SOC I AL , ENV I RONMENTAL AND SOC I ETAL RESPONS I B I L I TY I NFORMAT I ON 4 IMPROVING OUR ENVIRONMENTAL PERFORMANCE

◆ the replacement of two gas boilers with more efficient and less polluting models; ◆ the replacement of traditional lighting systems with more energy-efficient LEDs; ◆ the replacement of old HVAC (heating, ventilation and air conditioning) equipment motors with high-performance motors; ◆ the installation of dual-flow air conditioning units; ◆ the investment in new energy-efficient wave concept baggage sorting technologies; ◆ the replacement of thermal and cooling energy production assets with high-performance technologies. In addition, Aéroports de Paris is engaged in the construction of new high-performance buildings. For example, the Junction building (ORY3) which links the former Orly Sud and Orly Ouest terminals to create the single terminal on the Paris-Orly platform, which was built in 2018 and 2019, is HQE Excellent-certified. In the fourth quarter of 2021, Aéroports de Paris thus improved its energy efficiency by 29% compared to 2015 (the reference year). This improvement was 28.4% in 2020. This was mainly due to lower passenger traffic, which led to a reduction in energy requirements, achieved thanks to the actions undertaken in the field by the operational teams (shutdown of some equipment, etc.) and the closure of certain terminals due to the collapse of air traffic 1 . Developing renewable energies Policy and objectives At its Paris airports, Aéroports de Paris set itself the target of meeting 10% of its final energy consumption requirements 2 using renewable sources and achieving a 100% target for green electricity purchases in 2021. This objective was based on two factors: ◆ the development of its own land of energy production units from renewable sources (biomass boilers, geothermal energy, photovoltaic solar panels, heat-cooler pumps); ◆ the purchase of renewable energy (green electricity with guarantees of origin, an additional Power Purchase Agreement, and purchases of waste heat). 2021 achievements and results In this context, Aéroports de Paris subscribed to an offer of electricity from renewable sources that committed its supplier to delivering 100% renewable electricity to its Paris airports in 2021 (50% in 2015). The energy company provides third-party certification that the 100% quota was produced by hydroelectric dams, wind farms or solar farms. The corporate Power Purchase Agreement (contract for the direct supply from a producer of renewable energy) signed in early 2020 by Aéroports de Paris enabled the selected developer (Urbasolar) to continue the development of the three additional photovoltaic solar parks dedicated to Aéroports de Paris and for which Groupe ADP has committed to purchase the entire electricity production for 21 years. To date, commissioning is scheduled for 2022 or 2023 depending on the park. The three parks will produce around 45 GWh/year, i.e. 10% of the pre-Covid electricity consumption of the Paris platforms.

The external CO 2 emissions (scope 3) of these six airports were estimated as part of the Airport Carbon Accreditation programme to be around 1,058,610 tonnes in 2020. For aircraft-related emissions, this estimate included the entire LTO cycle (landing, taxiing, take-off), as well as parking emissions. A significant decrease compared to 2019 was observed for scope 3, which is more directly correlated to traffic. Aéroports de Paris operates energy production units with an installed capacity in excess of 20 MW and is therefore subject to Directive 2003/87/EC of 13 October 2003 on greenhouse gas emissions allowances for the Paris-Charles de Gaulle and Paris-Orly Airports. The installed capacity at Paris-Le Bourget was reduced to below the 20 MW threshold in 2020. Under the National allocation plan for greenhouse gas emission allowances, annual allowances are allocated to Aéroports de Paris and its CO 2 emissions are carefully monitored. Thanks to the improvement in its energy efficiency and the investments made in low carbon thermal production equipment (biomass, geothermal, photovoltaic), the balance of quotas of the plants operated by Aéroports de Paris is positive, and Aéroports de Paris does not buy on the markets. In accordance with article L. 229-25 of the French Environmental Code, Aéroports de Paris regularly reports on its greenhouse gas emissions. CO 2 emissions data of its power plants are audited annually by a third party as part of the PNAQ. Aiming for energy efficiency Policy and objectives Another commitment by Aéroports de Paris in the fight against climate change is to improve its energy efficiency by 1.5% per year over the 2016-2021 period (a total of 8.5% over five years). These initiatives are organised around two axes: energy optimisation for operations and maintenance, and the construction of new high performance buildings and the improvement of the performance of existing buildings and machinery. In addition, the “life cycle” approach and an energy performance criterion are included in the ratings of tenders in the purchasing process. An internal CSR-environment purchasing procedure was also deployed in 2018 to integrate the life cycle approach into the purchasing process, in accordance with the requirements of the 2015 version of ISO 14001. This approach takes environmental impacts into account at each stage of the life cycle for the different purchasing categories. In addition, the Purchasing Department and the Sustainable Development and Public Affairs Department have targeted the highest-risk purchasing families by their impact on energy consumption and raised awareness among specifiers and buyers in order to include a specific criterion based on energy performance. A guide to identifying relevant criteria for “high energy-consumer” segments has been introduced. For these segments, the energy performance criterion is included in consultations during offer rating and is separate from the CSR criterion. 2021 achievements and results In 2021, energy-saving programmes for existing buildings continued with, in particular: ◆ remote electricity meter readings to allow better monitoring of consumption and detect excesses;

1 The corresponding surface areas are maintained in the calculation of the energy performance indicator, due to the residual energy consumption in these buildings. 2 Renewable energy production at the three Paris airports/final internal energy consumption.
