Message from the President
As we start the 21st Century, we find ourselves increasingly moving towards becoming a loop-based society that recycles and reuses resources and can undergo sustainable development in a way that ensuresboth environmental preservation and economic growth. In corporate management as well, the environment has become a key consideration in business strategy.
In accordance with our corporate motto, "Inspire the Next," the business activities of the Hitachi Groupaim at making a society capable of sustainable development based on a policy of recycling and reusing
resources from the broad perspectives of the environment, safety, and economic efficiency, with the aim ofmaking us the most trustworthy business partner in the world, indeed, the "best solution partner."
In fiscal 2000, the Hitachi Group strengthened consolidated management and carried out an environmental burden study for subsidiaries and affiliates, expanding the scope of report to about 300 such companies in the group. In March 2001, we also revised our Green Procurement Guidelines to reinforce the
Hitachi Group's green procurement. The data provided has been utilized to link design support and material procurement systems and offer products and services with a minimal environmental burden.

GREEN 21, our program to quantitatively assess environmental activities and improve environmental
corporate management, has reached the last year of its first stage, and is now being expanded. Together
with this, we will continue to carry out environmental action plans in our management, products and services and production activities.
This Environmental Report includes a supplement containing data collected on environmental performance in fiscal 2000, based on the results of our activities. We have also added feedback we received
from NGOs on our Environmental Report 2000. In the same way, we hope to reflect NGOs and other
opinions in Environment Report 2002, to be issued next year, and will further strive to enhance reportingon Hitachi's environmental work.
It is our sincere wish that this report will lead to a deeper understanding of the Hitachi Group's policies
and activities concerning environmental preservation. We respectfully ask for your continued support
and guidance as we face the challenges ahead.

Etsuhiko Shoyama
President and Director

1Environmental Management System
Fundamental Principles of Environmental Activities
Hitachi, Ltd. has embraced environmental activities since 1970. In 1972, Hitachi
began making Companywide environment-related capital expenditures, andthe progress has continued. Further,since 1973, environmental audits fromthe management’s perspective have been
included in performance evaluations.
The Environmental Protection Action
Guidelines were formulated in 1993 andhave served as the basis for the Company’senvironmental activities.
On April 1, 1999, the Hitachi Group
adopted a consolidated business structure that includes the business groupsof Hitachi, Ltd. and 35 major affiliatedcompanies.
In line with these management reforms,
Hitachi also sought to strengthen its
organizational structure to improve theCompany’s stance as regards environmental management Groupwide. One
aspect of this was the establishment of

GREEN 21 Activities

Action Plan
• Improve Green Points for Fiscal
2001 by 21% over Fiscal 1998

In fiscal 1998, the Hitachi Groupestablished GREEN 21, a new system
to evaluate the Group’s environmental
performance. The self-evaluation systemscores all activities against a fixed setof standards and promotes continuous
improvement and a greater level of environmental activities. The system is also
useful for improving the environmental
management of business groups andmajor affiliated companies as well as promotes a greater degree of harmony withthe environment.
The system evaluates 43 environmental performance indicators in eight key
categories: management policies, compliance with environmental regulations,environmental accounting, the consideration for environmental issues in products and services, as well as information
disclosure and education are management performance indicators. Energy
saving at plants, recycling and the management of chemical substances areoperational performance indicators. The
total number of points—called Green
Points (GPs)—for each category is 100,and the entire evaluation has a maximum
score of 800 GPs. The scores are represented on a radar chart, allowing eachbusiness group or affiliated company toeasily use the results in decision making
regarding environmental management.
The evaluation is made annually, allowing
a quantitative assessment of the state ofcontinuing progress in implementation.
Each unit evaluates its own performance indicators with regard to eachcategory once a year and compares thescore with levels from the base year, fiscal 1998, to measure improvement. In
our pursuit of continuing improvement,
our goal for fiscal 2001 is to beat the
total score of the base year by 21%.

N Overview of Hitachi’s Environmental Audits
Action Plan
• Acquiring ISO 14001 certification chiefly for nonmanufacturing sites and enhancing
environmental audits• Promoting green procurement• Strengthening environmental
education and training

Acquiring ISO 14001 Certificationand Environmental Audits
Seeking continuing improvement inenvironmental management and the
reduction of environmental risk, theHitachi Group has introduced an environmental management system based on
the ISO 14001 international standards,
and a number of facilities, principally
manufacturing centers, have been certified as ISO 14001 compliant. (See pages
1 and 2 of accompanying documents
regarding ISO 14001 certified sites.) In
the future, we will seek to continue toimprove through the promotion of anenhanced environmental management
system and pursue ISO 14001 certification for nonmanufacturing business centers, such as software and service firms.
Furthermore, to meet ISO 14001 standards, Hitachi, Ltd. introduced its own
Environment Round Audit System in
1995. The system employs a systemof round internal audits whereby audits
are performed by certified employees
assigned to units other than the unit
being audited to assure the objectivity
and fairness of the audit.
Groupwide seminars are held toimprove the quality of audits, and qualified staff are then registered as internal
auditors. As of March 2000, approximately 1,600 Hitachi Group employees
certified as auditors conducted audits atbusiness sites throughout the Group.

