Segment Environmental
Accounting
Corporate environmental accounting targets
corporate environmental activities as a
whole but can be used in decision making
only in limited cases. However, segment
environmental accounting, in which corporate
environmental activities are conducted by
project, can be used in decision making
in many cases. Segment environmental accounting
is especially useful in predicting the effects
of environmental activities. The Ricoh Group
announced its adoption of segment environmental
accounting in 1999 and put it into practice
by taking various measures. In fiscal 2001,
the Group continues its efforts to promote
sustainable management by conducting segment
environmental accounting at various opportunities. |

Environmental Action Plan (fiscal 2002-2004) |
Estimated Costs and Effects of Reduction
in CO2 Emissions at
Business Sites |
Estimated
effects of the greenhouse gas
emission reduction plan at business
sites
Total CO2 emissions
generated at production sites
and non-production sites will
be reduced by 13%, and those
in terms of the CO2
emissions per sales unit, by
62%, by fiscal 2010 (Ricoh only,
compared with fiscal 1990).
Accordingly, the Ricoh Group
is planning to reduce its CO2
emissions per sales unit in
fiscal 2004 by 20% from that
of fiscal 2000. Specific measures
include improving processes;
introducing highly efficient
facilities including cogeneration
systems, and using new types
of energy. Effects of 105 energy-saving
investment projects are estimated
by segment environmental accounting. |

Costs are estimated
from past development costs. Effects are
estimated from the number of products scheduled
to be marketed between fiscal 2002 and fiscal
2004. Figures for reduction in heat and
light expenses and CO2
emissions are
estimated from the amount reduced over three
years, from fiscal 2002 to fiscal 2004,
on the assumption that the machine is used
eight hours a day, twenty days a month. |

Estimated Costs Efficiency of an Ice
Thermal Storage/Chilled Water System
in Environmental Conservation |
| To update
the air-conditioning systems
at its manufacturing plants,
Ricoh Microelectronics Co.,
Ltd., one of the Group companies,
conducted segment environmental
accounting to compare an ice
thermal storage/chilled water
system with an absorption-type
chilled/hot water generation
system and determined which
is better for environmental
conservation and cost reduction.
From its results, Ricoh Microelectronics
decided to introduce the ice
thermal storage/chilled water
system because, although the
initial cost of the system was
¥34.45 million more than
that of the absorption-type
system, it would reduce running
costs by 30% and CO2
emissions by 60%. |

Estimated Costs and Effects of Semiconductor
plant at the Yashiro Plant in Environmental
Conservation |
| In fiscal
2001, the Yashiro Plant, a Ricoh
production site, introduced
a system that recycles the hydrofluoric
acid used in the semiconductor
etching process, as well as
an inverter control system.
The segment environmental accounting
shown below reveals that this
system significantly contributed
to environmental conservation
and cost reduction. |

Environmental Conservation Costs and
Effects of a Cleaning Process in Ricoh
Industrie France |
| In fiscal
2000, Ricoh Industrie France
S.A. switched from water to
air pressure to clean its thermal
paper production line. Along
with water recycling by steam
collection, the switch reduced
the company's annual water consumption
by 43.4%, down from 25,353 m3
per year. Ricoh Industrie France
saved on the cost of wastewater
disposal using this system. |

Environmental Conservation Costs and
Effects in Developing QSU Products
|
| In fiscal
2001, Ricoh reduced CO2
emissions of the products marketed
by the Ricoh Group worldwide
by approximately 16,000 tons
through incorporating QSU technology
into its digital multifunctional
copiers, the Aficio 1035/1045
and 1022/1027 series (imagio
Neo 350/450 and 220/270 series,
respectively). The reduction
is equal to ¥1,040 million
in electricity bills. It was
discovered in segment environmental
accounting that Ricoh's development
of energy-saving products roughly
corresponds to a cost reduction
of ¥1,048 million. |

| Environmental
Conservation Costs and Effects in
the Recycling Business in 2001* |
| Efforts made
in Japan include improving the
collection, recovery, and recycling
efficiency by making use of
a recycling information-sharing
system and nationwide recycling
system. Increased profitability
will be achieved by significantly
reducing the cost of collection
and disposal through an advanced
venous logistics system and
increasing the sales of recovered
machines. For regions other
than Japan, it was decided that
used products will be collected,
recovered, and sold within the
same region. Efforts are being
focused on improving collection
rates and the expansion of recycling
sites. The Group's recycling
activities are thus evolving
into a recycling business. |

| New
Framework for Internal Environmental Accounting |
|
|
|
| In the past, environmental
accounting systems were used as tools to
evaluate and disclose environmental impact
reduction effects and environmental conservation
costs. For the purpose of supporting decision-making
processes in environmental management, however,
we need something more. The Ricoh Group
measures and evaluates the environmental
impact generated in all relevant processes
(environmental impact potential) as one
of the approaches for a new environmental
accounting taking the eco-balance into consideration. |
