Although the definition of material issues has been revised, in line with the updated GRI standards, to focus on impact, the engagement of relevant stakeholders continues to be part of the process of identifying and assessing corporate priorities. This took shape through stakeholder engagement, a two-stage process:

• Identification of different categories of stakeholders. This phase was carried out following the AA1000 Stakeholder Engagement standard (AA1000SES) 2015 and led to the identification of the categories in the following table, each accompanied by its description.

Stakeholder	Definition
Worker	Employees working for or on behalf of PSC, including its representatives (e.g. trade unions)
Supplier	Provider of products or services to PSC
Customer	Customers of PSC products
Investor	Who holds shares within PSC
Society and local communities	The social context in which PSC sites are located. It can influence its activities
Institutions	The set of institutions that can influence the PSC activities (e.g. Region, Province or Municipality in which PSC sites are located)
NGO and Associations	Non-profit associations and private organizations operating in areas that influence PSC activities (e.g. environmental associations or sector associations)
Media and press	International, national and local media (e.g. television, press, radio and web) which PSC can use to communicate its initiatives

• Definizione delle modalità di attuazione dell’engagement. Nel 2022 sono state coinvolte direttamente le categorie dei lavoratori, dei fornitori e degli investitori, ai quali è stato sottoposto un questionario che ha indagato la rilevanza dei temi materiali in termini di impatti connessi. Per le altre categorie di stakeholder si è fatto ricorso a modalità indirette di coinvolgimento: è stata selezionata e analizzata la documentazione utile a ricostruire le opinioni e le istanze sui temi materiali.

This is followed by the list of material topics in the order of priority assigned by management, along with the ratings assigned by stakeholders.

The analysis of impacts brought out new thoughts on the importance of certain issues, such as waste management and energy consumption, which were found to be the most important. The issue of workers’ health and safety is also confirmed as a priority. Stakeholders confirm the importance of prudent management of energy consumption, an issue that is very important in 2022 due to ongoing international events. Much importance is also given to innovation, compliance and the topic of atmospheric emissions.
