ORANO // Annual Activity Report 2024

Orano - Annual Activity Report 2024 151 SUSTAINABILITY STATEMENT 4 Environmental information In 2025, the group will analyze the impact of the end of the activities of its Niger subsidiaries and the expectation of the CSRD Directive to include the emissions of its joint operations in the group’s consolidated GHG emissions, in accordance with its climate commitment. The group’s changes and its projects have a direct impact on the group’s scope 3 emissions, located in the upstream value chain under “Purchases of goods and services” and “Capital goods”. Since 2020, the group has been studying ways to decarbonize its largest items but has not set a quantitative target for reducing scope 3. The group has set itself a resource target through its Commitment roadmap for 2030, its Climate strategy and Responsible Purchasing policy. Orano plans to involve 80 suppliers with the highest emissions in reducing their emissions. ORANO DECARBONIZATION TARGETS 2019 scopes 1 and 2 market-based published historically Reduction in GHG emissions already achieved (Corminak, la Hague, etc.) 2024 scopes 1 and 2 market-based emissions Forecast increase in activity (capacity extension, renewal of mining capacities, etc.) Production effect on existing operations Decarbonization projects: leveraging energy efficiency, replacing fossil fuels and electrifying uses Decarbonization projects: indirect electricity decarbonization lever (REC) 2030 scopes 1 and 2 marketbased objective New activities (MED, batteries, etc.) Locked-in emissions 479 290 78 79 43 45 359 2 141 189 Growth in activity in Orano operations Decarbonization levers for Orano operations KtCO2e Source: Orano “1.5°” trajectory according to SBTI -25% The French National Low Carbon Strategy (SNBC v2 of 2020) expects -40% by 2030 vs. 1990, i.e., 690 ktCO2e for the group 240 ktCO2e 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 Contribution of decarbonization projects 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. 43 ktCO2e SCOPE 2 ● Decarbonization of electricity in countries with a high emission factor (Kazakhstan, Canada), directly or through project financing (REC) ● Financing of photovoltaic projects through the purchase of renewable energy certificates 45 ktCO2e 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 ● Annual meeting with the most emitting suppliers ● Methodological support ● The study of “low-carbon” calls for proposals for the civil engineering of a project No quantified data
