4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

An important adaptation measure already in place concerns the corporate governance structure of Aéroports de Paris SA. The Board of Directors helps define a clear climate ambition and the current governance of the Company is able to implement them through rapid and mature decision making processes. This strengthens the ability of managers to respond to the challenges posed by climate risks. In 2023, a reorganisation validated the creation of a Deputy Chief Executive Officer’s Cabinet in charge of Sustainable Development and Projects: this function embodies, at the highest level of the Company, the consistency between the management of development and investment projects, and the challenges of environmental and climate transition. The study on the resilience of the Paris region hubs to climate change also shows the implementation of significant adaptation measures. For example: u with regard to the risk of flooding (qualified as moderate in the gross risk analysis) and water stress, rainwater management policies have been introduced, including both infiltration management and water reuse. Adjustments in the design of infrastructures are made to take into account climate change (for example infiltration at the plot, resizing of the drainage pipes during the repair of runway 4 at Paris-Charles de Gaulle, or of the retention basin of the Golf aircraft parking areas at Paris-Orly); u regarding the anticipation of climatic hazards related to heat, Groupe ADP has applied, for several years, strict French standards at its hubs in the Paris region, thus ensuring the strong future resilience of the terminals. In addition, sensors have been installed at runway thresholds to better monitor the behaviour of infrastructures and better understand strategies for adapting to climate hazards; u in addition, the study highlighted numerous mitigation measures (and therefore the reduction of GHG emissions) making it possible to limit, at the global level, the consequences of global warming. This is the case, for example, for actions related to the decarbonisation of the energy mix of airports, made possible by the deployment of decarbonised or low-carbon heat/cold production assets (reinforcement of geothermal energy, increase in heat pump capacity, use of biomass boilers) and the implementation of contractual mechanisms guaranteeing the purchase of low-carbon electricity (Power Purchase Agreement, guarantees the renewable origin of electricity). The analysis also highlights opportunities to strengthen the resilience of certain critical assets in the face of future extreme climate scenarios.

For example, when purchasing the most vulnerable airport equipment, it could be considered to systematically include specifications that take into account pessimistic scenarios in terms of climate change. This could make it possible to limit the occurrences of corrective maintenance and replacement of this equipment. By way of illustration, for equipment such as the “X-rays” of filtering inspection stations or gateways, the consideration of criteria such as a higher operating temperature range or better resistance to a higher constant humidity rate should lead to a reduction in obsolescence and an improved availability rate. Recognition of the challenges associated with prolonged periods of extreme heat could result in consideration of various solutions in terms of buildings and infrastructure as well as energy management, from thermal rehabilitation to the installation of brise-soleil (sunshade), through to the exploration of alternative solutions for bituminous coatings and the implementation of revegetation and soil waterproofing removal practices. In conclusion, the preliminary results for 2023 attest to Groupe ADP’s proactivity in making the Paris region’s airports resilient to climate risk. The completed and future actions aim to transform these challenges into opportunities, strengthening the sustainability, resilience and operational performance of airport infrastructures. Analysis of the risks and opportunities of the transition to a low-carbon economy 39 risks and opportunities have been identified. The analysis shows that the main challenges of the climate transition are related to the loss of attractiveness of our portfolio (ageing infrastructure, reasoned development, etc.), the increase in energy costs and insufficient quantities of low-carbon/ decarbonised energy (for the production of sustainable aviation fuels for air transport, for example) and with an environmental transition schedule that could be subject to uncertainties. To meet these challenges, the Group has the opportunity to promote a new airport model and alternative solutions in its business model (the airport becomes an energy and multimodal hub). Groupe ADP takes into account its dependencies and the main risks specific to its sector in order to strive for sustainable activities.
