To obtain the "sustainable success" that by now represents the principle of reference of the new corporate governance code for listed companies, large enterprises and SMEs must initiate a true process of change able to involve business, governance, and corporate strategy. The growing pressure from ESG investors, the size of companies, and the presence of independent board members are key elements for the integration of sustainability into business strategy and are strictly correlated with the definition of a sustainability plan, the conduct of stakeholder engagement activities, and the presence of a sustainability committee. Most Italian SMEs show growing interest for themes linked to sustainability. However, they are not yet ready to fully integrate these aspects into their corporate governance and to begin spreading them through NFR.
