4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

The anticipated effects on Groupe ADP have been identified: u questioning of its authorisations to operate water pollution control systems (or substantial changes to discharge conditions) leading to disruption of airport operations (including temporary stoppages of operations); u significant costs linked to potential clean-up operations; u situations of non-operability of certain facilities or specific assets, which could lead to specific shutdowns of operations at these specific facilities; u legal challenges; u impacts on the environment and natural habitats downstream of discharge points; For Groupe ADP, emissions from airport hubs contribute to the deterioration of local air quality, in particular through their local energy production activities and direct employee travel activities (Scope 1). Indirectly (Scope 3), passenger and employee travel, aeronautical activities and all activities hosted at airports have impacts on air quality. Regarding water quality, airports impact natural environments in various ways: wastewater/industrial wastewater and rainwater discharges. Potentially impacting activities can vary in nature: u industrial activities (maintenance, servicing, supplies, etc.); u services (catering, fuel distribution, vehicle hire, surface cleaning, sanitary facilities, etc.); 4.2.2.1 Limiting our impact on air quality Groupe ADP's hubs are committed to measuring and monitoring air quality in order to protect the health of local residents. In addition, the actions undertaken by Groupe ADP to decarbonise its Scope 1 also reduce pollutant emissions (see section 4.2.1.2. Climate change mitigation and 4.2.1.3 Development of new energy sources). The risks identified in the Vigilance Plan mirror the requirements of the CSRD. The matters relating to the Vigilance Plan should therefore be considered in the responses to the DP/DRs set out below. A description of the risk (within the meaning of the Vigilance Plan and not specifically required by the CRSD under the same heading) is specifically presented below. Description of the "air pollution" risk as defined in the Vigilance Plan Air quality in an economic area like Paris has complex dimensions and dynamics, of which air traffic is one source. According to the WHO, global air pollution is the main environmental risk to human health. Exposure to outdoor air pollution leads to the deaths of around 4.2 million people worldwide every year, according to the French Ministry of Health. u disruption of local activities; u reputational consequences.

u hotels; u winter services in the regions concerned.

Groupe ADP pays close attention to this matter on a daily basis, and dedicates substantial financing to improving the treatment of water prior to discharge or to addressing

pollution at the sites concerned. “Limiting soil pollution” topic

With regard to soil pollution, Groupe ADP does not hold any authorisations to release pollutant substances into the ground. Groupe ADP does not make any regular discharges into the ground. It is therefore not possible to establish a pollutant discharge assessment. On this basis, the IRO analysis of this matter was deemed non-material. However, airports are industrial hubs, and in the event of an incident or failure to comply with safety regulations, spills can occur on a one-off or widespread basis. In this case, there is a risk of soil and groundwater pollution that could spread to targets such as protected natural environments or drinking water wells. However, while considered non material, Groupe ADP does not shy away from this matter, and it is included in the Vigilance Plan in section 4.2.2.3 Limiting pollution of soil and groundwater – linked to the Vigilance Plan. With regard to microplastics, Groupe ADP neither produces nor uses microplastics for its processes (to date and the Groupe ADP’s current knowledge). This matter has therefore not been retained and no information is to be disclosed on this matter. With regard to substances of concern, none of the facilities managed by Groupe ADP, due to the nature of its activities, are deemed to release substances of concern or very high concern (see E2-5 — Focus on substances of concern and E2-5 — Focus on substances of concern). The risks associated with air pollution are therefore physical (human health) and economic (financial impact of air quality such as health costs, loss of productivity, etc.). For Groupe ADP, emissions of pollutants on airport hubs contribute to the deterioration of local air quality (ambient air). This deterioration increases the risk of pollution peaks, leading to additional health risks for local residents and operational restrictions for the airport. E2-1 – Groupe ADP policy for managing and mitigating air pollution [E2-1-15-(a)] → Disclosure of whether and how the policy addresses mitigating negative impacts related to pollution of air, water and soil In order to mitigate the negative impacts identified with regard to ambient air quality, Groupe ADP's general policy is to work with local authorities to put in place an appropriate regulatory and standards framework. This is detailed in section [E2-1-14] → Policies in place to manage material impacts, risks and opportunities related to pollution [see ESRS 2 MDR-P].
