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, 2010 - March 31, 2011
  • Range of accounting: Japan Radio Co., Ltd. Mitaka and Saitama Plants
  • 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
Compared to the previous fiscal year, both capital investment and the cost of the business area decreased slightly, as did the cost of the management activity. While the cost of research and development decreased by just over 35%, we engaged in capital investment to functionally improve the aggregation system for hazardous chemicals. Consequently, compared to the previous fiscal year, the total environmental conservation cost of the capital investment decreased slightly, while that for the cost decreased by just under 30%.

(2) Environmental conservation effect
Compared to the previous fiscal year, the "substantial effect" of electric power, city gas and clean and well water decreased slightly, while that from heavy oil and industrial waste increased slightly. The collective "economic effect" of all of electric power, city gas, clean and well water and heavy oil decreased. Regarding valuables (scrap aluminum, copper and iron and gold-plated materials), the "substantial effect" increased by just under 20% compared to the previous fiscal year, while the "economic effect" increased by just over 50%. Consequently, the total economic effect was a modest minus from the significant plus the previous fiscal year.
