SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

The methodologies used to calculate these sources are detailed here: u For significant French assets, aircraft emissions are calculated on the basis of consolidated data for each flight (type of aircraft, destination, type of engine) and using the calculation methodology specified by the ICAO in document ICAO 9889 Second Edition 2020; u LTO cycle emissions are calculated using the paraffin consumption for each phase of the cycle and according to the type of engine and the duration of each phase as defined by the ICAO. u APU emissions are calculated on the basis of APU paraffin consumption. This is determined per aircraft, per engine type and according to the average APU operating time of the aircraft on arrival/departure. The time data (time of use of the APU) come from the study carried out by the ACNUSA in 2020 offering a statistical analysis of the administrative information reports drawn up between 2014 and 2019 during the checks carried out on the time of use of APUs; u cruise departure emissions 1 are calculated for each aircraft departing from the hubs and according to engine type. We calculate emissions for 100% of the route of all aircraft departing from our hubs. To do this, we use the great circle distance between airports and apply consumption models according to aircraft type. This method better reflects the effects of Groupe ADP's policy on the development of the use of SAF (see section 2.1.3. Development of new energy sources); u for Amman Airport, Category 11 emissions are calculated on the basis of aircraft arrival/departure data provided by the airlines. Aircraft emissions from other significant assets are estimated using paraffin consumption data from the hubs. Groupe ADP's ultimate aim is to calculate aircraft emissions directly using airline fuel consumption data. u Ground handling emissions at Paris-Charles de Gaulle and Paris-Orly are calculated based on fuel consumption data provided by ground handling service providers as part of a data feed carried out in 2018. The 2024 data are calculated on a pro rata basis from the 2018 data, based on the number of aircraft movements per airport. Fuel consumption data for Paris-Le Bourget is obtained directly from the Fixed Base Operator (FBO). Amman's ground handling emissions are calculated using a correlation with the number of aircraft movements in the year. Emissions from other significant assets are estimated pro rata to emissions from Amman Airport. u Emissions from access by passengers and non-ADP employees at Paris region hubs are determined via an annual passenger survey and a socio-economic study carried out in 2023. We take into account the number of origin/destination passengers (excluding connections) and employees arriving at and departing from our hubs, and use these surveys to qualify their means of transport and estimate the average distance travelled. Emissions from this source in Amman are calculated by taking into

account the number of aircraft movements per year. Emissions from other significant assets are estimated pro rata to emissions from Amman Airport. u Category 13 - Downstream leased assets: This category includes emissions related to products and services leased to third parties. Emissions are calculated using the "average-based" method described by the GHG Protocol. For significant assets in France, these are emissions linked to the energy consumption of Groupe ADP property leased to third parties. Lease agreements are provided for electricity. Emissions are calculated in accordance with the recommendations of the GHG Protocol, using the average data method and a tank-to-wheel methodology. We account for the quantity of electricity sold to our tenants, and calculate the emissions linked to the proportion of electricity not covered by guarantees of origin if this is the case at our airports. We then correlate this remaining electricity with the most recent French residual mix emission factor provided by the European Energy Exchange (EEX) and Powernext each year. Enfidha, Milas Bodrum, Izmir and Ankara airports also rent plots and sell electricity. These emissions are calculated on a pro rata basis for Paris-Orly airport. The other significant assets do not lease any plots of land and therefore do not report anything in this category. u Category 15 - Investments: This category includes emissions resulting from Groupe ADP's investment in assets over which it has no financial or operational control. Only equity investments in airport hubs are included here. In fact, internal emissions (Scopes 1 and 2) from non airport and non-controlled assets represent a very small proportion of internal emissions from non-controlled airport hubs. Emissions from these non-controlled hubs are included in the GHG assessment in proportion to the stake held by ADP SA (parent company of Groupe ADP) in the companies that own the airports. In 2024, the non controlled assets estimated to be significant in terms of their emissions are the following airport hubs: u Liège Airport SA (26% holding); u Sociedad Concesionaria Nuevo Pudahuel SA (SCNP) (45% holding). u Medunarodna zracna Luka Zagreb d.d (MZLZ) (21% holding): u GMR Airports Limited (45.7% holding); u Ravinala Airports (35% holding). u TAV Antalya and TAV Medine (23% and 12% respectively). Scopes 1 and 2 emissions are calculated on the basis of asset activity data, with actual data for the first three quarters and an estimate for the fourth quarter, for the following assets: Liège Airport SA, Sociedad Concesionaria Nuevo Pudahel SA, MZLZ, Ravinala Airports and GMR's Delhi and Hyderabad Airports. Emissions from other hubs (GMR's Medan, Cebu and Goa, TAV Airports' Medine) are estimated, as they have not yet provided their activity data.

1 Emissions from aircraft in flight can be calculated using two different methods: the "half-cruise" and the "cruise-departure” methods. The "half-cruise" method takes into account 50% of the emissions of the total route of aircraft in flight (>3,000 feet) departing from and arriving at the airport in question. On the other hand, the "cruise-departure" method, takes into account 100% of the emissions from the aircraft's flight path, but only on departure from the airport. These two methods are equivalent and authorised by the ACA.
