The IHI Group has set compliance to environmental laws and regulations and the prevention of environmental accidents as the highest priorities of environmental activities in business. We have also set the reduction of the environmental impact from our business activities as a priority subject in our environmental targets designated for each Group site. We emphasize cooperation with the local communities in each region where IHI does business to advance environmental conservation activities according to the unique needs of each. These efforts include agreements to prevent pollution with local government agencies and residents.
Our plants and offices in particular are often located near water sources, which means initiatives to prevent any pollutants from reaching these water sources are imperative. Therefore, we have defined independent standards that go beyond the Water Pollution Control Law and other local governmental waste water standards based on the Environmental Management System (EMS) adopted at each site. We ensure that the standards are met through regular water sampling and analysis. In addition, the person in charge of drainage and coastlines at each site conducts regular patrols to visually inspect and make sure there are no oil or other floating chemicals or irregularities in water quality. In the event of any leakage of substances into waters from IHI plants or offices, our initial response follows EMS procedures to prevent any spread of the contaminants and damage, trigger an emergency response, including correspondence with relevant departments, in an effort to investigate the root cause and prevent recurrence.
In addition to the above, measures and proper disposal to prevent soil contamination from oil, chemical, and other leakage used at offices, plants, and other business establishments are also vital.
To improve the management level of these activities, we conduct regular internal audits, environmental patrols, and external reviews according to the EMS adopted by each site.

The IHI Group monitors the quality of water discharged from offices, plants, and other business establishments.
By defining and managing water discharge according to independent standards stricter than waste water standards, we protect the water quality of public waters from oceans to rivers where this water is discharged. We must not only maintain and rehabilitate waste water treatment facilities but also regularly renew aged equipment, devices, and meters.
The IHI Group also prioritizes measures to prevent leaks from unseen underground pipes as a key issue. Our other initiatives include measurements of the amount of water used in specific areas, creation of underground piping blueprints, and periodic replacement of underground piping.
We also define rules on chemical substance management based on the EMS at each environmental management center to prevent disasters and environmental pollution due to chemical substances used at plants and other business establishments. Our Group categorizes the hazardous, toxic, volatile, and combustible chemical substances it handles while defining equipment and handling standards to manage these substances in a way that prevents leakage into the environment.
The IHI Group identified specific areas at offices, plants, and other business establishments that use hazardous substances and other chemicals. We strive to prevent leaks of chemical substances by establishing operational procedures and periodic patrols. We manage 68 old factory sites and production bases via a database compiling survey results for the usage history of specific harmful substances* and oils. This survey data is used as a starting point for initial reviews when restructuring plant operations.
Harmful chemical substances refers to lead, hexavalent chromium, mercury, and other substances listed in Article 2 of the Japan Soil Contamination Countermeasures Act.
The IHI Group is furthering its response to properly dispose of hazardous polychlorinated biphenyls (PCBs) waste by organizing a specialized team led by the Head Office.
As of March 31, 2022, we have successfully disposed of 99.9% of electrical equipment containing high-concentration PCBs and 94.0% with low-concentration PCBs. However, the IHI Group currently holds a large number of fluorescent lamps waiting for disposal. To date, we have successfully disposed of 58.8%.
The IHI Group identifies and manages emissions of chemicals regulated by the PRTR Law into the air, public waters, soil, sewers, and waste and provides proper notifications in accordance with laws and regulations.
We are also suppressing emissions of Volatile Organic Compounds (VOCs) into the atmosphere in accordance with the Voluntary Action Plan for Establishing a Sound Material-Cycle Society by the Japan Society of Industrial Machinery Manufacturers.
The IHI Group strives to recover and preserve the surrounding environment through environmental protection activities driven by cooperation between offices, plants, and other business establishments and local communities. We also have set an environment month for officer and employee enlightenment to raise awareness about biodiversity conservation.
