Note on methodology

The Iren S.p.A. 2020 Sustainability Report, referring to the period 1 January – 31 December 2020, also constitutes a Consolidated Non-Financial Statement (NFS), pursuant to Italian Legislative Decree 254/2016.

The document was prepared, under the coordination of the Corporate Social Responsibility and Local Committees Department, in accordance with the Global Reporting Initiative (GRI) Standard: Comprehensive Option and the Electric Utilities Supplement – G4 Sector Disclosure. This Report adopts, one year in advance, Standard 306 “Waste” published in 2020.

The Sustainability Report also contains the indicators needed to report on the projects financed by the Green Bonds issued by the Iren Group (see page 66 of the “Sustainability Report”).

The document provides extensive information on the management of the Covid-19 crisis and the resulting impacts, in relation to Consob’s Call for Attention (no. 1 of 16/2/2021). The relevant information is highlighted with dotted lines to the side.

The data are reported through the “Sustainability Report – NFS” application, which facilitates the tracking, verification and approval of all required data.

The Sustainability Report/NFS is prepared annually by Iren Group under the coordination of the Corporate Social Responsibility and Local Committees Department (the 2019 Report was published in April 2020) and approved by the Board of Directors together with the draft of the Statutory Financial Statements and the Consolidated Financial Statements.

The Sustainability Report/NFS 2020 was approved by the Board of Directors, along with the draft of the Consolidated Financial Statements, on 25 March 2020, assessing its completeness and consistency with the topics identified in the materiality matrix.

The document was audited by the appointed auditor PricewaterhouseCoopers S.p.A. pursuant to Italian Legislative Decree 254/2016 based on the principles and indications contained in ISAE3000 (International Standard on Assurance Engagements 3000 – Revised) of the International Auditing and Assurance Standards Board (IAASB).

PricewaterhouseCoopers S.p.A. is also the company appointed to perform the legal audit of Iren’s Consolidated Financial Statements.
