SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

[E2-1-15-(b)] → Disclosure of whether and how the policy addresses substituting and minimising the use of substances of concern, and phasing out substances of very high concern Groupe ADP applies the principle of best available techniques in order to constantly improve not only its operating processes, but also the nature of the products used in its operations. For example, Paris-Orly, Paris-Charles de Gaulle and Paris-Le Bourget airports no longer use any plant protection products to manage their green spaces (since 2015 for Paris-Orly, 2023 for Paris-Le Bourget and 2024 for Paris-Charles de Gaulle). For many years, Groupe ADP has been using biodegradable products to prevent ice from building up and de-ice aircraft, taxiways and runways at its Paris airports. But these biodegradable products, like the other chemicals still in use because there are no alternatives to date, need to be monitored. The controls carried out by ADP to monitor the quality of its water (particularly rainwater) comply with the regulations applicable to it (see [E2-3-AR 18] → Information on the targets set at site level (pollution)) and enable permanent or regular monitoring of potentially polluting substances, the results of which are made public. Further information on substances of concern can be found in the dedicated section: E2-5 — Focus on substances of concern [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 Groupe ADP's airports have been committed to environmental quality for many years, irrespective of their geographical location. As mentioned above, the environmental risks of pollution linked to aviation activities have, since the 1990s, led to an increased awareness of the risks of pollution and therefore a need to control (mitigate and manage) these risks. This is why a large number of airports in the ADP network are now ISO 14001 certified. Below is the list of hubs ISO 14001 certified in 2024: u Saudi Arabia – Prince Mohammad Bin Abdulaziz Medina; u France – Paris-Charles de Gaulle; u France – Paris-Orly; u France – Paris-Le Bourget; u Georgia – Alexander Kartveli Batumi; u Georgia – Shota Rustaveli Tbilisi; u Jordan – Queen Alia Amman; u Kazakhstan – Almaty; u Northern Macedonia – Skopje; u Northern Macedonia – Ohrid St. Paul the Apostle; u Tunisia – Enfidha-Hammamet; u Tunisia – Monastir Habib-Bourguiba; u Turkey – Milas-Bodrum; u Turkey – Antalya. As part of these certifications, the hubs have set up processes for preventing and responding to polluting events such as accidental oil spills on aeronautical areas, leaks from tanks or overhead or underground piping, etc. Internal crisis management processes and policies for the prevention and repair/remediation of polluting events and so-called Polluted Sites and Soils incidents are implemented where necessary in compliance with local law (and in particular, in France, environmental regulations based on water law, waste

regulations and the National Methodology for Polluted Sites and Soils). The aim of these policies is to prevent incidents and the associated risks, such as seepage into the soil and groundwater (see section 4.2.2.3. Limiting pollution of soil and groundwater), in water networks (particularly rainwater) and into surface water. In the event of incidents/accidents, physical interventions are carried out on the networks (depending on the configuration and degree of urgency), such as plugging the networks, isolating the pollution in dedicated tanks, pumping and sending the pumped products for treatment/destruction in dedicated, approved facilities, setting up floating booms, stopping discharges into the natural environment (by physical action on valves), etc. Buffering actions can also be taken (by retaining volumes in order to regulate the passage of water through the treatment plants so that discharge continues to comply). At certain facilities, in order to preserve the integrity of the infrastructure (which could pose problems for the safety of people and property in the event of a failure), the decision may be made (in accordance with the regulations which provide for this situation) to overflow the treatment systems and discharge non-compliant waste. In addition, with the exception of Almaty airport (TAV – Kazakhstan), Groupe ADP does not directly handle and distribute aviation fuels (these are either outside its scope of operations or completely delegated to independent operators). The airfield manual brings together the safety elements relating to the operation of aeronautical areas. The risk of a hydrocarbon spill is described as an accident risk for floor operators (slips, sanitary facilities) and for aviation safety (fire risks in particular). Incident and near miss notification systems and procedures are also implemented on the sites in compliance with aviation safety regulations. Lastly, the work carried out by Groupe ADP over the last few years, particularly in Paris, has made it possible to capture and process information on the chemical products used in the company. To date, based on these databases, we do not use any substances of concern in our airport processes. This approach makes it possible to limit the risk of incidents linked to these substances by removing them from the activities carried out by Groupe ADP. See [E2-3-23-(d)] → Disclosure of whether and how the target relates to the prevention and control of substances of concern and substances of very high concern. We should add here that in 2023 Groupe ADP's Executive Committee adopted a water savings plan for its Paris hubs. This included actions to reduce consumption, to reduce the consumption of drinking water (by substituting rainwater for certain uses), actions to restore water (by studying and implementing a policy to limit the sealing of airport grounds) and also actions to improve the quality of water discharged. For ADP, it is important to reduce water consumption while at the same time preserving the quality of the resource. These various actions, adapted to the Paris airport sites, covered simple, short-term actions ( e.g., maintaining and modernising the means of continuously measuring our discharges into rivers (see [E2-4-30-(b)] → Description of measurement methodologies used (air, water and soil pollution)), more complex or costly actions to be implemented in the medium and long term ( e.g., stopping the use of plant protection products in the Paris airports (see [E2-1-15-(b)] → Disclosure of whether and how the policy addresses substituting and minimising the use of substances of concern, and phasing out substances of very high concern) and improving our contractual arrangements with our tenant customers and implementing discharge agreements with ADP SA networks).
