session dedicated to climate change adaptation, during which experts or other manufacturers are invited to present their work or testimonials. In 2024, the group implemented numerous actions as part of the climate change adaptation program. The actions carried out during the year under the various projects include, but are not limited to the following dimensions: ● management of a test to estimate the costs associated with inaction in terms of adaptation based on a dedicated questionnaire and a fi eld audit on one of our industrial sites (July 2024); ● update of local climate projections, and use of models available via the DRIAS (1) for the main French sites (Malvési, la Hague, Tricastin and MELOX sites), for the two scenarios selected (RCP 4.5. and 8.5.) and up to 2100; ● update of the adaptation plan for the various operational entities and fi rst test of cooling vests on the operational site (summer 2024); ● organization of a dedicated conference on the Tricastin site (October 2024) and organization of the annual Methodology Committee dedicated to climate change (September 2024). Climate change adaptation targets and outcomes In the Commitment roadmap for 2030, the group is targeting 100% of industrial operations with a climate change adaptation plan. This objective takes into account the expectations of stakeholders. Its effectiveness is measured by the formalization of adaptation plans by the operating entities. At the end of 2024, all operational entities worked on the formalization of their adaptation plan. 4.2.1.6 Financial impacts of climate change Orano is working to quantify the fi nancial effects of physical and transition risks. The group plans to publish it within three years, in accordance with the phase-in provisions provided for by the standard. 4.2.1.7 Application of European Taxonomy to the activities of the Orano group Background The European Regulation 2020/852 on the European Green Taxonomy aims to direct capital flows towards environmentally sustainable investments, without prejudice to social minimums. This de fi nes the criteria for assessing the sustainability of economic activities. An activity is considered eligible for the Taxonomy if it is included in the list of activities described in the regulations, meeting one or more of the following six environmental objectives: ● climate change mitigation; ● adaptation to climate change;

GHG removals and GHG mitigation projects fi nanced through carbon credits Orano has not purchased or fi nanced carbon credits to date. The contribution of the group’s competencies to CO 2 capture is one of the initiatives carried out by the Innovation Department (see Section 4.2.5.2 for more details). The group invested in Team for the Planet at the end of 2022. As such, in 2024 it was awarded tCO 2 e in Climate Dividends by the Dividends Climat association for the year 2023. Internal carbon price An internal carbon price was introduced in 2021 in the assessment of investments. The last assessment was 85 euros/tCO 2 e avoided. Climate change adaptation policy and actions The HSE policy for 2024-2026 via its “priority 2: building a sustainable future” provides for the implementation of climate adaptation plans at the level of the entities, the revision of the continuity plans of our activities and the integration of climate projections in the basic data of our projects. In 2024, the group de fi ned the content of its climate change adaptation program called DARWIN. This was presented and approved by the Executive Committee. The monitoring of the HSE policy is the responsibility of the Health – Safety – Environment (HSE) Director, member of the Executive Committee. The climate change adaptation program is structured around four areas of work: ● Structuring of reflection: identi fi cation of the various topics to be addressed, and prioritization of the issues according to three areas (industrial facilities, natural environment and socio economic environment); ● Anticipation of consequences: know and describe the climate futures at the scale of our sites, and integrate them into the basic data of our projects; ● Adaptation of current facilities and activities: have adaptation plans adequate and proportionate to our sites and activities; and ● Resilience and awareness-raising: mobilize our collective ability to tackle the issue, and improve our resilience. Climate change adaptation actions A multi-year work program, DARWIN aims to be the common thread of the actions carried out in each of the group’s entities. It mobilizes and federates initiatives on this subject, and shares knowledge and experience between group entities. It is supported by the group’s HSE Department, and relies on the Orano Methodology Committee (COMET) through an annual 4.2.1.5 Anticipating and adapting to climate change
