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.

Evaluation of Activities concerning Biodiversity

■Utilization of the "Land Use Score Card"

Komatsu utilizes the "Land Use Score Card" and the "Living Things Monitoring Sheet" formulated by Japan Business initiative for Biodiversity (JBIB), a general incorporated association.

The "Land Use Score Card" scores the effort level of a business site in its biodiversity activities out of a maximum of 100 points in 3 categories consisting of 17 items.

Komatsu conducted this evaluation at 15 of our bases in Japan, including the head office. Of those, the 2 top scoring bases are presented below.

We will continue to promote activities in order to strive to achieve higher scores in this evaluation.

■Study Conducted with the Living Things Monitoring Sheet

The Living Things Monitoring Sheet allows employees to monitor organisms even if they are not experts through the identification of silhouette, and is a collection of species that act as an indicator of the environment. As shown below, the silhouettes are divided into 66 species in all.

The results of the studies conducted at the 15 Komatsu sites throughout Japan are shown below. Depending on the site, studies were conducted 4 times throughout each season at business facilities.

Moving forward, these studies will be periodically conducted each year.

Class Number of Species
Fowl 17
Odonata 5
Branchiura 8
Hymenoptera 4
Cicadidae 1
Coeoptera 7
Achidioidea 1
Aquatic Insects 4
Arachnids 2
Pulmonata 2
Bombina 3
Plants 4
Fungi 3
Edaphone 5

Initiatives of Each Business Facility

■Oyama Plant: Biotope Construction

At the Oyama Plant, 10,000 tons of flood-control space and green pond were preserved on the plant's premises. In the future, we plan to construct a biotope and natural wood area in this area.

In some areas, work such as pruning and thinning the brush has already started. Colonies of herons and several rare plant species have been observed in this area. We plan to maintain the area, to further promote conservation activities.

■Komatsu Castex: Study on Ponds

Komatsu Castex is surrounded by ponds that have never been observed by anyone, and so these ponds were studied for the inhabitant organisms.

Among other species, the common carp, crucian carp, Chinese pond turtle, mitten crab, and killifish were identified. In particular, the number of crucian carp was a great surprise; there were 432 of them living in the pond.
