JRC began aggregate calculation of environmental accounting in 2001 and is working to achieve efficiency in its environmental activities in terms of both cost and effect.

1. Accounting conditions

  • Period covered: April 1, 2009 - March 31, 2010
  • Range of accounting: Japan Radio Co., Ltd. Mitaka Plant and Saitama Plant
  • Basic concepts: Guidelines for Environmental Accounting, 2005 edition (Ministry of the Environment)
  • Only costs of the measures taken for the purpose of environmental conservation should be included in the accounting.
  • Depreciation costs of environmental facilities are included.
  • Only substantial impacts (reduction impacts, income from selling valuable resources) should be included, but estimated impacts should not be included.
  • The effect shown in terms of the consumption of electric power, city gas, drinking water supply and water from wells should cover not only the facility investment but all environmental activities.

4. Report of results

(1) Environmental conservation cost
Among costs in business areas, capital investment was decreased by 50% and the cost fell more than 20% compared with the figure for the previous fiscal year, while the costs of management activities and research and development increased by nearly 10%. Moreover, as capital investment for research and development, we have introduced a system of aggregation of hazardous chemical substances to focus on responses to REACH regulations. Consequently, among the total cost for environmental conservation, capital investment declined by more than 30% and the cost increased more than 2% compared with that of the previous fiscal year.

(2) Environmental conservation effect
The quantitative effect has been improved because of substantially reduced consumptions of electric power, city gas, tap water / well water, and heavy oil compared to the previous fiscal year, while the reduction rate of specially controlled industrial waste decreased. The reduction rate of industrial waste was improved by significantly reduced volumes of construction waste, discarded fluorescent tubes and batteries.

The economic effect of waste has been substantially improved due to reduced costs via a significant rise in the quantitative effect from electric power, city gas, and tap water / well water, as well as a sharp decline in industrial waste. For valuable resources (aluminum scrap, copper scrap, steel scrap and gold plating, etc.), however, the purchase volume has declined by about 15% compared to the level of the previous fiscal year and the purchase cash equivalent has declined by about 50% due to the price slump in the metal market. Consequently, the total economic effect has become overwhelmingly positive, despite being negative in the previous fiscal year.
