4.2.1.1 Climate change adaptation E1-4 — Targets for climate change adaptation [E1-4-32] → Tracking effectiveness of policies and actions through targets [see ESRS 2 MDR-T] Since 2022, Groupe ADP has been committed to structuring its actions to adapt to climate change. Methodological targets have been defined to improve the understanding and An analysis of gross physical risks has been carried out between 2022 and 2023 for all Groupe ADP assets, both in France and abroad. This analysis has enabled us to identify the most critical sites and to map the climate-related hazards that have the greatest impact on our infrastructure, our activities and our employees. Initiated in 2024, net physical risk analyses incorporating current and future climate change mitigation and adaptation measures were then undertaken for six of the Group's controlled airports: the three Paris airports, as well as the airports of Amman (Jordan), Izmir-Adnan Menderes and Milas Bodrum (Turkey, to be completed in 2025), which are the three international airports with the highest exposure in terms of gross risks. The results for these last three hubs will be available in 2025. The aim is to extend this analysis of net climate risks to all 15 airports controlled by Groupe ADP in seven countries. Application of monitoring tools and indicators to other geographical contexts As Groupe ADP has an international footprint, current studies must include the development of indicators adapted to local contexts to quantify the potential and residual impacts of climate hazards. The studies carried out in the Paris hubs, in Jordan and soon in Turkey have looked particularly closely at the risks of flooding and heat waves. The aim is to use the same methodology as for the previous studies, i.e. , gross risk analysis, net risk analysis and then residual net risk analysis, but applying it to other geographical contexts and, consequently, to other hazards that could have an impact. Structuring the adaptation process Several proofs of concept (POC) and initiatives are in progress or deployed at the Paris hubs, such as the Cana Marne project, the reinforcement and modernisation of electrical networks, the regular renovation of runway structures and the existence of a centralised command centre (APOC – Airport Operation Center). These initiatives form the basis of a global adaptation strategy. The aim is to integrate these initiatives into the adaptation plan for the three Paris hubs in 2025 and to propose complementary measures. Taking greater account of the risks associated with climate change Work is also in progress to raise team awareness and integrate climate issues into decision-making processes. A key stage in this work was the presentation of the adaptation process and its main guidelines to the Executive Committee in June 2023, underlining the importance of this issue for all Groupe ADP's activities. integration of climate issues into its activities: Continued analysis of net physical climate risks

Various working groups were then set up between the Sustainable Development Department, which is responsible for these issues, and the various operational units operating at the Paris-Charles de Gaulle, Paris-Orly and Paris Le Bourget hubs, in order to co-construct a detailed action plan and integrate climate risks into business continuity plans. The aim is to take greater account of climate risks in strategic and budgetary plans in 2025. [E1-4-33] → Disclosure of how GHG emission reduction targets and/or any other targets have been set to manage material climate-related impacts, risks and opportunities With regard to climate change adaptation, Groupe ADP has formalised structural methodological targets to lay the foundations for effective management of physical risks and transition risks. The strategy for climate change adaptation is based on reference pathways and recognised recommendations. More specifically, the physical risk assessment was carried out taking into account two of the five scenarios defined by the Intergovernmental Panel on Climate Change (IPCC): u a median scenario (SSP2-4.5) predicting average global warming of 1.6 to 2.5°C by 2050 and 2.1 to 3.5°C by 2100; u the pessimistic scenario (SSP5-8.5) anticipating average global warming of 1.9 to 3°C by 2050 and 3.3 to 5.7°C by 2100. Since then, the French government has defined a reference global warming trajectory (TRACC) to guide adaptation actions in France to cope with the effects of climate change. If this trajectory becomes a confirmed requirement of the State, Groupe ADP plans to undertake, in 2025, a gap analysis between the assumptions chosen in the initial study and the TRACC assumptions, in order to bring its work fully into line with government directives. For the study of transition risks carried out in 2023, Groupe ADP used the various scenarios established by the French Environment and Energy Management Agency (ADEME) in its reports Transition 2050 (2021) and Élaboration de scénarios de transition écologique du secteur aérien [Drafting scenarios for the ecological transition of the aviation sector] (2022). The scenarios identified and the risks analysed were then structured according to the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). Finally, an additional analysis of the costs of adaptation will also be carried out to compare the financial impacts of adaptation to the different trajectories studied. The aim of this approach will be to assess the cost of inaction in the face of climate change compared with the cost of gradual adaptation in line with so-called 'median' scenarios (SSP2-4.5 and TRACC), as well as the cost of more ambitious adaptation aimed at guaranteeing long-term resilience in the face of maximum impacts (SSP5-8.5) despite potentially higher investments. These studies will make it possible to prioritise investments and define precise targets, taking into account the costs/benefits associated with each scenario.
