The Hitachi Group, with the goal of achieving a moresustainable society, is promoting global production that
reduces the environmental burden of products

Deepening environmental management
through dialogue with stakeholders
This Environmental Sustainability Report is newly prepared
to provide more detailed information on our environmental activities, which we have introduced in the HitachiGroup Corporate Social Responsibility Report. We believethat this will encourage deeper discussions with our
stakeholders and, in turn, strengthen our environmental
management. We look forward to further dialogue withyou through this report.
Since our long-term plan, Environmental Vision
2025, was released in December 2007, I have been explaining the philosophy behind that vision and Hitachi Groupactions to a range of stakeholders around the world. In
addition, we held a number of environmental forums inTokyo, Paris, Beijing, Washington, D.C., Singapore andelsewhere in fiscal 2008 to discuss environmental conservation and technology development with stakeholders. For me, what emerged from these forums was a great
sense of urgency from all concerned—governments, companies and consumers—and that concrete action must be
taken as soon as possible.
For global warming in particular, humankind’s expertise and commitment are being challenged by the need tohalt the increase in greenhouse gases for the world as awhole and change the trend of emissions into a downward2

trajectory within the next five to ten years. Water issues
too are reaching a crisis point in many places around theglobe. Therefore, we must face global environmental challenges with global-scale solutions. At the same time, anemerging social trend is to see environmental action as asource of economic growth and employment, making thisa growing market. Given these circumstances, I believethat Hitachi must work to realize a sustainable society
based on the Corporate Credo of contributing to society
through the development of superior, original technology
and products. I see promoting environmental management to attain this goal as the responsibility of the entire
Hitachi Group.

Using the Hitachi Group’s technologicalstrength for environmental protection
Based on our medium-term plan, Environmental Vision
2015, we are pursuing a two-pronged environmental
management strategy: reducing the environmental burden
through monozukuri and supplying environmentally conscious products and services. In addition, our long-term
plan, Environmental Vision 2025, sets the 2025 goal tohelp reduce annual CO2 emissions by 100 million tonnes
through Hitachi products and services with high environmental performance. For me, our dialogues with stakeholders have underscored the strong expectations they hold forthe development of new technologies and products thatwill contribute to achieving this goal. The stakeholders
have made me strongly aware of the major responsibility
that Hitachi bears in resolving global environmental issues.
Looking ahead, in the short-term, the Hitachi Groupwill focus on developing and distributing products that
achieve substantial energy savings. For this reason, we aremaking all our products Hitachi Eco-Products. Our longterm program concentrates on innovative technologies;
we will accelerate the development of environmentallyconscious and energy-saving products and services. We
will place special emphasis on a few core projects: nuclear
power generation, which emits very little CO2; renewableenergies and smart grids, for sustainable energy; and environmentally conscious data centers.
To remind employees that environmental protection
is everyone’s responsibility, we distributed Eco Badges infiscal 2008 to all Hitachi Group employees around theworld. Wearing these badges is a sign of each person’s
resolve to build environmental conservation into our daily
work and doing what we can to realize Hitachi’s environmental vision. Based on this personal awareness of every
member, we at the Hitachi Group will intensify our efforts
to realize a sustainable society through cooperation andTakashi Hatchojidialogue with stakeholders.

The quest for a comfortable existence has led humankind to create a highly convenient society. Today’s society, however,requires a vast amount of energy, and is causing problems, such as global warming, resource depletion, and environmental damage. We should challenge these common issues if we are to maintain a comfortable existence into the future.

through Hitachi products and services

2015

We are working to achieve emission neutral by fiscal 2015 by pursuing production that reduces the environmental burden of products
throughout their life cycle. Emission neutral means making the directenvironmental load and the reduction of the social environmental loadequal. Here, direct environmental load includes material production,
manufacturing, and transportation, while the reduction of social environmental load is the environmental load of finished products, after
delivery, which have been reduced with energy- and resource-saving
products (compared with fiscal 2005 reference products). We intend
to achieve emission neutral by reducing the environmental load of production activities, while at the same time improving the environmental
efficiency of products to reduce their environmental load.
The Emission Neutral Concept

We have set the long-term goal of helping to reduce annual CO2 emissions by 100 million tonnes by 2025 through Hitachi products andservices (base year fiscal 2005) by making and distributing productswith less burden on the environment. If no new measures are taken(status quo), world CO2 emissions in fiscal 2050 are expected to be
twice the fiscal 2005 level. To stem the increase in global warming,
CO2 emissions need to be cut further compared with the status quo
and we are supporting that goal by helping reduce emissions by 100
million tonnes per year by 2025.

