Climate Change Countermeasures

Reducing Energy Consumption and GHG Emissions

IHI is constantly striving to use energy more efficiently and further reduce its CO2 emissions. The aim for FY2018 is to cut energy consumption per unit of consolidated sales (Energy intensity) by at least 3% compared to FY2015. To achieve this target, IHI is introducing energy-saving equipment and holding in-house lectures where outside experts teach employees about, for example, energy-control procedures for improved energy management.
In FY2016, our energy intensity was 10.4 (crude oil equivalent, kiloliter/100 million yen), a 4.0% increase from FY2015. In FY2016, our CO2 emissions was 317,000 tons*, down 2.7% from FY2015 CO2 emissions per standard physical unit went up by 0.9% to 21.3 (t-CO2/100 million yen). In FY2017, we will aggressively push forward with initiatives to achieve targets for both energy consumption and CO2 emissions.

* The emissions coefficient by electricity retailer was used to calculate CO2 emissions based on electricity consumption.

Reducing Energy Consumption in Transportation

In our IHI Group Environmental Action Plan 2016, we have established a target of reducing energy consumption during transportation of products, etc. by at least 1% compared to the previous fiscal year.
In order to reduce the energy consumption during transportation, we are actively promoting a modal shift to domestic vessels and slipways. Trucks are used for products, etc. which cannot be transported by ship and, in order to increase transportation efficiency, trucks with larger maximum load capacities are used and other initiatives are made to improve load capacity.

Building Recycling Societies

Improving Waste Management

IHI reduces, reuses and recycles (“3 Rs”) industrial waste and appropriately disposes whatever remains. Since FY2012, all IHI offices and works have been using an electronic manifest to comply with waste-management laws and regulations.
In FY2015, IHI compiled the Manual for Handling Wastes and improved its waste management level by enforcing management in accordance with this manual. In FY2016, a meeting to exchange opinions relating to waste was held between our headquarters and individual district business sites and issues relating to waste risk were shared.
Moreover, the IHI Group segregates the waste emitted from its business activities, then recycles and converts to valuable materials as part of efforts to reduce waste emissions. The target for FY2018 is to reduce the amount of waste emitted per unit of sales (waste emissions intensity) by at least 3% compared to FY2015. In FY2016, the amount of waste emitted was 30,531 tons. The waste emissions intensity for FY2016 was 2.05 (tons/100 million yen), a 0.5% increase compared to FY2015. IHI will continue its efforts from FY2017 onwards in order to achieve our waste emissions intensity target.

Appropriate Management of Toxic Waste

Since FY2009, IHI has been detoxifying electric equipment containing highly concentrated polychlorinated biphenyl (PCB). As of FY2016, detoxification had been completed on 98% of such equipment.
The same processing has been completed for 55% of low-concentration PCB and 56% of stabilizers and we plan to complete processing for all except difficult-to-process substances by the end of FY2018.

Reducing Water Consumption

IHI works to prevent leakages from water-supply pipes, industrial-water pipes and drainage pipes, many of which are buried within plant sites and are deteriorating due to age.
Renewal plans spanning several fiscal years are established for deteriorated buried pipes at each plant. New countermeasures are taken when renewal work is performed, such as running new pipes aboveground to enable potential leaks to be swiftly discovered, installing pipes in buried boxes or running pipes overhead using supports.
To reduce water consumption, the target for FY2018 is to reduce consumption per sales (water consumption intensity) by 3% compared to the previous year. In FY2016, water consumption totaled 4,169,000 m3 and the water consumption intensity was 0.280 (1000 m3/100 million yen), which was a 4.1% increase over FY2015.

