Orano - Annual Activity Report 2025 151 SUSTAINABILITY STATEMENT 4 Environmental information Assumptions underlying the analysis Transition risks are based on the STEPS and CPS scenarios of the IEA Outlook 2025, as well as on internal forward-looking scenarios. Physical risks are assessed taking into account the relevant hazards of AR 11 of ESRS E1. They were analyzed on the basis of the RCP-4.5 and RCP-8.5 emission scenarios, up to 2050 and beyond, consistent with the industrial strategy. HAZARDS TAKEN INTO ACCOUNT IN THE PHYSICAL RISK ANALYSIS Hazards taken into account in the physical risk analysis Temperature-related hazards Wind-related hazards Water-related hazards Solid mass-related hazards Chronic ● Changing temperature (air, freshwater, marine water) ● Heat stress ● Temperature variability ● Changing wind patterns ● Changing precipitation patterns and types (rain, hail, snow/ice) ● Precipitation or hydrological variability ● Saline intrusion ● Sea level rise ● Water stress ● Coastal erosion ● Soil erosion ● Solifluction Acute ● Heatwave and extreme heat wave ● Cold wave/frost ● Wildfire ● Cyclones, hurricanes, typhoons ● Storms (including blizzards, dust, and sandstorms) ● Tornado ● Drought ● Heavy precipitation (rain, hail, snow/ice) ● Flood (coastal, fluvial, pluvial, ground water) ● Marine submersion ● Marine heat waves ● Landslide ● Subsidence related to Clay shrinkage and swelling (RGA) Hazards not relevant to Orano’s operations ● Permafrost thawing ● Ocean acidification ● Glacial lake outburst ● Avalanche ● Soil degradation 4.2.1.4 A continuous and renewed effort on our carbon footprint Aware of the climate change mitigation issue, the nuclear industry regularly conducts studies of its greenhouse gas emissions over the entire life cycle. Emissions associated with the fuel cycle are the largest carbon impact item. The decarbonization of the cycle’s activities is thus a major issue in terms of compatibility with the Paris Agreement and setting an example. In addition to being convinced that nuclear power can play an essential role in the energy transition towards low-carbon electricity, Orano has been involved in a program to reduce its own emissions since 2004 in order to contribute to the global issue of carbon neutrality. Group’s transition plan for climate change mitigation This transition plan is presented annually to the Board of directors as part of the presentation of the group’s strategy and financial trajectory. Regarding the group’s scopes 1 and 2 emissions, market-based scopes 1 and 2 emissions were reduced by 66% between 2004 and 2019. At the end of 2024, the group renewed its target of a 25% reduction in 2030 vs. 2019. This objective has been achieved to date, but the group is vigilant as it increases its activities. With regard to scope 3 emissions, which the group has been studying since 2020 and which represent 86% of the group’s total emissions, mainly upstream of the group’s own activities, the group has set itself a medium-term target. It aims for its 80 most emissive suppliers, representing 50% of “purchases of goods and services” and “non-current assets” emissions, to be included in a decarbonization trajectory The group’s objectives will ultimately contribute to the reduction in emissions per kWh of nuclear origin (between 4g CO2/kWh according to EDF life cycle analysis and 12g CO2/kWh in the IPCC literature).
