Annual Activity Report 2025

SUSTAINABILITY STATEMENT

Environmental information

Orano has already achieved a 41% reduction in 2025 in its scopes 1 and 2 market-based emissions vs. 2019 but anticipates future increases related to the increase in its activity as part of the nuclear revival and the launch of new activities contributing to the transition (enrichment capacity increase, renewal of mining capacity, recycling of electric vehicle batteries, etc .). 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 with its suppliers the origin of emissions within the value chains and the levers for decarbonizing its largest items. Emissions generally come from

the very upstream stages of extraction or transformation (through energy consumption), which are not in the hands of the group’s direct suppliers. It is therefore expected that the decarbonization of supplies will take time. Orano therefore cannot commit to a time horizon for the reduction of its scope 3, even more so in a context of increased activities. At end-2024, the group has therefore set itself a medium-term objective, namely to engage the 80 suppliers with the highest emissions in reducing their emissions by 2030, representing 50% of scope 3 emissions from the purchase of goods and services and capital goods.
