4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

[E4-2-24-(b)] → Whether sustainable land/agriculture practices or policies have been adopted Historically, Groupe ADP has had to manage land as part of its construction and development projects. Aware of the associated biodiversity matters, the Group is starting an experiment at Paris-Charles de Gaulle airport in 2025, with the aim of introducing systematic land management in the medium term. The methodology tested aims to include land management in the master plan. The volume of soil to be excavated was assessed for each project. Working with the in-house laboratory, the hub will then characterise the geological composition of the soil and define a strategy for storing it. The associated management methods will be structured according to their geological characterisation and storage time. The land will subsequently be managed ecologically or reused for other projects. Groupe ADP's ambition is to systematise the best practices that emerge from the feedback from the experiment and to extend this strategy to a wider range of hubs. In addition, the Paris region hubs are implementing differentiated management plans for all their semi-natural environments. These management plans include practices such as a zero phytosanitary approach, late mowing plans, tall grass practices, mulching, work to stabilise the spread of invasive exotic species and nature renovation practices, including the selection of endemic species. These practices also aim to ensure the sustainable management of the environment by preserving the habitats of and attracting the associated endemic species. [E4-2-24-(c)] → Whether sustainable oceans/seas practices or policies have been adopted Not applicable. Oceans and seas have not been considered as material natural environments related to the impacts of Groupe ADP. [E4-2-24-(d)] → Whether policies to address deforestation have been adopted The new CSR suppliers' charter, updated in 2024, includes 13 principles, one of which addresses the preservation of biodiversity. Among other things, it highlights the issue of imported deforestation, and suppliers who are signatories to the charter are asked to take this matter into account. In addition, the new biodiversity commitments include ambitions in terms of responsible purchasing, which include improving our monitoring of imported deforestation matters. Groupe ADP has therefore undertaken to identify priority impact sectors in its purchasing and to support them through a partnership approach with a view to reducing the impact of our upstream value chain. The identification study is currently being carried out for the 2025.

E4-3 – Summary of actions to promote biodiversity over the 2023-2024 period (detailed description including monetary amounts) [E4-3-27] → Actions and resources related to biodiversity and ecosystems [see ESRS 2 – MDR-A] 1. Measuring biodiversity Historically, airports have observed the biodiversity present on a daily basis, particularly in reserved areas (airside) for aviation safety reasons, in particular to avoid bird collisions. Biodiversity observation data are tracked, historically, by the hubs. At the same time, to improve their knowledge, the Paris hubs carry out annual fauna and flora inventories with the support of the Aérobiodiversité association. In 2022, Groupe ADP measured the overall biodiversity footprint of the Paris hubs through the Corporate Biodiversity Footprint for the first time. This approach revealed the new challenges facing the Group. In 2024, the Group will extend the scope of its biodiversity measurement to international airports. For example, the TAV subsidiary's airports have planned ecological inventories for ten sites, enabling studies to be launched for Antalya, Almaty, Ankara and İzmir airports and studies to be planned for 2025 for the Milas Bodrum, Tbilisi, Macedonia and Batumi airports. At the same time, the Group is working on consolidating its biodiversity data, using a mapping tool common to all hubs. 2. Protecting and sustainably managing habitats The Paris hubs are honouring their commitment to preserving 25% (Paris-Charles de Gaulle) and 30% (Paris Orly and Paris-Le Bourget) of their space for biodiversity. These areas, mainly made up of permanent grassland, are recognised by the National Biodiversity Strategy for their ecological value, constituting real reservoirs of biodiversity in a particularly urbanised area. In order to maintain the ecological characteristics of these environments, the Paris hubs are implementing reasoned management practices for their green spaces, such as (i) differentiated mowing plans adapted to usage and favouring late mowing, allowing the grassland in certain areas to be left in a complete vegetation cycle, (ii) practices to maintain tall grass (iii) or even mulching and mechanical weeding practices, in particular to combat invasive exotic plants. By 2024, 47% of the surface area of the Paris-Charles de Gaulle hub was managed using late mowing. These management practices have been praised by several labels. Paris Charles de Gaulle and Paris-Le Bourget have been awarded level 2 of the Aerobiodiversity label and Paris Orly has been awarded level 3. Paris-Orly has also become the largest airport with the Ecojardin label. Lastly, all three Paris hubs have succeeded in achieving a zero phytosanitary approach by 2024, an approach voluntarily initiated in 2008 at Paris-Orly.
