Environmental Management
Basic Approach
SHI Group recognizes that conservation of the global environment and climate action are issues that are to be prioritized in our effort to realize a sustainable society, and we endeavor to reduce our environmental impact across all operations, including the entire lifecycle of our products, in accordance with our Sustainability Basic Policy.
SHI Group Environmental Policy
SHI Group established the Sumitomo Heavy Industries Group Environmental Policy in November 1999, expanding environmental management across the Group as a whole, including overseas facilities, in order to clarify the basic policy for activities throughout our Group.
Recently, human activities have had an increasingly severe impact on biodiversity due to climate change, land use changes, resource overexploitation, invasion of non-native species, and pollution. Companies are expected to take action responsibly to conserve and restore biodiversity.
Along with addressing climate change and other global environmental challenges, we revised our Environmental Policy in July 2025 out of the recognition that conservation and restoration of biodiversity are essential components of a foundation supporting the sustainability of social and economic activities
- 1SHI Group will work to conserve the global environment and endeavor to prevent environmental pollution.
- 2At each stage along the supply chain, SHI Group will reduce carbon dioxide emissions and waste, reuse and recycle water and other resources, and use energy more efficiently as part of our commitment to promote initiatives to reduce our impact on the environment and realize a circular society.
- 3In our business activities and throughout the entire supply chain facilitating these operations, SHI Group will appropriately ascertain our dependence and impact on natural capital and ecosystem services as well as evaluate the attendant risks and opportunities, then endeavor to contribute to restoration of the natural environment in addition to conserving and restoring biodiversity.
- 4SHI Group will strengthen our environmental management structure and continue to operate and improve our environmental management system.
- 5SHI Group will not only comply with environmental laws and regulations but we will also establish and apply voluntary standards to assess our environmental performance as needed.
- 6SHI Group will work, through ongoing education and awareness activities, to raise the awareness of everyone involved in our business activities about environmental conservation, biodiversity, and natural capital.
- 7SHI Group will strive to disclose this Environmental Policy, appropriately share relevant information, and work closely with employees, customers, shareholders, suppliers, business partners, local communities, and all stakeholders.
Promotion of Environmental Management
We are committed to environmental management. Every three years since FY2005, we have formulated medium-term environmental plans that set out specific activity targets.
Environmental Management Structure
Management of SHI Group-wide environmental activities is implemented by the General Manager of the General Administration Group and the Environmental Management Division under the supervision of the Officer in Charge of General Administration who is appointed by the President. As the person with ultimate responsibility, the President approves and determines SHI Group's Environmental Policy.
Environmental audits are conducted in conjunction with local status checks to verify the status of environmental management at all manufacturing sites including those of affiliated companies, and the results of these activities are reported and problems shared at environmental management meetings. In addition, environmental education is provided to inform our employees of SHI Group's Environmental Policy, environmental targets, and initiatives.
Activities
- Environmental audits (once/year)
- We audit our manufacturing sites in Japan, China, and Southeast Asia to assess overall environmental management from the perspectives of environmental incident prevention, legal and regulatory compliance, and global warming prevention.
Audit results are evaluated on a five-point scale for each division based on our own evaluation standards, and reported to the Executive & Operating Officers Meeting for improvement.
- Examinations by General Administration Group General Manager (as required)
- In conjunction with environmental audits, the General Manager of the General Administration Group conducts a separate examination and provides guidance to those divisions that the General Manager deems necessary (such as divisions where environmental incidents occurred the previous year, divisions where environmental targets were significantly underachieved, etc.).
- Environmental management meetings (twice/year)
- Environmental Management Meetings are held for works and affiliated companies in Japan to report activity results and share problems. China Environmental Management Meetings are also held for affiliated companies in China with the aim of raising the level of environmental activity performance of these companies.
- Regional activities
- In each region, intraregional meetings are held on the topics of global warming prevention, energy efficiency enhancement, and other themes. Reports are provided on activity progress, case studies presented, and other information shared.
Environmental Risk Assessments
SHI Group regularly conducts environmental risk assessments at each of our sites to preempt environmental incidents.
Additionally, if an environmental incident occurs, we take appropriate action and thoroughly analyze the incident as part of our efforts to prevent any recurrence as well as similar incidents involving comparable equipment or substances at other sites.
SHI Group operates in a manner that bolsters prevention of potential environmental incidents by addressing events that may someday trigger an environmental incident even though the event itself is not classified as such.
7th Medium-Term Environmental Plan
The 7th Medium-Term Environmental Plan establishes three material issues and promotes initiatives to address these with the aim of achieving SHI Group’s target of carbon neutrality by 2050. Single-year targets are also set and progress monitored.
- 1Reduce total CO2 emissions
- 2Reinforce environmental management
- 3Alleviate environmental footprint accompanying business activities

ISO 14001 Certification
SHI Group has been engaged in environmental activities based on the SHI Group Environmental Policy, and working to obtain certification at each of our works in Japan since 1998.
In 2018, we acquired unified certification for the SHI Group in order to integrate environmental management operational rules and make it more efficient to maintain certification.Currently, we have 44 sites that have been certified.
In addition, all our affiliated companies in Japan and overseas that are not included in the unified certification have acquired certification individually, and we are making every effort to ensure appropriate environmental management. In 1998, we also started acquiring certification for key manufacturing plants overseas. As of 2024, 26 of our sites have acquired certification.
Percentage of SHI Group with certification (based on number of locations): 86.1%
As we move forward, we will also review environmental activities as a challenge to be addressed in our business and promote such activities throughout the SHI Group.

Response to CDP
CDP Climate Change
CDP is a UK-based international non-governmental organization that collects and analyzes information on the environmental initiatives of companies and cities and publishes the results. It is the world's largest environmental survey, and each year it assigns an eight-level rating (A, A-, B, B-, C, C-, D, D-) based on the responses from companies.
The results of the CDP Climate Change Report are shown in the table below. We are working to improve our score by disclosing information in line with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and by enhancing non-financial information.
