Pollution Prevention

Policy and Basic Approach

As economic development progresses around the globe, pollution issues such as chemical spills, water pollution and soil contamination, air pollution resulting from hazardous waste, and ocean pollution have become serious issues. In response, countries around the world are advancing preventive measures and formulating various standards and laws. Sojitz believes that it is extremely important to reduce its environmental impact and conserve the environment by preventing pollution, curbing waste, recycling, and reusing resources as part of its corporate responsibility in the course of its business activities.

For Sojitz Group, which is engaged in a variety of businesses around the world, including handling various chemicals and materials, preventing pollution is one of the most fundamental and critical aspects of ensuring the sustainability of our businesses. Sojitz Group promotes a wide variety of initiatives related to pollution prevention with the aim of fulfilling its responsibility to society.

One of Sojitz’s Key Sustainability Issues (Materiality) is to “contribute to the global environment through our businesses.” As a component of these efforts, Sojitz "strives to preserve the environment and create businesses that are both highly competitive and environmentally friendly by pursuing environmental sustainability in its businesses.” Furthermore, as outlined item 3, “Minimize Environmental Burden” and item 5, “Consider the Environment in New Businesses” of Sojitz’s Environmental Policy, Sojitz will work to "reduce the burden on the environment and prevent pollution.”

Goals and Targets

Pollution Prevention

In its chemical business, Sojitz Group aims to (1) comply with relevant laws and regulations concerning various chemical substances, (2) prevent accidents by promoting safety management, and (3) conduct corporate activities and actions in consideration of the environment. In order to ensure that there are no omissions in the handling of chemical substances at related business sites, we have created manuals with specific procedures. These manuals stipulate the guidelines for handling chemicals, the relevant laws to be observed, and how to deal with hazardous substances.

In addition, we strive to prevent accidents from occurring and to minimize damage in the event of an accident by establishing systems to manage chemical substances and for responding to emergencies.

Compliance with Environmental Laws and Regulations

We remain apprised of the applicable laws and regulations to regularly confirm compliance conditions not only at Sojitz Corporation, but also at our Group companies. Internal audits of our Group companies also include checks on these compliance conditions.

Promoting Employee Awareness

We will make this policy known to all executives and employees, and continue to carry out educational and awareness-raising activities.


The Sustainability Committee discusses the formulation of company-wide policies and targets related to sustainability, including pollution prevention, the establishment and maintenance of systems to implement these policies, and monitoring various measures that utilize the ISO 14001 environmental management system standard. The Sustainability Committee reports to the Management Committee and Board of Directors, and receives supervision and direction from the Board of Directors.

In addition, the Finance & Investment Deliberation Council, which deliberates investments and loans, checks individual proposals for their relevance in terms of sustainability and environmental and social (human rights) risks. Furthermore, the Corporate Sustainability Office, a dedicated body, is in charge of monitoring the policies and targets formulated by the Sustainability Committee, as well as environmental and social (human rights) risks.

Systems to Promote and Implement Sustainability

Risk Management Systems

Environmental and Social Risk Management in New Business

  • Prior to deliberating on new investment and loan projects, we require the department applying for investment and loan approval to complete an “Environmental and Social Risk Checklist.” Using the checklist, the department confirms that they have conducted the required due diligence and taken all necessary measures to deal with potential environmental risks, such as soil, groundwater, or water contamination.

Monitoring Existing Businesses

Through external and internal analysis, we identify business areas that pose a high risk of environmental and wastewater pollution from among Sojitz Group businesses, including Group companies (consolidated subsidiaries and holding companies) and business partners, and analyze where environmental and social issues are generally prone to occur throughout entire supply chains from upstream to downstream. Moving forward, we will implement the PDCA (Plan-Do-Check-Action) cycle for risk response based on third-party opinions from external experts, maintain a high level of awareness of environmental issues throughout the Group, and strengthen our initiatives for identifying new risks.

In addition, Sojitz Corporation has acquired ISO 14001 certification, the international standard for environmental management. We will also conduct monitoring from the perspective of our pollution prevention efforts.

ISO14001 Monitoring

Confirming Compliance with Laws and Regulations

We confirm that all Sojitz departments and target Group companies comply with the laws and regulations related to chemical substances and anti-pollution measures, such as RoHS regulations, REACH regulations, and industrial waste laws. Sojitz’s president serves as the chair of the Sustainability Committee, which confirms issues such as whether Sojitz is in compliance with these anti-pollution laws and regulations, and carries out management reviews to provide corrective instruction.

Establishing Action Plans for Departments and Offices

The policies and items resolved by the Sustainability Committee and reported to the Management Committee and Board of Directors are made known to employees not only through the company intranet, but also through regularly held briefing sessions with each department, organized by the Sustainability Committee secretariat.

Items resolved by the Sustainability Committee are established by each department and office at the beginning of the period. These consist of 1) environmental impact of business activities around the world, and an analysis of related laws and regulations; and 2) goal setting and action plans to mitigate these environmental impacts, including those related to pollution prevention. These items are reviewed by each department and office every six months, and the results of these reviews are evaluated by the Sustainability Committee and reported to the Management Committee at the beginning of the following year.

