2.5.2.2 Action plan
In response to the increasing scarcity of water resources, especially in areas of water stress, VINCI’s action plan covers a range of initiatives:
- measuring water withdrawals and detecting leaks;
- adapting infrastructure to reduce its water needs and determining degraded modes of operation in the event of a shortage;
- creating closed-loop water systems.
The Group also develops solutions to help customers address their own water issues
Measuring water withdrawals and detecting leaks
To optimise its water consumption, the VINCI Group focuses on enhancing how it measures water withdrawals at its sites and detecting leaks within its own activities. VINCI’s business lines use several smart tools to gather data on water and employ sensors to detect leaks.
Percentage of VINCI Airports sites equipped with remote reading water meters
In 2025, VINCI Concessions accelerated the deployment of Smart Metering, begun in 2024. The tool communicates with water meters to monitor water withdrawals in real time and automatically detect leaks. In 2025, over €2.5 million was invested to support water conservation initiatives at airports, including the installation of meters. New meters were installed at Funchal and Ponta Delgada airports in Portugal and Tampico airport in Mexico. Meters installed at London Gatwick airport in 2024 detected a leak, which contributed to reducing purchased water consumption by more than 38,000 litres in 2025. The business line plans to equip all its airports with remote reading water meters by 2030. Thanks to this rollout, leaks have been detected and repaired, generating significant savings and contributing to the goal to reduce water withdrawals by 2030. At Funchal airport, the new meters enabled the detection and repair of a leak of close to 75,000 cu. metres. At Manaus airport, automated equipment – self-closing time delay faucets, faucet aerators, urinal sensors and water meters – was installed, enabling the daily tracking of water withdrawals and the fast detection of leaks or excessive consumption.
VINCI Autoroutes has begun optimising its processes to reduce water usage for its own operations, including for the sanitary and other facilities made available to customers at directly managed service and rest areas. The business line has pledged to reduce its water withdrawals by 10% from 2018 levels by 2030, across the entire geographical scope of its operations. This target was exceeded in 2025, with an 18% reduction in water withdrawals from 2018 levels. By 2030, 100% of its motorway infrastructure will be equipped with remote reading water meters.
VINCI Construction also uses measurement tools to help conserve water resources. The Building France Division is working to equip all worksites with smart water meters.
Reducing the water needs of infrastructure and worksites
50% reduction in water withdrawals per unit of traffic at VINCI Concessions, excluding VINCI Autoroutes (in litres)
By implementing more precise monitoring of water withdrawals, Group entities are empowered to find solutions to reduce their infrastructure’s water usage. In addition, as part of VINCI’s commitments to the act4nature international initiative, which it renewed in 2024 (detailed in paragraph 2.6, “Preserving natural environments – Biodiversity (ESRS E4)”, page 238), the Group carried out a mapping of its fixed sites in areas of high or very high water stress in 2025. An analysis of the results is in progress.
VINCI Concessions (excluding VINCI Autoroutes) has set a target to halve water withdrawals per unit of traffic by 2030. In this context, VINCI Airports is continuing to implement its POS water reduction plan (focusing on conservation, optimisation and awareness) on all its infrastructure. In addition to airports with the highest water consumption, airports located in areas of high water stress will be prioritised. Several Portuguese airports have implemented a predictive watering system that adjusts the amount of watering based on soil humidity, weather conditions and the type of plants being watered. The system has led to a 20% to 30% reduction in withdrawn water. VINCI Concessions is also drafting drought management plans in anticipation of the water restrictions that may be imposed in the event of a drought. These plans, developed as a priority for areas with a high risk of water stress, define degraded modes of operation for specific infrastructure assets to reduce their water needs. Faro airport has a management plan in place in the event that watering and car washing are prohibited.
Promoting water recycling and reuse
To optimise the use of water resources, the Group is implementing recycling or reuse solutions at various VINCI Construction and VINCI Concessions sites. These contribute to reducing water withdrawals in the Group’s own operations and in services provided to customers.
At VINCI Concessions, rainwater is increasingly being collected and reused in its networks. In 2025, 18 sites were equipped with water collection systems. For example, in the Dominican Republic, the upgrade of a terminal at Las Américas airport included the creation of a new roof of roughly 3,600 sq. metres to harvest rainwater. At Belgrade airport in Serbia, the terminal rebuilding and expansion project included a rainwater harvesting system on the new rooftops, complete with filtration and disinfection treatment. Since its installation, over 1,000 cu. metres of water have been collected.
