Water Resources


Basic Concept

We consider that biodiversity creates diverse values and services such as water, plants, and oxygen on the earth, and it is one of the most important existences that support the IDEC Group's business continuity. We also think that biodiversity is an important issue to be addressed as well as climate change.

In October 2022, IDEC approved and signed the statement of BUSINESS FOR NATURE at COP15 for mandatory assessment and disclosure of biodiversity framework, and we will proceed to prepare for the information disclosure of the impact of our business on the environment and relating-environment for accomplishing 2050 vision of "societies in harmony with nature" stated by Convention on Biological Diversity.

Moreover, based on the framework of "Governance", "Strategy", "Risk Management", and "Metrics and Targets" of four indexes for Taskforce on Nature-related Financial Disclosures (TNDF), our Environmental Strategy Committee which chairperson is the Senior Executive Officer in charge of the environment, has considered the future directions and code of conduct for biodiversity.

Analysis of Biodiversity Risks

Since FY2024, we have conducted the analysis and assessment of IDEC group's biodiversity risks in order to define indexes that helps to study impacts on biodiversity by IDEC group's business activities and monitor biodiversity results. As an assessment tool, we adopt Biodiversity Risk Filter developed by World Wide Fund for Nature (WWF) to quantify biodiversity risks by country. In addition, we identified top 10 biodiversity risk indicators of of the whole group. 

The following graph shows the quantified results of the IDEC group's biodiversity risks based on the risk assessments of each site by country. Overall assessment of nineteen sites in the world were rated as low or medium risks, and there was no site with high biodiversity risk.

The following graph shows the quantified results of the IDEC group's top 10 biodiversity risks based on the assessment of each site. The biodiversity risk index with the highest risk is Tropical Cyclone, and a total of 11 sites in three countries of Japan, China and Taiwan are rated as extremely high risks. All the nine sites in Japan are rated as extremely high risks, which indicates that typhoons greatly impact on biodiversity around IDEC's sites in Japan. The biodiversity risk index with the second highest risk is Pollution, and four sites in three countries of Denmark, China, and Tunisia are rated as extremely high risks. The biodiversity risk index with the third highest risk is Landslides, and three sited in Japan are rated as extremely high risks.

As a next step, we will investigate and analyze the actual status of the impact on sites rated as extremely high risks by tropical cyclones that are assessed as the highest risk.

Greening of IDEC Group's Business Sites

We have addressed to preserve biodiversity through greening of our business base sites.

IDEC's Head Office


In June 2018, the courtyard was renovated and more than 30 kinds of trees including local varieties of Japan were planted. Lowering the surrounding temperature is expected by greening.  In March 2023, the IDEC head office’s green space was certified as a private business green space with excellent conservation and creation activities under the Social and Environmental Green Evaluation System Operation, Management and Active use program (SEGES OMA) of the Organization for Landscape and Urban Green Infrastructure.

<Walls of the well-being center >

Green walls are installed on the 3rd floor of the well-being center (north, west and south sides) built in June 2019 at the head office. It has an energy-saving effect by suppressing the rise in the surface temperature of the building, and is also expected to reduce CO2 by photosynthesis of plants. Currently, the ivy is growing and about 150 square meters will be covered with it.

Environmental Education

We have distributed the series of must-know environmental words and E-Learning via intranet since FY2021. In FY2023, we added the topics about "biodiversity" which summarize the relationship between biodiversity and climate change as well as the impact of the environment on living organisms.

Environmental Activities with the Participation of Employees

"Biodiversity" Photo Contest (Global)

We hold the CSR month in every October globally. In FY2023, we held a photo contest with the theme of "biodiversity", and there were many applications from all over the world. Winners were determined with the voting by the members of the Environmental Strategy Committee, and they received each prize named after IDEC's eco-friendly product names and biodiversity.

Activities by Group Company and Business Base


During the CSR month of October 2022, voluntary employees and their families cleaned up around the Mt. Dayangshan in Suzhou National High Tech district. Participants wore the original T-shirt designed with CSR logo, and they collected trash of 45L X 20 bags in total.

