Plant Data
All of Us at Toyota Are
Challenging Environmental Issues Together
As part of its policy of information disclosure, Toyota has been publishing its Environmental Report since 1998
to better understanding of its approach to environmental issues. These reports have included environmental
data from each of Toyota’s plants. To inform everyone of the characteristic actions being taken by each plant,
we have started a separate booklet called “Toyota Motor Corporation Plant Data.” We have tried to make the
data contained in this booklet easy to understand, by including the specific actions being taken at each plant,
such as the pursuit of production activities that aim to generate no waste and the reduction of substances of
environmental concern, along with their results.
As for the environmental management system (EMS) at each plant, updates or continuous audits by external
auditing organizations have confirmed that appropriate maintenance and continuous improvement have been
taking place: the plants have passed these audits without any problems. Internal audits as well as self-audits by
plants and housing works are conducted in order to ensure continuous improvement. For Toyota’s
comprehensive approach to environmental issues, please also refer to the Toyota Environmental Report 2002.

Activities in FY2001
As part of our “Green Actions,” the Honsha Plant has been carrying out environmental preservation activities as a member of the local community, such as
cleaning the streets surrounding the plant, which are used by the people living in the community, and cleaning the agricultural waterways adjacent to the plant.
Other actions being taken to prevent violations and complaints include the introduction of low-noise pressing machines that use motion-link mechanisms, the
reduction of sulfur oxides through changes in the fuel in the heat-treatment process, and regular monitoring of environmental measurements. To improve
communication with the surrounding communities, the Honsha Plant has been taking actions that promote information disclosure and increase understanding,
for example, inviting the heads of the 24 municipalities surrounding the plant for a plant tour and disclosure of information on PRTR substances.

Activities in FY2001
One item of focus was to hold meetings of the Environmental Preservation Committee chaired by the Plant General Manager once every 3 months in order to
promote environmental preservation activities on a timely basis, with participation from everyone from the management to worker levels. In terms of actual
results, the Kamigo Plant greatly exceeded the company’s fiscal year goal for reduction of CO2 and waste. Also, under the banner of “Perfect Sorting,” great
improvement was made toward completely eliminating sorting errors at resource stations through training and increased employee awareness. The Kamigo
Plant is making efforts to maintain good communication with the community by reporting the status of these activities, along with such environmental
parameters as air and water quality levels, to the Environmental Preservation Liaison Committee consisting of representatives from the five townships
surrounding the plant.

Activities in FY2001
All employees at the Takaoka Plant have been working to reduce substances of environmental concern based on the just-in-time principle of not making
anything that is not absolutely necessary. For example, in the pressing process, wastage of resources has been reduced by decreasing the volume of rejects
to a level approaching zero, through a detailed study of the best processing conditions at the prototyping stage. During the switchover of the Corolla, a
thorough review of the packaging form of parts at the production preparation stage was done thus eliminating the generation of waste at the source. As for
communication with local communities, the Takaoka Plant holds regular community meetings to introduce its activities and disclose environmental data.
These meetings, together with activities such as cleaning of the areas surrounding the plant by employees, have helped people in the surrounding
communities gain an understanding of the plant’s environmental actions. As part of efforts to maintain an open plant, facilities are actively made open to the
public; in FY2001, approximately 4,500 people toured the wastewater treatment plant.

Activities in FY2001
The Miyoshi Plant is located adjacent to a residential district, so it pays close and detailed attention to the effect it has on the local area. For example, the
plant conducted regular patrols at site property lines for early detection of sensory pollution such as noise and offensive odors. In order to gain the
understanding of local residents, each year the plant invites the heads of each ward for a plant tour, and discloses information to community councils. In an
effort to keep the local environment beautiful, the Miyoshi Plant also participates in beautification activities carried out in the neighborhood, as well as in the
cleaning of the Miyoshi Pond organized by Miyoshi-cho.

Activities in FY2001
In October 1999, the Tsutsumi Plant became the first Toyota plant to achieve “zero landfill waste.” To further reduce the volume of waste, the goal of achieving
“zero combustible waste” in 3 years starting from April 2001 was established. All employees at the plant have been working together toward this goal, and
were able to reduce the volume of incineration waste by about one half in FY2001. At the biannual local community councils, people from the local
communities are allowed to confirm these actions as well as other activities being carried out by the plant, and their requests and concerns are quickly
addressed.

