Environmental Accounting

Costs associated with environmental conservation
(Environmental accounting)

Nippon Steel has adopted environmental accounting to be used as guidelines for corporate activities, and to accurately track the environmental costs and effects. Environmental conservation costs, which combine the costs of capital investment associated with environmental measures, energy-saving measures, and recycling measures, and expenses incurred to conserve the environment, totaled ¥185.0 billion in fiscal 2022: ¥17.4 billion for capital investment and ¥167.6 billion for environmental conservation. Details for environmental conservation costs are listed below.

It is difficult to quantify environmental preservation effects in monetary terms, since such calculation would require many assumptions. Therefore, environmental preservation performance is kept track of as effects taking environmental measures, which are reported in this report and on our website.
