In conducting business, we have put in place a system to ensure that utmost consideration is given to the environment and society in projects at all stages, including at the launch of a new business, during operations, and even during the exit stage.

ESG Risk Management

In our Chemicals Segment, we position chemical substance management as an important aspect of trade compliance alongside security trade control, to protect human health and safety, and to protect the global environment (specifically water, soil, air and the ecosystems of animals and plants). While taking into consideration the laws and regulations of peripheral business sectors such as pharmaceuticals and food products, we will update the information we have about chemical substance management laws and regulations so that we can keep abreast of increasingly tightening Japanese and international regulatory trends. In individual projects of each Business Unit, we consider their impact on the environment in advance, including measures to control toxic emissions, and take sufficient measures before going ahead with new business.

Chemicals can be dangerous or hazardous to the human body and the environment. In our Chemicals Segment, we comply with the following specific laws and regulations: the Act on the Evaluation of Chemical Substances and Regulations of Their Manufacture, etc. (CSCL); the Industrial Safety and Health Act; the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (laws concerning Pollutant Release and Transfer Register/PRTR); the Poisonous and Deleterious Substances Control Act; and the Fire Service Act. We also comply with a wide range of environmental management systems.
We comprehensively identify of all chemicals used by using the Globally Harmonized System (GHS) of Classification and Labelling of Chemicals.
We evaluate all raw materials from suppliers to understand if they need to be registered with government bodies, such as the Environmental Protection Agency (EPA) in the United States, and the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) program in the European Union, and take necessary actions to ensure such registrations.
We have prepared management and operational procedure manuals as part of our in-house regulations. Based on the provisions of each law and regulation, we inform our supply chain of chemical hazard information by providing safety data sheets (SDS) for all chemical products we distribute, and display this information on labels to ensure that people are properly notified.
In addition, in our Chemicals Segment, we have obtained certifications related to quality and safety management (e.g. ISO9001) at almost all of our production sites.

In our chemicals business, we have phased out all chemicals of concern prior to regulations and no longer handle any "substances that need to be phased out". We are contributing to the creation of codes of conduct for the chemical industry regarding the handling of chemical substances that need to be phased out. One specific example of this was our participation in prior consultations on the revision of the 2018 amended Ozone Layer Protection Law (amendment to the quantity allocation aimed at the reduction of manufacturing and amount of import of HFC substitutes) with the Fluoride Gases Management Office, Chemical Management Policy Division, Manufacturing Industries Bureau of the Ministry of Economy, Trade and Industry (which has jurisdiction over this Law) on the Trade Control Committee (for companies importing or exporting chemicals involving large sums of money) of the Japan Chemical Exporters and Importers Association.

There are no specific records of the introduction of substitutes for substances of concern in our chemicals business.

Evaluation of the hazards and toxicity of chemical substances is a social responsibility of all businesses that handle chemical substances, including Mitsui & Co. All products and raw materials that we handle are subject to such evaluations. While we are not a manufacturer, we maintain the recognition that the responsibility of an importer of chemicals distributed in the Japanese market is exactly the same as that of a Japanese manufacturer of chemicals.
All employees handling chemicals at Mitsui & Co. and its group companies are provided with regular training on laws and regulations related to the management of chemical substances, and on the Waste Management and Public Cleaning Law to ensure appropriate waste management practices. As a trader of chemicals, during the bimonthly training sessions we explain the need to communicate hazard and toxicity information correctly throughout the supply chain, and we set additional training themes based on frontline needs. Many people voluntarily participate in each session in our endeavor to communicate the importance of proper chemical substances management. By holding frequent in-house training sessions on the Chemicals Business Laws and on other topics, we continue to promote awareness of the evaluation of the hazards and toxicity of chemical substances as well as the appropriate labeling and display of information of such substances.

Any accident is promptly reported to the relevant units in accordance with our internal rules, and comprehensive steps are taken to prevent recurrence, beginning with the identification of the root cause of the accident and an assessment to determine appropriate corrective and preventive measures. In the fiscal year March 31, 2024, there was 1 environmental accident at Mitsui & Co. and its subsidiaries in Japan or overseas.

While 1 accident occurred, it was promptly reported to the relevant ministries, agencies, and local governments, we identified the root cause, and implemented an assessment to determine appropriate corrective and preventive measures. Thorough measures were then taken to prevent recurrence, and progress was publicly announced on the website of the subsidiary as needed.

As we work to accelerate environmental initiatives across the global group, it is vital that we raise the environmental awareness of each of our officers and employees at all levels. Through initiatives such as holding regular seminars and environment law training sessions, we work to raise awareness of environmental issues among officers and employees of Mitsui, its subsidiaries, and its affiliated companies. Furthermore, we also work on initiatives to gain specialized knowledge through ISO14001 Provisional Auditor Training and other programs.

Mitsui operates in compliance with the Waste Management and Public Cleaning Law (also referred to as the "Waste Disposal Law" or "Waste Law"). In order to properly manage the disposal of industrial waste generated through logistics operations and general waste from business activities, we have formulated a workflow in connection with the handling of industrial waste and general waste from business activities and prepared FAQ documents. Such tools and documents are utilized by relevant divisions and departments. We also hold periodic internal seminars to increase awareness and understanding of proper waste disposal practices, covering such matters as the selection of waste management subcontractors and manifest compilation and management.

In promoting business activities, Mitsui & Co. Group comply with environmental laws and regulations, including but not limited to the following. During the fiscal year ended March 2024, there was one report of violations of environmental laws and regulations. However, there were no major penalties or non-monetary sanctions imposed on our organization for violations of environmental laws and regulations.

Act on Special Measures Concerning Promotion of Proper Treatment of PCB Wastes/Act on Rational Use and Proper Management of Fluorocarbons/Water Pollution Prevention Act/Soil Contamination Countermeasures Act/Act on the Promotion of Sorted Collection and Recycling of Containers and Packaging/Act on Promotion of Recycling and Related Activities for Treatment of Cyclical Food Resources/Air Pollution Control Act/Offensive Odor Control Law/Poisonous and Deleterious Substances Control Act/Fire Service Act/Industrial Safety and Health Act/REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations.
