ORANO // Annual Activity Report 2024

SUSTAINABILITY STATEMENT

Societal and environmental challenges at the heart of the strategy

150 stakeholders involved in the double materiality analysis In 2024, Orano updated its analysis in accordance with the principles of double materiality provided for by ESRS 2. The group has placed listening to stakeholders at the heart of its approach. It interviewed 150 stakeholders around its various locations in order to obtain their views on how Orano’s activities or its value chain were likely to impact them.

These interviews made it possible to collect 1,100 verbatim transcripts analyzed and used to identify and rate the IROs as presented in Section 4.1.5.2. They also fed into the group’s discussions on the renewal of its ESG objectives for 2030, validated by the Board of Directors on December 16, 2024, which are presented in Chapter 1 of this report, as well as in the dedicated sections of this Chapter (climate, biodiversity, etc. ).