Achieving the Medium-Term Plan: Environmental Vision 2015
The target of our medium-term plan, Environmental Vision 2015, isto achieve emission neutral by fiscal 2015 (page 7). Drawing on the
Sustainability Compass, which lays out directions for environmental
activities, we have developed an Environmental Action Plan with specificaction items and targets for fiscal 2010. Action items include expanding
our Eco-Product lineup, steps to counter global warming, efficient use ofresources, and proactive communication on environmental issues. The

GREEN 21 evaluation system, which quantifies that year’s Environmental
Action Plan targets, is used to gauge our progress, verify the results, andensure continual improvement.
The Environmental Action Plan is also optimized by adding action items
and reviewing targets in response to, for example, changes in the global
environment, requests from stakeholders, or early target achievement.

The goal of Environmental Vision 2025 is to help reduce annual CO2 emissions by 100 million tonnes by 2025 through our products and services
using our combined technological strengths (page 7). We aim to make all
products Hitachi Eco-Products.†1 We will also promote green technology,
business investment, and collaborative projects in global markets.
To reduce CO2 emissions, we plan to cut 70 million tonnes in electric
power generation, and 30 million tonnes in energy consumption, including
industry, transportation, and daily living (commercial and residential use).
For electric power, we will improve coal-fired technology, build nuclear
power plants—while expanding maintenance, repair, and other services—and stimulate renewable energy use with technologies such as batteries

and smart grids.†2 For industry, we will supply high-efficiency inverters andtransformers, while providing energy-saving services, and create powersaving data centers. For transportation and daily living, we will develop lithium-ion batteries for industry and cars, and reduce the energy consumptionof air conditioners, washing machines, and other home appliances.
†1 Eco-Products: Products that meet the standards set by the Assessment for DfE (Design forEnvironment) system, using criteria such as energy efficiency and resource recycling to quantify
the environmental load.

†2 Smart grids: Power distribution grids that integrate the conventional power infrastructure
and ICT technology to include renewable energy and other dispersed power sources efficiently
while maintaining reliable supply.

Environmental Load Information Collection Methods
The following standards and guidelines are used for determining the scope of the information collected on the Hitachi Group’s environmental load, for establishing base year
data, and for collating results.

Environment Information Item

Standards, Guidelines, Laws and Regulations, etc.

Energy• ISO 14064-1, which is based on the Greenhouse Gas Protocol (GHG Protocol) developed by the World BusinessCouncil for Sustainable Development• Manual for Calculating and Reporting Greenhouse Gas Emissions, Rev. 2.4 (Ministry of the Environment, Japan)

Waste products• Japan’s Waste Disposal and Public Cleansing Law• Flow of Industrial Waste Treatment (Ministry of the Environment, Japan)

Volatile organic compounds (VOCs) and chemical substances• Japan’s Pollutant Release and Transfer Registers (PRTR) Law

Environmental Load Evaluation System
The Hitachi Group’s environmental load evaluation system is used byaround 300 facilities in and outside Japan to determine the environmental load created by business activities. Data on the direct environmentalload and the social environmental load can be recorded for every
factory and office, and is centrally managed. The environmental loadsof all facilities are collated and used for Environmental Action Plan goal
management and to gauge progress toward achieving the emission
neutral goal. External complaints, awards received, and communication with stakeholders are kept and shared within the Group to promote
effective environmental action.
In fiscal 2008, we added automatic connectivity between the system and JWNET†1 through EDI†2 for creating and sending electronic
manifests for waste disposal. This allows data to be centralized in theenvironmental load evaluation system’s database, including contracts
with industrial waste collection and transportation companies or waste
disposal companies, and governmental authorizations.
Because e-manifests †3 are difficult to counterfeit, their merits
include accurate monitoring of appropriate waste disposal and prompt
responses to cases of inappropriate disposal, as well as enabling
ef ficient information management by waste emitters, industrial
waste collection and transportation companies, and waste disposal
companies.

