4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

[E2-3-24-(c)] → Disclosure of how responsibility for respecting identified ecological thresholds is allocated (pollution) With regard to the elements to be complied with described in [E2-3-24-(a)] → Disclosure of the ecological thresholds identified, and the methodology used to identify such thresholds (pollution), responsibility for compliance with the thresholds lies with the local entity of Groupe ADP which holds the corresponding authorisation or operates the installation. It should be noted that not all sites managed by Groupe ADP are responsible for all airport sites. It is not uncommon (as in Ankara, for example) for the entity in charge (TAV in the case of Ankara) not to be responsible for water discharges, as it is only responsible for operating the terminal. It is therefore necessary to refer to the local organisation to determine responsibility (often borne by a specialised public service or one of its delegates). Also by way of example, for its Paris airports, Aéroports de Paris SA is directly responsible for monitoring and ensuring compliance with water discharges pursuant to the aforementioned inter-prefectural decrees (see [E2-3-AR 18] → Information on the targets set at site level (pollution). [E2-3-22] → [E2] Tracking effectiveness of policies and actions through targets [see ESRS 2 MDR-T] Groupe ADP complies with local regulations for its water pollution targets, see [E2-3-AR 18] → Information on the targets set at site level (pollution). These monitoring and reporting obligations include, in particular, the provision of results to the relevant local water pollution authorities where required. For Paris in particular, the effectiveness of the policies and actions undertaken is monitored annually by the prefectural authorities. The results of this work and any necessary changes to control and reporting systems are included in the related prefectural decrees. It should also be noted that an annual Water Law Committee is hosted in Paris-Charles de Gaulle airport. Bringing together the prefectural authorities (the water police in particular), local authorities (municipalities, departments, water network operators, etc.) local residents' associations, and the relevant departments of Aéroports de Paris SA, it provides an opportunity for an open exchange to collect and answer questions on the basis of scientific studies carried out by Aéroports de Paris SA, its tenants and the authorities. It draws up an annual assessment of the effectiveness of the treatments implemented before the water is discharged and may give rise to changes in the allocation of measurement, management and resource allocation strategies (see [E2-3-24-(a)] → Disclosure of the ecological thresholds identified, and the methodology used to identify such thresholds (pollution)). In Paris, the close, ongoing exchange of information between our laboratory department and the operating departments of the Paris airports helps to improve practices at all levels: u limiting the use of products; u equipment development; u new operating methods; u joint monitoring of new treatment technologies and products. The common objective is to limit the pollution of rainwater from the airport to prevent any risk of contamination of the natural environment.

[E2-3-23-(b)] → Description of whether and how the target relates to the prevention and control of emissions to water and respective specific loads See [E2-3-24-(a)] → Disclosure of the ecological thresholds identified, and the methodology used to identify such thresholds (pollution). [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 Information on this point is presented in section E2-5 – Focus on substances of concern. [E2-3-24] → The ecological thresholds and entity specific allocations taken into consideration when setting pollution-related targets See [E2-3-24-(a)] → Disclosure of the ecological thresholds identified, and the methodology used to identify such thresholds (pollution). E2-4 – Evaluation (method and results) of levels of pollutant discharges/emissions by Groupe ADP (including projections) The information presented below corresponds to the pollutant flows measured and available at the time this report was written, i.e., the estimated flows for 2024 at Groupe ADP's Paris airports. As mentioned above, not all airports control the systems they use for discharging water into the natural environment. In addition, for this first year, it was not possible to consolidate all the necessary data by the required date. The disclosed coverage rate covers around 70% of the Group's total scope. The information disclosed corresponds to the combined results of measurements taken throughout the year using the measurement systems described here: [E2-4-30-(b)] → Description of measurement methodologies used (air, water and soil pollution) and in accordance with the regulations applicable in [E2-3-AR 18] → Information on the targets set at site level (pollution), to which the European Union RSDE regulation must be added. The pollutants disclosed are those considered applicable to the hubs presented. Any other pollutants mentioned in the regulations are not measured, as they are not considered applicable to the airports in question. Measurements for the whole of 2024 are not available at the time of writing and cannot therefore be presented. However, an estimate is proposed. This estimate is based on an extrapolation from the 2023 data to the 2024 data, based on the volume of water discharged into the natural environment at the airports in question (this data being available at the time of writing). At present, therefore, they do not take account of operating variants (such as the number of flights, for example) or variable weather conditions. At the time of writing, data on water flows (quantity and quality) from Le Bourget were not available. The extrapolation from 2023 to 2024 indicated above for Charles de Gaulle and Orly is not applicable to Le Bourget this year. Groupe ADP does not use or produce microplastics and the activities carried out by the Group are not deemed to emit microplastics. This parameter is therefore not measured.
