Philosophy of 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. The iron and steel industry is an equipment-intensive industry. We have achieved environmental preservation and energy conservation by installing environmental-friendly equipment such as dust collectors and improving the efficiency of production equipment. Costs of environmental preservation are quantified by adding the costs of capital investment associated with environmental measures, energy-saving measures, and recycling measures to expenses incurred to preserve the environment.
Environmental preservation costs
For FY2020, capital expenditures for environmental preservation amounted to 19.4 billion yen in total, or approximately 4% of the company’s capital expenditures. Investment in equipment for environmental measures of 17.0 billion yen include preventive measures for dust emissions, visible smoke emitted from steelworks stacks, extream water discharge from drain outlets, and leakage of water from the revetments and quay walls at steelworks. Investment in energy-saving equipment of 2.4 billion yen comprises measures to improve the efficiency of reheating furnaces as well as overall energy-saving measures in each manufacturing process.
Environmental preservation costs totaled 101.2 billion yen, including 53.4 billion yen in air pollution prevention costs, 11.3 billion yen in water pollution prevention costs, 2.1 billion yen in energy-saving measures, and 13.2 billion yen in environmental R&D costs. Expenses for waste disposal were reduced by promoting in-house recycling.