Safety Management in the Chemicals Business

The Chemicals Division implements the following safety management system in line with the aforementioned policies and targets set out by Sojitz Group.

Compliance with Chemicals Management Regulations and Sojitz Safety Initiatives

The Chemicals Division has established a set of policies regarding the handling of chemicals that includes the Chemicals Management Guidelines and the Chemicals Management Regulations—a document created in accordance with current chemicals-related laws and regulations. The Chemicals Division maintains the following records and keeps division members informed regarding their content: an organizational chart for the Sojitz chemicals management system, a record of all approved chemicals, a registry of employees bearing legal liability in chemicals-related matters, and an emergency contact chart.

The Chemicals Division ensures compliance with a wide range of laws and regulations designated by environmental management systems including Japan’s Chemical Substances Control Law, Industrial Safety and Health Act, PRTR Act, Poisonous and Deleterious Substances Control Act, Fire Service Act, and High-Pressure Gas Safety Act.

Sojitz notifies its business partners regarding hazardous chemical products through Safety Data Sheets (SDSs), which are issued for each chemical handled within Sojitz supply chains. SDSs are included on the label of every chemical product, and Sojitz communicates with business partners as appropriate regarding hazardous materials. SDSs also include information regarding relevant environment protection-related laws and regulations including the PCB Special Measures Law, Fluorocarbon Emissions Control Act, Water Pollution Prevention Act, Soil Contamination Countermeasures Act, Air Pollution Control Act, and Offensive Odor Control Law.

No violations of environment-related laws and regulations were reported within Sojitz Group in FY2022.

Disclosure of Chemical Content and Centralized Management of Relevant Laws and Regulations

The Chemicals Division maintains a lists of the CAS numbers and chemical content by percentage found on the SDS for each product handled by Sojitz Group. In the event that relevant laws and regulations such as the Industrial Safety and Health Act, PRTR Act, or Poisonous and Deleterious Substances Control Act undergo revision and cause new chemicals to become subject to regulation, Sojitz’s centralized management system allows the Chemicals Division to quickly identify which products contain the newly regulated chemicals and comply appropriately.

The centralized management system features an at-a-glance view of the relevant laws and regulations listed on each product’s SDS, and employees can also view the product codes for all products subject to a specific law. This structure ensures Sojitz’s full compliance with all laws and regulations.

Chemicals Management Training

Based on the aforementioned policies, Sojitz Group implements various initiatives to prevent pollution as describe below.

Initiatives at NI Chemical Corporation

  • NI Chemical Corporation is a Sojitz Group subsidiary involved in the chemical and oil tank leasing business. The company also stores toxic and hazardous materials, primarily including flammable liquids. These are some of NI Chemical’s anti-pollution measures and environmental initiatives.

1) VOC Measures

  • Volatile organic compounds (VOC) impact the level of photochemical oxidants (*1), and NI Chemical uses a device to collect VOC to reduce emissions into the atmosphere.
    VOC collected: FY2019(67 tons), FY2020 (79 tons), FY2021 (83 tons)

    (*1) Photochemical oxidant is the general term given to substances created by a photochemical reaction that occurs when VOC or other compounds are hit by ultraviolet rays from the sun. If the concentration of photochemical oxidants rises, it can result in photochemical smog, or white, mist-like air that can cause irritation to the eyes or throat and other health hazards.

2) Management of Hazardous Waste

  • When cleaning tanks, hazardous waste is at times present, including certain chemicals that are highly flammable. Hazardous waste is stored in a specific storage area that follows all waste regulations pertaining to storage, management, and disposal.
    In terms of the Waste Management and Public Cleaning Law, NI Chemical is required to submit an industrial waste disposal plan that includes the disposal of hazardous waste as well as submit its disposal records. The company monitors waste management according to this plan and reports to the government. Additionally, NI Chemical implements innovative measures for tank cleaning as well as ways to reduce residue buildup that would require cleaning in order to minimize the production of industrial waste.

3) Installation of Oil Fences

  • NI Chemical transfers chemical raw materials owned by its customers from tanker ships to tanks on open water. In the unlikely event of a chemical spill, NI Chemical has an oil fence installed on-site to prevent sea pollution.
    NI Chemical has also established a joint organization to prevent maritime disasters, and in the unlikely event of an accident will make use of the organization’s oil boom extender.
    NI Chemical has no record of ocean pollution or pollution incidents to date.

4) Establishment of a joint maritime disaster prevention organization with neighboring companies

  • Disaster drills are held regularly.
    Partnering with neighboring companies, NI Chemical has established a joint maritime disaster prevention organization, which regularly holds joint drills that include flood control and other practices to strengthen its disaster prevention capabilities.

    This joint organization owns two fire engines and has three people stationed on duty at all times throughout the year.

5) ISO9001

In order to maintain quality control, safety standards, and efficient handling of chemical products, NI Chemical obtained ISO9001: 2015 certification and strives to maintain certification for 20 years.
