Orano - Annual Activity Report 2025 157 SUSTAINABILITY STATEMENT 4 Environmental information At end-2025, 76% of industrial projects of more than 20 million euros followed the eco-design approach. Specific actions for the decarbonization of transport The “Logistics” items account for 7% of the group’s scope 3 emissions, including 4% for the transport of goods and 3% for business and home-work travel. Although not very significant, Orano is committed to the decarbonization of its logistics operations as a player in nuclear logistics, as a contractor and as an employer. Since 2021, the Nuclear Casks and Services Business Unit, a nuclear materials transport operator, has been offering its customers the carbon footprint of its transport services as well as low-carbon alternatives when possible. It offers customers in France and Europe an optimized, broader and more integrated range of road and rail transport services. Orano NPS is also working on extending the life of its packaging in order to reduce the need for resources and the carbon impact. The DPS2D (Decommissioning and Waste Strategic Planning Division) includes the carbon criterion in the study of the mode of transport of radioactive waste as part of the CIGEO project. Discussions are underway to extend it to the management of the group’s nuclear waste. A working group on the eco-mobility of business and home-work travel has proposed a strategy adopted by the executive committee. This approach is based on three areas: the electrification of the Orano vehicle fleet, business travel, and employee mobility. With regard to the mobility of its employees, measures have already been implemented in several group entities, such as the provision of public transport for employees of the la Hague site, and incentives for the use of public transport at its head office via more employer-paid transport passes or promotion of local carsharing applications. Estimate of locked-in emissions by 2030 Locked-in emissions represent future emissions likely to be caused by the assets or products sold by the Company. The group carried out a preliminary analysis of its locked-in emissions out to 2030, which highlighted: ● no emissions are locked within its scope 3 downstream, as these are mainly linked to the consumption of fossil fuels by the group’s electric utility customers in their activities and are taken into account in their mitigation plans; ● locked-in emissions related to the process in the absence of capture technology (N2O in France), up to 17 ktCO2e; ● locked-in emissions associated with assets (fossil fuel boilers, for example) for a total estimated at 73 ktCO2e; ● locked-in emissions associated with land-use change under the SRI method for a total estimated at 30 ktCO2e; ● locked-in emissions of 44 ktCO2eassociated with electricity and steam consumption, assuming an emission factor of 30 gCO2e/ kWh in France. All locked-in emissions by 2030 amounted to 165 ktCO2e. The greenhouse gas emissions reduction target set by the group takes these locked-in emissions into account, without abandoning existing assets. Financial amounts associated with the transition plan and link with taxonomy The planned amount of investments in the transition plan remaining to be carried out after 2025 represents approximately 38 million euros, almost all of which has been identified as eligible for the European Green Taxonomy, in accordance with the information published in Section 4.2.1.7. In 2025, the group spent 8 million euros on decarbonization projects, of which 6.8 million euros are eligible for the European Green Taxonomy. Orano does not monitor the OpEx associated with the transition plan. The group has not made any investments in coal, oil, or gas. It is not included in the “Paris Agreement” benchmarks. Gross scopes 1, 2, 3 greenhouse gas emissions and total GHG emissions Methodological information The group complies with the rules of the GHG protocol for the recognition of these greenhouse gas emissions. In the 2025 financial year, two changes are notable: ● the group uses ADEME monetary emission factors to calculate its upstream scope 3. These have been updated on an annualized basis in the v23.8 made available in October 2025. The use of these emission factors, including retroactively, resulted in a reduction in scope 3 emissions by nearly 30%; and ● in light of the loss of operational control of its Nigerien subsidiary, Somaïr, effective December 2024, and the deconsolidation of its financial statements, the group has restated its entire history to remove this subsidiary from past emissions, including those for the reference year, insofar as operations the loss of control and expropriation (1) of Orano by the State of Niger did not end mining activities. The group has retained in its history the emissions of the Cominak subsidiary, whose operational activities ceased in 2021, prior to the loss of operational control and its deconsolidation from the group.
