Basic approach

Recognizing that our business activities affect the entire planet and that protecting the global environment is essential for our survival and activity, we work voluntarily and proactively to protect the environment under the Nisshin Seifun Group's Basic Environmental Policy, including initiatives to reduce waste and CO₂ emissions and to effectively use resources and energy.

Calculation methods

Total energy used (Japan/overseas)

For each type of energy, we used the annual amount of energy used multiplied by the relevant conversion factor. Total energy used is calculated from the sum of these.

Total materials used (Japan/overseas)

Calculated using the sum of total production and total waste.

CO₂ emissions related to manufacturing (Japan/overseas)

Since fiscal 2023, we have changed from location-based to market-based emission factors relating to the use of electric power at operation sites in Japan. These figures are calculated using emission factors published by individual electric power companies. For overseas, we use emission factors published by individual electric power companies in the regions where our operation sites are located. If those emission factors are unavailable, we use country-specific emission factors published by the IEA.

CO₂ emissions related to product transportation (Japan)

We calculate emissions from carriers designated under Japan’s Energy Efficiency Act (Nisshin Flour Milling Inc., Nisshin Seifun Welna Inc., and Oriental Yeast Co., Ltd.).

Reference guidelines for other emissions

Calculated using Greenhouse Gas Protocol (WRI)

Total Waste (Japan/overseas)

Calculated by adding together industrial waste, municipal waste, and recovered valuable material.

Chemical substances (Japan)

Volume calculated using the pollutant release and transfer register.

Total liquid effluent (Japan)

The sum of the amount of water discharged by each business site into public water systems.

BOD (Japan)

The total amount of biochemical oxygen demand, which indicates the amount of pollutants in water.

Independent assurance of environmental data

The Nisshin Seifun Group conducts numerous audits from the perspectives of food safety, quality control, and environmental management. These audits, which include environmental data, are carried out both internally and by external organizations. The Group’s figures for CO₂ emissions, energy use, water consumption, and waste in Japan and overseas undergo third-party verification each year by Sustainability Accounting, Co., Ltd. We will continue to improve our disclosure of non-financial information by reviewing the scope and methodology of calculations, and the items that are included.
