SUSTAINABILITY STATEMENT Environmental information

The Orano group’s scope 3 order of magnitude is around 2 million tCO 2 e. Emissions were up compared to 2023 due to increases in activity at our main industrial sites, reflected in all items (“Fuel and-energy-related activities”, “Purchases of goods and services”, “Capital goods” and “Upstream goods transportation”). The launch of the Georges Besse II extension explains most of the increase between 2023 and 2024. As these are not yet linked to revenue growth, the scope 3 intensity is up in 2024 after several years of decline.

The reduction of the scopes 1 and 2 footprint has continued to reach -30% location-based since 2019 and -40% market-based since 2019. These reductions are in line with the group’s objectives. These results are mainly related to the decline in activity at the Somaïr mine (1) (for 28 tCO 2 e vs . 2023), as well as a program to fi nance photovoltaic projects in Kazakhstan and Canada (for 43 tCO 2 e vs. 2023). The Katco site (Kazakhstan) also increased its scope 1 related to the development of a new deposit (for 16 ktCO 2 e vs. 2023). The intensity of scopes 1 and 2 market-based GHG emissions has decreased by 53% since 2019.

n/a: not applicable, n/o: not obtainable. Methodological precision: This table presents greenhouse gas emissions calculated on a historical basis on the basis of operational control. The emissions of the Niger subsidiaries (Somaïr, Cominak, Imouraren) were included until November 30, 2024. Cominak’s data have been estimated based on 2023 results. To date, the group has no operational control over subsidiaries accounted for by the equity method.

(1) The group recognized the loss of operational control over its subsidiaries in Niger in December 2024. For more information on the situation in Niger, see Section 2.1.1.1.
