In 2025, 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: ● continuing the iterative work of estimating the costs associated with climate adaptation: ● the identifi cation and consolidation of planned investments over the next 10 years for the group’s sites, ● estimating the costs associated with inaction on adaptation, based on the methodology tested at one of our industrial sites in 2024 and extended in 2025 to the group’s other major sites; ● 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; ● updating the adaptation plan for the various industrial operations, continuing measures to adapt to working in high temperatures (testing cooling vests, shifting work schedules, implementing the heatwave decree, etc.), and validating the positive feedback on white roofs on industrial buildings (Orano Melox); (1) DRIAS is a service hosted by Météo-France that disseminates regionalized French climate projections produced by modeling laboratories. ● 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. An approach dedicated to the adaptation of industrial operations 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 also provides a methodological framework for the entities concerned and a control and consolidation organization by the group. It mobilizes and federates initiatives on this subject, and shares knowledge and experience between group entities. The group expects an adaptation plan to contain quantified, planned, and managed actions that respond to a vulnerability analysis based at least on the RCP 4.5 scenario for 2050. It must also be validated by a member of the entity’s management committee.