Amagasaki Business Site (Japan)

In April 2022, employees started to set seeds of sunflower near the side entrance, and greening activity has started. As sunflowers were raised politely, they had many flowers in summer, which became a summery scenery and healed employees. During the CSR month of October 2022, harvested seeds of sunflowers were provided to employees for the purpose of spreading green network. Activities for healing employees and making better environment will be continued in the future.

IDEC Head Office (Japan)

In July 2022, the event of picking lavenders were held at the rooftop garden of the 3rd floor, head office building. In this rooftop garden, diverse herbs such as lavender, sage, and lemon grass are planted, and many bees and ladybugs gathering nectar are seen. We can also enjoy their flavors. Approximate 30 employees of head office joined the event on the day.

Biodiversity through "food"

In order to have employees feel familiarity with biodiversity through food, dishes with sustainable materials were provided at the cafeteria of head office during the CSR month in October.

Cafeteria of the IDEC Head Office (Japan)

Salmon cream pasta used with farmed salmon and salmon roe acquired the international certified standard “ASC certification” (left photo) and lemon creme pasta with shrimp (right photo) were provided weekly. At the cafeteria of head office, the Rainforest Alliance Certified coffee is provided all through the year.


A “vegetable day” on which we have one meal or all meals with only vegetables was conducted at the office and the restaurant for vegetarians. Meals with only vegetables not only promote health but contribute to protect environment by forest protection and reduction of GHG and wastes in the situation of losing biodiversity caused by cattle raising

Water Resources

Basic Concept

Water resources are essential not only for human and plants, but all living organisms on the earth to live. On the other hand, approximate 2 billion people on the earth are forced to be in the condition of difficulty in using water controlled safely. It is said that 1.8 million children die annually caused by unsanitary water (Source: United Nations Information Center). 

Although the IDEC Group does not have any manufacturing processes or services that are heavily dependent on water resources, and most of the water resources we use are limited to water supply, we regard that water problems such as water shortage and water pollution impact on not only IDEC Group's business, but also the livings of our employees and their families.

Based on the "SAVING spirit" we have cherished since the foundation, we will use water resources with gratitude and address to reduce loads caused by our business activities on nature.

Analysis of Water Stress

Water resource is important for business continuity of the IDEC Group as well as for all the livings in the global environment. On the other hand, due to the impact of climate change such as global warming, water risks including water shortage, concentrated heavy rains, and floods are increasing every year.

For the purpose of controlling water resources properly and utilizing assessment results of water risks to business continuity, we have assessed water risks of 19 sites including manufacturing, development of all IDEC group in addition to head quarter. As an assessment tool, we adopted Aqueduct Water Risk Atlas 3.0 developed by World Resources Institute to quantity risks of water stress, riverline flood, coastal flood, and drought of each site. In addition, we investigated the amount of water intake per site.

The following is the world map that shows Aqueduct overall water risk per each IDEC site. Among 19 sites, three sites (one site in USA and two sites in Tunisia) were assessed as extremely high water risk, and one site in China was assessed as high water risk.

The assessment results of water stress indicates that three sites (one site in USA and two sites in Tunisia) were rated as extremely high risks, and three sites (in England, China, and Thailand, respectively) were rated as high risks.

The amount of water intake by six sites assessed as extremely high and high risks accounts for 35.1% of the total of IDEC group's water intake.

As for other risks, there are physical risks, groundwater table declines, seasonal variability, drought, riverline floods, and coastal floods, etc. We schedule to conduct risk assessments using Aqueduct once a year, and results will be updated.

Rain Water Storage and its Effective Usage to Greening (Head office)

Two rain water storage tanks were installed underground when the head office was constructed in 2013. Maximum 148㎥ rain water can be stored underground, and standing water has been used effectively for watering on the courtyard and sprinkling when the temperature rises.