Activities in FY2001
Starting from the design stage, the Shimoyama Plant strictly complied with legal requirements, for example, using a sealed building to keep nighttime noise at
the plant boundary to 50 decibels or lower. It has also taken measures toward preservation of the local environment and presently operates in a beautiful
environment, always surrounded by seasonal flowers and greenery.
The Shimoyama Plant also considers communication with people in the local communities important and has been holding annual “Community Councils” on
the environment, to increase understanding of our environmental actions. Global environmental measures are being implemented on a continual basis.
Despite the fact that the operation start of a new line for the AZ-type engine increased the production level at the plant, total CO2 emissions were maintained
at the previous year’s level through proactive measures by employees such as “taking measures associated with energy-saving facilities,” “turning off power
during holidays and at night” and “powering off machines between shifts.” Furthermore, we reduced the volume of waste by as much as 33% by promoting
recycling and the introduction of a condensing system for coolant waste liquid.

Activities in FY2001
In addition to the energy conservation and waste reduction measures already in place, the Tahara Plant has since FY2000 been promoting environmental
preservation activities by incorporating into its environmental goals the reduction of industrial water consumption because of its local importance. The plant
also holds information-exchange meetings with the mayors and representatives from the surrounding communities twice a year (in the spring and autumn)
and incorporates their opinions into the plant’s environmental preservation activities. During the Global Environment Month in June, the Tahara Plant
participated in the Group for Beautifying Tahara and carried out beautification activities in the region. In FY2002 also, environmental preservation activities will
be promoted every day to ensure that no problems are caused for the people in the surrounding communities.

Since the acquisition of ISO 140001 certification, which covered all processes from design to production, in December 1998, the Teiho Plant has been
promoting three major objectives - complete elimination of legal violations and complaints, reduction of waste, and reduction of CO2 emissions - under the
motto of “Full Participation by Every Employee.” Some specific efforts to emphasize cooperation and harmony with the local communities include, cleaning
the Aizuma Megawa River, into which the plant discharges its wastewater, beautifying the areas surrounding the plant, conducting environmental patrols,
holding community council meetings with local government representatives and mayors, and opening the plant’s health and recreational facilities to the public.
In 2000, the goal of “zero landfill waste” was achieved. Beginning in 2001, the Teiho Plant has been working on expanding recycling by enhancing resource
sorting stations and ensuring more thorough sorting toward achieving the goal of “zero combustible waste.” In order to achieve “a green and quiet plant that
coexists with the environment,” the plant will continue to promote green activities.

■ Reduction of food waste and introduction of a garbage processing machine
Beginning in February 2002, the volume of garbage generated from the cafeteria was reduced from 40kg/day to about 1/10 that volume, using a
bio-reduction kitchen garbage processing machine.
■ Communication with the people in local communities
(1) Cooperation with the Kasugai City Office
Since the plant is located inside the Kamiya Industrial Park and is not surrounded by residential housing, it tries to maintain communication with the
Kasugai City Office.
In FY2001, two meetings were held (in May and November), that included on-site tours and exchange of opinion on environmental actions with a view
to improving them, and also increasing mutual understanding.
(2) Events during the Global Environment Month
As part of the annual events during the Global Environment Month in June, efforts are made to beautify the environment by picking up trash from the
area surrounding the plant.

Environmental Center
Facility Overview
■ The Toyota Environment Center is an energy recovery plant that is adjacent to the Motomachi
Plant. The Center generates electricity and steam by burning combustible waste and functions
as the energy source for the Motomachi Plant.
■ In order to efficiently generate energy from waste, the Center uses a fluidized bed boiler and a
co-generation system, saving approximately 25,000 tons of fossil fuel each year.
■ The Center uses super heaters that create high-temperature steam to generate the maximum
amount of electricity, and also utilizes low-pressure steam following electricity recovery, thus
achieving a maximum thermal efficiency of 85%.
