Material Balance

The table below shows the Nisshinbo Group’s business activities and environmental impact.
Environmental data sheets for principal subsidiaries are also published.

Material Balance

*1 Gigajoule (GJ): A unit of energy measurement. 1GJ=109 J=about 240,000 kilocalories

*2 Not including electricity sold under the feed-in tariffs scheme for renewable energy

*3 PRTR substances: Substances subject to the Pollutant Release and Transfer Register (PRTR) system pursuant to the “Act on the Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof” and reports of their amounts of release and transfer must be filed.

*4 Greenhouse gases

  • ・Scope1:
    • Energy-related Greenhouse Gas Emissions = Σ[Fuel Consumption x CO2 Emission Factor*4-1]
    • Non-Energy-related Greenhouse Gas Emissions = Non-Energy-related CO2 Emissions + Σ [Greenhouse Gas Emissions other than CO2 × Global warming potential *4-2]
      • *4-1 Emission factors based on the Act on Promotion of Global Warming Countermeasures are used. Coal, however, uses a factor (1.893 t-CO2/t) calculated based on actual calorific values.
      • *4-2 Global warming potential based on the Act on Promotion of Global Warming Countermeasures.
  • ・Scope2
    • Energy-related GHG emissions = Σ [purchased electricity and purchased steam volume x CO2 emission factor*4-3]
      • *4-3 Purchased electricity uses, in Japan, adjusted emission factors for each electric company based on the Act on Promotion of Global Warming Countermeasures in Japan, and the in foreign countries, the emission factors for each electric company, and if unavailable, the latest country-specific emission factors of IEA Emissions Factors. Purchased steam uses emission factors based on the Act on Promotion of Global Warming Countermeasures.
      • *4-4 The Nisshinbo Group decided to apply the emission factor by electric company or the emission factor of IEA Emissions Factors from fiscal year 2021, and retrospectively revised the emissions of greenhouse gases from 2014 onwards using the emission factor in the applicable year.

*5 Energy-derived greenhouse gas emissions: Greenhouse gas emissions due to fuel consumption.

*6 Non-energy derived greenhouse gas emissions: Greenhouse gas emissions due to reasons other than fuel consumption, e.g. manufacturing process, waste products, etc.

*7 Volatile Organic Compounds (VOCs): Emissions of volatile organic compounds such as toluene.

*8 Chemical Oxygen Demand (COD): Chemical Oxygen Demand, or Chemical Oxygen Consumption, is an indicator that shows water contamination levels.

*9 Suspended Solids (SSs): The amount of foreign substances floating in water.

*10 Transport volumes in international waters are not included.