Until recently, each business site and affiliated company of the Hitachi Maxell Group
had its own environmental policies basedon a certified ISO 14001 environmental
management system.
In fiscal 2007, however, they began
developing an integrated EMS covering allseven areas within Japan to strengthen corporate governance, to make environmental
action more effective, and to coordinate
with the EMS under the Hitachi Group’s

This process involved integratingeach business’s EMS-certified committee,
ensuring compatibility with the goals andtargets of the Hitachi Group Environmental Action Plan and EMS, as well as devising an integrated environmental evaluation
system that takes account of the disparate
methods used in each area. Certification
was received in December 2008.

Environmental Management System (EMS)
Within the Hitachi Group, we determine the minimum level ofenvironmental management for each plant or factory according to its environmental load, determined by a multiple-criteria
evaluation system. Any location where the environmentalload exceeds a certain level is required to develop an environmental management system (EMS) based on ISO 14001
standards and then must be certified by an accredited outside
agency. As of March 2009, individual certification had been

Directive on Ecodesign of Energy-using Products†2 Energy efficiency standard achievement rate
This value indicates the rate of achievement of the energy efficiency targets set for applicable
home appliances based on the Act on the Rational Use of Energy (also known as the energy savinglaw). The target values are defined by the most energy efficient products available at the time.

How DfE Assessment Is Performed
At the product design stage, the environmental burden is assessed quantitatively ateach product life cycle stage using DfE assessment criteria. If a product scores atleast equal to or more than level 2 (the reference level before the latest major modelchange) in all eight criteria and its average over all the criteria is level 3 or more, it isdesignated an Eco-Product.

Example of Improving Efficiency of Global Warming Prevention
Employing a low-speed high-efficiency motor and IQ-PAM*1 engine,
this air conditioner has seasonal power consumption*2 of 1,336 kWh.
To make it easy to replace, the room unit is just 798 mm wide, offering compactness and energy saving performance. Size and energy
efficiency are further enhanced by an environmentally conscious
control system based on a sensor that monitors the locations andmovements of people. As a result, global warming prevention efficiency is improved from 0.03 for the reference product to 0.06, for a
global warming prevention factor of 1.9.

Example of Improving Resource Efficiency
The Ultra Thin LCD TV has been produced with a thickness of just 35
mm*1 by applying advanced technologies, including confined-space
fan-less ventilation that cuts internal heat and a thin LCD modulewith both high image quality and a thin profile (from using a newly
developed diffuser). Moreover, a Hitachi-original rigid frame design
strengthens the slimmed-down frame, and the power unit is 1/3 thethickness of conventional units.*2 As a result, resource efficiency isimproved from 502 for the reference product to 1,439, for a resource
factor of 2.9.

*1 The IQ-PAM engine, unique to Hitachi, is a controller circuit that gathers information from internaland external sensors for optimizing an air conditioner’s performance and energy saving.
*2 Seasonal power consumption is calculated based on conditions deﬁned by the Japan Refrigeration
and Air Conditioning Industry Association (JRA 4046). The Tokyo model for outside temperature
conditions is used in the calculations.

Increase in Resource Recycling from Used Products

Since fiscal 2001, the Hitachi Group has
established and operated home appliancerecycling companies in three locations inJapan—to take the initiative in working tocreate a material-cycle society. In fiscal
2008, we set up a framework for effective
recycling of resources across the entire
life cycle of Hitachi Group products, frommaterial procurement to manufacture andcollection. As an example, we are working
to separate components from hard drives,
motors and other products that contain rare
metals, so that these scarce and valuable
resources can be recycled. We also developed equipment that disassembles usedcompressors and retrieves the motors,
making it possible to recover rare metals
from the motors.

