SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

Pollution caused by human activities is a major problem that Aéroports de Paris SA's sustainable development policies have sought to address since the 1990s. This pollution has an impact on human health and is one of the main causes of the collapse of biodiversity according to the IPBES (see ESRS E4: 4.2.3.1. Limiting pressure applied on biodiversity). This is why it's essential to take this matter into account to ensure sustainable economic development. Pollution IRO analysis E2.IRO-1 — Presentation of IROs related to air and water pollution [E2-ESRS 2 IRO-1-11-(a)] → Information on the methodologies, assumptions and tools used to select sites and activities to identify pollution-related impacts, risks and opportunities in upstream and downstream operations and the value chain As indicated in section IRO-1, Groupe ADP carried out a double materiality assessment based on the methodology described above in IRO-1 — IRO analysis methodology and integration into Groupe ADP's overall risk management process. This analysis focused on the impacts, risks and opportunities related to air, water and soil pollution. The analysis used to select the sites and the methodologies used to identify the impacts, risks and opportunities are described in section [2-SBM-3-48-(a)] → Description of the material impacts resulting from the materiality assessment The main sites identified as having a potential impact on water and air quality in 2024 are the Group's financially consolidated airports, and in particular the facilities they host for energy production and mobility in terms of air pollution, and the facilities discharging rainwater and/or wastewater in terms of water pollution. [E2-ESRS 2 IRO-1-11-(b)] → Information on whether and how consultations were conducted (pollution) As indicated in chapter IRO-1 — IRO analysis methodology and integration into Groupe ADP's overall risk management process, consultations and interviews with stakeholders concerned by air pollution, water pollution and soil pollution were carried out in 2023 and 2024. The results have been used to enrich the Group's governance. The Group's double materiality assessment has therefore been extended to the usual scope of the Group's financial reporting. [E2-ESRS 2 IRO-1-AR 9] → Disclosure of the outcome of the materiality assessment (pollution) Groupe ADP has identified pollution matters (water pollution, air pollution) as material to its activities.

Groupe ADP operates facilities that can pollute air and water in France and abroad, which means that pollution management is a material topic for the Group. As a result, the Group complies with regulatory requirements and constantly updates its industrial operating facilities, such as power generation plants, distribution and collection networks, and water treatment centres before discharging water into the natural environment. “Limiting our impact on air quality” topic As airport operations are a source of atmospheric pollutant emissions, Groupe ADP has identified "limiting the impact on air quality" as a material topic for its activities. More directly, airport activity is itself responsible for pollution linked to the production of part of the energy needed to operate the airport's equipment and infrastructure, to move employees around and to carry out flight operations on the ground. Ambient air pollution from airport activities can have a negative impact on: u people living around airports; u airport customers and staff; u the natural environment. These consequences can be health-related, economic, legal and environmental. Groupe ADP is aware of the effects of air pollution and has been taking concrete action for years to anticipate/prevent, control and reduce the risks. Groupe ADP pays close attention to this matter on a daily basis, and dedicates substantial financing to improving the treatment of its atmospheric emissions. This proactive approach is reflected in the transition to energy sobriety and the implementation of its decarbonisation trajectory. The reduced use of petroleum hydrocarbons in the future will result in a significant reduction in air pollution from activities that have an impact on air quality. Groupe ADP has thereby implemented an ambitious policy to reduce the emissions of atmospheric pollutants linked to its activities and facilities, and those of its stakeholders in the airport community. “Controlling water pollution” topic Airport activity is known to be responsible for pollutant discharges into water downstream of airports, which could degrade aquatic environments and therefore need to be controlled. Uncontrolled pollution could have a lasting impact on water u the economic fabric of the airport (tenant companies) and the surrounding area (drinking water and industrial water use); u passenger airport customers (drinking water); u the natural environment (biodiversity). The associated risks include health-related, operational, legal and financial risks for Groupe ADP. resources (surface water and groundwater) for: u the local population (use of drinking water);
