Green Procurement Guidelines ～Toward the Realization of a Sustainable Society～
Hitachi GroupOctober 2005
Introduction
At the dawn of the 21st century, it is required to transform the present “one-way society” of production,
consumption and disposal, into a “sustainable society” in which the entire life cycle of products are
considered.
Placing the global environment as the very crucial issue for all mankind, the Hitachi Group is
attempting to harmonize with the environment as one of the most priority issues, and aiming at
achieving environmental conservation and economic growth based on three pillars such as
environment-friendly manufacturing, environment-friendly production activities and the establishment
of environmental conservation system for the better society.
It is essential to recognize the importance of purchasing function while necessary measures shall be
taken against environmental problems in corporate management. In other words, appropriate
measures shall be taken at the stage of purchasing materials and parts in order to reduce environmental
loads through the provision of products and services. These materials and parts largely affect the
reduction of environmental loads at the stage of their use including energy saving, proper disposal,
recycling and other measures after use. Furthermore, they are closely linked with the control of
chemical substances and measures against pollution.
Particularly regarding chemical substances, the Restriction of Hazardous Substances in Electrical and
Electronic Equipment Directive (RoHS Directive (20002/95/EC)) came into effect in member nations
of the European Union in February 2003, and in line with this, laws and regulations for chemical
substances included in products are going to be more stringent in various regions such as Japan, Europe
and China from July 1, 2006.
Under the circumstances, the Hitachi Group, in response to the global trends in environmental measures,
reviewed MONOZUKURI (designing, manufacturing or repairing of products) throughout the Group
from the perspective of CSR, and established “Environment and CSR-Based MONOZUKURI
Standards” in 2004. This aims to reduce environmental loads by products throughout their entire life
cycle, including management policy, product planning and design, procurement and manufacturing,
distribution, product use, recycling, and disposal.
In order to procure goods with less environmental loads, or to implement green procurement in other
words, the Hitachi Group has revised herein its “Green Procurement Guidelines”.
In the supply chain we will endeavor to build trade relationship by clarifying the range of responsibility
based on trust, and therefore our suppliers’ understanding and cooperation are really appreciated.

Hitachi Action Guidelines for Environmental Conservation
Purpose In order to realize an environmentally harmonious and sustainable society through products and services, Hitachi is committed to meeting its social responsibilities by promoting globally-applicable “MONOZUKURI” (designing, manufacturing or repairing of products), which is aimed at reducing environmental burdens of products throughout their entire life cycles, ensuring environmental conservation. Action Guidelines 1. Global environmental conservation is a critical challenge shared by all humans. Hitachi is
committed, therefore, to fulfilling its responsibilities by assisting in the realization of an environmentally harmonious and sustainable society as one of its management priorities.
2. Hitachi will make efforts to contribute to society by developing highly reliable technologies and production processes, while identifying needs considering concerns related to global environmental conservation and limited resources.
3. Members of the board in charge of environmental conservation are responsible for facilitating appropriate environmental conservation activities. Departments responsible for environmental conservation should endeavor to promote and ensure environmental conservation activities, including improving environment-related rules and regulations and setting goals for environmental burden reduction. These departments should also confirm that their environmental conservation activities are conducted in a proper manner and ensure that these activities are maintained and improved.
4. Hitachi will promote globally applicable “MONOZUKURI” with the aim of reducing environmental burdens at every stage, including product research and development, design, production, distribution, sales, usage and final disposal.
5. Hitachi will investigate and review the environmental impact caused in the course of its “MONOZUKURI” processes. Hitachi will also introduce excellent technologies and materials useful to safeguard the environment, in other words, to reduce environmental burdens through energy and resource saving, chemical substance management, recycling, and other measures.
6. Hitachi’s environmental conservation efforts are not only to be focused on observing international environmental regulations and those of national and local governments, but also on conserving the environment by implementing voluntary environmental standards when necessary.
7. Regarding globally-applicable MONOZUKURI activities, impact on the local environment and community are to be considered. In addition, measures that meet local communities’ requests should be implemented.
8. Hitachi will educate its employees on the observance of environment-related laws, raise their environmental awareness and encourage their interest in society at large and broad-based environmental conservation activities.
9. Hitachi will evaluate potential environmental problems and prevent them from occurring. In the event that any environmental problem occurs, Hitachi will take appropriate measures to minimize the impact on the environment.
10. Hitachi will make efforts to disclose information on its environmental conservation activities to its relevant stakeholders. Hitachi will also actively communicate with these stakeholders so as to strengthen mutual understanding and forge cooperative relationships with them.

Composites Judgment criteria
Chemical compounds, polymer alloys, metallic alloys, etc. Considered as homogeneous materials
Raw materials such as paint, adhesives, ink, paste, plastic polymers, glass powder, and ceramic powder
The substance formed in the final process stage of the respective assumed uses is considered as a homogeneous material. Ex.: Dried and cured state in the case of paint and adhesives : State after molded in the case of plastic polymers : State of glass and ceramics after they are formed
Monolayers formed by painting, printing, plating, etc.
Individual monolayers are considered as a homogeneous material. (In the case of zinc plating chromate treatment, the zinc plating layer and the chromate treatment layer are individually considered as a homogeneous material.) State of individual monolayers in the case of multilayers: However, if it is difficult to obtain the values for monolayers by separating multilayers, the minimum separable unit is considered as a homogeneous material unit.
■ Definition of the denominator and the numerator for calculating the content percentage of
the mass of included chemical substances
（１）Definition of the denominator
Prohibited substances: for each homogeneous material
Controlled substances: for each delivered product or each hierarchy obtained by dividing
the delivered product into arbitrary hierarchies
[Definition of homogeneous material]
・ Homogeneous material means the one composed of single chemical compounds or
molecules.
・ For composites, follow the table below.
（２）Definition of a numerator
・ Chemical substances mean "chemical elements or compounds".
Chemical substances Definition of a numerator
Metals and metallic compounds etc. Mass of metallic elements
