Environmental Action Report 2003

Environmental accounting is a way to estimate costs and conduct a cost-benefit analysis on environmental activities. To promote environmental activities more effectively, TohokuEPCO is continuously reviewing and improving the accuracy of its environmental accounting.
We will continue our study and review process on environmental accounting in order to ensure greater accuracy and more effective application of the results.

Results for FY 2002

Category	Principal Measures	Costs (billion yen)		Benefits
Category	Principal Measures	Investments	Expenses (*1)	Benefits

Protection of the regional environment	Preservation of air quality (reduction of SOx, NOx and soot); Urban landscaping measures; Environmental inquiries, etc.	4.82	28.03	SOx Reduction: 110,000 tons NOx Reduction: 42,000 tons Soot Reduction: 726,000 tons
Others	Environmental activities for the regional community; Environmental management; Environment-related R&D, etc.	-	2.1	-
Total		6.78	42.9	-

(*1) Depreciation expenses are included, and personal expenses required for environmental measures are distributed to each category.
(*2) Costs required for the reduction of CO2 emissions by nuclear, hydroelectric, geothermal and LNG-fired thermal power stations are not included, because of the difficulty in identifying specific costs.
