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, 2006- March 31, 2007
  • 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, and unexpectedly, those contributing to environmental conservation are excluded.
  • 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

The personnel cost of environmental control for management activity cost were reduced by half. However, the total cost increased as research and development costs into environmental requirement increased.

Concerning the "substantial effect" of environmental conservation effects, a small increment was observed on the electric power, but a reduction in city gas. Concerning waste, we significantly reduced the volume of waste from solvents by reusing them. The quantity of wasted fluorescent tubes increased, while a significant reduction emerged in the volume of wasted dry batteries, especially wasted construction materials and batteries. The volume of valuable resources (scraps of aluminum, copper, steel and gold-plated articles) sorted out of wastes increased due to recycling activity. Consequently, the "economic effect" of waste turned positive and the economic effect significantly improved as a whole.
