4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

The emission factors used come from ADEME's footprint database and are updated annually. Scope 2 – location-based and market-based Groupe ADP's Scope 2 covers GHG emissions linked to our energy purchases and consumption, whether electricity, heat, cold or steam. These emissions are calculated using two methods: location-based, based on average network emission factors, and market-based, taking into account the specific features of supply contracts and associated emission factors where available. The electricity emission factors used for Scope 2 calculations come from: u for hubs in the Paris region, the production mix published annually by the EEX; u for international hubs, production mixes by country published by the IRENA. Scope 3 u Category 1 - Purchased goods and services: This category includes emissions linked to operational expenditure on assets (OpEx). Emissions are calculated according to the expenditure-based method described by the GHG Protocol, using monetary emission factors. The amounts used correspond to expenditure on goods and services (service contracts, maintenance contracts, purchases of small supplies, etc.). Each euro spent is associated with a group of goods derived from the purchasing segmentation built up internally. Each commodity group is associated with a purchasing group and an emission factor specific to that group. The monetary emission factors used to calculate emissions come from ADEME's footprint database for French assets, and from the Exiobase database for significant foreign assets. u Category 2 - Capital goods: This category includes emissions related to capital expenditure (CapEx). For Paris airports, they are estimated using a specialised tool that combines the amounts of incoming goods with physical data. For the other significant assets, the calculation methodology is similar to that used to calculate Category 1 emissions. u Category 3 - Fuel and energy-related activities (not included in Scopes 1 and 2): This category includes upstream emissions from fuels and energy purchased and consumed by the assets. Emissions are calculated using the "average-data" method described by the GHG Protocol. The upstream emission factors used come from ADEME's footprint database. u Category 5 - Waste generated in operations: This category includes emissions generated by the transport and treatment of our non-hazardous waste (NHW) and special industrial waste (SIW), as well as emissions related to wastewater treatment for the Skopje hub. Emissions are calculated using the "average-data" method described by the GHG Protocol. For the significant French assets and for the Amman hub, the volumes of non-hazardous waste and special industrial waste generated by the activities are listed for each hub. Thanks to the waste tracking system, we know how much of our waste is recycled, incinerated

and sent to landfills. These data are associated with the emission factors for waste in ADEME's footprint database. Skopje Airport calculates the emissions linked to the treatment of its wastewater on site by taking into account the volume of water treated. Emissions from other significant assets are estimated pro rata to emissions from Amman Airport. u Category 6 - Business travel: This category includes emissions linked to business travel by employees from significant assets. Emissions are calculated using the "distance-based" method described by the GHG Protocol. For the French workforce, information on the various business trips is used to determine the means of transport and the average distance travelled by each employee on each mission. A distinction is made between air, rail and car travel. These distances travelled are associated with the emission factors for the various means of transport available in ADEME's footprint database. The Amman, Milas-Bodrum, Izmir, Ankara and Alanya-Gazipasa hubs calculate these emissions based on employee travel data during their business trips. Emissions from other significant assets are estimated in proportion to emissions from Amman Airport. u Category 7 - Employee commuting: This category includes emissions linked to employee travel to and from work. Emissions are calculated using the "distance-based" method described by the GHG Protocol. For French employees, the home/work distance, modal split and days worked on site are calculated using human resources data. These data are linked to the emission factors for transport and vehicles in ADEME's footprint database. The hubs in Amman, Milas-Bodrum, Izmir, Ankara and Alanya-Gazipasa calculate these emissions using data from the hubs' human resources. Emissions from other significant assets are estimated in proportion to emissions from Amman Airport. u Category 11 - Use of sold products: This category includes emissions generated by the use of products and services sold by the assets. The 'services sold' by airport operators are the use of infrastructure and services by third-party customers and users (runways, roads, car parks, etc.). For significant assets, the following sources of emissions are taken into account: u the operation of aircraft by airlines: –landing and take-off cycle (LTO), corresponding to aircraft movements below 3,000 ft, – APU (Auxiliary Power Unit), used to supply power to parked aircraft, – “departure cruise” emissions from aircraft, u Ground Service Equipment (GSE) and vehicles used by ground handling staff, u access to our hubs for third parties (passengers, airport community employees). The emissions in this category are calculated in the "use phase" (Tank to wheel) . The emission factors used (fuels, transport, paraffin) come from ADEME's footprint database.
