In 2023, Orano introduced a market-based scope 2 setting the group’s reduction targets. The group includes in its scope 1 the emissions associated with the change in land use (called emissions from biomass (soils and forests)), in accordance with the ADEME v5 methodology of July 2022. The gases taken into account are as follows: CO2, CH4, N2O, and halogen compounds (CFC, HCFC, HFC, PFC, SF6, NF3). The GWPs used are those of the IPCC AR6. All conversion and emission factors used in the consolidation are reviewed each year and updated when significant changes are observed. Data from Niger subsidiaries were included until November 30, 2024. Activity data for the Cominak subsidiary were estimated on the basis of 2023 data. The energy data presented in the table excludes joint operations operated by Cameco consistent with the emissions presented. Scope 1: • The databases used are: the ADEME carbon database v23 (France), fuel emission factors provided by CITEPA. • The GWP of the refrigerants used by Orano are those supplied by the AR6. When the data is not obtainable, they are calculated on the basis of the Safety Data Sheets provided by the suppliers. Scope 2: • The databases used are: ADEME carbon database v23 (France), “IEA Emissions Factors” 2024 database, National Inventory Report Greenhouse Gas Sources and Sinks in Canada: 1990-2017. Environment Canada. Online: https://unfccc.int/documents/194925. • The values for the year are estimated using the emission factor of the previous year (factor 2023 for the year 2024). Emissions from the previous year are updated on the basis of the actual factor recorded on the network and published in the databases. Is used to calculate the “combustion” share of the average electricity mix emission factor. • For scope 2 market-based, Orano records the renewable energy certificates acquired and activated for the year. Their place of production is linked to the country of consumption (Kazakhstan, Canada).
