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 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 our sites and quotes from stakeholders, enabling them to express their own views on our sustainability performance. I 2-29 I 3-1 I 3-2 I

The report has been prepared in accordance with GRI Standards. 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.

We also disclose how and to what extent our economic activities are associated with environmentally sustainable economic activities, as defined in the new EU Taxonomy Regulation (see EU Taxonomy).

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