  1. *1Because there were some corrections to the results, Scope1, Scope2, the amount of power used, and energy consumption have been retroactively corrected.
  2. *2The coefficients referenced when calculating Scope1 and Scope2 are the following.
    Fuel emission factors:
    (Japan) Greenhouse gas emission quantities based on “List of Calculation Methods and Emission Factors for Greenhouse Gas Emissions in the Calculation, Reporting and Publication System” from the Ministry of the Environment are used.
    (Overseas) “2006 IPCC Guidelines for National Greenhouse Gas Inventories” are referenced for the fossil fuel unit calorific values and carbon intensity.
    Electrical power emission factors:
    (Japan) The adjusted emissions factor in the emission factors for each electrical power company is used.
    (Overseas) The CO₂ emissions factor for each country as reported by the International Energy Agency (IEA) is used.
  3. *3Scope3 is disclosed only for limited categories where it was judged that calculation is possible.
  4. *4 Increased as a result of acquiring fixed assets following the merger with the former NS Architectural Steel Services Corporation.
  5. *5This is 0 because it is included in Scope1 and Scope2.
  6. *6This is 0 because there is nothing which would be classified as a franchise business.
  7. *7Out of the total amount of power used, this calculates the percentage of power used with a CO₂ emission coefficient of 0, such as solar power and CO₂-free power contracts.
  8. *8A unit calorific value for electrical power of 3.6 GJ/MWh is used. Consumption of power from renewable energy sources is not included. Calculations for fuel are made using the unit calorific values in the Act on the Rational Use of Energy.