To ensure the preservation of the environment, each Hitachi Group site has
established internal standards more
stringent than most laws and external
regulations. Each site works to prevent
environmental harm through regularmeasurements and the maintenance andsupervision of environmental preservation facilities and equipment. Moreover,
specific training programs are in place toensure that each site has the required
number of employees with environmentrelated legal qualifications.

N Special Qualifications/Legally Certified Staff
As of February 2000, Hitachi’s business activities required a total of 4,833 employees withspecial certifications or qualifications. The Company exceeded these requirements, having
29,279 employees with special certifications or
qualifications as of the same date.

Green Procurement
The Hitachi Group promotes green
procurement policies for administrative
materials to be used by management andnonproduction departments (office supplies, business cards, toilet paper andother supplies). Specifically, the Hitachi

Environmental Education
and Training
The understanding of every employee
is important in our response to environmental issues. Based on its employee
education system, the Hitachi Groupholds Groupwide classes to further
develop its employees’ understanding.

Environmental Accounting
Introduction of an Environmental
Accounting System
Hitachi, Ltd. introduced an environmental accounting system to promote
efficiency and continuous improvement
in environmental investment andenvironmental activities.
Data was compiled for Hitachi, Ltd. on
an unconsolidated basis for the first fiscal
year of operations under the new system.*1
In addition to plant and equipment investment related to environmental activities
announced since fiscal 1997, costs encompassed ordinary expenditure items, such as
R&D expenditures and the cost of operating and managing environmental conservation plants.*2 Effectiveness was establishedbased on an economic result, addressed interms of monetary value, and a quantitative
effect, addressed in terms of the degreeof environmental load abatement. The economic effect was based on reliable grounds.
The quantitative effect*3 was calculated not
only on the basis of the degree of environmental load abatement during the manufacture of a product but also during theuse of the product. Eco-efficiency was also
assessed, in terms of the decrease in cost
per environmental load item.
*1 Environmental load data includes data from some affiliatedcompanies managed on an integrated basis in business
operations of the parent company.

*2 These figures are based on the “Draft Guidelines for
Measuring and Announcing Environment Cost,” Environment Agency of Japan (issued March 1999).
*3 Hitachi used its own system to estimate the abatement effectunder conditions of standard use.

Goals of the Introduction of theEnvironmental Accounting System
The environmental accounting system
was introduced as information for environmental management to promote
efficiency and continuing improvement
in environmental investment andenvironmental activities.
Furthermore, through the disclosureof information regarding the distributionof management resources to environmental activities and regarding environmental technologies and products,
Hitachi, Ltd. seeks a greater understanding of its commitment to being a company in harmony with the environment.
Environmental Accounting
Approach and Concept
Hitachi, Ltd. decided in July 1999 tointroduce the environmental accounting
system. A project team of employees
drawn from the financial and environmental divisions studied environmental
accounting items and methods. Also
during this time, Hitachi took part in a
Study Group on Practical Matters about

Introducing Environmental Accounting
established by the Environment Agency
in June 1999. Hitachi views the system
as a means of improving eco-efficiency
and achieving rational environmental
management.
Results from the First Fiscal YearThe chart below presents an overview
of the results for fiscal 1999. (See page 3of the accompanying documents for amore detailed report.) Of special noteis that Hitachi’s R&D expenditures(¥11.14 billion) accounted for 42% of
the total expenditures and investment
related to environmental activities.
As a result, energy consumed during
the use of products by end users decreased
an estimated 165 million kWh—the equivalent of energy consumed in one year by
48,000 average households.
Future Approach to Environmental
Accounting
In the future, the data used will bedrawn for an increasing number ofHitachi Group companies. Moreover,the data will be made more comprehensive, and more details of the data will
be disclosed.
Hitachi intends to use the implementation of the environmental accounting
system to promote rational economic
management and to contribute to thesociety of which it is a part by balancing
corporate growth with the protection of
the environment.

