SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

[E2-1-15-(b)] → Disclosure of whether and how the policy addresses substituting and minimising the use of substances of concern, and phasing out substances of very high concern Aéroports de Paris SA keeps a register of the chemical products used on its Paris hubs. The company applies the best available techniques to reduce occupational risks and risks to people living near airports. ADP has a policy of not using hazardous or extremely hazardous chemicals where alternatives exist. Thus, at this stage, and within the limits of our knowledge on the compositions of commercially-available products, Aéroports de Paris does not use any substances of concern or of very high concern on its Paris hubs. [E2-1-15-(c)] → Disclosure of whether and how the policy addresses avoiding incidents and emergency situations, and if and when they occur, controlling and limiting their impact on people and the environment The main impacts on air quality attributable to activity at the Group's controlled airports are predominantly from energy production facilities (see [E2-ESRS 2 IRO-1-AR 9] → Disclosure of the outcome of the materiality assessment (pollution) and [E2-1-15-(b)] → Disclosure of whether and how the policy addresses substituting and minimising the use of substances of concern, and phasing out substances of very high concern). These facilities are subject to operating authorisations. These authorisations are issued by the relevant authorities: ministries, prefectures, sectoral control authorities, depending on the case and the region. They define the In the event of an information-recommendation procedure u Adapting the set-point temperature in certain areas of airports at certain times. u Reducing the operation of fixed installations whose emissions contribute to the pollution episode. u Implementing specific requirements set out in the operating authorisation for Installations Classified for the Protection of the Environment. [E2-1-AR 12] → Information on contextual information on the relations between its policies implemented and how they may contribute to the EU Action Plan “Towards a Zero Pollution for Air, Water and Soil” Section not required in 2024. [E2-1-14] → Policies in place to manage material impacts, risks and opportunities related to pollution [see ESRS 2 MDR-P] As described in [E2-ESRS 2 IRO-1-AR 9] → Disclosure of the outcome of the materiality assessment (pollution), the air quality management policies of each Group entity are mainly based on compliance with regulatory obligations and the search, in constant liaison with the relevant authorities, for the best possible adaptation of the frameworks to changes in the Group's activities.

operating and monitoring conditions, compliance with which helps to avoid environmental emergencies. Site safety regulations also help to prevent incidents and accidents. In France, these discharges are governed by prefectural decrees describing the pollutant discharge thresholds that must be respected. An incident that could have an impact on air quality is defined as an event that results in emission thresholds being exceeded. In this case, an emergency procedure is applied. It consists of immediately shutting down the means of production (boiler) in order to stop non-compliant emissions. Production only resumes once the incident is over. In addition to strictly material emissions linked to energy production, regional air pollution episodes frequently occur in the Île-de-France region, and information recommendation and alert procedures are triggered by Airparif, specifying the actions to be taken to limit pollution. Groupe ADP's Paris airports are affected. In the event of a prolonged episode, some of these actions, and in particular the national civil aviation action plan (managed by the French Directorate General for Civil Aviation (Direction Générale de l'Aviation Civile – DGAC)), may lead to operational restrictions. For its Paris hubs, Aéroports de Paris SA has defined an internal procedure for managing episodes of air pollution, which specifies the actions to be taken by all the entities that can act to limit emissions during episodes of air pollution. It is based on awareness-raising actions – informing Aéroports de Paris employees, the aviation community and all people visiting our hubs – and includes actions to reduce emissions, for example: u Postponing maintenance work and certain operations that emit particles, nitrogen oxides or volatile organic compounds. u Reducing the use of generators. u Reducing the use of solvents. u Reminding external operators of best practices in the event of a pollution episode. u Postponing or reducing activity on dust-generating work sites and implementing avoidance measures wherever possible, without jeopardising aviation safety and in compliance with contractual provisions. The regular updating of these local requirements and their availability in languages that differ from the local language (in particular English or French) makes listing them complex and even hazardous. Responsibility for compliance with standards and regulations lies with the operations and local governance teams. However, we can cite the following examples: In France, these impact management policies are based on prefectural decrees: CDG: u CTFE: Decree No. IC 20-107; u CTFE Bis: Update of the requirements of AP DAIDD IC 3278 of 21 December 2007.
