Komatsu's Environmental and Social Activities Enhancing Quality of Life

Mitigating Climate Change  Reducing CO2 Emissions in Manufacturing Operations

As part of our efforts to mitigate climate change, Komatsu has adopted an indicator of CO2 emissions per unit of manufacturing value with respect to the amount of electricity, fuel gas, fuel oil, and other types of energy used in manufacturing operations. The Company established aggressive mid to long term objectives in FY2007, setting a target of 20% reduction in average CO2 emissions in FY2008 to FY2012, as compared to FY2000 levels.

In May 2012, medium-term goals had been for the 7th consecutive year, achieving a reduction in the averages between 2008 to 2012 at approximately 29% compared to FY2000 levels. The primary impetus came from enhanced production efficiency, which resulted from the inauguration of a new high-efficiency line and the removal of an obsolete line and from the horizontal deployment of various improvements from the "Company-Wide Energy Saving Project Group" deployed in May 2012, as well as from other measures.