CO2 emissions from transportation increased 12 percent from theprevious year due to an increase in shipments of basic materials,
predominantly metals. However, energy used in transportation perreal unit output was cut by 1 percent due to a modal shift that boosted the volume of rail and marine shipping in the Group by more than

Fiscal 2008 Outcome | Reducing Water Use

By promoting water conservation, the Hitachi Group kept total water
use in fiscal 2008 to 71.48 million m 3, 3 percent below the 2005
level. At electric appliance production plants in China and the restof Asia, we effectively used water by reusing cooling water frommanufacturing as coolant in other processes, and then we used it athird time for quality inspection. Due to these efforts, we were able
to limit total water use in plants outside of Japan to 12.22 million m3,

Introducing Super Eco-Factories
Takasago Works, Hitachi Cable, Ltd.
Hitachi Cable’s Takasago Works in Hitachi City, Ibaraki Prefecture, Japan
makes gallium arsenide (GaAs) and gallium nitride (GaN) single-crystal
semiconductor wafers. In the plant, there are many clean rooms, andbecause air conditioners for clean rooms use three to four times moreenergy than ordinary air conditioners, reducing their environmental load
has long been a challenge. Using inexpensive PLCs (programmable logic
controllers), Takasago Works engineers developed their own control systemthat responds to load changes. They have been promoting energy saving
in clean room air conditioning since 2007.
The central air conditioning system at the Takasago Works uses a heatstorage tank. Cold water from the cooler part of the tank is used in the
air conditioner. After the cold water is warmed by the air in the room, it
is returned to the warmer part of the storage tank. Generally, a variable
speed pump is controlled to keep the pressure of the cold water constant.
However, in spring and fall, when the air conditioning load is light, cold water
is returned to the storage tank before it can warm up, causing chiller inefficiencies. To prevent this from happening, the engineers developed a cold
water control system that handles load fluctuations and boosts efficiencies.
This system*1 controls the variable speed pump to keep the temperature of
the returning water around 15˚C. The result has been an 810-tonne, or 30
percent, reduction in annual CO2 emissions over previous levels.

handles the post-processing of power semiconductors and manufactures
airtight terminals from ceramics.
The pure water used for dicing and cutting in the process of manufacturing high-voltage diodes has conventionally been wasted, but now it isbeing processed with activated carbon and reused. At the same time, waste
heat is used to heat industrial-use water that in turn makes pure water. Thissystem saves the energy equivalent of 76
kiloliters of heavy oil. Moreover, since 2005,
final waste has been reduced to less than 0.1
percent. The plant has achieved zero emissions for the seventh consecutive year. In
fiscal 2007, Ibaraki Prefecture acknowledged
the company, calling it “earth friendly.”View of the factory

Hitachi Computer Products (Europe) S.A.S.
Hitachi Computer Products (Europe) S.A.S. is a manufacturing base on
the outskirts of Orléans, France, that makes data storage products. Morethan 80 percent of the company’s large (500,000 m2) and verdant site iscovered with trees.
Over the last three years, the company has been using a management model developed by the EFQM (European Foundation for Quality
Management) on product quality, the environment and safety, to successfully reduce energy consumption, waste, VOC emissions, and water use.
At the site, where VOC emissions have been cut to one-seventh of theirprevious levels, the fiscal 2010 environmental goals have already been met.
This achievement shows the united commitment of employees in protecting
their rich natural environment through, for example, environment patrols.
The company is also an active participant in the geothermal power
generation project launched by the local economic association of Orléans
and its environs. The goal is to use subterranean heat from a depth of 1,000
meters to create energy. The company intends to use this geothermalenergy to reduce CO2 emissions by 30 percent.

I applaud Hitachi’s strategic targeting of the environment, reflected in their environmental sustainability andCSR reports, and the commitment expressed in the
Chief Environmental Strategy Officer’s message. However, what is needed now, I feel, is an Environmental

makes a solid social contribution to biological diversity,
but I would also like to be able to see what steps arebeing taken by the businesses of the Hitachi Group.
