| Results of the Prior Assessment System for Environmental Preservation |
When
introducing new raw materials or supplementary materials, and
when installing new facilities or expanding existing ones, Toyota
assesses the environmental impact in terms of air and water
quality, offensive odors, vibration, noise, waste and chemical
substances, based on its Prior Assessment System for Environmental
Preservation. The assessment results are then incorporated into
the plans, thus ensuring thorough implementation of preventive
measures.
In FY2002, the number of items on which prior assessments were
conducted decreased compared to FY2001, however, the number
of assessments done on new raw materials associated with the
development of fuel cell hybrid vehicles and substitutes for
substances subject to PRTR increased.

is counted as one assessment |

| Inspections by Environmental Managers (Plant General Managers) |
In
conjunction with the Global Environment Month held within the
company every June, Toyota had its plant general managers conduct
inspections of the status of implementation of environmental
preservation activities at all plants and housing works. In
FY2002, the inspections focused on activities aimed at zero
legal non-compliance, environmental accidents and complaints,
and ascertained the implementation status concerning such things
as measures to prevent the recurrence of previous accidents
and the thorough implementation of environmental management
by contracted companies working on Toyota premises.

| Reporting and Storing Devices with PCB |
| In FY2002, Toyota reported to the
government on its storage of 5,247 transformers and condensers that
contain PCB (polychlorinated biphenyl). The reason for the increase
in number compared to FY2001 is that devices with low PCB content
were additionally made subject to regulation. Toyota is safely storing
these devices in accordance with the standards specified by law to
prevent leakage and soil contamination. |

| Soil and Groundwater-Related Measures |
In
FY2001, Toyota completed the soil remediation measures that
it had been carrying out at all six plants — the Honsha, Motomachi,
Kamigo, Takaoka, Miyoshi and Tsutsumi plants. Measurements taken
indicated that the levels of trichloroethylene, 1,1,1-trichloroethane,
and dichloromethane were all below environmental standards.
In terms of groundwater contamination prevention, Toyota completed
an effluent-prevention measure in 1997 which involved the digging
of barrier-type wells and pumping and remediating groundwater.
Toyota has continued groundwater remediation using pump and
treat technology, and regularly monitors measurements. Toyota
reported these measurement results along with the remediation
status to the government, as well as to local councils in the
surrounding communities.

•Trichloroethylene Measurement Values in FY2002
*Measurements are taken at all
plants and housing business sites
*Has not been detected in plants other than those listed (At
the three housing business sites, measurements began in 1997)
*The level has a range since each plant includes multiple measurement
points |

| Promotion of Measures to Prevent Soil and Groundwater Contamination by Oil Leakage |
In
order to avoid Environmental Riskks from soil contamination,
in 1997 Toyota began taking measures to prevent oil leakage
from underground tanks by relocating pipes above ground, using
dual-walled tanks, etc., and completed these measures in 2000.
In FY2001, Toyota began implementing measures designed to prevent
leakage from machinery and equipment, and in FY2002, extended
these measures to underground pits for stamping machines and
coolant tanks for machinery.
Counter-measures to prevent soil contamination from any piece
of equipment that may leak oil are due to be completed in FY2005.

| Communication with Surrounding Communities |
In
FY2002 as well, Toyota held community council meetings to disclose
information regarding its environmental initiatives and engaged
in dialogs with people in the communities surrounding all of
its plants and housing works. At these community council meetings,
Toyota explained its framework for managing chemical substances,
disclosed substance release data, reported on environmental
conditions around the plants, and exchanged opinions.
Members of the local community expressed various opinions and
requests, including: "I would like a simpler explanation regarding
chemical substances" and "I want my kids to learn about the
environment, so I would like them to be able to tour the plant."
