RAISING AWARENESS AND PARTICIPATORY SCIENCE The regular observation sessions carried out in partnership with Aérobiodiversité resumed their normal pace in 2021, with more observation days conducted independently by the green spaces and animal risk teams. Distancing measures and operational constraints did not allow for the expected rate of visits by the public; however, a school visit and a delegation of elected officials were welcomed at Paris-Charles de Gaulle. Exchanges of information and best practices are maintained with local authorities, in particular through a partnership agreement with the Seine-et-Marne departmental council. The preservation of water resources and their sustainable management are essential and an integral part of the Aéroports de Paris environmental and energy policy. Even though the situation currently varies widely according to the sectors in which the Group’s airports are located (as regards the level of water constraints), climate change is forcing us to think about future capacities to meet water needs in relation to airport development. For water, the Aéroports de Paris environmental and energy policy set three objectives for 2021: ◆ update the action plan to reduce internal consumption of drinking water per passenger and strengthen metering by increasing the number of specific meters per customer; ◆ as part of a water masterplan, define rainwater management rules by zone taking into account adaptation to climate change; ◆ continue to improve the management of winter pollution. Aéroports de Paris distributes drinking water at its airports and has a water tower and booster pump at Paris-Charles de Gaulle, whereas Paris-Orly and Paris-Le Bourget are supplied by drinking water distribution points. To reduce its internal consumption of drinking water per passenger, Aéroports de Paris: ◆ recycles the water that comes out of its rainwater treatment and purification systems for different uses (such as powering the air-cooling towers at Paris-Orly or sanitary blocks, for instance); ◆ installs water-saving equipment, especially in the sanitary areas of its terminals; ◆ uses more reliable measuring equipment (remote meter reading) for monitoring and detailed analysis of consumption; ◆ informs and trains staff on the use of water resources, products and equipment. Regarding rainwater management, in addition to pollution catch basins and retention basins, at its Paris-Orly and Paris-Charles de Gaulle airports, Aéroports de Paris has rainwater treatment systems that enable it to meet the regulatory requirements for discharge into the natural environment imposed by inter prefectural orders specific to each airport. At Paris-Orly, for example, a 2,000 m 2 wetland filtration facility optimises this treatment, and at Paris-Le Bourget, filtering technique trials are underway. The rainwater collection and treatment network has been restructured at all French airports, which also have guidelines on rainwater management. Water conservation Policy and objectives

took advantage of this momentum to formalise its new post 2020 biodiversity commitments. These commitments, published in October 2020, are public 1 . The dynamics of this re-engagement are twofold: ◆ internationalisation: the main principles are validated by the Group’s international assets, and each airport will thus roll out a roadmap and monitor actions in favour of biodiversity; ◆ extension to the Group’s entire value chain and spheres of influence, from upstream to downstream: suppliers, airlines, shops, regions, etc. Of particular note are the following commitments: ◆ assessment of the biodiversity footprint, definition of a metric adapted to the Group’s activities; Groupe ADP’s commitments relating to biodiversity include the commitments made by Groupe ADP in 2020 and 2021 as part of act4nature international and Entreprises Engagées pour la Nature . They are described in the paragraph “The 2022-2025 environmental policy”. 2021 achievements and results KNOWLEDGE OF THE LAND AND ITS DEVELOPMENT To achieve these objectives, Aéroports de Paris defines development, landscape and biodiversity blueprints for its Paris Charles de Gaulle, Paris-Le Bourget and Paris-Orly airports. These documents are based on biodiversity diagnostics and aim to reconcile the development of the airports with the preservation, then the strengthening, of biodiversity. They are being rolled out into operational strategies: that of Paris-Charles de Gaulle was finalised in 2021, and that of Paris-Orly is underway and should be finalised in early 2022. RESPONSIBLE MANAGEMENT OF GREEN SPACES AND BIODIVERSITY Thanks in particular to a better understanding of the biodiversity present at the airports, green space management practices are changing and the reduction in the use of plant protection products is continuing, with an 80% reduction in use at the end of 2020 compared to 2008 (three-year average), exceeding the target for 2020 (-60%). Paris-Orly maintains its zero-phyto management, as does Liège airport. Today, in line with the zero phyto approach, animal risk management teams are increasingly adopting a preventative approach and are working toward integrated biodiversity management by creating synergies between the management of our green spaces to achieve a better ecological balance on our land. This performance earned Paris-Orly two labels at the end of 2021: Ecojardin, awarded by the EcoJardin Plante & Cité labeling committee for the quality of the management of green spaces throughout the platform, and Aérobio level 3, awarded by Aérobiodiversité , a new label dedicated to airports to promote their commitment to the responsible management of fauna and flora. In addition, Paris Charles de Gaulle has strengthened its zero-phyto trajectory by developing the “BiodiversIT” innovation project as part of the European OLGA project, and by initiating an experiment with autonomous robot mowers, supported by the French Biodiversity Office as part of the “ Aéroports Zéro-Phyto ” project. This project, managed by the UAF with the support of ADP, was the winner of the ecophyto call for projects in 2021. ◆ generalisation of “zero phyto” over time; ◆ Zero Net Artificialisation feasibility study.
