SOC I AL , ENV I RONMENTAL AND SOC I ETAL RESPONS I B I L I TY I NFORMAT I ON 4 METHODOLOGICAL NOTE ON SOCIAL, SOCIETAL AND ENVIRONMENTAL REPORTING

This choice is based on the fact that (1) only Izmir and Ankara airports have significant traffic, (2) ADP’s operational levers are lower on the other airports and (3) Scope 3 emissions are not available, when airports have not achieved ACA3 certification. The scope of CO 2 emissions of scope 3 presented in the Chapters “Axis 1: Move towards operations with zero environmental impact” and “Axis 2: Actively participate in the environmental transition in the aviation sector” covers – in line with the GHG Protocol: ◆ external CO 2 emissions of controlled airport platforms (the three Paris airports: CDG, Orly, LBG, two TAV Airport platforms: Izmir, Ankara – and one AIG airport) linked to aircraft operations – half cruise (new, in the case of airports ACA4 or ACA4+ certified), Cycle LTO, ground-handling vehicles (GSE), aircraft auxiliary power units (APU), upstream energy, passenger and employee access, and all employees’ business travel, to the treatment of internal waste and consumption of third-party buildings; ◆ as well as the Scope 1 and 2 emissions of subsidiaries over which Aéroports de Paris does not have operational control. As scope 3 for year N was not available at the end of January N+1, it is that of year N-1 that is indicated. Notes: (1) The scope 3 of certain majority-owned subsidiaries (Hub One, Hologarde) is not included here because it is not significant for the scope 3 of the airport platforms due to the size and nature of the activities of these subsidiaries; (2) As the methodology for the consolidation of subsidiaries changed in 2022 as part of our Non-Financial Performance Statement, the group’s consolidated ACA emissions balance sheet will take this change into account for the 2022 financial year and will be in the NFPS 2023.

◆ Belgium: Liège Airport 26%; ◆ Chile: Nuevo Pudahuel airport in Santiago de Chile 45%; ◆ Croatia (2): Zagreb airport 21%; ◆ 100% consolidated: Groupe ADP’s IT subsidiary: HubOne (2). With regard to the assessment of carbon emissions, the group has two financial years with two different deadlines. The first is done as part of the NFPS and the second consolidates the group’s ACA data as well as the assessments of the CO 2 emissions of other non-airport subsidiaries. The breakdown of carbon emissions for 2021 takes into account our previous reporting methodology. Thus, in 2021, only the Izmir and Ankara platforms were considered at 100% for TAV. This methodology, which applied until 2021, is based on the following principle: The internal emissions (scopes 1 and 2) of the entities majority owned by ADP – consolidated within the financial scope – are included in the scope 1 and 2 of Groupe ADP. Internal emissions (scopes 1 and 2) of non-consolidated assets ( i.e. assets without operational control) are recognised in scope 3 of Groupe ADP in proportion to Groupe ADP’s rate of financial participation in these entities. Groupe ADP’s scope 3 includes scope 3 emissions from entities majority-owned by ADP and scopes 1 and 2 emissions from non-controlled assets, in proportion to Groupe ADP’s financial participation rate. Case of TAV Airports As the ACA assessment is an exercise carried out during year N for year N-1, the availability of data leads the Group to publish this consolidated ACA balance sheet with a one-year delay. Thus, for the year 2022, the 2021 methodology was used to carry out the Group assessment. For this year 2022, which reports on the 2021 data, only the airports of Izmir and Ankara are considered as controlled as part of the carbon emissions assessment. The indicators published by Groupe ADP are intended to report, with complete transparency, the Group’s annual results with respect to social responsibility and, if applicable, stakeholder expectations. The indicators are chosen based on the social, societal and environmental impact of Group company activity and the risks associated with the Company’s strategic challenges. The data selected are based on a common set of criteria: ◆ to the commitments and corporate social responsibility policy of Groupe ADP; ◆ to the regulatory obligations set by the French government; ◆ to the Group’s performance and impact in relation to the key challenges;

4.7.3 RELEVANCE AND CHOICE OF INDICATORS, CHANGE IN SCOPE

◆ to some of the group’s environmental certifications ( e.g. ACA, ISO 14001 and 50001). The social indicators published by Aéroports de Paris are based on three levels of indicators: ◆ the themes of article L. 225-102-1 of the French Commercial Code; ◆ the social reporting indicators set forth in French law; ◆ the specific indicators of the Group’s human resources policy. The complementary nature of these three levels of indicators makes it possible to measure the results of the human resources policy and the Group’s commitments on social matters.
