Energy efficiency & climate change
Striving for energy efficiency in manufacturing offers both environmental and economic benefits by reducing emissions and lowering manufacturing costs. We initiated an Energy Efficiency Enhancement E3 program in 2010 for identification and implementation of energy reduction potential at manufacturing sites.
The potential energy efficiency projects were identified by conducting regular energy audits at manufacturing sites. The manufacturing sites representing 94% of our energy use have now been audited. In 2013, the focus has been on the implementation of improvement projects, and in conducting follow-up audits. Total of 388 improvement projects have now been completed at 26 sites, generating annually 174,000 MWh energy reductions and EUR 7 million cost savings since 2010. Six sites have now completed all of the identified improvement projects.
Choices for energy efficiency improvement may include simple adjustments in operating methods, increased process efficiency, or more advanced solutions, such as utilizing waste heat in the local communities nearby Kemira’s operations. As an example, in the Rotterdam site in the Netherlands, introduction of variable speed drives was a significant energy efficiency driver, and in the Krems site in Austria, optimization of steam usage generated considerable energy reductions. Follow-up audits at manufacturing sites have generated a collection of best practices which will be used across the organization where applicable.
Energy Efficiency Index tool defined to measure progress
In 2013 we have defined the Kemira Energy Efficiency Index (EEI) to measure the company’s energy efficiency in manufacturing operations. The Energy Efficiency Index is the sum of site specific measures. The index is calculated individually for major sites that cover > 90% of Kemira’s total energy use, and site specific indexes are consolidated to form the Kemira EEI Index. The index is not dependent on the impact of changes in the production mix and volumes. The index enables us to monitor energy efficiency from the consolidated perspective as well as locally at each site, reflecting on the actual improvements we have achieved.

|1 The amount of energy Kemira uses through the purchase of electricity, steam and heat. Energy delivered off-site is included.|
|2 Kemira has calculated the energy intensity by dividing total energy consumption with the annual production volume. The total energy consumption includes fuel used for energy, electricity, heating, cooling and steam.|
|3 The types of energy included in the reductions include; fuel used for energy, electricity, heating, cooling and steam. The basis for the energy reduction is energy compumption in one year period.|
|The calculations have been made according to GRI G4 reporting guidelines. The source for conversion factors used is the International Energy Agency (IEA). Where specific information has not been publishded on production efficiencies by energy source, expert estimates have been made based on historical data.|
Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions. The 5th report of The Intergovernmental Panel on Climate Change (published in 2013) is expected to increase political pressure for a higher ambition level. There is also an ongoing active discussion in the EU regarding the EU 2030 climate and energy policy framework. Kemira is carefully following the public discussion on energy and climate policy development for anticipating the potential implications on our operations.
In 2013 Kemira defined the Kemira Carbon Index to monitor our CO2 performance from both consolidated and individual manufacturing site perspective. The Kemira Carbon Index covers CO2 emissions of Scope 1 and Scope 2 excluding direct emissions from chemical processing, and is not dependent on production structure, production mix or volumes.
Based on our work to define the Kemira Energy Efficiency and Carbon Indices, the results from the E3 energy efficiency enhancement program, and considerations about stronger political pressure on reducing CO2 emissions, Kemira has decided to set a long-term target for CO2 emission intensity from our manufacturing operations. The target is to reduce the value of the Kemira Carbon Index to or below 80 by the end of 2020, in comparison to the Carbon Index value of 100 in baseline year 2012.