Product development that seeks to minimize environmental load in all stages ofthe product’s life cycle—including theselection of a product’s component materials, its manufacture, use, recovery, disassembly and disposal (a life cycle
assessment (LCA))—is necessary for theestablishment of a recycle-oriented
society. With this in mind, we are working to create products that reflect thethree Rs—reduce, reuse and recycle—
promoting the reduction of emissions at
the disposal stage, the reuse and recycling of products and their components
and, in particular, energy savings andthe reduction of by-products at the
manufacturing and use stages.

a certain standard on the DfE assessment
are registered as green products, and in
December 1999 a system of disclosure
guidelines was put into effect regarding
environmental information, whereby
information is presented through indicator marks and data sheets.
Selection and Integrationof Plastic Materials
Recycling efforts are under way for suchmetals as iron, copper and aluminum.
To improve the proportion of recyclable
materials, it is necessary to change tomaterials that have less environmental
impact than molded plastic materials.
With regard to the selection of molded
plastic materials, 13 selection categories—including energy consumed during manufacturing, recyclability andlongevity—were prepared in “Guidelines
for the Selection of Eco-Materials” in
1993, and the guidelines are applied
from the design stage. In 1997, Hitachirevised the guidelines to reflect changes
in materials for use in products.
In addition, criteria for integrating
molded plastic materials based on theirproperties—such as flame retardancy,
melt flow rate and flexure/resilience—
were set out in 1999 in “Guidelines for
Integrating Grades of Molded Plastic Materials.” Grade ratings for principal resinscovered in the guidelines—acrylonitrile
butadiene styrene (ABS) resin, polystyrene (PS) resin, and polypropylene(PP) resin—have been reduced by 62%.

Chemical Substance Management
The Pollutant Release and Transfer
Register (PRTR) Law was enacted in July
1999. In response, Hitachi revised its
autonomous management of chemical
substances with regard to their use in
consumer goods (See page 18.). Chlorofluorocarbons (CFCs) used as coolant inrefrigerators and as foaming agents inthermal insulation will be completely
eradicated, and, since the end of 1995,
there has been a change from the use of
CFC (HCFC-141b) as a foaming agent
in thermal insulation to the use of thehydrocarbon cyclopentane. Regarding
lead and lead compounds, also the targetof reduction activities, since 1989 wehave manufactured larger computerswith lead-free solder using tin and silver
substitutes. Moreover, since 1999 wehave manufactured notebook computers,
8mm cameras, washing machines, airconditioners and other products withlead-free solder, using tin, silver andcopper instead. In addition, our PCs
use eco-boards—halogen-free flame
retardant printed wiring boards.

Recyclability Evaluations
The Disassemblability Evaluation
Method (DEM) was developed in 1993
as a quantitative measurement of theease with which a product could be disassembled and recycled after use, andstipulations regarding consumer electronics goods and office automationequipment have been implemented andenhanced. In April 2001, the Law for the
Recycling of Specified Kinds of Consumer
Electric Goods (the Consumer Electronics
Recycling Law) will take effect, requiring
manufacturers to handle recycling efforts
for products they manufacture. We haveestablished and begun using a Recycling
Evaluation Method (REM) based on theprocedures required to recycle a given
product and economic feasibility.

Concerning procurement, Hitachi’s green
procurement policies give priority to suppliers of products, components, materials
and other goods produced in consideration of the environment. In July 1998, we
distributed copies of our Green Procurement Guideline to 3,100 suppliers.
Each business site also conducts environmental load surveys of its suppliers,
waste disposal contractors and otherbusiness contacts, providing information
on environmental activities and conducting educational activities annually.
Hitachi supports the environmental
activities of its suppliers and other business contacts, striving for sustainableproduct development.

management to recycling companies sothat usable resources are utilized to thefullest extent possible. Furthermore, Hitachi
has established guidelines for appropriate
waste disposal and conducts periodic
inspections of its recycling contractors
to ensure that they meet standards set
by the guidelines.
Hitachi aims for zero emissions at
each of its Group sites.
At Hitachi, zero emissions is defined as
an emissions volume of less than 1% of
the final disposal rate of the current fiscal

promulgated in 1996. Moreover, we haveconducted PRTR surveys* since 1998.

