[E2-3-23-(a)] → Description of whether and how the target relates to the prevention and control of air pollutants and respective specific loads Information available in previous chapters: u types of checks carried out: [E2-2-18] → Actions and resources related to pollution [see ESRS 2 – MDR-A]; u linking objectives to the prevention of air pollution: [E2-3-22] → [E2] Tracking effectiveness of policies and actions through targets [see ESRS 2 MDR-T]. [E2-3-23-(d)] → Disclosure of whether and how the target relates to the prevention and control of substances of concern and substances of very high concern With regard to air pollution, none of the facilities managed by Groupe ADP, due to the nature of its activities (energy production and mobility), use or emit substances of concern or very high concern. [E2-3-24] → The ecological thresholds and entity specific allocations taken into consideration when setting pollution-related targets Groupe ADP complies with local regulations on ambient air pollution and implements the necessary measures to meet its regulatory obligations. These objectives correspond to compliance with applicable regulations. The thresholds to be complied with are described in each of these documents vary for each site and may vary depending on how the energy is produced, the surrounding area (presence of housing, sensitive areas, etc.) and the frequency of the measurements required. By way of example, here are the references to the prefectural decrees applicable at Paris-Orly and Paris Charles de Gaulle, which describe the detailed operation of the principles set out above for these airports: CDG: u CTFE: Decree No. IC 20-107; u CTFE Bis: Update of the requirements of AP DAIDD IC 3278 of 21 December 2007. ORLY: u CTP: Decree No. 2023 PREF DCPPAT DCPPAT BUPPE 221 of 20 November 2023; u CTS: Decree of 3 August 2018 relating to combustion plants with a total rated thermal input of equal to or more than 50 MW subject to the authorisation under heading 3110. Allocations of resources (by the Group's constituent entities or through contracts with external experts) are deemed to be in line with the targets set.

[E2-3-25] → The pollution target is mandatory (required by legislation) or voluntary

As indicated in previous sections, the air pollution targets set by Groupe ADP entities are mandatory and required by local regulations. These points are developed, in particular, in chapters: u [E2-1-14] → Policies in place to manage material impacts, risks and opportunities related to pollution [see ESRS 2 MDR-P]; u [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; u [E2-2-AR 15] → Information on site-level action plans (pollution); u [E2-3-22] → [E2] Tracking effectiveness of policies and actions through targets [see ESRS 2 MDR-T]. E2-4 — Evaluation (method and results) of levels of pollutant discharges/emissions by Groupe ADP (including projections) [E2-4-28-(a)] → Air emissions by pollutant The information presented below corresponds to the pollutant flows measured and available at the time this report was written, i.e., the pollutant flows for 2024 at Paris Charles de Gaulle and Paris-Orly. For this first year, data other than for Paris-Charles de Gaulle and Paris-Orly could not be collected in time. Groupe ADP will roll out a dedicated action plan for its international airports so that data can be made available for its 2025 Sustainability Report. In view of the specific features of each hub and the measurements carried out (in particular the frequency of measurement), the Group will publish data made up of actual and estimated data, the details of which will be disclosed for ease of understanding. The data published below corresponds to measurements carried out throughout 2024 through the measurement systems described here [E2-4-30-(b)] → Description of measurement methodologies used (air, water and soil pollution) and in accordance with applicable regulations in [E2-3-25] → The pollution target is mandatory (required by legislation) or voluntary. These are emissions from the power plants at Paris-Charles de Gaulle and Paris-Orly. The pollutants disclosed are those considered necessary for the hubs presented. Any other pollutants mentioned in the regulations are not measured, as they are not considered applicable to the airports in question.
