  1. *Coal intensity is the amount of coal consumed divided by the electric power sales volume of thermal power plants.
  2. *The intensity for NOx, SOx, and soot and dust is calculated based on the amount of electricity generated at thermal power plants, which are the source of emissions.
  3. *For N2O and SF6, we have revised the emission coefficient, global warming coefficient, and emission activities covered by the accounting and reporting system from the FY2023 data, in response to the revision to the ministerial ordinance on GHG emission calculation based on the Act on Promotion of Global Warming Countermeasures.

Calculation Methods in Each Scope 3 Category

  1. (1)Calculated by multiplying each product or service purchased by respective emission factor
  2. (2)Calculated by multiplying the capital investment by the emission intensity
  3. (3)Sum of the following two values
    1. 1)Emissions from production and transportation of fuel used by the company
    2. 2)Calculated by multiplying the amount of electricity procured from sources other than the company by the emission intensity
  4. (5)Calculated by multiplying the amount of emissions by waste type by the emission intensity of each treatment method
  5. (6)Calculated by multiplying the number of employees by the emission intensity
  6. (7)Calculated by multiplying the number of employees and number of business days by type of work and by rank of employee, respectively, by the emission intensity
  7. (9)Calculated by multiplying the ton-kilometers of sold coal transported by the emission intensity
  8. (11)Calculated by multiplying the volume of coal sold by the emission intensity
  9. (15)CO2 emissions from power plants in which J-POWER’s equity portion is less than 20%
