Orano - Annual Activity Report 2025 155 SUSTAINABILITY STATEMENT 4 Environmental information Description of decarbonization levers Each year, the group carries out a comprehensive analysis of its scope 1, 2 location-based and market-based emissions, projected until 2030. This exercise makes it possible to explain the planned increases related to the activity or new projects, the locked-in emissions and the decarbonization levers. SUMMARY OF DECARBONIZATION LEVERS Decarbonization levers Examples of actions Reduction at end-2025 vs. 2019 Remaining actions in the transition plan CapEx spent in 2025 (in millions of euros) CapEx remaining to spend (in millions of euros) Scope 1 ● Energy efficiency ● Substitution of fossil fuels and electrification of uses ● The reduction of residual greenhouse gas emissions from processes (N2O) ● Reduction of voltage on equipment, change of lighting or motorization, etc. ● Replacement of fuel oil boilers, electrification of the Company vehicle fleet, etc. 32 ktCO2e i.e. -18% 55 ktCO2e 6.2 32 Scope 2 ● Decarbonization of electricity in countries with a high emission factor (Kazakhstan, Canada), directly or through project financing ● Financing of photovoltaic projects through the purchase of renewable energy certificates (REC) 125 ktCO2e i.e. -62% 22 ktCO2e Upstream scope 3 ● Mobilization of the main suppliers on a common approach to reducing their impact as part of their activities on behalf of the group ● Soliciting low-carbon alternatives in calls for proposals ● Eco-design of future investments ● Supplier survey including carbon intensities, decarbonization targets, and action levers ● Annual meeting with the most emitting suppliers ● Integration of the decarbonization criterion in the selection of proposals from tenders ● Broadening expectations for low-carbon or eco-designed offers ● The study of “low-carbon” calls for proposals for the civil engineering of a project No quantified data 1.5 7 TOTAL 157 ktCO2e i.e. -41% 75 ktCO2e €8 M €38 M Due to the efforts already made to reduce process-related emissions, 70% of the group’s scopes 1 and 2 emissions are directly related to the energy consumed (fossil and electric). The impact is particularly strong in mining activities, with consumption of fossil fuels and electricity with high emission factors. As such, the renewal of mining capacities is the main challenge for the group in terms of scopes 1 and 2 decarbonization. This analysis made it possible to set the following four priorities for existing operations and future projects: ● energy efficiency; ● the substitution of fossil fuels and the electrification of uses; ● the decarbonization of electricity in countries with high emission factors (Kazakhstan, Canada), directly or through project financing (purchases of Renewable Energy Certificates, REC); and ● the reduction of residual greenhouse gas emissions from processes (N2O). Orano has been analyzing its scope 3 emissions since the reference year 2019 in order to identify the action levers needed to reduce them. Scope 3 represents more than 86% of the group’s total GHG emissions in 2025. 69% of the group’s emissions were located at the front end of its activities, including in particular 60% in the items “Purchases of goods and services” and “Capital goods”. To date, around 50% of emissions are calculated using monetary data and related emission factors, which is an uncertain measurement. The group deploys its actions to reduce scope 3 in three areas: ● making progress in measuring scope 3 emissions, in particular by accurately identifying the emission factors of the group’s suppliers and increasing the proportion of the assessment calculated using physical data beyond 50%; ● carrying out jointly with the main suppliers a joint approach to reduce their impact in the context of their activities on behalf of the group; and ● pursuing eco-design actions: the Supply Chain teams participate fully in the group’s eco-design program in order to fully involve suppliers and eco-designed procurement.
