Komatsu's Environmental and Social Activities Enhancing Quality of Life


Mitigating Climate Change (Initiatives to Mitigate Climate Change in Business Operations) 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 more aggressive mid to long term objectives in FY2013.

In 2010, to contribute to Post Kyoto Protocol climate change measures, a mid-term goal for 40% reduction compared to 1990 levels by 2015 was established but following the start of activities to halve power consumption, activities are under way to achieve an ambitious 54% reduction compared to FY2000 levels.

Energy-saving activities were undertaken through the establishment and start of high efficiency lines and removal of old lines along with adopting renewable energy and horizontal expansion of various production improvements revolving around the "Company-Wide Power Reduction Project Team" established in May 2012. However, due to the increased fuel consumption by engine research and testing, the index for the CO2 emissions per unit of manufacturing value worsened compared to the previous fiscal year. Development of a new generation engine will continue this fiscal year but the CO2 emissions index will be reduced through measures such as renewing old buildings of over 40 years with a building that adopts the latest energy-saving technology.
