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, 2011 - March 31, 2012
  • 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
Regarding the business area cost, while the capital investment increased significantly due to the introduction of the HVDC system, the cost dropped by just under 30%. Regarding the management activity cost, while the capital investment increased slightly due to the replacement of the canteen water meter, the cost was reduced by just over 10%. In addition, regarding the cost of research and development, while capital investment was generated due to the introduction of an information investigation support system for chemical substances, the cost was reduced by just over 35%.

From these result, regarding the total conservation cost compared with the last fiscal year, while the capital investment increased significantly, the cost decreased by just over 30%.

(2) Environmental conservation effect
Regarding the "substantial effect", while the reduction in electric power and city gas increased significantly, partly due to the impact of the Great East Japan Earthquake, heavy oil dropped slightly. In addition, industrial waste soared. Valuables (scrap aluminum, copper and iron and gold-plated goods, etc.) increased by just over 5%.
Regarding the "economic effect", electric power, clean water and well water, and heavy oil declined, affected by the decrease in clean water and well water resulting from the increased ratio of clean water usage. In addition, valuables rose by just under 15%.

Based on these results, the total economic effect saw a slightly increased negative value from the modest negative value in the last fiscal year.
