Report details

The structure of the Report is organized with a view to presenting quantitative and qualitative data about the performance of MYTILINEOS in meeting key Environmental, Social and Governance (ESG) criteria and has been prepared in accordance with the GRI Standards "Core" option. [GRI 102-54]

The data and information presented in the Report are initially collected using the procedures and scientific capture methods applied in each Business Unit and subsidiary of the Company, as well as from the databases kept in the context of the implementation of the respective central corporate systems. The data are then forwarded through the integrated management system for the disclosure of non-financial performance, which consists of a software platform developed in-house (custom-configured Excel files based on the GRI Standards).

The calculation of the data composing the non-financial performance indicators included in the Report generally follows the definitions and the methodology described in the respective GRI and SASB Standards. The data are checked and verified using the SAP system (where available), as well as using internationally accepted verification methods which the Company has available, such as the ISO 45001 Occupational Health and Safety Management Systems Standard, the ISO 14001 Environmental Management Systems Standard, and the ISO 9001 Quality Management Systems Standard that the Company has established. Also, data from direct measurements or estimates are included, while for comparison purposes use is primarily made of three-year historical data. Performance results at top level are calculated by consolidating (aggregating the relevant quantities) the individual data obtained from the Business Units and subsidiaries of the Company.

The content focuses on the sustainability topics which are of material significance for the achievement of the strategic goals of MYTILINEOS and which have been identified based on the Company’s formal Materiality process, in accordance with the GRI Standards: [GRI 102-40] to [GRI 102-47]. The information presented in the Report is supplemented by the required references to the Company's Annual Report 2021. Some figures have been rounded for reasons of consistency and better visualization.

Specifically for the Metallurgy Business Unit, throughout the scope of this Report, the data concerning the certification of the Aluminium Stewardship Initiative (ASI) plant will be accompanied by the badge: ASI.
