Komatsu's Environmental and Social Activities Enhancing Quality of Life


Biodiversity  Initiatives that Deal with Biodiversity

Komatsu will maintain our commitment to protecting biodiversity in our business activities, recognizing the impact of those activities on the ecosystem.

With the establishment of Komatsu's "Declaration of Biodiversity" and "Biodiversity Guideline" in January 2011, Komatsu business units worldwide began activities designed to preserve biodiversity.
Komatsu promotes initiatives to preserve biodiversity on two levels.

First, the Company continues to promote ongoing efforts to reduce the environmental impact of Komatsu's business activities. Komatsu also considers biodiversity when deciding how land is to be used, such as when building factories.

Second, Komatsu is becoming directly involved in the preservation of biodiversity, and at the same time expanding our "one-site, one-theme activities" to raise employee's awareness of the need to preserve local ecosystems.

Initiatives of Each Business Facility

■Oyama Plant: Biotope Satoyama Construction (Komatsu Manabino Mori)

At the Oyama Plant, 10,000 tons of flood-control basins and green space (untouched by human hands) were preserved on the plant's premises. We have begun construction to create a biotope and natural wood in this area as "Komatsu Manabino Mori."

Colonies of herons, some ducks, kingfishers and other birds, as well as several rare plant species have been observed in this area. Aside from being the focal point of employees' biodiversity conservation activities, we are also planning to make it a part of the factory visit course, to raise interest in those coming to observe the factory.

■KOMATSU CASTEX: Natural Revival of Water Lilies (Euryale ferox)

Some euryale ferox water lilies, a plant that has been categorized as extinct in the wild (reference material:Red Data Book Toyama 2002), was transplanted from the Himi City Junicho Lagoon (the only place in the prefecture with wild euryale ferox) to the ponds at the Himi plant. By caring for the surrounding area and making sure the plants get enough dredging and sunlight, we were able to produce the natural revival of the euryale ferox water lilies.
