Note on methodology

The Iren S.p.A. 2021 Sustainability Report, referring to the period 1 January – 31 December 2021, also constitutes a Consolidated Non-Financial Statement (NFS), pursuant to Italian Legislative Decree 254/2016.

The document was prepared in accordance with the Global Reporting Initiative (GRI) Standard: Comprehensive Option and the Electric Utilities Supplement – G4 Sector Disclosure.

Starting with this edition, the Sustainability Report integrates the transparency information required by the European Taxonomy (EU Regulation 2020/852 and EU Delegated Regulation 2021/2178) regarding the managed activities considered sustainable (see page 120) and reports the main indicators related to the projects financed by the Green Bonds issued by Iren Group (see page 124).

In addition, it includes, in line with the recommendations of the Financial Stability Board’s Task Force on Climate-related Financial Disclosures (TCFD), information to clearly and transparently report the financial impacts of climate change on the Group (see page 80).

The document also provides extensive information on the management of the Covid-19 emergency 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 allows 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 2020 Report was published in April 2021) 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 2021 was approved by the Board of Directors, along with the draft of the Consolidated Financial Statements, on 29 March 2022, assessing its completeness and consistency with the topics identified in the materiality matrix.
