SUSTAINABILITY STATEMENT Environmental information

Climate change mitigation policy and actions Orano has included a “Climate” priority in its commitments and roadmap. This roadmap covers climate change mitigation and climate change adaptation, all united within a Climate strategy (see Section 4.2.1.1). Climate change mitigation aims to reduce the group’s emissions through various levers, described in Section 4.2.1.4. Monitoring of the Engagement roadmap for 2030, the HSE policy and the Climate strategy is the responsibility of the Health – Safety and Environment (HSE) Director, member of the executive

committee. It is presented to the executive committee and the Board of directors at least once a year. These documents are available on the group’s website. The group has taken into account the expectations of its stakeholders in their development, namely the expectations of its customers to contribute to the reduction of their scope 3, and of its shareholders and investors to contribute to the alignment of their portfolios with the Paris Agreement on the climate.
