To provide customers with products that are in harmony with the environment, it is necessary that raw materials, components, and parts purchased externally also be environment-friendly.
For that reason, Komatsu has formulated Green Procurement Guidelines and gives preference to purchases of products that have limited environmental impact. In addition, Komatsu has distributed Environmental Check Sheets to its major business associates in an effort to gain an understanding of its associates' environmental management systems and environmental impacts. Komatsu also requests that these associates acquire certification under an environmental management system.
In January 2007, Komatsuís Ibaraki Plant, which manufactures wheeled large construction and mining equipment, was founded immediately adjacent to the port of Hitachinaka in Ibaraki Prefecture, Japan. The new plant manufactures primarily dump trucks and wheel loaders for the market outside Japan, with over 90% exported around the world to North America, Europe, Asia and the Pacific, Africa, and Latin America. For reducing its CO2 emissions, this plant has greatly shortened shipping distances by ship loading and exporting products at the immediate neighbor, the port of Hitachinaka.
Furthermore, even for the large construction equipment produced at the Ibaraki Plant loaded onto ships and exported from Tokyo or Yokohama, Komatsu has launched exclusive-use inland shipping for large construction equipment between the Ibaraki Plant and the ports of Tokyo or Yokohama, resulting in CO2 emissions reductions through the modal shift from land-based transport in trailers. These innovations are expected to yield reductions in CO2 emissions by some 2,300 tons annually.
Moreover, the new plant is a model environment-friendly plant boastingeco-friendly features such as solar panels for energy conservation.
In January 2007, construction finished on the Kanazawa Plant, which was built on a site adjacent to the port of Kanazawa in Ishikawa Prefecture, Japan. The new plant, which manufactures large presses used to form automobile body parts, utilizes an integrated manufacturing method for sheet-metal working, cutting, and assembling pressesí main components. Through processing improvements using this integrated manufacturing method and reductions in shipping distance using the adjacent port of Kanazawa, this plant has reduced CO2 emissions by over 200 tons a year, lessening the plantís environmental impact.
Improvements in the Transport of Products
The Osaka Plant, which manufactures large construction equipment, has been using a domestic ferry for shipping over long distances. In FY2006, the plant undertook a modal shift by switching from trailers to domestic ferries for shipping large construction equipment over medium distances.
Moreover, the Oyama Plant, which manufactures components for engines and hydraulic equipment, has been using rail-based transport for shipping components to automobile body plants a long distance away. In FY2006 the plant expanded this system to products sold to outside businesses, furthering its CO2 emissions reductions. The Awazu Plant, manufacturing transmission components, has also been advancing the shift from truck-based to rail-based methods for shipping components to factories a long distance away.
These ongoing improvements have resulted in a reduction of 1,200 tons of CO2 emissions each year.
