4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

[E2-1-AR 12] → Information on contextual information on the relations between its policies implemented and how they may contribute to the EU Action Plan “Towards a Zero Pollution for Air, Water and Soil” The actions presented above in chapter [E2-1-15-(c)] → Disclosure of whether and how the policy addresses avoiding incidents and emergency situations, and if and when they occur, controlling and limiting their impact on people and the environment therefore enable Groupe ADP to implement localised policies and action plans aimed at improving or maintaining the good ecological status of the natural environments on, near or downstream of the sites operated by the Group. All internal policies are designed to be in line with European policies, in particular the EU Action Plan “Towards a Zero Pollution for Water”. The principles of the Group's ISO certifications thus enable continuous improvement and updating of ISO 14001 procedures for the hubs mentioned above (see [E2-1-15-(c)] → Disclosure on whether and how the policy addresses avoiding incidents and emergency situations, and if and when they occur, controlling and limiting their impact on people and the environment) and practices based in particular on ongoing regulatory and technical monitoring. [E2-1-14] → Policies in place to manage material impacts, risks and opportunities related to pollution [see ESRS 2 MDR-P] In terms of the preservation of water resources and their sustainable management, climate change forces us to question our future capacities to meet the water supply needs of the hubs. In 2023, Groupe ADP defined its energy savings plan in which actions to reduce water consumption are described as well as actions to prevent and improve the quality of discharges (see [E2-1-15-(c)] → Information indicating whether and how the policy aims to avoid incidents and emergency situations, and if and when they occur, to control and limit their impact on people and the environment). Like its host regions, Groupe ADP requires abundant water to ensure the smooth running of its activities, but also water of very high quality (in particular for its aircraft refuelling activities), to ensure the smooth running of its catering activities at airports and elsewhere, and to ensure the good hygiene of the infrastructures entrusted to it (cleaning of surfaces, sanitary facilities, drinking water, medical points and emergency services, etc.). In this way, the Group's airports can be opportunities for local communities in a number of ways: either by helping to maintain a minimum low-water level downstream of the facilities with good water quality, as at Paris-Charles de Gaulle, or by improving the local water supply infrastructure by supporting and financing part of the necessary work, as at Amman.

E2-2 — Current and future action plans to implement policy and achieve objectives [E2-2-18] → Actions and resources related to pollution [see ESRS 2 – MDR-A] Groupe ADP maintains a regular level of investment and organisational action to ensure that its water treatment systems remain in operational condition and that its authorisations to operate them are maintained, which ultimately leads to the airport's operability. This involves, for example, investment in collection, treatment and return systems. For example, two years ago, Paris-Charles de Gaulle airport invested in a pipeline several kilometres long, enabling it to discharge directly into the Marne, a larger river than the Réneuse, where 100% of the water was previously discharged. This investment of several million euros will eventually ensure a higher discharge rate while complying with the quality thresholds applicable to it, and therefore secure its systems and operating conditions (in particular to reduce the risk of overflow from the Renardières dam enclosing the airport's rainwater collection basin). The discharge into the Réneuse will not be completely eliminated so as not to affect the river's low-water flow, but this change in discharge will reduce the risk of flooding in this catchment area. Groupe ADP has also implemented a water savings plan for its Paris airports. The aim of this plan, which is in line with the Group's inclusive vision of water policy, is to ensure that the areas hosting the Paris airports have access to sufficient quantities of good quality water. The sections on reducing consumption, returning water to nature, replacing mains water with recycled water and raising awareness are particularly developed in the section on the dedicated Vigilance Plan (see section 4.2.2.3.2 Actions for risk mitigation and prevention). This savings plan therefore includes a water quality section, detailed below, which serves as a reference for airports in drawing up their roadmap for improving the quality of water discharged into the natural environment. These actions are based on continuous measurement that adapts to changes in regulatory monitoring requirements (MISE, RSDE, ICPE, etc.). To do this, the Paris airports have continuous and spot measurement tools and sampling infrastructures (buffers, measurement stations) to provide reliable and representative measurements at all times. These components enable live remote control of the installations. This "water control tower" (particularly at Paris Charles de Gaulle) ensures that water flows are directed according to their quality, guaranteeing appropriate treatment and compliance with the thresholds imposed before discharge. In addition, the policy of combating hazardous chemicals (phyto-sanitary products, PFAS, etc.) is designed to reduce the risk of pollution and improve water quality. In addition, the airports involved in de-icing operations are continuing to adapt their facilities to ensure maximum reduction in rainwater pollution. For example, at Paris Le Bourget, the deployment of aircraft de-icing stations will make it possible to collect the water most contaminated with winter de-icing agents, ensuring that it is recovered, pumped and disposed of in an approved treatment centre rather than being discharged into the rainwater networks.
