IMPROVING OUR ENVIRONMENTAL PERFORMANCE

Renewable energy production units at the airports (geothermal plants at Paris-Orly, high-performance heat-cooling pump system and biomass plant at Paris-Charles de Gaulle, heat pump and photovoltaic solar panels at Paris-Le Bourget) covered 9.8% of the internal energy consumption of Aéroports de Paris during the fourth quarter of 2021 (6.2% at end-2020). This figure, up compared to 2020, is explained by: the restarting of the Paris-Charles de Gaulle biomass plant, which encountered operating difficulties in the first quarter of 2020, and whose maintenance and return to service had to be postponed to October 2021, due to the health and social situation; the proper functioning of geothermal energy at Paris-Orly (29 GWh produced in 2021, after significant maintenance in 2020). At Groupe ADP level, renewable energies (biomass, geothermal energy and the purchase of waste heat) made it possible to avoid the emission of approximately 11,300 tonnes of CO 2 in 2021, compared to a scenario using natural gas and electricity from the French national grid. Internationally, the Ankara and Izmir airports operate tri generation plants. Tri-generation is the production of electricity, heat and cold by absorption, using the same machine, through recovery of heat from exhaust gases. This equipment, if properly operated, enables higher overall energy production efficiency than with separate production assets for each energy vector. To go further, Aéroports de Paris is continuing its studies on the potential of two deep geothermal doublets at Paris-Charles de Gaulle airport. The investment in the first of these doublets has been approved. To date, production is scheduled for 2026. At the same time, an investment in a heat pump was approved for Paris-Orly, with provisional commissioning in 2024. Contribute to the decarbonisation of air transport Policy and objectives As part of the “Airports for Trust” charter, 23 of the Group’s platforms are committed - this is one of the four strategic pillars of this charter - to actively participating in the environmental transition in the aviation sector and to proposing airside greening solutions. 2021 achievements and results For Aéroports de Paris, this resulted in 2021: ◆ participation, in the form of support, in various projects for the production of sustainable aeronautical fuels (CAD) as part of a call for projects led by ADEME to develop CAD production channels (pursuant to the Call for Expressions of Interest in which ADP participated via five consortia in the summer of 2020); ◆ the completion in May 2021 of a CAD demonstration flight together with Air France, Airbus and TOTAL between CDG and Montreal: seven tonnes of CAD produced from used cooking oils representing 16% of the onboard fuel and a 15% reduction in CO 2 emissions; ◆ continuous use of sustainable aviation fuel at Paris-Le Bourget Airport since June 2021;

◆ the signing in the spring of 2021, between Groupe ADP, Airbus and Air Liquide, of a cooperation agreement which aims to define the logistics plan most suited to airport challenges across the entire hydrogen value chain and to prepare the adaptation of airport infrastructure to the industrial process of hydrogen for aviation; ◆ the organisation of the H2 Hub Airport call for Expressions of Interest (see paragraph “Innovation for the environmental transition”); ◆ the selection of ground-handling assistants at Paris-Charles and Paris-Orly on the basis, among other things, of a criterion for the greening of their vehicles heavily weighted during the consultation. The selection process made it possible to define the objective of achieving 75% clean machines by 2025 for limited services (related to baggage handling and aircraft movements). Groupe ADP also announced a target of 90% clean vehicles by 2030 for limited services. Acting for air quality Policy and objectives Groupe ADP has implemented an ambitious policy to reduce the emissions of atmospheric pollutants linked to its activities and facilities, and its energy production units in particular. This policy is based on three main areas of work: monitoring, ◆ 30% clean vehicles 1 in its light vehicle fleet 2 reduce emissions from other vehicles and develop electric vehicle charging stations at its airports; ◆ continue the mobility plan and actively contribute to inter company mobility plans for Paris-Charles de Gaulle, Paris-Orly and Paris-Le Bourget airports; ◆ limit and reduce the emissions of aircraft on the ground (taxiing and parking) and of ground handling vehicles (GSE) 3 ; ◆ reduce the emissions associated with airport access and internal circulation. To these objectives, driven by the environmental and energy policy, can be added the commitment made by Aéroports de Paris during the National Conference on Air Transport ( Assises nationales du transport aérien ) in 2018, to strengthen its partnership with Airparif, in particular to exchange monitoring data, and its collaboration in the next measurement campaigns. Aéroports de Paris also took part in the drafting of the 2018-2025 atmosphere protection plan (AAP) for the Paris urban area which defines measures to improve air quality in the Paris region. Aéroports de Paris performs actions to monitor air quality. Accredited by COFRAC, the French Accreditation Committee, its laboratory operates four air quality measuring stations at the Paris-Orly and Paris-Charles de Gaulle airports. It keeps an inventory of the emissions from aircraft, thermal power plants and road transport generated by airport activities. It conducts studies of the indoor air quality in terminals, car parks and technical buildings. It continuously measures levels of nitrogen dioxide (NO 2 ) and nitric oxide (NO), particle levels (PM 10 and PM 2.5) and ultra-fine particles. communication and reduction of emissions. Aéroports de Paris set four objectives for 2021:

1 Electric or hybrid vehicles. 2 City cars, executive vehicles and vans. 3 Ground Support Equipment, ground-handling vehicles.
