Environmental Report
Reducing the Environmental Burdens through Business Activities


IHI works continuously to lower its environmental impact by reducing the amounts of materials it uses and generates in its operations. The “material balance” in IHI operations in FY2015 is shown below.

Cutting Energy Consumption and CO2 Emissions

IHI is constantly striving to use energy more efficiently and further reduce CO2 emissions. The aim this year is to cut energy consumption per unit of consolidated sales (energy consumption per standard physical unit) by 1% compared to FY2014. 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 FY2015, IHI’s energy consumption per standard physical unit was 10.0 (crude oil equivalent, kilo-liter/100 million yen), a 2.9% reduction from FY2014. Although energy consumption has been increasing since FY2012, energy consumption per standard physical unit has been decreasing thanks to energy-saving efforts. In FY2015, IHI’s CO2 emissions was 297,000 tons, up 0.5% from FY2014, and its CO2 emissions per standard physical unit was 19.3 (t-CO2/100 million yen), down 4.9%.

Reducing Energy Consumption in Transportation

Transportation-related initiatives are targeted at reducing energy consumption by at least 1% annually.
For example, when aero engine parts manufactured at the Soma No. 1 and No. 2 Aero-Engine Works are sent for assembly at the Kure Aero-Engine & Turbo Machinery Works, the company now uses larger trucks, consolidates diverse products in one truck and runs trucks more regularly.
Also, a deck crane manufactured at the Aichi Works is transported by a salvage barge. In addition, roll-on/roll-off (RO-RO) ships are being used more often because vehicles can be driven directly on and off the ship for enhanced efficiency.
Through such measures, IHI is intensifying efforts to visualize the amount of energy it expends to transport products at each works. Also, the data is reported regularly to the Group-wide Environment Committee chaired by the board member in charge of the environment.

Building material-cycles societies

Improving waste management

IHI reduces, reuses and recycles industrial waste—the 3Rs—and appropriately disposes it as required. Since FY2012, all IHI offices and works have been using an electronic manifest system to comply with the laws and regulation of waste management. In FY2015, IHI introduced the Manual for Handling Wastes, which is helping to raise in-house understanding of how to manage waste effectively.

Waste emitted by IHI

IHI segregates and recycles selected waste to increase its value. In FY2015, the company emitted 31,394 tons of wastes, the same level as FY2014.

■ Waste Generated on Consolidated Basis

Water Consumption

IHI is striving to cut its water consumption by reusing more water, including drinking water, industrial water and groundwater. IHI also is working hard to cut its water emissions to rivers, seas and sewerage. IHI consumed 4,148,000 m3 of water in FY2015, down 0.5% from FY2014.

■ Water Consumption on Consolidated Basis

Management and Disposal of PCB contaminated equipment

Since FY2009, IHI has been detoxifying electric equipment containing highly concentrated polychlorinated biphenyl (PCB). As of FY2015, detoxification had been completed on 97% of such equipment and 29% of all capacitors.

Addressing Soil Contamination

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

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

Information on Chemical Substances in Products

Chemical Substances and Pollutant Release and Transfer Registers (PRTR)

IHI is developing a system to manage chemical substances contained in IHI products. We cooperate with suppliers to provide customers with information about chemical substances contained in our products in a timely manner.
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 government is notified accordingly. The table below compiles the release or transfer of Class I Chemical Substances designated by the PRTR Act.

Biodiversity Protection

Global Effort

The Convention on Biological Diversity was signed at the United Nations Conference on Environment and Development (Earth Summit) in 1992 for the main purpose of protecting biodiversity. In 1995, the Japanese government introduced its National Biodiversity Strategy, followed by the enactment of the Basic Act on Biodiversity in 2008, which urge businesses to partake in biodiversity protection. 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, adopted at COP 10 describes a course of action for interested parties at all levels, including corporations, to practice sustainable production and consumption, and presents the rationale for putting concrete measures into practice.

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.

■IHI’s Stance

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.

The program has demonstrated to the rest of Japan that Aichi is one of the most environmentally friendly prefectures in the country. The IHI worksite’s Life Relay Project, which was recognized as a pioneering model for protecting local ecosystems, is now having a ripple effect in other regions of the country.

■Nature Watch Organized by Chita City

Participants observing insects and plants

An event entitled “Nature Watch? Let's Look for Autumn Insects” was organized by Chita City in September 2012 to provide local residents with a closer look at the insects and plants living in the Aichi worksite’s green preserve. The nature watch, which was attended by 48 local residents, allowed participants to experience ecosystems and even catch insects to observe them up close.

■Corporate Green Preserves Opened to Public

Love Green Day 2012 participants

“Love Green Day 2012,” an event organized by the nonprofit Japan Ecologist Support Association, which is associated with the Life Relay Project, was held in December 2012. Green preserves owned by businesses in the Chita Peninsula area were opened to the public for the event. The IHI Aichi worksite organized a project to plant seeds of native tree species, enoki and keyaki, in pots made of recycled cardboard.

■ Activities in FY2011

■Workshop Organized by Life Relay Project

Workshop organized by the Life Relay Project

In December 2011, the Life Relay Project organized a workshop for university students in the green preserve of IHI’s Aichi worksite. A total of 23 university students from Aichi and Mie prefectures attended the workshop conducted under the guidance of the nonprofit Japan Ecologist Support Association, which is associated with the Life Relay Project. The students observed wild birds in the worksite’s green preserve and learned about maintaining such eco-assets. They also discussed the findings of a survey about preserves that businesses are holding to help protect ecosystems on the Chita Peninsula. Another project was to compile a free guide and ecosystem map featuring corporate green preserves.

■Environmental Activity for IHI Employees and Children
IHI organized an environmental activity-Fun with the Environment - Let's Play and Learn in the Woodland Created by the Sea-for company employees and their children in September 2011. The event provided opportunities for the participants to observe about wildlife living in the IHI Aichi worksite green preserve and learn the importance of nature.

In FY2011, the IHI Aichi worksite began examining how to put its green preserve to practical use in terms of protecting biodiversity. It conducted an analysis of the surrounding ecosystem, of which the green preserve is one part, aiming to ascertain what roles the preserve serves now and what would be possible in the future from the perspective of biodiversity. Satellite imagery was used to evaluate the preserve and create a map to visualize how it connects with the surrounding area. It was learned that it is part of a larger ecosystem that links woodland on one side and the sea on the other, with the preserve forming the center of this natural network.

Also, a study of the worksite and neighboring area conducted in October revealed a range of animal species living in the preserve, including tanuki raccoons, kingfisher and pygmy woodpeckers, stag beetles, colias butterflies and much more. The findings were identical to those of surveys conducted in the surrounding area.
