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 Logistics

Lower the CO2 of Global Transport

(Basic Unit of CO2 Emissions per Cargo Weight)

In 2011, Komatsu began improving its assessment of CO2 emissions from logistics operations for its 10 major international business locations.

Improvements were made on a consolidated basis globally at all 25 business locations, including domestic locations.

Average transport distance increased for domestic and overseas in FY2013. As a measure to address the reduction of increasing CO2, expanding the modal shift will be central to furthering improvements.

As a result, improvements of -6.3% domestically and -1.8% abroad were achieved but there was a variation in the average distance of transportation due to a change in destination and the basic unit of CO2 emissions per cargo weight increased 4.6% domestically and 3.0% abroad.

Improving the Rate of Modal Shift

In FY2013, CO2 reduction activities were implemented with a focus on improving the modal shift of four global plants where long-distance transport by truck trailers were increasing due to changes in the transport destination.
Japan: Product transport from Awazu, Osaka, and Tochigi plants
International: Product transport from CMO (Chattanooga, America) Plant

Japan: Focus on Switching Tohoku Bound Long-Distance Truck Transport that Increased Since the Great East Japan Earthquake to Coastal Shipping

Efforts were made to reduce increasing CO2 volume through the promotion of low energy basic unit transport.

Improvements focused on increasing the use of coastal shipping for construction machinery products shipped from Awazu/Osaka plants to Tohoku region and using coastal shipping for forklifts shipped to Kyushu region from Tochigi plant.

In FY2013, the effect of CO2 emission reductions at domestic plants targeted for modal shift improvements was -1,086 (tCO2/year) and contributed to 4.5% reduction in the total CO2 emissions from Komatsu transport.

Oversea: Switching Long-Distance Transport of Products to Rail Transport on the American Continent

CO2 was reduced through the promotion of low energy basic unit transport. The main improvement was to switch the transport of CMO (Chattanooga, America) plant products from truck transport to rail transport.

Previously components were transported by containers (rail) but products (finished vehicles) were transported by long-distance trucks. From FY2012 the transport of products (finished vehicles) were also transitioned to rail transport.

The distance from CMO to the intermediate stockyard Rochester for supplying West Coast of the United State's and Canada's West Coast area customers customers is a very long 4,145km and the CO2 reduction effect of switching to rail is also great.

■Reduction in CO2 Emissions (t-CO2/year)
FY2012 ▲1,260
FY2013 ▲455
Total ▲1,716

The effect in FY2013 contributed to a 2.6% reduction in total CO2 emission volume from North American region transport and a 1.3% reduction in CO2 emissions by transporting from all targeted plants abroad.
