4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

[E1-3-AR 19-(d)] → Type of adaptation solution The adaptation solutions currently being implemented fall into two categories: u “hard” measures, referring to engineering, technological and nature-based measures; u and "soft" measures, referring to organisational, behavioural and cultural measures. Details of the types of measures are set out in the table above ([E1-3-28] → Actions and resources related to climate change mitigation and adaptation [see ESRS 2 MDR-A]). [E1-3-AR 21] → Explanation of the extent to which the ability to implement an action depends on the availability and allocation of resources By the end of 2025, Groupe ADP plans to produce a detailed, budgeted action plan for adapting its Paris hubs to 4.2.1.2 Climate change mitigation The fight against climate change was reaffirmed as a priority for Groupe ADP by Chairman Augustin de Romanet at the 5 th Congress of the Union of French and Francophone Airports held in Montrouge in 2023 in the presence of the French Minister Delegate for Transport. Climate change mitigation is managed through Groupe ADP's climate transition plans. This is based on the 2025 Pioneers strategic roadmap adopted in 2022 and the Group's 2025 Pioneers for Trust CSR policy. E1-4 — Targets for climate change mitigation Groupe ADP's climate targets are consistent with the commitments made in its strategic roadmap and CSR policy. These are centred on airport hubs, which generate the majority of the Group's greenhouse gas emissions (96%, see section E1-6-AR 39-(b)). Three of the four areas of environmental policy are directly related to the climate: u move towards operations with zero environmental impact; u actively participate in the environmental transition in the aviation sector; u reduce the environmental footprint of airport activity planning and development projects. These areas are made up of climate commitments, broken down into short-, medium- and long-term decarbonisation targets for internal and external emissions from airport hubs. Groupe ADP has set decarbonisation targets, encompassing both internal and external sources of emissions, in several reference frameworks: u SBTi (Science Based Target initiative) targets for the Group's Paris region hubs; u ACA (Airport Carbon Accreditation) targets defined at the airport hub level (see the table of airports that have validated an ACA net-zero target).

climate change. This plan will include priorities for action to make existing infrastructures resilient in the face of identified climate hazards, such as heat waves or flooding. It will be completed by: u a business continuity plan to guarantee the security and operation of critical services, even in a crisis situation; u construction guides for new buildings, infrastructures and structures, incorporating resilience principles right from the design stage. In order to ensure the availability of resources, this plan will not be an isolated aspect, but an essential component of Groupe ADP's overall strategy. Finally, Groupe ADP is aware that implementing adaptation solutions will require investment, the cost of which will vary depending on the warming trajectory chosen (TRACC, SSP2-4.5 or SSP5-8.5). Section E1-4 is structured according to these two types of decarbonisation targets. These objectives are each detailed in section E1-1 and in section 2.3.1 “Development of new energy sources”. These decarbonisation objectives are also based on targets for the use of renewable energy sources, an important issue for Groupe ADP. The establishment of a single overall greenhouse gas emissions reduction target, aligned with the scope as described by the CSRD, combining the individual targets for each airport, is currently in progress and planned for 2027. In addition to these targets, we aim to involve the entire value chain in making Paris Region airports "carbon neutral". The decarbonisation ambitions of Groupe ADP and its airports are characterised throughout the chapter by the terms neutrality or net-zero (net-zero emissions). These two terms are used with reference to the definition given by the ISO 14068 standard and the ISO IWA 42:2022 guide: once GHG emissions have been reduced at source, carbon neutrality authorises offsetting (with no limit on quantity) through avoidance and/or sequestration projects, whereas for net-zero emissions, offsetting of residual emissions is authorised only through sequestration methods and may not exceed 10% of emissions in a reference year. In this sense, neutrality is seen as a step on the road to achieving Net Zero. These goals of neutrality, on the one hand, and Net Zero, on the other, are each characterised by targets for reducing GHG emissions in relation to a reference year (see section E1-4-34). Moreover, the use of carbon credits in no way hinders the achievement of these GHG reduction targets; they are complementary. The credibility and integrity of the carbon credits used are based on recognised quality standards (see section E1-7-61).