Lowering Environmental Risks

Environmental Measures Near Worksites

Water Pollution Prevention

IHI monitors the quality of wastewater discharged from plants, one of many ways it protects public waters (oceans, rivers, etc.) at wastewater discharge points. The deterioration of treatment equipment, devices, instruments, etc. is noted during daily maintenance and environmental risks are assessed to determine renewal priorities. The results of these assessments are visualized in environmental risk-reduction plans.
Every year, the head office sets aside a special budget for environmental activities, after which allocations for renewals in the following year are determined to enable the responsible department at each plant to conduct renewal work in an orderly manner. In addition to environmental risk countermeasures, the special budget covers measures for removing and renewing (excluding disposal) equipment containing PCB, as well as energy-saving measures and global warming countermeasures.
Water pollution measures in FY2016 included evaluations of wastewater treatment facilities at the Aioi and Soma worksites, based on which plans were drawn up for necessary renewals in FY2017.

Soil Contamination Prevention

Contamination of soil can adversely affect the health of humans and other organisms through direct or indirect intake of hazardous substances.
Worksites are inspected regularly and aging equipment is renewed to avoid any leakage of hazardous substances. A survey of 25 hazardous substances* at 68 former and current production facilities was completed in March 2013. The survey results are compiled in a database.

*including lead, hexavalent chromium and mercury, which are listed in Article 2 of Japan’s Soil Contamination Countermeasures Act

Chemical Substances in Products

Appropriate Management

IHI has appropriate procedures for handling products that contain chemical substances.

IHI Group Basic Policy for the Management of Products Containing Chemical Substances

To enhance the competitiveness of its products and services, we have a Basic Policy for the Management of Products Containing Chemical Substances as shown below

〔Basics of activities〕
We identify prohibited and controlled substances that are restricted by laws and regulations in countries where it sells products and services, as well as in accordance with customer requirements.

Such products are appropriately assessed and managed throughout the entire supply chain. IHI is working on developing systems for conveying such information to customers in an appropriate manner.
Based on advice from an external specialist, chemSHERPA was introduced to communicate information on chemical substances in products for agricultural machinery.
Similar systems for other products will be introduced in accordance with customer requests.

Release and Transfer of Chemical Substances

IHI also monitors each worksite’s release of designated chemical substances into the atmosphere, public waters, soil, etc., or transfer to off-premises locations. This is done in accordance with the Pollutant Release and Transfer Register (PRTR), and the Japanese government is notified accordingly (see table).
The release and transfer of Class I Designated Chemical Substances in FY2016 were as follows.

Biodiversity Protection

Initiative Policies

Global Effort

The Japanese government introduced its National Biodiversity Strategy in 1995, which was followed by the enactment of the Basic Act on Biodiversity in 2008 to urge participation by businesses. In 2010, the International Year of Biodiversity, the 10th Conference of Parties (COP 10) was held in Aichi Prefecture, Japan. The Strategic Plan of the Convention of the Biological Diversity, or the Aichi Target, which was adopted at COP 10, describes a course of action for interested parties at all levels, including corporations, to practice sustainable production and consumption, as well as a rationale for putting concrete measures into practice.
In recent years, to achieve the Aichi Target adopted in 2010, the National Biodiversity Strategy 2012-2020 obtained Cabinet approval in September 2012. The Strategy presents a roadmap for Japan to achieve the Aichi Target as well as establishes “Five Basic Strategies” (*) as the directions for policies to be focused on up until FY2020.

  • * “Five Basic Strategies”
  •    (1) Permeate biodiversity throughout society
  •    (2) Review and rebuild human-nature relationships in regions
  •    (3) Secure connections between forests, mountains, rivers and oceans
  •    (4) Act with the entire world in mind
  •    (5) Strengthen scientific foundation and connect with political strategy

Protecting Biodiversity

IHI is undertaking a number of initiatives to protect biodiversity in the face of urban development in Japan and other areas of the world.

■Basic Stance
The IHI Group Basic Environmental Policy sets out the group’s stance regarding environmental protection. Recognizing the impact that its business has on the environment, IHI strives to reduce any burden and to protect biodiversity. Each IHI office and works carries out activities in conjunction with their surrounding communities.
Going forward, IHI will further strengthen awareness of biodiversity among its executives and employees, as well as further protect biodiversity and environmental sustainability through its business and philanthropic activities.

