Meanwhile, VINCI Energies is collaborating with design firms to create smart public lighting systems that reduce the dispersion of light and preserve dark corridors, which are essential for nocturnal biodiversity. In 2025, Omexom Act Smart Lighting (Australia) showed that this technology can reduce diffuse light by up to 50%. Citeos deploys high-performance equipment and automatic shutdown systems for its customers. The need to preserve dark corridors is systematically included in contracts for operating lighting systems.
Along with their institutional partnerships, VINCI companies engage in continuous dialogue with stakeholders. They strengthen communication with local residents near worksites and infrastructure in operation, through information meetings, improved signposting, worksite visits and new communication channels.
As part of its work to reduce noise pollution for local residents, VINCI Airports publishes information on flight paths and the results measured by its noise monitoring systems on the relevant airport’s website. Local residents can also report incidents directly on these visualisation platforms.
Worksite teams receive training on how to dialogue effectively with stakeholders, and digital tools such as MonChantier and InfoChantier facilitate communication with local residents. Reception offices are opened, information meetings are held and grievance committees are set up to ensure that local concerns are heard and resolved. At a large majority of the West delegation worksites of VINCI Construction’s Civil Engineering France Division, advanced measures have been taken to consult with local communities and residents. For large worksites, a grievance committee is formed to gather feedback from nearby residents. Meetings with the management committee are held on a regular basis to discuss and resolve complaints. For each reported grievance, actions are planned and carried out until it is resolved.
Grievances from local residents are monitored independently at the level of the Group worksites (see paragraph 2.4.2.1, “Policies and targets for preventing environmental pollution and incidents”, page 234). In 2025, no major environmental incidents were reported concerning negative impacts due to light or noise pollution or vibrations.
During the process of identifying material impacts, risks and opportunities (see section 1, “General information”, page 187), specific analyses were performed, focusing on water resources. Water consumption corresponding to water used to produce concrete and not returned to the natural environment was shown to be a material issue for the Group’s upstream value chain only. The Group’s sites and activities withdrawing significant volumes of water have been identified using the LEAP method (Locate, Evaluate, Assess, Prepare) developed by the Taskforce on Nature-related Financial Disclosures (TNFD). This involves the Group’s fixed sites, i.e. those operated by entities in the Concessions business and the quarries (dewatering water management). Analysis data from the Aqueduct tool developed by the World Resources Institute (WRI) was used and was also incorporated into ResiLens (see paragraph 2.2.1.3, “Climate change adaptation”, page 209), an internal tool for assessing vulnerability based on IPCC scenarios to 2030 and 2040, to specifically identify sites located in areas exposed to water risks (such as water stress).
Any financial impacts, controversies or disputes involving VINCI and water resources were also reviewed. The viewpoints of the main stakeholders concerned, identified below, were taken into account in assessing IROs.

As part of its environmental ambition, VINCI implements policies to conserve water resources throughout its value chain, especially in areas of water stress, and sets targets for business lines to optimise withdrawals, collect and reuse water (in particular by creating closed water loops), and implement water saving technologies. These targets are set as a voluntary initiative. Implementing Group policies to conserve water resources is an integral part of VINCI’s environmental ambition and falls under the responsibility of the Group’s Vice-President for the Environment.
