Report structure and content

This report is aligned with Global Reporting Initiative (GRI) Standards for stakeholder inclusiveness, sustainability context, materiality and completeness. It focuses on the 14 material topics of our sustainability strategy (see Sustainability strategy), which are aligned with our business priorities. We identified these topics in 2020 through a materiality exercise that considered the sustainability context and involved a review of stakeholders’ concerns (see Stakeholder engagement). For each material topic, we define ambitions and goals, and implement programs. In response to our stakeholders’ expectations and for a better understanding of our performance, we disclose data and information from previous years. We also include examples of actions we have carried out at ST sites, as well as quotes from stakeholders, enabling them to express their own views on our sustainability performance. I 102-46 I 102-49 I

The report has been prepared in accordance with the GRI Standards: Core option. We use labels to disclose GRI Standards throughout the report and we list all references to GRI Standards and the corresponding page numbers in the GRI content index. I 102-54 I

Our disclosures are also aligned with the Sustainability Accounting Standards Board (SASB) semiconductor standard and the Task Force on Climate-related Financial Disclosures (TCFD) framework.
