Komatsu's Environmental and Social Activities Enhancing Quality of Life


Mitigating Climate Change  Reducing CO2 Emissions in Logistics

Lower CO2 Emissions 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.

In FY2012, a mid-term improvement plan was drafted to improve CO2 emissions at factories abroad, setting an 8% reduction (as compared to 2011 levels) as the goal for 2015. Komatsu is working towards achieving this goal.

Improvements made domestically in Japan will be applied abroad to achieve this goal.

Reducing Transport Distance by Utilizing Near Ports

KUK and Unloading Distances

KUK and Land Transport Distance

■Abroad: England's KUK Plant

Parts imported from Japan for component assembly (CKD) were unloaded at Southampton Port then transported by rail to the KUK Plant. By changing the unloading port to South Shields the land transport distance was reduced by 94%.

The effect on CO2 reduction was 177 t- CO2/year.



Hitachinaka Port Usage Rate

Hitachinaka Port Usage Rate

■Domestic: Ibaraki Plant

The usage rate of Hitachinaka Port, closest to the Ibaraki Plant, surpassed the mid-term goal of 95% for an 11.6% increase to the previous year at 96.1%. The change in usage from unloading at Yokohama for transport by truck (160km) to unloading at Hitachinaka Port and transporting 4km resulted in CO2 reduction by 65 t- CO2/year and the land transport distance was reduced by 98%.
