kemira consolidation rules.See also the graph Water balance and the table Summary of water indicators in the section of Responsible manufacturing; Water efficiency|
