Orano - Annual Activity Report 2024 113 SUSTAINABILITY STATEMENT 4 Societal and environmental challenges at the heart of the strategy Changes in preparation or presentation of sustainability information The presentation of the sustainability statement was aligned for this first exercise with the requirements of ESRS 1. Some information required by ESRS is presented for the first time. Reporting errors in prior periods During the current campaign, the errors identified in the reports of previous years are corrected.
