The selection of the GRI indicators to include took place on the basis of a careful examination of the informational purpose of each of them and their relevance to Terna’s activities and the interests of its stakeholders. In effect, the Report ideally addresses all the stakeholders identified in the Company’s Code of Ethics.

In particular, the information to be included to allow the stakeholders to make a balanced assessment of the Group's performance is identified using the principle of materiality through an internal process which included:

  • analysis of the Group's activities and any disputes, by reviewing the contents reported in internal communications instruments (team briefing documents, Terna News, Intranet, communications from Top Management) and external communication (Press Releases) and in the press;
  • analysis of internal reporting on aspects of sustainability (monitoring of and improvement plans for the environmental and safety management systems);
  • verification of the expectations of stakeholders through the stakeholder engagement activities described in this Report;
  • comparison with the performance of other companies through the reports of sustainability rating agencies and the development of benchmarking analyses;
  • meetings with Directors and Department Managers to explore significant aspects and emerging problems.
