[E4-ESRS 2 IRO-1-17-(e)-iii] → Description of whether and how impacts on ecosystem services of relevance to affected communities may be avoided To date, no negative impact on ecosystem services of relevance has been identified that would affect the If, however, the studies launched in 2025 lead to the identification of such impacts, they would then be taken into account in a mitigation plan, which itself would be made public and implemented in compliance with the relevant regulations. [E4-ESRS 2 IRO-1-17-(e)-iii] → Disclosure of plans to minimise unavoidable impacts to ecosystem services of relevance and implement mitigation measures that aim to maintain the value and functionality of priority services To date, no negative impact on ecosystem services of relevance has been identified that would affect the If, however, the studies launched in 2025 lead to the identification of such impacts, they would then be taken into account in a mitigation plan, which itself would be made public and implemented in compliance with the relevant regulations. [E4-ESRS 2 IRO-1-18] → Whether and how the business model(s) have been verified using a range of biodiversity and ecosystems scenarios - or other scenarios with a modelling of biodiversity and ecosystems-related consequences - with different possible pathways The study launched by Groupe ADP in 2025 to draw up a transition plan towards a new business model in line with the preservation of biodiversity includes the evaluation of scenarios that would enable Groupe ADP to align its business model with the preservation of biodiversity. u The study will be based on major international advances (in particular from the Conferences of the Parties on Biological Diversity) and the new EU and French institutional and regulatory frameworks, such as the European Union's 2030 Biodiversity Strategy. The study will include explanations of the choice of scenarios and their updating. [E4-ESRS 2 IRO-1-19-(a)] → The company has sites located in or near biodiversity-sensitive areas Groupe ADP has carried out a survey of biodiversity sensitive areas in the vicinity of its sites according to internationally recognised areas: Natura 2000 protected areas, UNESCO World Heritage sites, Key Biodiversity Areas, RAMSAR sites 1 and protected areas according to the World Database of Protected Areas. In addition, at site level, Groupe ADP carries out fauna-flora habitat inventories for its three hubs in the Paris region, enabling it to assess the matters at stake at its sites. For these sites, certain key species have been identified and are subject to special monitoring. communities surrounding the Group's airports. As a result, no avoidance plan has been created. communities surrounding the Group's airports. As a result, no avoidance plan has been created.

[E4-ESRS 2 IRO-1-19-(a)] → Activities related to sites located in or near biodiversity-sensitive areas which negatively affect these areas by leading to the deterioration of natural habitats and to the disturbance of the protected species Groupe ADP has identified disturbances to species caused by air traffic activities. Indeed, the movement of birdlife close to the runways and in the first few kilometres of airways around runways can cause collisions. Collisions with birds can cause disturbance to local and migratory birdlife. In addition, airport operations and construction activities can damage habitats and disturb species, both during construction (noise disturbance, earthworks) and afterwards (structural modification of habitats). The sensitive areas identified were listed in the previous chapter. See DP: [E4-ESRS 2 SBM-3-16-(a)-iii] → Disclosure of the biodiversity-sensitive areas impacted [E4-ESRS 2 IRO-1-19-(b)] → Whether it has been concluded that it is necessary to implement biodiversity mitigation measures Groupe ADP has concluded that it is necessary to implement measures to limit the pressure on the habitats present on and near its hubs, paying particular attention to protected species. To this end, it has set out in its environmental policy a number of commitments within each of the four pillars of its environmental policy aimed at mitigating biodiversity matters, such as: u commitment 1.5 to preserve the environment: water, soil, and biodiversity; reduce the biodiversity footprint of our value chain; u commitment 2.3: contributing to exemplary environmental work in the aviation sector, in particular focusing on the fight against the trafficking of protected species; u commitment 3.3 being a privileged partner of the regions and scientific and non-profit organisations in terms of biodiversity conservation and awareness; u commitment 4.3 Improve the ecological value of our sites, ensure ecological continuity and aim for Net Zero Waterproofing, as part of our project management responsibility and based on an ambitious pathway validated in 2022. E4-1 – Resilience of Groupe ADP business model to biodiversity risk Groupe ADP's business model explicitly mentions the need for the Group's strategy to be consistent with limiting its pressure on biodiversity and resilient with regard to its dependencies. A first step was taken in 2022 by measuring the biodiversity footprint of Paris airports and identifying their direct and indirect pressures. To go further, Groupe ADP has decided to carry out a new study in 2025, including the consolidated scope and aiming to integrate transition scenarios for the business model in order to analyse its resilience in the face of biodiversity matters.
