u limiting the use of engines for taxiing (deployment of the practice of N-1 motor taxiing, gradual introduction of aircraft towing or autonomous taxiing). This practice is becoming more widespread at several Group airports in France, Croatia and several TAV Airports Group airports, for example; u the massive deployment of electrical utilities (400 Hz and ACU – Air Conditioning Units) at the level of aircraft stands in order to limit the use of APUs (Auxiliary Power Units, running on kerosene) of aircraft and/or GPUs (Ground Power Units – ground-based combustion generators) for the supply of electricity and air conditioning during ground-handling operations; u the development and implementation of a decarbonisation trajectory for ground-handling equipment and vehicles covering both the greening of equipment fleets and the deployment of low-carbon/decarbonised energy recharging utilities (electric charging stations, bioNGV and low-carbon hydrogen distribution stations, etc.) in Paris, for example. It should be noted that the introduction of new aircraft energies such as electricity, sustainable aviation fuels (SAF) and hydrogen (see paragraph above) will also help to reduce the carbon footprint of aircraft emissions during the flight phases below 3,000 feet and during taxiing. Metrics u Percentage of low-carbon light vehicles (airport operator's fleet) (low-carbon = electric/bio-NGV/low-carbon hydrogen): this indicator makes it possible to monitor the change in the share of vehicles within the airport; u Paris-Charles de Gaulle: 35% u Paris-Orly: 39% u Paris-Le Bourget: 14% u Percentage of low-carbon ground handling vehicles and equipment; u Paris-Charles de Gaulle: 55% u Paris-Orly: 50% u Paris-Le Bourget: 59% Main actions The actions taken in 2024 were a continuation of those undertaken since 2021 at hub level: u Continued deployment of electrical units at aircraft stands and in parking areas for ground handling vehicles and equipment. Electrification work at the Paris-Orly and Paris Charles de Gaulle hubs, in order to meet the new electrical needs that are appearing on the hubs (electric mobility, electric alternative to APUs – auxiliary power units for aircraft – electricity supply for the future heat pump in the case of Paris-Orly). Aéroports de Paris SA receives support from the European Commission, via the CEF AFIF (Connecting Europe Facility – Alternative Fuels Infrastructure Facility) mechanism, for its two electrification projects. These projects, respectively entitled GLORYA (Green eLectrification ORY Airside) and ClearCDG (Collaborative Electrification Airside at CDG), aim for an ambitious strengthening of the electrification of the two hubs by 2025-2026. u Testing of Green Taxiing solutions (assisted and less emissive aircraft taxiing) at Paris-Charles de Gaulle, Paris Orly and Paris-Le Bourget airports. At Paris-Charles de Gaulle, Aéroports de Paris, in conjunction with Air France, Smart Airport System and DSNA, and as part of the OLGA project, is testing the taxibot system, which allows aircraft to be towed with their engines off. The experiment, which continued until March 2024, aimed to establish the

feasibility of using the taxibot on a runway at Paris-Charles de Gaulle, under real operational conditions. Four medium haul aircraft operated by Air France were adapted to carry out these tests. The analysis report is currently being drafted. u As a reminder, in 2021, the selection of stop-over assistants at Paris-Charles de Gaulle and Paris-Orly was carried out on the basis, among other things, of a criterion for the greening of their vehicles heavily weighted during the consultation. The selection process made it possible to define the objective of achieving 75% clean machines by 2025 for limited services (related to baggage handling and aircraft movements). Groupe ADP also announced a target of 90% clean vehicles by 2030 for limited services. u Enfidha airport is also committed to modernising its ground handling equipment (GSE) by replacing existing vehicles with electric and clean vehicles, as part of its approach to sustainability and reducing its environmental footprint. u Aéroports de Paris SA is carrying out projects for the deployment of H2/bioNGV distribution stations at Paris Orly and Paris-Charles de Gaulle, to supply vehicles and machines both in reserved areas, on the airside, as well as in public areas. This system will complement the offer already in place at the hydrogen stations located on the city side, and mainly used by hydrogen taxis. For example, in October 2024, the first two TotalEnergies multi-energy service stations were inaugurated at Paris-Charles de Gaulle. A hydrogen filling station at Paris-Le Bourget was also inaugurated in March 2024. Built by HysetCo, the station has a distribution capacity of 1 tonne per day and is located at a strategic road junction. The Group is also reserving plots of land and undertaking feasibility studies at Paris-Charles de Gaulle and Paris-Orly, in conjunction with energy companies, for the installation of new hydrogen/bioNGV (Natural Gas Vehicle) distribution stations. Lever 3 – Strengthen rail/air intermodality, reduce the use of individual vehicles, strengthen connectivity with the regions and make airport platforms real intermodal hubs at the regional and national levels Land mobility is an important factor in social cohesion and the attractiveness of regions for access to employment. Groupe ADP, aware of the importance of carrying out improvements to strengthen long-distance intermodality and regional and local multimodality, takes into account the complementarity between the modes of transport, on its rights-of-way and in connection with the various territories in which it operates throughout the world. Thus, the essential articulation of these different modes of transport to get to the platforms is aligned with the Group's desire to move towards operations with zero impact on the environment. Policy/Objectives Groupe ADP's environmental and energy policy is based on the desire to build the foundation of a new airport model focused on sustainability and performance, in line with societal and environmental expectations. The Group now wants to make its airports multimodal and energy-efficient hubs, designed and operated in a sustainable manner: u which will no longer be just a place to fly, but a place where one benefits from renewed and decarbonised connectivity, offering travellers a choice between different modes of travel (long- and short-distance rail, bus, soft mobility, etc.), and where rail-air connections will account for a growing share of the development of traffic at Groupe ADP's hubs;
