  1. *1 The thermal equivalent values of energy consumption other than city gas in 2023 are based on the heating value per unit in the Enforcement Regulations of the Law Concerning the Rational Use of Energy and Conversion to Non-Fossil Energy. Accordingly, the usage for 2019 to 2022 is recalculated in the same way (For heating value per unit, see “Greenhouse Gas Emissions Per Unit”). Heating value per unit for sustainable electricity is the usage level of electricity purchased from electric utility companies defined in the Enforcement Regulations of the “Act on the Rational Use of Energy”(0.00864 GJ/kWh).

Lost-worktime Injury Frequency rate, Occupational incidence severity and Occupational Illness Frequency rate

Social performance indicator Calculation method
Lost-worktime injury frequency rate Number of people injured or killed in occupational accidents per 1 million work hours (resulting in at least one work day off, and an application for accident compensation insurance, but excluding accidents during commuting), showing the frequency of occurrence
Injury frequency rate = number of people injured or killed in occupational accidents / total number of actual working hours*1 x 1,000,000
Occupational incidence severity Number of days of work lost to occupational accidents (excluding accidents during commuting) per 1,000 work hours, showing the severity of the accident
Occupational incidence severity = number of workdays lost / total number of actual working hours*1 x 1,000
Occupational Illness Frequency rate Number of occupational diseases per 1 million work hours (calculated based on persons certified as occupational accidents) represents the frequency of occurrence of occupational diseases.
Occupational diseases are stipulated in Article 35 of the Ordinance for Enforcement of the Labor Standards Act in Japan.
Occupational Illness Frequency rate = number of occupational diseases / total number of actual working hours*1 x 1,000,000
  1. *1 When the number of actual working hours of temporary employees is unknown, it is estimated by multiplying the number of such workers as of December 1 of the relevant year x 7.75 hours/day x working days.

Fatalities
