(Environmental Accounting)Yamaha Group

  Yamaha Corporation introduced environmental accounting in fiscal 1999 as a means of quantitatively evaluating the effectiveness of its environmental conservation activities. These environmental accounting practices were then implemented at Yamaha Group manufacturing companies and resort facilities in Japan, and since fiscal 2004 they have also been implemented at some overseas Group production sites.

  • *1  Equipment investment refers to investment in factories and equipment made for environmental conservation objectives. The figure is calculated by multiplying the purchase price of individual pieces of equipment by a figure determined by the proportion of the environmental conservation purpose to the whole purpose of the purchase of such equipment (e.g., 0.1, 0.5, 1.0).
  • *2 Expenses refer to personnel and other costs expended for environmental conservation activities. Personnel expenses are calculated by multiplying the time spent on environmental conservation activities determined by the manager of each department by a common unit cost of personnel expenses set in each company. Costs are determined by multiplying the amounts paid externally by a certain figure calculated using a proportional distribution method as in the case of investment amounts (e.g., 0.1, 0.5, 1.0). Depreciation costs are not included.
