Basic Concept on Environmental Accounting

  • The Sumitomo Rubber Group

The Sumitomo Rubber Group has introduced environmental accounting in order to promote environmentally friendly corporate activities while maintaining good relations with society.
Environmental accounting is a framework for quantitatively evaluating a company's environmental preservation efforts, and our group measures costs and other factors in accordance with the guidelines of the Ministry of the Environment.
In order to promote environmental preservation efficiently and effectively, it is important for the government, companies and consumers to cooperate with each other and disclose environmental information. Our group values environmental accounting not only as a management tool, but also as a tool for communicating with society.

Fiscal 2023 Environmental Accounting

Environmental Preservation Costs (millions of yen)

Category Fiscal 2023
Investment Expenses

1. Costs incurred for activities undertaken within business bases

 Costs for desulfurization and wastewater treatment equipment, etc. 848 2,552

2. Upstream and downstream costs

 Costs for disposal of waste tires and the commissioning of container packaging, etc. 3 154

3. Administrative costs

 Costs for the maintenance of EMS, etc. 0 119

4. R&D costs

 Costs for the development of eco-friendly products, etc. 0 2,160

5.Costs for social contribution activities

 Costs for greening activities 2 218

6. Other costs for environmental preservation

 0 20
Total 853 5,224

The environmental preservation costs incurred during fiscal 2023 consisted of approximately ¥0.9 billion in capital expenditures executed to prevent pollution (e.g., the installation of dust collectors and wastewater treatment equipment), curb global warming (e.g., energy-saving measures), and promote resource recycling (e.g., installation of boilers fueled by waste tires and poly-sheet restoration equipment), as well as approximately ¥5.2 billion spent for facility maintenance and management, including that of cogeneration systems, waste tire-fueled boilers, and coolant water circulation equipment.

Environmental Preservation Effects in Terms of Overall Reductions in CO2 and Waste Emissions (in comparison with the absence of improvement measures)

Category Item Volume of year-on-year reductions
Global environmental preservation CO2Volume of CO2 emissions (t-CO2) 11,340
Energy consumption volume in crude oil equivalent (kl) 6,546
Volume of organic solvent emissions (t) -4
Resource recycling Volume of landfill waste (t) Maintaining complete zero emissions
Volume of waste emissions (t) 1,290
Volume of wastewater discharge (thousand m3) -119

In fiscal 2023, our global environmental preservation activities resulted in reductions of 11,000 tons in the volume of CO2 emissions as well as 7,000 kl in the volume of energy consumption in crude oil equivalent, respectively. These achievements are attributable to the success of energy-saving efforts and the impact of lower production volume. On the other hand, the volume of organic solvent emissions increased by 4 tons. In terms of resource-recycling initiatives, our six factories in Japan achieved complete zero landfill waste (Note 2) the 19th consecutive year since fiscal 2005. Thus, these factories successfully maintained the complete zero-emission status in terms of the volume of waste disposed of by direct landfill. In addition, the volume of waste emissions decreased by 1,290 tons, while the volume of wastewater discharge increased by 119,000 m3.

(Note 2)Complete zero landfill waste: 100% recycling rate and no waste sent directly to landfills. (The Group has defined the overall volume of waste disposed of for the purpose of recycling purposes as the volume of recycled waste.

Economic Effects of Environmental Preservation Measures (millions of yen)

Category Measures Economic effects
Cost reductions via energy saving Introduction of cogeneration systems, the implementation of energy-saving activities 275
Recycling and the reduction of bulk, etc. Waste reduction and recycling, proceeds from the sale of valuables 1,396
Total 1,671

In fiscal 2023, the economic effects of environmental preservation measures consisted of approximately ¥0.3 billion arising from energy-saving activities and approximately ¥1.4 billion arising from recycling and the reduction of bulk, etc.
