Corporate Relationship with Ecosystems

Corporations depend on "ecosystem services," including the natural supply of materials like fibers and wood, and the ability of ecosystems to maintain the quality and quantity of air, water, and soil. Contributing to ecosystem preservation through both business and social activities enables companies to continue receiving these benefits and to restore ecosystems.

Through its business activities, Hitachi is promoting designs and production methods that reduce the impact on ecosystems throughout the product life cycle. We are also increasing the number of products and services that directly help preserve ecosystems, such as water purification measures. We view chemical substance management as part of ecosystem preservation and continually ensure that it is carried out correctly. To contribute to society, we encourage employee volunteer programs, such as tree planting and ecological surveys of rare plants and animals, as well as other programs that preserve ecosystems.

Corporations and Ecosystems


Initiatives to Preserve Ecosystems

In fiscal 2016 Hitachi created an Ecosystem Preservation Activities Menu citing the specific activities to be undertaken to promote the preservation of the ecosystem. We are encouraging each business site to advance their own initiatives. This menu was created by adding the pioneering activities of other corporations and organizations to the list of items that had already been subject to assessment since fiscal 2010. It consists of 116 items covering all aspects of our business operations, including the value chain. Each business site selects those activities it plans to launch from the menu, and the total number of initiatives becomes Hitachi's target for ecosystem preservation. In fiscal 2016, 144 new initiatives were launched, far in excess of our initial goal of 30.

In the long term, we seek to minimize the impact on natural capital and realize a harmonized society with nature by minimizing the burden (negative impact) on the ecosystem caused by business activities and maximizing the positive impact, such as by undertaking social contribution activities to protect nature and providing products and services that preserve the ecosystem.

Regarding impact and other ecosystem preservation assessments, we are deliberating the matter not only within the Group but also through our participation in activities outside the company, such as the biodiversity working group of four Japanese electrical and electronic industry associations*1 and the Japan Business Initiative for Biodiversity (JBIB).

The Japan Electrical Manufacturers' Association (JEMA), Japan Electronics and Information Technology Industries Association (JEITA), Communications and Information Network Association of Japan (CIAJ), and Japan Business Machine and Information System Industries Association (JBMIA).

Next Steps

For fiscal 2017, we have set a target of implementing 150 new initiatives in accordance with the Ecosystem Preservation Activities Menu and will continue to further promote ecosystem preservation activities throughout the Group.

Ecosystem Preservation Activities

Hitachi Group Forestation Activities

Working together with employees and their families, the Hitachi Group participates in the Japanese Forestry Agency's Corporate Forest Program to preserve forests in several locations.

Yuyu Forest (Hitachi Power Solutions Co., Ltd.)

Hitachi Power Solutions has been conducting tree-planting activities since 2007 in the Yuyu Forest in the city of Takahagi in northern Ibaraki Prefecture. Each year employees and their families gather to plant trees, clear underbrush, prune, and perform other forest maintenance activities under the guidance of the Ibaraki District Forest Office and Takahagi's forestry cooperative. These events also include environmental education, handicraft classes using pruned materials, and other activities that employees' families can enjoy together as they create healthy forests.

  • Tree-planting area: 10 ha
  • Number of trees planted: 31,510
  • Total number of participants: 2,016

Yasato Forest (Hitachi High-Technologies Corporation)

Hitachi High-Technologies embarked on a 60-year plan in 2005 to cultivate trees in the Hitachi High-Tech Yasato Forest in the city of Ishioka in southern Ibaraki Prefecture. Employees and their families participate in the work of pruning and thinning to grow a healthy forest.

  • Tree-planting area: 2.32 ha
  • Number of trees planted: 5,600
  • Total number of participants: 1,387

Mangrove Seed Collection and Tree-Planting (Hitachi Terminals Mechatronics Philippines Corporation)

Collecting seeds from mangrove plants.

In June 2016 Hitachi Terminals Mechatronics Philippines (HTMP) planted 883 seedlings grown from mangrove seeds collected in advance to protect and grow the mangroves remaining in the Subic Bay special economic zone where its factory is located.

Mangrove forests are a valuable part of the natural ecosystem in the Philippines, but at the same time the mangrove ecosystem is fragile and requires protection. HTMP has conducted tree-planting activities for some time, but in fiscal 2016 it expanded its activities to collecting seeds from mangrove plants and raising seedlings. HTMP will continue to be actively involved in ecosystem preservation.
