Environmental Accounting

  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, 2007 - March 31, 2008
  • 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.

2. Environmental conservation costs

5. Costs of social activities Environmental maintenance cost, including vegetation
The cost of publicity
0 10.2
6. Cost of environmental damage Cost of restoring natural environments 0 0
Total 29.3 1,043.1



3. Effects

(Economic effects Unit: Million yen)

2. Reduction of city gas (1,000m³) -23.9 -2.1
3. Reduction of consumption of tap water and well water (1,000m³) -3.6 -1.4
4. Resources recycling and reduction of wastes

(2)Industrial waste
(3)General waste from business activities



5. Valuable resources (1000kg) 430.1 22.9

4. Report of results

The total cost of the management activity cost has increased substantially because the number of research and development items has grown in scale and an increasing number of items have been intended to respond to environmental requirements despite the reduced manpower cost for environment management, and so on. The objectivity of the calculation of the environmental proportion has also been enhanced by the design method used.

In terms of the environment conservation effect, however, despite the substantial reduction in the quantitative effect for electric power, that for utility gas has been slightly increased. For waste, the volume of industrial waste subject to special control has been reduced by recycling solvents, and so on. The total amount of industrial waste has been substantially increased due to the increase in wasted dry cells and construction waste, despite the reduction in wasted fluorescent tubes and batteries.

The volume of general waste from business activities has dropped substantially. For valuable resources (aluminum scrap, copper scrap, steel and gold plating, etc.), however, although the amount has declined slightly, the sums concerned have been maintained at virtually the same level thanks to recycling activities. Consequently, though the economic effect of waste remains positive on a continual basis, the total economic effect has been reduced, partly due to the sharp rise in energy prices.
