Environmental accounting

We employ environmental accounting to make a quantitative analysis of the costs and effectiveness of environmental preservation activities involved in our business activities and utilize this analysis as a guide in our corporate activities.

As for the cost of the environmental conservation program in the FY2022, we injected 75,381,000 yen for the facility investment and 1,546,828,000 yen for the cost and the economic effects resulted in a variation of -420,949,300 yen.

Effects for environment preservation

Unit: Thousand yen

Area Description Reduction in environmental load * Monetary value of effect How the monetary value of effect was calculated

Real effect

Energy (crude oil equivalent) -647kl -408,818 The sum total of savings on electric charges, waste disposal costs etc., as compared with the previous year's results, and proceeds from the sales of valuable scraps.
Industrial waste -60t 4,559
Service water -66千m³ 5,339
Deemed effect Discharge (BOD, SS, oil, N-HEX) -182kg -22,029

Assign a weight to each substance as a cadmium equivalent based on standards specified in environmental laws and regulations and ACGIH-TLV (the threshold limit value for each substance specified by American Conference of Governmental Industrial Hygienists), and multiply by possible damages for cadmium pollution.

Convert a reduction in environmental load to air, water, soil, etc., into a monetary value so different types of environmental load can be compared with one another by the same standard.

Air (soot and dust, nitrogen oxide, sulfur oxide) 2kg -0.3


*The environmental load reduction amount refers to the difference between the amount of FY2021 and that of FY2022. The negative value indicates an increase of the environmental load.