Action Plan
• Thorough management ofchemical substances andplanned cuts in emissions
volumes

While chemical substances offer many
improvements to our quality of life, it has
become clear of late that some chemical
substances, such as so-called environmental hormones, have come to have a negative impact on the environment.
In Japan, the Pollution Release andTransfer Register (PRTR) system will
become law in 2002. For corporations,thorough routine management and risk
management with regard to chemical substances has come to be more critical infurthering business.
Prior to the PRTR Law, the HitachiGroup promoted the reduced use of designated chemical substances used in its

initiated in 1999 to raise the level of autonomous management, part of the Company’sefforts to reduce its use of chemicals with
an impact on the environment. The system
includes management guidelines encompassing the procurement, use, disposal andcommercialization of chemical substances
at business sites. The first step is to understand exactly what types of chemical substances are being handled at each businesssite, then to evaluate the substances’ potential impact on the environment and determine how substances should be managed.
“Eliminate,” “Reduce” and “Manage” havebeen set as autonomous management classifications, and, based on these classifications, substitution and elimination plans
are prepared for banned substances, while
specific plans for cuts in use and emissions
are set for substances designated for reduction. Substances in the “Manage” category
are handled in accord with appropriate
handling guidelines and PRTR requirements.

Keeping the Air and Water Clean
Every year, the legal regulations governing the amounts of pollutants in discharges from the workplace into water
systems or the atmosphere grow stricter.
Anticipating this, the Hitachi Group has
instituted its own set of standards regarding discharges that are more exacting
than any official ones. Since the 1996
revision of Japan’s Clean Air Law and the1999 promulgation of the Law Concerning Examination and Regulation of
Manufacture and Handling of Chemical
Substances, it has become more important than ever for companies to act on
their own to reduce the volume of discharges from their workplaces. Currently,
Hitachi is working hard to curb thepolicies toward hydrochlorofluorocarbons(HCFCs), which are due to be phasedout of production use by 2020, pleaserefer to page 9.) Japan’s Clean Air Law
stipulates that companies are responsible
for managing and monitoring their discharge of designated harmful substances
into the atmosphere. Of these substances, trichloroethylene and tetrachloroethylene are particularly noxious,and Hitachi, designating them as prohibited substances, eliminated them fromuse Companywide in May 1995. Hitachi
is also making significant progress in
reducing its consumption of methylene
chloride by making improvements to
production processes and shifting tosubstitute compounds.

workplaces discharge into the atmosphere or bodies of water as well as to recover heavy metals from wastewater before
they reach the general sewage system.

Water Quality Preservation
To curb the discharge of such toxic substances as heavy metals from the workplace into open bodies of water, Hitachi
is pressing ahead with the installation ofwastewater treatment facilities that purify and recycle wastewater after toxic substances have been separated from it andrecovered through the use of filter membranes and other devices. At the Hitachi

Energy Services Companies
While energy services companies(ESCOs) are a new form of business inJapan, they parallel similar business plansthat arose in the United States in the
1970s, centering on guaranteeing energy
savings over the long term throughimprovements in facilities and equipment.
In 1998, as part of plans to promote thisform of business in Japan, the Ministryof International Trade and Industry(MITI) decided to support model ESCOs

established by the private sector.

Comprehensive Water
Environmental BusinessIn recent years, manufacturing and daily
activities in urban areas have caused awater pollution problems in Japan’s rivers
and lakes. The creation of a biotope along
rivers as well as the improvement of thewater quality of lakes and drainage tomaintain flow levels in rivers are required

to preserve the total water environment.
Hitachi is supporting various water environmental management decision making
by enhancing its plant control expertiseand through various simulation technologies, wide area telecommunications
network systems and watershed management systems, utilizing Geographical
Information Systems (GIS).

Hitachi’s Mechanical Engineering Research Laboratory applied
for and received MITI support
for its construction for improved
energy savings, which is expected
to produce annual energy savingsof 15.6% and reduce CO2 emissions by 94 tons. Hitachi isadvancing its ESCO operations
based on the technologies developed in this model business.

The generated heat will be used by new
businesses. In July 1999, the city ofUtashinai, Hitachi Metals, Ltd. andHitachi, Ltd. established a new company
to oversee the venture. The new firm will
begin operations in October 2002.

The Hitachi Group has begun commercial production of next-generation waste
treatment systems that overcome manyof the drawbacks of conventional waste
incineration methods. The Hitachi rotarykiln-type waste thermolysis system maximizes waste energy and reduces the volume of ash by melting it and making it

reusable. Moreover, residual heat is usedwith great efficiency in the generation ofelectricity. High-temperature combustion greatly reduces dioxins, and exhaustgas treatment equipment minimizes thedioxin content of exhaust gas to under
0.01ng-TEQ/m3N. By combining thermal
recycling and materials recycling, thewaste thermolysis and ash melting system makes a significant contribution to
the preservation of the global environment.

Exhaust gases from the etching process,which include PFCs, are washed in theprespray tower to remove such solids as
SiO2. The gases are heated to 750˚C in
the chamber and are decomposed by
the catalyst in the reactor. The hot

decomposed gases are then cooled in acooling room. Since HF gas is formed by
the catalytic reaction, a packed tower is
included to remove the acid from thedecomposed gases. The final exhaust byproducts are CO2 and fluorinated water.

