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.

(For examples of initiatives at each business site, please refer to Environmental Report 2015 “Initiatives that Deal with Biodiversity”)

Initiatives of Each Business Facility

■ Komatsu Osaka Plant: “Osaka Biodiversity Partner Agreement”

On March 15, 2016, the Osaka Plant—one of Komatsu’s major domestic plants—entered into the “Osaka Biodiversity Partner Agreement” with Osaka Prefecture, Osaka Prefecture University, Osaka Prefecture Research Institute of Environment, Agriculture and Fisheries, and Hirakata City.

The “Osaka Biodiversity Partner Agreement” is a policy created by Osaka Prefecture in collaboration with the university, experimental research institute and the local municipalities to support businesses that are taking the initiative to work on protecting biodiversity. The purpose of the policy is to promote biodiversity protection activities by businesses, and was started in 2013, ahead of Japan’s other prefectures.

Based on this agreement, each partner takes a role in promoting the building of an ecological network through the management of the green space within the Osaka Plant premises (Komatsu Satoyama) that takes biodiversity into consideration. Furthermore, by using it (Komatsu Satoyama) as a field for nature observation groups for citizens, a ripple effect of contributing to the community and increased awareness of biodiversity can be expected.

The “Komatsu Satoyama” of Osaka Plant is 1,500 m2 and is made up of a biotope pond and a community forest where Pin Oak and Sawtooth Oak trees that were planted when plant construction was completed grow tall above the forest floor. There are also rare species of aquatic plants growing in the pond and the number of spot-billed ducks is increasing every year.

Initiatives for Biodiversity in Logistics
(Reduction in wood and cardboard packing materials (domestic))

The logistics department of Komatsu has been separating packing materials into metal, plastic, wood and cardboard to carry out activities to reduce the amounts used.

When biodiversity was added to the Komatsu Earth Environment Charter in 2010, the logistics department started improvement activities, with the reduction of wood and cardboard packing materials being the main focus, based on the perspective of forestry conservation.

FY2015 Improvement Target: Basic unit of packing material used per cargo weight (kg/ton) Compared to FY2010 △10%

By making improvements such as using returnable palettes, changing materials, and simplifying/eliminating packing materials—with a particular emphasis on improving the packaging of supplementary parts and Osaka Plant’s CKD parts for which large amounts of packing materials had been used—the FY2015 target was reached in the second year from when the activities were initiated from FY2011. And, by continuing with improvements since then, the following results were achieved.

<FY2010 - FY2015 Activities Results>
  • Basic Unit of Packing Material Used per Cargo Weight (kg/ton)
    Compared to FY2010 △24.8 %
  • Amount of Wood/Cardboard Used
    FY2010 - FY2015 Cumulative Total △1,978tons
    The amount of wooden packing materials reduced when converted to cedar trees (tree age 50) is equivalent to 4,457 trees(*1).
    From the forestry conservation perspective, we kept 4,457 trees from being cut down. Also, the amount of CO2 absorption converted to cedar trees is 62(t-CO2/year)(*2).
    *1. One 50 year-old cedar tree weighs approximately 0.444 tons.
    *2. Amount of carbon absorption by one 50 year-old cedar tree is approximately 14kg/year.

  • Improvement Status of Returnables
    -Returnable use rate for spare parts’ packing cases: 46% improvement (compared to FY2010)
    -Returnable use rate for CKD packing (all-purpose) cases: 22% improvement (compared to FY2010)
<Improvement Example of Wooden Packing Materials Elimination>
