SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

[E1-ESRS 2 IRO-1-AR 11-(d)] → The identification of climate-related hazards and the assessment of exposure and sensitivity are based on climate scenarios with high emissions The assessment takes into account two IPCC global warming scenarios, with 2030 and 2050 horizons: u SSP2-4.5 ("median" scenario, leading to an average global warming of 1.6 to 2.5°C by the middle of the century and a warming of 2.1 to 3.5°C at the end of the century); u SSP5-8.5 (most pessimistic, unrealistic scenario, leading to a global average warming of 1.9 to 3°C by the middle of the century and a warming of 3.3 to 5.7°C at the end of the century). It should be noted that in the medium term (horizon 2030), the results obtained for SSP5-8.5 and SSP2-4.5 do not differ significantly, which is mainly due to the fact that the climate projections described in these two scenarios diverge from 2030. In the long term, the most unfavourable scenario, SSP5-8.5, is used for analysis in order to prepare the Group for a high-emission climate scenario and an exhaustive resilience analysis. [E1-ESRS 2 IRO-1-21] → Explanation of how the climate - related scenarios analysis has been used for the identification and assessment of physical risks in the short, medium and long term The various climate hazards – in the IPCC's SSP 2-4.5 and SSP 5-8.5 scenarios – have been characterised for the 2030 and 2050 horizons by indicators whose measurement at these horizons has been assessed using scientific climate models (examples of models used for the indicators relating to the heat wave hazard: MRI-ESM2-0, MPI-ESM1-2-LR, MIROC6, IPSL-CM6A-LR). The impact of these hazards was then assessed using the methodology described above. PROCESS FOR ANALYSING CLIMATE TRANSITION RISKS AND OPPORTUNITIES [E1-ESRS 2 IRO-1-20-(c)] → Process to identify climate - related transition risks and opportunities The new airport model – at the heart of the 2025 Pioneers strategy and business model – has, since 2022, already taken into account the risks and opportunities of climate-related transition with the goal of transforming the Group's business model. In fact, two of the airport's transformation axes, into a multimodal hub on the one hand and an energy hub on the other, are responses to: u the need to combat the risk of global warming – which can be broken down into regulatory risks (limiting the development of aviation), market risks (changes in customer consumption patterns), reputational risks (societal expectations that are higher than the actual scope of the action), etc.; u the associated opportunity to create value. In 2023, Groupe ADP decided to supplement this approach with a more detailed analysis. To this end, in parallel with the study of physical risks, Groupe ADP has identified and prioritised the risks and opportunities of the transition of its activities to a low-carbon economy in order to better identify how climate-related changes may impact activities, financial results and long-term sustainability.

u for water-related hazards: u surface water flooding RP 100 (in m): depth of flooding due to surface water for a return period of 100 years, u water stress (in %): ratio between water demand and supply; u for wind and ground hazards: u seismic risk index: earthquake risk classified from 0 to 8 on a logarithmic scale, u tropical cyclone – wind gust RP 100 (in m/s): tropical cyclones, maximum wind speed for a return period of 100 years. [E1-ESRS 2 IRO-1-AR 11-(b)] → Short, medium and long term time horizons have been defined See [E1-ESRS 2 IRO-1-AR 11-(a)] → Climate-related risks have been identified in the short-, medium- and long-term. [E1-ESRS 2 IRO-1-AR 11-(c)] → Identifying the exposure and sensitivity of assets, economic activities and the supply chain to climate-related hazards Groupe ADP has assessed the extent to which its airport hubs and their economic activities could be exposed to physical climate risks by carrying out a review and rating. Both gross and net physical risks are rated using a combination of three criteria: u the hazard: climate-related event ( e.g. , extreme heat, drought, flooding, etc.), characterised by the indicators specified above; u exposure: location, physical attributes and value of assets (depending on their location and physical attributes) or number of people who could be affected by a hazard; u vulnerability: propensity or predisposition to be adversely affected by a certain risk, sensitivity to damage, etc. It is on this criterion that the implementation of adaptation measures has an impact. Lastly, as regards the supply chain, the study on the dependence and impacts on stressed natural resources conducted in 2022 made it possible to identify the impacts and, especially, the dependencies and risk factors of Groupe ADP vis-à-vis the resources used in its construction projects, operations and supply chain (see “A responsible and sustainable business model” in the general introduction to this document). The risks studied highlighted several significant factors related to the availability of raw materials for the successful development of hubs and their ecological transition. On this basis, Paris Aéroport has published its energy and materials (water) sobriety plans and has embarked on a circular economy approach (operating and construction waste, with application of circular economy principles, including reuse and recycling). Aéroports de Paris SA is a signatory of the “Metropolitan Charter for circular construction” launched by the Métropole du Grand Paris.
