SUSTAINABILITY REPORT 4 ENVIRONMENTAL MATTERS

Lever 2 – Developing low-carbon heat The Paris-Charles de Gaulle hub has an ambitious plan to develop renewable thermal energy sources: u the two wood-fired boilers commissioned in 2012 provide 25% of the airport's annual heat production for heating and domestic hot water. They run on untreated wood residues, mainly from sustainably managed forests close to the airport. The two wood-fired boilers that make up the boiler house have a production capacity of 70,000 kWh; u in 2026, a deep geothermal power plant will be commissioned to produce 80 GWh of renewable heat. The total share of renewable energy at Paris-Charles de Gaulle should reach more than 50% of heat production by 2027; u consideration is currently being given to the complete decarbonisation of natural gas consumption to achieve net-zero emissions by 2035, with the potential development of a new decarbonised heat production asset and the purchase of biogas Guarantees of Origin. The challenges of lowering the emissions of the surrounding areas are taken into account in achieving this target (connection to heating networks, shared development of renewable energy production assets, etc.). The Paris-Orly hub is committed to the environmental transition with the development of renewable thermal energy sources: u a power plant linked to a deep geothermal well was commissioned in 2011 and now covers a third of the heating needs of the airport's terminals and infrastructure; u in winter, this heat production is supplemented by heat recovery from the Rungis incineration plant and the airport's gas-fired power station. The total share of renewable and recovered energy at Paris-Orly reached 82% of heat production in 2024; u in 2024, a heat pump will optimise the existing geothermal system; u a study is in progress to install a methanisation unit to recover bio-waste from Rungis International Market and Paris-Orly airport, in order to provide a low-carbon heating solution, in conjunction with the Régie personnalisée pour la Valorisation et l'Exploitation des Déchets de la région de Rungis (RIVED) and the surrounding areas. This biogas will be used to top up gas consumption and achieve net-zero emissions. The decarbonisation of heat from Paris-Le Bourget is linked to its region: u since October 2023, major works have been in progress between the municipalities of Le Bourget and Dugny, with the aim of connecting the airport hub to the heating network of these communes in Seine-Saint-Denis, which are powered by geothermal energy. Connection to this heating network is planned for 2025, which will provide a heating network that is 90% carbon-free; u biogas Guarantees of Origin will be purchased to supplement gas consumption and achieve net-zero emissions. Amman airport is looking at ways of reducing the emissions from its boilers: u 52% of the Scope 1 emissions come from boilers. A study is in progress to replace diesel with local natural gas, which would cut emissions by 15% compared to 2022.

In order to manage this ambition to control energy consumption, Aéroports de Paris SA has defined two energy performance indicators for its Parisian hubs:

u an energy performance indicator for electricity; u an energy performance indicator for heating.

To set up and validate the relevance of these two indicators, a correlation analysis with influential factors (Unified Degree Day (UDD) hot, UDD cold, occupied surface area, number of passengers) was carried out in 2019. The main influencing factors are: u for heating consumption: hot UDD, surface areas and number of passengers; u for electricity consumption: hot UDD, cold UDD, surfaces and the number of passengers. Every quarter, heating and electricity consumption are adjusted for the influential factors identified. This corrected energy consumption is then compared with 2019 to measure the level of internal energy performance and compare the energy performance of the Parisian hubs on a comparable scope. Given the increase in energy prices and the geopolitical context, 2022 was mainly marked by the implementation of an energy sobriety plan and a demand response plan at the request of the French government for the Parisian hubs. As a responsible company, Aéroports de Paris SA has signed the Ecowatt charter (RTE) and the Ecogaz charter (GRTgaz) indicating its desire to implement an energy sobriety plan applicable over time and a demand response plan to reduce its electricity consumption during days of stress on the electricity network. The main measures implemented are: u reduce heating to 19°C in the offices/terminals and to 16°C in places with low traffic; u avoid auxiliary electric heaters; u keep doors and windows closed to avoid heat loss; u in accordance with regulations, air conditioning at a temperature of 26°C during the summer; u reduce and optimise lighting; u optimise air renewal according to the zones. Since 2012, Amman airport has significantly reduced its carbon footprint on Scopes 1 & 2 by improving energy efficiency, in particular through the installation of ECMs (Electronically Commutated Motors). By 2022, these engines will have reduced Amman Airport's carbon footprint by 50% since 2012. An energy audit to be conducted in 2024 will define the action plan for achieving the decarbonisation trajectory targets. TAV Airports aims to significantly improve the energy efficiency of the airport hubs in Ankara, İzmir Adnan, Menderes, Antalya, and Enfidha, by: u implementing advanced energy management systems; u incorporating green construction principles into new builds and renovations to improve the energy efficiency of buildings; u deploying an energy management system that tracks energy consumption in real time; u renovating old infrastructures to improve their energy efficiency.
