305-1+305-6 CH4 (purges) Potential global warming value of CH4 defined by the Intergovernmental Panel on Climate Change (IPCC 2013): 28 tCO2eq (considering a composition of 87.89% CH4 in Natural Gas).
305-1+305-6 SF6 (leaks) Potential Global Warming Value of SF6 defined by European Parliament and Council Regulation (EC) No 517/2014 of 16 April 2014 on certain fluorinated greenhouse gases: 22,800 tCO2eq
305-3+305-4 Other indirect emissions of greenhouse gases Use of data from the travel agency on the calculation of greenhouse gas emissions. The calculation of CO2 is based on the trip/number of miles multiplied by 0.289 (carbon footprint reference value): 319 x 0.289 = 92.19 ( kg CO2).  

The reference value of 0.289 was calculated in accordance with the GHG Protocol, e.g.: the number of miles flown is multiplied by 1.61 to determine the number of kilometres travelled. In order to determine greenhouse gas emissions, the number of kilometres is multiplied by the emission factor equal to 0.18 kg CO2 per km.
401-1 Rotation rate Σ people leaving the company + Σ people joining the company /2/ average headcount (full contract workers + term + interns).
403-2 Absenteeism rate
Ratio of the sum of paid leaves of absence (due to illness, accident, maternity and other reasons) and unpaid absences, divided by the total number of theoretical working hours. Hours of absence = hours not worked due to Illness, Work Accident, Personal Matters and other absences, paid and unpaid.
Hours not worked as a result of parental leave and hours justified on family grounds (assistance for children, marriage and death) are not included in the calculation.
403-2 Incidence rate Measures the number of fatal and non-fatal occupational accidents occurring in a given period per one thousand employees at risk in that same period.
403-2 Total severity rate Measures the number of days lost through non-lethal and lethal accidents (1 lethal accident = 7 500 days lost) accounted for in a specific period per million hours worked.
403-2 Severity rate Measures the number of days lost through non-fatal accidents that occur in a given period of time per every million hours worked during the same period.
403-2 Potential workable hours Number of hours theoretically workable based only on the normal working period of workers on working days in the year (excluding holidays and public holidays).
404-1 No of Hours of training per Employee Σ Hours of training / average headcount (full contract workers + term +interns).
EU28 Average frequency of system interruption (SAIFI)
Ratio of the total number of interruptions at delivery points, during a specific period, divided by the total number of  delivery points in the same period.
Electricity: SAIFI corresponds to the average number of accidental interruptions greater than three minutes seen at delivery points during a specific period of time. Gas: Average No of interruptions per output point - ratio between the total number of interruptions at output points during a specific period, divided by the total number of output points at the end of the period under consideration.
EU29 Average duration of supply interruptions (SAIDI)
Ratio of the sum of interruption times at delivery points, during a specific period, divided by the total number of  delivery points in the same period.
Electricity: SAIDI for a specific period of time (generally, one year) is the average accidental interruption time greater than three minutes at delivery points. Gas: Average duration of interruptions per output point (min/output point): ratio between the sum of interruption durations at output points during a specific period, divided by the total number of output points at the end of the period under consideration.