■Selected initiatives
・Replacement of non-native species with native species on IHI premises
・Creation and maintenance of biotopes on IHI premises
・Organizing tours of green preserves on IHI premises
・Engaging in activities to conserve forests

Aichi Worksites

In Chita, Aichi Prefecture, where Aichi worksite is located, 54% of the city is covered with woodland, lush greenery in an industrial zone and parks. The Aichi worksite has its own green preserve measuring nearly 70,000 m2.
The worksite also conducts nature watches for local residents and the planting of native plants by university students.
For information on detailed activities, please see below.

Recent Activities (FY2010-12)

In FY2010, IHI investigated if the Aichi worksite’s vast green belt could be used for conserving biodiversity. It was determined that the green belt was in fact the central point of an ecosystem connecting the local mountains and sea.Moreover, the existence of over 33 species of living creatures was confirmed, including mammals such as raccoons, birds such as kingfishers and Japanese pygmy woodpeckers, insects such as the Dorcus rectus beetle and eastern pale clouded yellow butterfly, proving that the area helps to maintain biodiversity. Accordingly, a study was conducted to determine the policy and tasks for green belt management, after which initiatives were introduced to vitalize the area as part of the surrounding ecosystem so that various animals could inhabit and travel through it.

Since 2011, IHI has held many events aimed at teaching the importance of nature by enabling people to come in close contact with diverse flora and fauna, including observing plants and gathering insects at the Aichi green belt.
In December 2011, the “Inochi wo tsunagu ("Connect Lives") Project,” a workshop for university students, was held at the green belt. The project connects the green belts of companies located along the Chita Peninsula coastline (Tokai and Chita cities) to form a large ecosystem. It also is attracting people to assist in this initiative through forums held in the green belts and environmental-maintenance programs in model zones. The Aichi worksite is collaborating with nearby companies, universities and government departments to support this activity by providing its green belt as a place for activities.
The workshop was led by the Ecologist Support Association of Japan, an NPO in charge of this project, and attracted 23 university students, etc. from Aichi and Mie prefectures. The students engaged in activities such as observing wild birds and maintaining the green belt area. After the workshop, the students conducted a study on how the company green belts could be used to form a rich ecosystem on the Chita Peninsula. They also compiled a free handout and ecosystem map of the green belts.
This project’s activities of protecting the natural environment, raising environmental awareness and developing people to continue such activities for the next generation were highly regarded and officially recognized by being awarded the “Grand Prize” of the Aichi Environmental Award and the Judge’s Special Award as part of the Good Life Awards sponsored by the Ministry of the Environment.

Recent Activities (FY2013-16)

As part of efforts to replace nonnative trees with native species in the Aichi green belt, IHI has set up a nursery to grow tree seedlings, and in FY2014, a gathering was held at the nursery to plant the seedlings. Members of the student executive committee of the Inochiwotsunagu ("Connect Lives") Project began the event by sharing knowledge on native and nonnative trees.
Every year since FY2012, the Aichi worksite has hosted “LOVE! GREEN DAY,” an event organized by the Ecologist Support Association of Japan, the NPO in charge of the Inochiwotsunagu Project. Through such undertakings, the green belts of companies on Chita Peninsula coast are opened to the public. At the Aichi worksite, participants planted native species such as enoki mushroom and Japanese zelkova in planters called kaminekon made from recyclable cardboard. They also enjoyed observing water creatures such as numachichibu dragonfly larvae and diving beetles in a biotope. Later, their feedback included remarks such as “I realized for the first time that there are many creatures living on the plant premises” and “I want to see many more kinds of creatures.” IHI will continue working to maintain its Aichi worksite green belt as a place of respite and study for members of the public and employees.
