Environmental Protection

Biodiversity

The Mitsui Chemicals Group works to reduce its impact on biodiversity through our business activities and throughout the life cycle of its products.

The manufacture of chemical products has the potential to impact biodiversity in the air, water, and soil through GHG emissions associated with energy consumption (electricity and thermal energy, among others), the use of water resources, and impacts on water quality through effluent. In addition, chemical substances with hazardous properties and their degradation products may affect ecosystems and species if they are released into the environment during any stage of a product's life cycle, including manufacturing, use, and disposal. In addition, if hazardous chemical substances and their decomposition products are released into the environment during the manufacture, use, and disposal stages of products, they may have impacts on ecosystems and species.

To prevent any loss of biodiversity and achieve harmony with the natural environment, the Mitsui Chemicals Group is promoting a variety of initiatives, including mitigating climate change, advancing the recycling of resources, managing chemical substances and reducing environmentally harmful substances.

Basic Approach to Biodiversity Conservation

We conduct our business activities in gratitude for the blessings of nature and biodiversity and recognize that environmental preservation is a globally important issue.
We contribute broadly to society by encouraging biodiversity conservation through the supply of environmentally friendly materials, products, and services.
We will comply with international biodiversity agreements.
We strive to conserve biodiversity by cooperating with relevant parties in Japan and abroad and within and outside the company and taking into account its effect in the supply chain.
To conserve biodiversity, we will promote employee social contribution activities that have our stakeholders trust.

Biodiversity Risk Assessment

Believing that reducing environmental burdens throughout the Mitsui Chemicals Group’s production and business activities helps preserve biodiversity, we undertake initiatives that include managing chemical substances, reducing GHG emissions, and managing water resources.

As a chemical company whose operations are particularly dependent on natural capital such as raw materials, water resources, and land, we believe it is necessary to assess our impacts on natural capital and biodiversity, take steps to mitigate negative effects, and contribute to a nature-positive society.

To date, we have conducted surveys related to natural conservation areas—including World Natural Heritage sites, IUCN categories I, II, III, and Ramsar Convention wetlands—at our Group production sites in FY2017, and biodiversity risk assessments using the WWF Biodiversity Risk Filter (BRF) in FY2023. Beginning in fiscal 2024, we have expanded the scope of our assessment to include the value chain and stakeholders, and have initiated consideration based on the LEAP approach* recommended by the Task Force on Nature-related Financial Disclosures (TNFD).

In the Locate phase (L1 and L2), we assess ecosystem-related risks and dependencies in both upstream and downstream segments of the value chain, as well as in our direct operations, for each business portfolio. This assessment is conducted using tools such as ENCORE. In the chemical sector, we have identified that elements such as water resources (including water usage and water quality) and pollution (including pollutant emissions) are of high importance. In FY2025, for major production sites under our direct operations, we conducted tool-based assessments of biomes, biodiversity importance, ecosystem integrity, the importance of ecosystem service provision, and water risk, and shortlisted potential high-risk sites. Going forward, we will continue to conduct impact assessments using site-specific data to identify sensitive locations of particular relevance to our company.

* LEAP Approach:

An integrated approach for companies to evaluate nature-related issues in preparation for TNFD disclosure, consisting of four steps: Locate, Evaluate, Assess, and Prepare.

Contributions through Products and Services

The Mitsui Chemicals Group is developing products and services that help reduce environmental burdens. Formulating Blue Value™ as a means for displaying environmental contribution value, products that help "Reducing CO₂", "Conserving resources", and "Coexisting with nature" are designated as Blue Value™ products.
Setting Blue Value™ products sales revenue ratio as a KPI in VISION 2030, we aim to expand product groups that help conserve biodiversity.
In addition, the Group, which has been vigorously promoting a shift to business with a social challenge perspective, also focuses its attention on biodiversity related social challenges and aims to provide products and services that contribute to solving such challenges.

TOPICS: Product development aimed at marine life conservation

Mitsui Chemicals has developed NAGORI™^*, a product that contains up to 75% of mineral components found in seawater.
This product was born from an employee’s idea. Focusing on the fact that the desalination technology—a solution for the social challenge of water shortages—is a trade-off with another new challenge, coral extinction caused by concentrated brine produced as a by-product in seawater desalination, the employee came up with an idea of developing products using rich minerals in the concentrated brine as the main raw material.
NAGORI™ received high praise from members of the judging committee for its innovative chemical technology utilized to tackle the environmental challenge, earning selection into the Good Design Best 100 as one of the top 100 winners of the 2018 award.

*NAGORI™:
An innovative material created from seawater minerals. Mitsui Chemicals has used its state-of-the-art compounding technology to grant material thermal conductivity similar to that of ceramics along with a weighty feel and ease of mass production.
In the future, Mitsui Chemicals intends to take the concentrated brine produced as a by-product in seawater desalination and use the raw materials from this for NAGORI™. As a chemical company, we are looking at how to create tangible solutions in pursuit of environmental friendliness, Sustainable Development Goals (SDGs) and how as a society we should approach true sustainability.

Contributions through the Supply Chain

In procuring our raw materials, we are making efforts to select materials and suppliers that will result in a lower environmental impact in line with our Purchasing Policy. As we include“preservation of biodiversity” to the Sustainable Procurement Guidelines, we request our suppliers to support the preservation of biodiversity. In logistics, we work to reduce environmental impact mainly by undertaking modal shifts and shared logistics. We provide product safety information in an effort to help customers handle products appropriately and minimize environmental impacts.

Participation in Initiatives

We support the aims of the Taskforce on Nature-related Financial Disclosures (TNFD), an international initiative launched in June 2021, and participate in the TNFD Forum.
We also support the Declaration of Biodiversity by the Japan Business Federation (Keidanren) and participate in the Japan Business and Biodiversity Partnership. The policy and initiatives of Mitsui Chemicals in this area has been introduced in Initiative on the Declaration of Biodiversity by Keidanren.

Preservation Activities at Omuta Works

At the Omuta Works (Fukuoka Prefecture), Mitsui Chemicals has a protected forest that spans approximately 5.4 hectares and engages in ongoing activities to preserve this area. In 2009, we cooperated on a survey of the natural environment in the forest around our property (the southern side of Mt. Takatori) at the request of Omuta City, which considers the preservation of the natural environment an important issue. The survey conducted by Omuta City Natural Environment Survey Association examined rare plants and species of living organisms in areas managed by Omuta Works, and presented its findings in the Omuta City Natural Environment Survey Results Report.

Rare Wildlife Found in Survey (example)

Plants	Serissa japonica, tree of a thousand stars
Plants	Selaginella moellendorffii
Amphibians	Japanese brown frog
Insects	Cydnidae, Parastrachia japonensis

Donations to Environmental Conservation Organizations

Mitsui Chemicals employees have been annually donating to the Japan Environmental Action Network (JEAN) — an NGO that engages in ocean and river environmental preservation activities—through the One-Coin Club since fiscal 2015.
