Environmental targets

Reduced energy consumption by at least 10% in terms of absolute consumption (GWh) by 2016 compared to mean energy consumption in 2005. In 2010, Wärtsilä conducted energy audits in Spain, Italy and China. In Finland, energy audits have been conducted earlier. The energy audits identify the savings potential and measures to improve energy efficiency. The Wärtsilä energy audit programme continues in 2011. Energy savings actions are monitored on an annual basis. By 2010 energy savings of 6.5 GWh have been reached, which represents about 14% of the final target. 
R&D: The full release of 710 ppm NOx engine concepts for power plant engines and, in the case of marine engines, compliance with upcoming US and EU regulations. The emission levels for power plant engines have been reached: 710 ppm for W20 and W32 and 900 ppm for W46. The engine types have been released in various release stages. The full releases of various engine types are dependent on sufficient installation feedback. The Wärtsilä 26 marine engine was EPA certified in 2007. The targets were not fully reached.
R&D: Reducing the fuel consumption of diesel and gas engines, reducing fuel consumption and emission levels in 2-stroke engines, and reducing emission levels in common-rail engines. Wärtsilä has developed technologies to improve the efficiency of diesel and gas engines by 3% compared to 2005 levels. The target was reached. IMO Tier II compliant solutions have been rolled out to the entire 2-stroke engine portfolio. The RT-flex engine models have a higher optimisation potential than their RTA counterparts, resulting in IMO Tier II compliance with a clearly lower (~0) fuel consumption penalty and lower fuel related emissions. Thereby, further increasing the total efficiency of the complete system above the earlier reached 12% by applying waste heat recovery could so far not be achieved.
Ship Power: Broadening of the gas concept, increasing sales of environmental seals, and improving the propulsive performance of seagoing vessels. The target concerning broadening the gas concept and environmental seals has been reached already earlier. In certain ship types it has been demonstrated that efficiency targets have been clearly exceeded. Projects for further improving total vessel efficiency are ongoing.
Services: Increase in diesel-to-gas engine conversions, sales of exhaust gas scrubbers, and an increase in the number of engines covered by CBM and O&M agreements. CBM target (5,000 MW) has been reached. The gas conversion target (2,000 MW) was not fully reached. By 2010, gas conversions totalled approx. 600 MW. The exhaust gas scrubber target was not reached. The first commercial scrubber retrofit was sold in 2010. The O&M target (4,500 MW) has been reached.  
Power Plants: Introduction of a combined effluent treatment unit for treating various plant effluents, the market launch of wet techniques for optimised NOx reduction and fuel economy, and the active sales and marketing of power plant technology based on renewable fuels. Power Plants has delivered and validated the combined effluent water treatment concept and has readiness to deliver it when local effluent standards require it. This target was reached already earlier.  Wet techniques for NOx reduction has been extensively studied in engine laboratory conditions. This application has, mainly due to its large consumption of pure water, not raised any bigger interest from the market and further development is on hold. The target was not reached. Power Plants has gathered a broad experience of operating engines on different types of renewable fuels with both vegetable and non-vegetable origin. By 2010, Wärtsilä had sold in total approx. 800 MW of liquid biofuel power plants. This target was reached already earlier.

 The targets above were set in 2005. Wärtsilä will set new environmental targets during 2011.
