Fiscal 2001 Ricoh Group Corporate Environmental Accounting(24KB)

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.

The Ricoh Group's Segment Environmental Accounting for its 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.

Estimated effects for the energy-saving product marketing plan

The Ricoh Group is making sincere efforts to reduce the amount of power the products consume while in operation or on standby. CO2 reduction and marketing contribution to gross profit are estimated by the number of products to be marketed from fiscal 2002 to 2004.

Segment Environmental Accounting in Fiscal 2001

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.
