OMRON Group’s Biodiversity Policy

Basic policy

As part of the company’ s commitment to corporate social responsibility, OMRON joins worldwide efforts to halt the accelerated loss of global biodiversity that occurred after the mid-20th century. Toward this end, OMRON seeks to preserve biodiversity from the dual perspectives of business operations and community contributions. To ensure the validity and effectiveness of its efforts, OMRON will focus its attention on the following three points: 1) Collaboration with concerned stakeholders; 2) Emphasis on objective assessment of effects and continued improvements; and 3) Reduction of risks and maximization of benefits shared across society.

Course of Action

  1. - Business operation perspective
    1. ①Innovation driven by social needs
    2. ②Promotion of environmental protection and activities based on the environmental management system
    3. ③Implementation of biodiversity preservation efforts across the value chain
  2. - Social contribution perspective
    1. ①Activities intended to earn greater trust from society
    2. ②Activities intended to motivate employees to take part in biodiversity preservation efforts

OMRON will work to help protect biodiversity by emphasizing the course of action mentioned above.

OMRON Group’ s Biodiversity Policy Formulation Process

OMRON formulated a biodiversity policy in collaboration with Conservation International* (CI), an international NGO. During the course of policy formulation, OMRON was advised by CI to maintain perspectives of validity, efficacy, and efficiency (degree of contribution) when planning a policy or activities. These points are also essential to consider in addition to the more fundamental discussion of why the OMRON Group needs to address biodiversity issues.

After this process, OMRON reached a conclusion: "A company exists in a human society, which in turn exists in a natural society." Based on its belief that a business should create value for society through its key practices, OMRON considers conserving biodiversity as an important plank in its commitment to sustainability (not just as a part of environmental preservation) as it works to realize a better society.

  • * Conservation International (CI) Conservation International (CI) is an international NGO founded for the purpose of solving environmental issues by emphasizing relationships between ecosystems and people. CI’ s mission is to empower societies to responsibly and sustainably care for nature and global biodiversity by building on the foundation of science, partnership, and field demonstration. By so doing, CI aims to pass on the rich natural environment to generations to come and contribute to the well-being of humanity.

Biodiversity Initiatives

Preservation of biodiversity reflecting regional characteristics and issues

OMRON’s approach to preserving biodiversity is to make use of its Group sites including offices and factories and promote activities that reflect the characteristics and issues of each region.

Protection and breeding of the striped bitterling, an endangered species, in a biotope

OMRON's Yasu Office uses approximately 1,000m3 of groundwater per day to manufacture semiconductors. This is equivalent to the amount of water used by about 1,200 general households a day. Also, the Yasu Office is located in Shiga prefecture which contains Lake Biwa, known as the "Mother Lake." For this reason, the Yasu Office is particularly committed to preserving the environment, making sure to only release factory wastewater after it has undergone a sufficient level of purification.

Against this backdrop, the Yasu Office in 2011 created a biotope*1 named the "pond of bitterlings," using the factory wastewater within its premises. To make effective use of wastewater discharged from the factory without endangering living creatures in the region, the Yasu Office employees are working to protect and breed the striped bitterling*2 with advice from experts at the Lake Biwa Museum. The striped bitterling is a class IA endangered species designated by the Ministry of the Environment.

In fiscal 2017, the Yasu Office took a new initiative to grow shellfish healthily and renovated the pond. In early May, 2018, the Office saw the birth of bitterlings for the first time in two years, confirming about 80 juvenile bitterlings by July.

Since 2013, the Yasu Office holds nature observation tours every summer for neighboring residents and other guests. In 2017, the Office invited about 160 children from neighboring after-school day-care centers, as well as about 180 of five/six graders as a part of classwork, giving them an opportunity to learn about the importance of nature and environment at the biotope. Also, the Nikkan Kogyo Shimbun (the Daily Indutry News) hosted a fieldwork in Shiga, visiting the site to learn about the Office's initiatives in environment conservation. They are among many who visited the biotope.

OMRON will continue working to preserve the environment by conducting breeding experiments and hosting the nature observation tour.

  • *1 Biotope
    "Biotope" is an English word derived from the German "biotop," which in turn was derived from the Greek "bios" (life) and "topos" (place). The word means a living place for a specific assemblage of plants and animals. Recently, the term "biotope" is also used as a generic term to collectively describe forests, rivers, marshes, swamps, grassland, woods, etc. as ecosystems. In Japan, the term is often used to describe an artificially created simulation of a natural habitat for a particular species.

  • *2 The striped bitterling (Acheilognathus cyanostigma)
    A species of freshwater cyprinid fish that once inhibited the Lake Biwa and Yodo River water systems in large populations. Due to the growth of non-native species and river development projects, this fish is no longer seen in Lake Biwa. It is designated as one of the most endangered class IA species in the Ministry of the Environment’ s Red List. Its name was derived from a long blue green stripe on the sides of its body.

OMRON Iida supports protection of Iida City’ s protected species of butterfly

The Iida Office of OMRON Automotive Electronics Co., Ltd., an OMRON Group company in Iida City, Nagano Prefecture, cooperates with the city in the protection of the Japanese Luehdorfia butterfly*, designated as one of the city’ s protected species.

OMRON Automotive Electronics’ Iida Office is located within the Kiribayashi Eco-Industrial Park, which was chosen as a "home to creatures" by the Environment Agency in 1989. Therefore, when the company constructed a new factory building, OMRON Automotive Electronics chose a wall color that does not hinder the inhabitation of the Luehdorfia butterfly, which is susceptible to sunlight. The company also gave up constructing a connecting road between its factory buildings and decided to use the city road. These measures demonstrate that the company will spare no effort to preserve biodiversity. Iida Office staff also engages in cleaning and beautification of the park three times a year.

In addition, the Iida Office lends a parking area to the Iida Insects Association. This association has been dedicated to the study and research of the Japanese Luehdorfia for over 20 years, and the parking area is made available to association members when they come to observe the butterfly. The Iida Office also supports the protection of Heterotropa takaoi, a feed herb for this butterfly.

  • * Japanese Luehdorfia butterfly
    A small butterfly in the Papilionidae family nicknamed "Goddess of the Spring," because it incubates in the spring. The number of Luehdorfia at one time declined to a level approaching extinction due to excessive collecting.
