SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

[E4-3-28-(a)] → Information on how the mitigation hierarchy with regard to biodiversity and ecosystems has been applied Non-mandatory, not processed in 2024. [E4-3-28-(b)] → Information on whether biodiversity offsets were used in its action plans The Paris hubs are deliberately ambitious in their application of the Avoid-Reduce-Compensate (ERC) principle. Thanks to this practice, they have managed to avoid or reduce all of these impacts on the biodiversity of the projects concerned, so that they have not had to resort to regulatory compensation. The Group also voluntarily finances restoration projects, but these are not accounted for as impact compensation. Groupe ADP has launched a study with a view to defining its biodiversity trajectory towards a net contribution of Groupe ADP's activities to nature, including scenarios for the purchase of biodiversity credits. Finally, the new biodiversity commitments include the systematic assessment of carbon offset projects, with a view to guaranteeing their biodiversity co-benefits. [E4-3-28-(b)-i] → Disclosure of the aim of the biodiversity offset and key performance indicators used Response given in E4-3-28-(b). [E4-3-28-(b)-ii] → The financing effects (direct and indirect costs) of biodiversity offsets In 2024, no project was subject to regulatory compensation. [E4-3-28-(b)-iii] → Description of biodiversity offsets Regulatory biodiversity offsetting The Reconquête de la biodiversité law requires the implementation of the so-called ERC principle (Avoid Reduce-Compensate) for all projects requiring environmental authorisation. For these projects, the Group implements environmental measures to ensure a high level of sustainability in order to limit compensation. To do this, the Group favours the voluntary Avoid-Reduce-Support sequence. In 2024, environmental authorisation was granted for the Orly des Avernaises project, enabling it to be implemented without any exemptions for protected species or compensation. In addition, Groupe ADP keeps its stakeholders informed every two years of biodiversity offsetting projects at the hubs for which it is responsible. Voluntary nature restoration projects Groupe ADP already finances voluntary restoration projects on and beyond its hubs, but these are not valued as carbon or biodiversity credits. As part of the Nature 2050 project supported by CDC Biodiversité, the Group has already financed 10,000 sq.m. of renaturation work.

3. Reducing the pressures associated with our infrastructure and buildings The Paris region hubs are working to implement actions to promote biodiversity in the urbanised areas of each hub. The integration of biodiversity into the construction process is reflected, for example, in the definition of specific requirements and the compliance of new buildings with environmental labels such as BREEAM and LEEDS. The Planning, Sustainable Development and Public Affairs Department is also studying the possibilities for developments adapted to biodiversity through the Landscape and Biodiversity Master Plans. The year 2024 also gave rise to a set of internal environmental standards, including a specific chapter on biodiversity, designed to help project owners and contractors make biodiversity-friendly design and construction choices. These environmental standards will be implemented from 2025 onwards. 4. Living safely with birdlife Groupe ADP's approach is to work to improve our knowledge of species in order to better understand their behaviour and reduce the risk of collisions. The animal risk prevention services are trained to recognise species and adapt scaring methods on a case-by-case basis. These teams, in particular, use sound and visual scare tactics. More recently, the Paris hubs tried out new, more systemic methods such as creating diversion zones. For example, Paris-Charles de Gaulle has developed areas away from runways to make them attractive to at-risk birdlife. Paris-Orly is also studying the behaviour of birdlife in order to propose conservation measures for each species. 5. Anchoring ourselves in the regions, and working with the airport community and the entire value chain Groupe ADP encourages its partners, customers and suppliers to support biodiversity. In 2024, the Group organised a number of events to encourage them to get involved. These events are described in paragraph [E4 ESRS 2 IRO-1-17-(e)] → Description of how consultations with affected communities on sustainability assessments of shared biological resources and ecosystems were conducted. 6. Raising awareness and mobilising employees The year 2024 was marked by an increase in employees' commitment to protecting nature. As a result, 68% of the citizen involvement actions were carried out with nature conservation associations such as the Pariciflore association nursery or the "Au fil de l'eau" association. In 2024, there were also 36 employees in charge of animal risk prevention, trained in fauna-flora recognition and associated biodiversity conservation practices, as well as more than 210 employees made aware of biodiversity through the eponymous fresco. 7. Aligning with institutional frameworks The year 2024 saw the first assessments of the alignment of the Group's activities with international biodiversity frameworks. An initial assessment of how the Group's actions relate to the targets of the Kunming Montréal Framework was therefore carried out.
