We interviewed management and other persons we deemed appropriate and inspected the documentation available. Our work notably consisted in assessing the consistency of the main stakeholders identi fi ed by the Group with the nature of its activities and its geographical location, taking into account its business relationships and value chain. Concerning the identi fi cation of impacts, risks and opportunities (IROs) The information relating to the identi fi cation of impacts, risks and opportunities is mentioned in the Group management report and set out in section 4.1.5.2 “Double materiality analysis methodology” of Chapter 4 of the Annual Activity Report. We have reviewed the Group’s process for identifying actual and potential impacts (positive and negative), risks and opportunities (“IROs”) in relation to the sustainability issues set out in paragraph AR 16 of ESRS 1 “Application requirements” and, where applicable, those speci fi c to the Group. In particular, we assessed the approach taken by the Group to determine its impacts and dependencies, which may be a source of risks or opportunities. We reviewed the Group’s risk mapping of identi fi ed IROs, including a description of their distribution in the Group’s own operations and value chain, as well as their time horizon (short, medium or long term), and we assessed the consistency of this mapping with our knowledge of the Group and with the risk analyses it has carried out. We assessed the way in which the Group considered the list of sustainability topics listed in ESRS 1 (AR 16) in its assessment. Information relating to the assessment of impact materiality and fi nancial materiality is mentioned in the Group management report and set out in section 4.1.5.2 “Double materiality analysis methodology” of Chapter 4 of the Annual Activity Report. Through interviews with management and inspection of the available documentation, we obtained an understanding of the impact materiality and fi nancial materiality assessment process implemented by the Group, and assessed its compliance with the criteria de fi ned by ESRS 1. In particular, we assessed the way in which the Group has established and applied the materiality criteria de fi ned by ESRS 1, including those relating to the setting of thresholds, in order to determine the material information disclosed in respect of indicators relating to material IROs identi fi ed in accordance with the relevant topical ESRS.
