*¹ For the calculation of the ratio, the CO₂ emissions (scope 1&2) taken into account are those of of bauxite mining activities, primary and secondary aluminium production.* ² It includes income derived from activities that meet the eligibility criteria for inclusion in the list of activities as defined by the EU Taxonomy. The EU Taxonomy is a classification system that creates a list of environmentally sustainable economic activities in order to increase sustainable investment and the implementation of the European Green Deal. ³ It refers to the CO₂ emissions avoided from two of the Company's main activities. They are calculated from the emissions that would have resulted from the absence of Metlen' renewable energy production and from the production of secondary aluminium, the absence of which would have led to its replacement by primary aluminium. The calculation up to 2022 concerned only the CO₂ emissions avoided by the Energy sector, the calculations for 2023 have included the CO₂ emissions avoided by the production of secondary aluminium in substitution of primary aluminium ⁴ The difference between the total amount of fresh water withdrawn and the total amount of fresh water discharged. Fresh water is defined as water with a total dissolved solids concentration equal to or less than 1 000 mg/l. The methodology for calculating this indicator is in accordance with GRI 303-5 (2018) ⁵ Number of voluntary departures as a percentage of the average number of direct employees of the Company in the specific year. Cases of termination of fixed-term contracts are not considered voluntary departures. ⁶ The calculation method used for measuring accidents according to the standard GRI 403-9 (2018). Includes all accidents that resulted in death, days off work, limited work or transfer to another job, medical care other than first aid or loss of consiousness or significant injury or ill death diagnosed by a physician or other authorized health professional. Includes all accidents and incidents thta occured during the transportation of the employee from the place of his private activity (e.g. residence) and a workplace and only when this transportation has been organized by the Company. *⁷ Percentage on the Company's executive staff.* ⁸ The index has been calculated based on the methodology of S&P Global's Corporate Sustainability Assessment. In more detail: Human Capital ROI = (Total revenue - (Total operating expenses - Total expenses related to direct employees)) / Total expenses related to direct employees. ⁹It calculates the socio-economic generated value of a programme or action. It tells the story of the "Theory of change" that the activity has brought to everyone involved, through the measurement of social, environmental and economic outcomes and uses monetary values to evaluate them.
