Methodological precision: This table presents greenhouse gas emissions calculated on a historical basis on the basis of operational control. Emissions from entities in joint operations operated by Cameco are accounted for within the group’s upstream scope 3, on the basis of the previous year (2023 data in 2024). 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.
