4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

[E4-ESRS 2 IRO-1-17-(c)] → Disclosure of identified and assessed transition and physical risks and opportunities related to biodiversity and ecosystems, and how they were identified The Impacts and Dependencies study identified the risks and opportunities generated by each of Groupe ADP's business lines. Thus, among the main risks faced by Groupe ADP, the following are detailed in this chapter: the risks of land stabilisation and erosion, the risks associated with land use and changes in land use, the transport of exotic species, dependence on ecosystem services, and the supply of wood and natural fibres. The relevant risks identified are: 1. Supply risks Supply risks linked to the increasing scarcity of wood, natural fibre and other crop-based materials as a result of climate change: fires, health crises, overshoot (transition risk), etc. In its role as an infrastructure developer (builder), Groupe ADP is an indirect purchaser of wood, wood based materials and natural fibres, for example for building insulation, even if these can be substituted. In addition, the decarbonisation of the aviation sector, particularly for biofuel production, and the increased risk of fires (at global level) generated by climate change may exert additional pressure on the availability of these resources. 2. Regulatory risks Regulatory risks relating to changes in land use and the footprint of its activities (transition risks) As an airport operator and manager of natural and man made areas, Groupe ADP operates thousands of hectares of land made up of built-up areas, man-made areas and green areas made up of natural and semi natural environments, some of which may be recognised nationally or regionally for their ecological value in terms of biodiversity. As a result, there is a risk that regulations could be tightened up on the artificial development of land and the need to obtain environmental permits for construction. 3. Operating risks Operating risks relating to changes in land use and the footprint of its activities (physical and transitional risks) Urban sprawl around hubs also makes them more attractive to certain species and increases the risk of animals colliding with aircraft. Air traffic can be disrupted by changes to the natural environment on and near the hubs, which can generate physical, safety, traffic, insurance and personal risks and additional costs.

The decarbonisation of activities in the airport sector could eventually result in a change in the use of land that is currently "natural" (green areas), particularly with a view to installing renewable energy assets such as photovoltaic panels, if the issue of compatibility between photovoltaic solar energy and biodiversity is not carefully addressed. Operating risks associated with land stabilisation and erosion (physical and transitional risks) The pressure exerted on the soil by the construction and maintenance of infrastructure, buildings and other artificial areas at airport hubs, as well as the pressure exerted indirectly by the Group's value chain, in particular with regard to food production, contribute to the disruption of geochemical cycles (in particular water), plant cover and root networks. This disruption weakens soil stability and increases the risk of erosion, landslides, run-off and flooding. This disruption could cause damage to hub infrastructure and limit the supply capacity of in-terminal restaurants and shops, resulting in additional costs or loss of revenue. Operating risks linked to the spread of exotic species with or without an invasive effect (physical risks and transition risks) As a holder and manager of green species, Groupe ADP faces the risk of exotic plant species that can disrupt its activities and generate additional operating costs. Climate change is disrupting animal species, particularly migratory birds, and these changes in movement require increased vigilance on the part of safety teams to prevent risks related to wildlife. 4. Reputational risks Reputational and operational risks related to climate change (physical risks and transition risks) Groupe ADP is committed to decarbonising its activities in the short, medium and long term (see ESRS E1). However, there is a reputational risk in implementing projects aimed at achieving the Group's climate commitments without taking sufficient account of parallel issues that could cause additional pressure on living organisms through land artificialisation, over exploitation of resources, pollution or the displacement of exotic species. Strong interactions have been identified in the following areas: ground-mounted photovoltaic installations, biofuel supplies and carbon offset projects. Reputational risks linked to the spread of exotic species with or without an invasive effect (physical risks and transition risks) As transit points for passengers and goods, airports are a geographical link exposed to voluntary or involuntary traffic linked to the transport of exotic species. Groupe ADP’s Scope 3 1 , in particular customs services and cargo companies and airlines, is particularly concerned by the management of voluntary wildlife trafficking and the involuntary transport of exotic species.

1 Here, the notion of scope is understood as defined by the Corporate Biodiversity Footprint methodology. Scope 1 refers to the scope of the organisation's direct operations or activities, while Scope 3 covers all the indirect impacts along the company's value chain, including suppliers, final products and subsequent uses, as well as the end-of-life of products.
