4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

4.2.2.4.3. Progress approach The aforementioned measures have highlighted and strengthened the retention and monitoring systems at the main facilities deemed to be the most at risk of pollution on the Paris hubs, namely: u automotive fuel storage (third-party service stations); u third-party dry cleaning facilities; u third-party cleaning and surfacing workshops; u historical fire protection installations operated by ADP and third parties (specific PFAS risk); u third-party hazardous material transport networks (kerosene oil networks).

Aéroports de Paris SA's laboratory, information systems and site management are developing monitoring tools to improve the knowledge and traceability of information on the occupants of our sites in order to better control pollution by third parties and possibly deduce its authorship. The first version of a dedicated tool, which first went online in 2022, is now operational and, following its development, provides an effective database for researching historical pollutants and understanding the soil and groundwater beneath Paris airports.

LIMITING PRESSURE APPLIED ON BIODIVERSITY

Sustainability matter

Groupe ADP, through its development projects, airport operations and commercial activities, may generate pressure on the biodiversity present on hubs and beyond, through its value chain. Airport activities can therefore have an impact on the modification or degradation of habitats and species. Groupe ADP's responsibility and the challenges it faces in contributing to the erosion of biodiversity must be considered throughout the value chain. These risks vary depending on the sites studied. The collapse of biodiversity is causing tensions over supplies, the emergence of zoonoses and difficulties in carrying out hub development projects due to the land artificialisation they underpin and the direct and indirect impacts on ecosystems and living populations. Groupe ADP: the biodiversity policy applies to all Groupe ADP's consolidated airports, in France and abroad, as well as to the consolidated Extime subsidiaries. Groupe ADP details its policy in its Act For Nature commitments: Area 1: Protect key natural environments at airports in line with ecological continuity Area 2: Give biodiversity back the space it needs in urban environments and develop low-impact construction models that support life Area 3: Mobilise the players in the airport community and beyond to reduce the pressures on our value chain Area 4: Raise biodiversity to a strategic level, and develop the appropriate governance tools to manage it. Main actions related to biodiversity: – Measuring biodiversity (fauna-flora surveys, indices, operational indicators, etc.) – Protecting and sustainably managing habitats – Reducing the pressures associated with our infrastructure and buildings – Living safely with birdlife – Anchoring ourselves in the regions, and working with the airport community and the entire value chain – Aligning with institutional frameworks

Actions

* The consolidated scope is as described in DR BP-1.

In order to reduce the pressure on biodiversity and improve the resilience of its business model in the face of biodiversity collapse, Groupe ADP is committed to biodiversity. Its approach is structured by the act4nature commitments, and consolidated within the environmental policy and voluntary strategic commitments made in 2022 within the new 2025 Pioneers for Trust roadmap (see section 4.2 “Environmental Matters”). In 2024, Groupe ADP strengthened its biodiversity resources and ambitions in order to renew its commitments within the act4nature international initiative for the 2025-2030 period. These new commitments have made it possible to integrate the results of the dependencies and impacts study to meet the challenges of the Group's material topics, to raise the level of integration of international assets and to extend the scope of the commitments to the entire value chain – see [E4-2-22] → Policies to manage material impacts, risks and opportunities related to biodiversity and ecosystems [see ESRS 2 – MDR-P].

The biodiversity risks identified in the Vigilance Plan mirror the requirements of the CSRD. The issues 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) and specifically presented below: Description of the “biodiversity” risk as defined in the Vigilance Plan Groupe ADP's responsibility and the challenges it faces in contributing to the erosion of biodiversity must be considered throughout the value chain. These risks are little known within the airport community and vary depending on the sites studied (see SBM-3 — Identification of important Groupe ADP sites and potential negative impacts). However, the collapse of biodiversity is causing tensions over supplies, the emergence of zoonoses 1 and difficulties in carrying out hub development projects due to the land artificialisation they underpin and the direct and indirect impact of this activity on ecosystems and living populations.
