SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

Develop an industrial and regional ecology strategy for construction materials and energy Policy/Objectives and Main Actions for 2024 Groupe ADP aims to reduce its dependence on natural resources and limit its impact on them. The construction sector is the main producer of waste on a national scale (around 60% of waste tonnage), and Groupe ADP is no exception on a French and international scale. In 2023, Groupe ADP carried out a study to identify and provide an initial quantification of its dependence on these various non-living resources. Groupe ADP is convinced that, even if the availability of certain resources is an international issue, regional solutions are and will be an important part of the possible response to these issues. The main lessons learned from this study are: u Groupe ADP is dependent on raw materials whose intrinsic criticality (availability at global level) is not very critical in terms of inventories. However, some of these activities (particularly aeronautics) are dependent on the most critical resources in the panel studied (particularly ores and metals and the availability of aviation fuels, especially paraffin); u real estate and airport development activities are highly dependent on a wide variety of resources that are difficult to replace: sands and aggregates, metals, and materials from living organisms; u the relative vulnerability of aeronautical (aircraft production, air traffic control, passenger reception) and real estate (airport development and planning, diversification real estate) activities to specific natural resources such as sands, aggregates, minerals, water, etc.; u the specific vulnerability of activities related to the ecological transition (production of sustainable aviation fuels, hydrogen and low-carbon energies). This transition risk is taken particularly seriously by Groupe ADP so that it can guarantee the conditions for the successful completion of its ecological transition by respecting the indicated time horizons. With regard to materials, Aéroports de Paris SA signed the Metropolitan Charter for Circular Construction of the Greater Paris Metropolitan Area. The metropolitan charter for circular construction aims to amplify, accelerate and massify best practices, including the scaling up within a structured market. This last point is now essential to meet the economic, social and environmental challenges of our city. Through this commitment, Groupe ADP wishes to get behind this momentum. To this end and in support of the results of its dependency study mentioned above, Aéroports de Paris SA has engaged in exchanges with major players in the region to identify possible avenues for the circular economy with its Parisian host regions (the regional public establishments of Grand Orly Seine Bièvre and Paris Terre d'Envol, the Communauté d'Agglomération Roissy Pays de France, the Greater Paris Metropolitan Area), non-profit organisations (OREE, Entreprises pour l'Environnement), state bodies (CSTB, ADEME, ENPC), other major public and private project managers (EDF, RATP, VNF, Vinci, Bouygues, etc.). The purpose of these exchanges is to participate in the emergence of a circular economy at the metropolitan and national level so that the Group is a stakeholder.

u which will see existing infrastructures densified and the capacities of stations and multimodal hubs extended, using new innovative and environmentally-friendly construction methods; u will be integrated into global urban planning, by being at the heart of the regions on issues of real estate, energy, or mobility through dialogue and enhanced cooperation with our regions of influence. Groupe ADP will rely in particular on the following projects, whose commissioning is scheduled after 2025: u the opening of line 18 of the Grand Paris Express in 2027 to further improve access to Paris-Orly airport; u the opening of line 17 at Paris-Le Bourget in 2026 and at Paris-Charles de Gaulle in 2028; u the opening of the CDG Express line in 2027 between Paris-Est and Paris-Charles de Gaulle; u the opening of the Picardie – Paris-Charles de Gaulle line in 2025. This new airport model puts its relationship with airport regions at the heart of its concerns. This is particularly the case at Paris Charles de Gaulle, Paris-Orly and Paris-Le Bourget in order to: u streamline travel within the hubs (reduce the use of cars and promote collective or active modes of transport); u promote and improve connections with public transport; u increase the modal share of long-distance trains (with respect to the origin of both departing and arriving passengers, in particular to supply long-haul flights); u improve accessibility for employees, air passengers and commuters (between Paris, the regions and the hub) but also to stabilise the contribution of the Paris-Charles de Gaulle hub in terms of the number of vehicles on the road accesses insofar as possible at the 2019 level; u to design a new development project for Paris-Orly 2035, which was the subject of a public consultation in 2024, and which focuses on the overhaul of accesses to accelerate the modal shift by the implementation of internal public transport connecting the multimodal station (Grand Paris Express with line 15 and, from 2027, line 18 and a national bus station), the terminals, the main employment areas, and new remote car parks; u integrate and develop public transport serving the hubs (buses, express coaches, tramways) while promoting new uses (car-sharing/carpooling, active modes, innovative mobility, etc.). Main actions The main actions included in this decarbonisation lever are described in part S4-4 – Action plans put in place to prevent, mitigate and remediate the impacts associated with access to the hub and multimodality, and in particular in paragraphs S4-4-30 and S4-4-31-a. Lever 4 – Reducing the carbon footprint of its construction processes, by integrating innovative practices and technologies aimed at reducing the environmental impacts of its investment projects To achieve its decarbonisation targets in terms of construction, Groupe ADP is focusing on two main areas: on the one hand, the development of an industrial and local ecology strategy focusing on construction materials and energy; on the other hand, the implementation of a low carbon construction and circular economy policy, based on limiting the number of buildings, their modularity and flexibility, as well as on environmental governance incorporating a carbon budget and biodiversity preservation targets.
