Basic Approach to Biodiversity Conservation

  1. We conduct our business activities in gratitude for the blessings of nature and biodiversity and recognize that environmental preservation is a globally important issue.
  2. We contribute broadly to society by encouraging biodiversity conservation through the supply of environmentally friendly materials, products, and services.
  3. We will comply with international biodiversity agreements.
  4. 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.
  5. To conserve biodiversity, we will promote employee social contribution activities that have our stakeholders trust.

The Mitsui Chemicals Group aims to minimize the negative impact on the global environment and ecosystems from the products it manufactures and sells throughout their lifecycles.
The manufacture of chemical products has the potential for impacting biodiversity in the air, water, and soil through GHG emissions when using energy (electricity and thermal), the consumption of water resources in heating, cooling, and cleaning processes, and water-polluting effluent. In addition, the release and decomposition of harmful chemical substances at the manufacture, use, and disposal stages of chemical product lifecycles can reduce the number of species living in those environments.
The Mitsui Chemicals Group believes that consistently managing chemical products, reducing GHG emissions, managing water resources (effluent quality, water intake/discharge volumes), and controlling substances released into the air helps conserve biodiversity. In addition, we think increasing products and services with high environmental contribution standards reduces environmental burdens at each stage of product lifecycles and, in turn, helps conserve biodiversity.

Initiatives Aimed at the Basic Approach to Biodiversity Conservation (1)

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. In fiscal 2017, we conducted surveys of ecosystems surrounding parent company plants as well as production facilities of affiliated companies eligible for Responsible Care support. Using IBAT,* these surveys confirmed the absence of nature protected areas (i.e. world heritage sites, IUCN Category I, II, III, Ramsar Convention on Wetlands) within a 3km radius around these production facilities.

Integrated Biodiversity Assessment Tool. Developed jointly by BirdLife International, Conservation International, International Union for Conservation of Nature (IUCN), United Nations Environment Programme(UNEP), and UN Environment World Conservation Monitoring Centre, IBAT facilitates access to basic data and the latest information on natural preservation.

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 reduce CO2, protect resources, and harmonize with nature are designated as Blue Value products. Setting Blue Value product net sales ratios as a KPI in the 2025 Long-term Business Plan, we aim to expand products that help conserve biodiversity.

The Mitsui Chemicals Group complies with the regulations of individual countries in accordance with the Convention on Biological Diversity.

Regarding the procurement of raw materials, we make every effort to select raw materials and suppliers that have minor environmental burdens in accordance with our purchasing policy. During the distribution process, we work to reduce environmental burdens 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.
On January 22, 2010, the Group signed up to the Japan Business Federation's (Keidanren) Declaration of Biodiversity as a Promotion Partner. This means that the Group supports the seven principles set out in the declaration and that we commit to taking the initiative in our business activities and acting in accordance with the declaration and accompanying action policy.

Honshu Chemical Industry Co., Ltd.
Participating in Wakayama Prefecture's Company forest scheme

As part of its environmental activities, our affiliate Honshu Chemical Industry Co., Ltd. signed a Forest Conservation and Management Agreement with Wakayama Prefecture and Hidakagawa Town on September 7, 2010, with the aim of participating in Wakayama Prefecture's Company Forest conservation scheme.
As part of the Company Forest scheme, Wakayama Prefecture, forestry cooperatives, and companies work in partnership to effectively harness the prefecture's rich natural environment and get local people involved in environmental preservation.
In November 2010, Honshu Chemical Industry held a tree-planting event. As part of this event, employees and members of their families planted approximately 1,500 trees on a 1.32-hectare area of forestland in Hidakagawa Town (Hidaka-gun, Wakayama Prefecture). The forest was also given the official title "Hidakagawa Honshu Chemical Industry Forest."
On July 29, 2017, 33 people from the company participated in the cutting of weeds at the Hidakagawa Honshu Chemical Industry Forest under the guidance of the Kichu Forestry Cooperative, which has been entrusted with the forest’s local management.

Wildlife Survey on Rice Fields

The Mitsui Chemicals Group affiliate company, Mitsui Chemicals Agro, Inc. (MCAG), has been conducting a “Wildlife Survey on Rice Fields” using MCAG products since 2012.
Involved in the manufacture and sales of agrochemicals and fertilizers, MCAG conducts the “Wildlife Survey on Rice Fields” annually with the full support of customers, confirming that a wide variety of wildlife inhabit rice fields. MCAG surveys the effects of agrochemical use on wildlife in rice paddies, which leads to the improvement and development of products. Further, through the release of experts’ written opinions that summarize the results of these wildlife surveys, we certify that rice was grown in rice paddies inhabited by a wide variety of wildlife, which contributes to adding value to local rice.

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.

Mangrove afforestation by a Thai affiliate

In December 2017, the Company’s affiliate THAI MITSUI SPECIALTY CHEMICALS CO., LTD. (TMSC) planted mangrove trees in Chonburi province, where TMSC’s production facilities are located. Cooperating with the Mangrove Conservation Learning Center, TMSC undertook mangrove afforestation activities for the second time, with roughly 80 TMSC employees planting around 1,500 mangrove trees.
