¹The specific CO₂ emissions of primary Aluminium are calculated in the context of the participation of the Metallurgy Business Unit of MYTILINEOS in the international initiative ASI (Aluminum Stewardship Initiative) and according to the Aluminum Carbon Footprint Technical Support Document (WA, Feb-2018), of the International Aluminum Institute, for the LEVEL 1 approach. It includes the activities of smelting, casting and anodes production. ² Includes revenue from activities which meet the eligibility criteria as defined by the EU Taxonomy. The EU taxonomy is a classification system, establishing a list of environmentally sustainable economic activitieswiththe aim toscale up sustainable investment and implement the European Green Deal. ³ It relates to the emissions that would occur in the absence of MYTILINEOS RES projects. It is calculated through the multiplication of the energy produced (MWh)by the renewable energy projects (solar, wind, small hydro (<10MW)) which are in operation, and the convention factor of electric energy to CO2e based on the Country’s energy mix in the reporting year. ⁴ The difference between the total amount of fresh water withdrawn and the total amount of fresh water discharged. Fresh water is the water with concentration of total dissolvedsolids equal to or below 1,000 mg/L. New calculation method, according to the standard GRI 303-5 (2018). ⁵ Number of voluntarydepartures to the average number of direct employees of the Company in the specific year. Cases of expiration of fixed-term contracts are not considered as voluntary departures. ⁶ The calculation method used for measuring accidentsis 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 consciousness or significant injury or ill health diagnosed by a physician or otherauthorized health professional. Includes all accidents and incidents that occurred during the transportation of the employee from the place of his private activity (e.g. residence) and a workplace and only 33when this transportation has been organized by the Company. ⁷Percentage on the Company's executive staff.