Green 21 Activties●The Increase in the Green Point Average of Hitachi, Ltd.

The improvement in the green point average of fiscal 2000 (from fiscal 1998) was 27.5% for Hitachi, Ltd. alone and 24.7% for Hitachi, Ltd.
and its affiliates (domestic). The consideration for enivironmental issues in products and services, energy saving at plants and environmental
accounting that showed particularly high rises in the average scores were due to the setup of guidelines and their enforcement. The project
was able to be advanced with regard to the 21% rise target for fiscal 2001 (as compared to fiscal 1998). They were front-loaded. During thenext fiscal year, we will consider the targets for the second stage. For the affiliated companies (overseas), we have launched "Green21
Activities" campaign to raise the green point average 21% or more in the fiscal 2003, compared with the figure for the fiscal 2000.
＊ Green point average: The total green points of the site involved divided by the number of sites involved

2001 （Fiscal Year）〈Target〉●Promoting Green Procurement"Green Procurement" Guideline was issued in March, 2001. Last April, we began to collect information regarding the environmental
conservation activities of vendors and business partners, information about chemical substances contained in procured items, and otherenvironmental information via the Internet. The data input screen was prepared in a format on which the customer can easily work and which
is suited for making a database of useful information. Collected information is turned into a database and shared by the personnel within thegroup, and is linked with the design support system and the materials procurement system. It is thus effectively used to develop eco-friendly
products.

Third-Party Comments on the "Environment Report 2000"
Chief Executive
E- SQUARE Inc.

Vice Chairperson of the Organizing Committee
Valdez SocietyPeter David Pedersen

Kimie Tsunoda

Throughout its text, the report makes thereader realize that the entire group is committed
to the management theme of environment activities in a serious
manner, and with goals set. The Environmental Action Plan iscomposed in a relatively easy-to-understand structure and includes
numerical targets and target dates, so that outside parties can easily
assess the details. The Green 21 Activities can be interpreted as aunique attempt, and also as a unique set of "management indicators."
Another thing that I wish to evaluate highly is that the entire report
is condensed into less than 30 pages. However, the report has someproblems too. For example, I may have to define the Hitachi Group's
core values and vision of the environmental issues in a more clear-cut
manner. In-house environmental education and the creation of newvalues are extremely important. I suggest that I should step up theirefforts in these areas more and highlight them in the report. The
company may also want to put more emphasis on linkage with theemployees, their families, customers, clients, NGOs, NPOs,
communities, administration authorities, and other stakeholders both
inside and outside the Hitachi Group and specify it in the report.
Such linkage is indispensable in building up an economy based onrecycling. Since the company has a firm basis, I think that thecompany should find ways to step up its efforts in these areas andcommunicate its ideas to the outside world.

An environmental report is a medium ofaccountability. I am happy to see that, as
compared to the previous one, the current report covers the entire
group and discloses more data in general, resulting in theenhancement of information disclosure in terms of both quality andquantity. However, from the viewpoint of a stakeholder, I think thatthe report entails some problems, including the difficulty to get theentire picture of the environmental burden of the group, theshortage of self-assessment of the environmental burden andimprovements in the environmental burden, the unclearness offigures and diagrams, and the positioning of Data on Environmental
Activities. I also had the impression that the report still failed toshow clearly enough the actual accomplishments in the guidelines
for environmental protection actions of the Hitachi Group, whichstate that "The top priority challenge in management is harmony
with the environment." The issuance of environmental reports has
not yet become a legal requirement. It is also a unique medium
through which corporate culture can be communicated. Firms arealso required to respond to such international trends as theguidelines for reporting sustainability. I hope that the company will
display its international leadership in the field of information
disclosure as a Japanese firm.

We will reflect the precious comments we received on our future efforts inenvironmental preservation and information disclosure through environmental reports
and other means, thus making improvements. More specifically,①We will try hard to make future reports more specific and easier to understand,including not only the status of the results of our efforts in environmental
preservation but also the background behind our implementation of specificmeasures and our basic ideas and the goals which we will pursue in the future.
②Concerning the composition of future reports, we will define more clearly the
relationship between the report proper and the separate booklet of data collection.
We will also compose the materials so that the general pictureand specificdiscussions will be easier to understand and read.

It would be easier to handle if it came as part of the report.
(NPO or equivalent).
●The text in general is in too small font (Customer).
●I wish the report would show future policies and directions
more specifically (Reseach or educational establishment).
