Komatsu's Environmental and Social Activities Enhancing Quality of Life


Mitigating Climate Change (Initiatives to Mitigate Climate Change in Business Operation) Reducing CO2 Emissions in Logistics

Lower CO2 Emissions of Global Transport
(Basic Unit of CO2 Emissions per Cargo Weight)

In FY2011, Komatsu began improving its assessment of CO2 emissions from logistics operations for its 10 major international business locations.

Since FY2006, improvements have started in domestic locations, and now been implemented on a globally consolidated basis at all 25 business locations.

Focusing the following points, Komatsu has been achieving improvement of transportation base unit and reduction of transportation distance by truck in Japan. One is to expand the use of Tohoku-bound coastal shipping, one prioritized area of improvement since FY2011, and the other is to expand the use of railway transport, another prioritized area of improvement since FY2014.

Changes in the shipping destinations, coupled with improved modal shifts, have cut the average land trucking distance for domestic plants by 7.4%, with the basic unit of domestic CO2 emissions improving by 5.8% compared to the previous year.

In the overseas scene, the need for long-distance trucking in the U.S. has been cut as a result of cross-sourcing North America-bound products from the CMO (Chattanooga, America) plant (with 44% of the total volume of North America-bound products having been switched to imports from the Osaka Plant in Japan and the BKC plant in Thailand).

Again, changes in the shipping destinations, coupled with the improvement at the CMO, have cut the average land trucking distance for overseas plants by 6%, with the basic unit of overseas CO2 emissions improving by 3.0% compared to the previous year.

Improving the Rate of Modal Shift in Japan

The rate of modal shift improved up to 29.1% in FY2014.

By making proactive use of coastal shipping in place of long-distance trucking, which had increased since the outbreak of the Great East Japan Earthquake in 2011, the rate of coastal shipping has expanded.

The rate of railway transport advanced by 1.7% to reach 6.1% in FY2014 after a continual effort to expand it having been pursued since FY2013 as a prioritized area of improvement.

Plants at which such effort was directed have gained a CO2 emissions reduction of 298 (t-CO2/year).

Cut in Long-Distance Truck/Trailer Transport
Resulting from the CMO (USA) Global Cross-Sourcing
and Railway Transport

The need for long-distance land trucking in the American Continent has been reduced by reviewing the categorizations of global production and unloading imported vehicles at the ports near the areas in which they are consumed (with 44% of the total demand for the CMO North America-bound products having been switched to imports from the Osaka Plant in Japan and the BKC plant in Thailand).

A modal shift to railway transport will be promoted for the CMO products to be transported over long distances as in the past.
