[S3-4-AR 25-(a)] → [S3] Disclosure of general and specific approaches to addressing material negative impacts

committed to the environmental transition of Paris Orly airport, setting five common targets, including one related to noise pollution: u a reduction of 6 dB at night (10 p.m. to 11.30 p.m.). ADP SA is also a member of the Union des aéroports français (UAF) and the Conseil pour la recherche aéronautique civil (CORAC). ADP SA plays an active role in these bodies, particularly on issues relating to aircraft noise and aviation activities in the broadest sense. [S3-4-AR 43] → [S3] Description of internal functions involved in managing the impacts and types of actions they take to remediate negative impacts and advance positive impacts The internal functions involved in managing the impact of noise pollution are as follows: u Executive Director Sustainable Development and Projects; u Department of Planning, Sustainable Development and Public Affairs; u Soundproofing Assistance Department; u Regional Actions Department (Maison de l’Environnement). S3-5 – Targets for noise reduction [S3-5-41] → Targets set to manage material impacts, risks and opportunities related to affected communities [see ESRS 2 – MDR-T] Noise level improvement targets will be set at the end of the EIAE exercise at Paris-Charles de Gaulle airport, for which public consultation is currently underway under the aegis of the Prefect of Val-d'Oise. They aim to measure changes in noise using the Lden (day-evening-night) and Lnight (during the night) indicators to quantify the number of people affected by the harmful effect and to set a percentage change in the population affected, with a tolerance of ±5% Two metrics are provided for by Directive 2020/367: 1. HA55: number of people severely affected by noise throughout the day on the Lden 55 noise level curve; 2. HSD 50: number of people severely affected by noise at night on the Lnight 50 noise level curve: u 1 st target: over a full day, reduce the amount of people affected according to HA55 by a third, i.e. , between 28% and 38%, u 2 nd target: halve the number of people affected at night. I.e. , reduce HSD50 by between 45% and 55%. For Paris-Orly airport, reduction in noise pollution targets have been set in the Paris-Orly airport PPBE 2018-2023, approved by inter-prefectural decree no. 2022/00949 of 17 March 2022, and serve as a framework for the impact study based on the current balanced approach. The two targets are, in relation to the reference situation (2018) and the horizon of return to 2018 traffic levels (estimated in 2026): u a reduction of at least 6 dB in average Ln value during the period 10 p.m.-6 a.m. in the L night >50 bracket. From the point of view of auditory sensations, a reduction of 6 dB is clearly perceptible and corresponds to doubling the distance from the sound source; u within the same scope, a halving of the High Sleep Disturbance (HSD) health indicator. Note that this indicator records the number of people affected by severe sleep disturbance.

See [S3-4-32-(a)] → Description of actions taken, planned or underway to prevent, mitigate or remediate material negative impacts on affected communities. [S3-4-AR 25-(b)] → S3] Disclosure of social investment or other development programmes aimed at to contributing to additional positive impacts The Maison de l’Environnement programme and the commitment of its teams provide a lever for action beyond the field of noise pollution by setting up stands and educational content such as films and workshops. All year round, the Maisons de l'Environnement welcome schools, associations and companies to help them discover airports and their professions. Films on the company's CSR strategy or on the soundproofing assistance scheme are produced and shown at the Maison de l’Environnement. Workshops are held at the Maison de l’Environnement by the various departments, and exhibitions relating to airport activities are on display for all visitors to see. [S3-4-AR 25-(c)] → [S3] Information on how far the company has progressed in its efforts during the reporting period In 2024, 566 new soundproofing requests were submitted to and accepted by the ACLR. As a result, 1,900 homes were soundproofed during the year, for a total of €19.4 million in aid. [S3-4-AR 25-(d)] → [S3] Disclosure of continued Implementation of a "progress loop" process designed to optimise the processing of soundproofing requests, and implementation of an annual "customer" quality survey designed to identify areas for improvement. The educational tools used by the Maisons de l’Environnement for the general public are reviewed each year to make additions and improvements to facilitate understanding of potentially complex technical subjects. In addition, a working group between ACNUSA, an honorary prefect, the airlines and ADP SA has been set up at Paris Charles de Gaulle airport to monitor night flights and ensure compliance with the ceiling set. [S3-4-AR 27] → Description of whether and how the company seeks to use its leverage in its business relationships to manage material negative impacts on affected communities ADP SA implements a pricing policy through the fees paid by airlines that encourages the deployment of modern aircraft fleets with a lower noise impact.

[S3-4-AR 28] → [S3] Communication of how participation in an industry or multi-stakeholder initiative and the company's own involvement aim to its address material impacts Groupe ADP has initiated the creation of an environmental alliance for the airport community at the Paris-Orly hub. Launched in 2023, it now includes 38 partners such as airlines, ground handlers, service providers, hotels, stores and French government departments, and is collectively improvement objectives Help with soundproofing
