As a complement to adaptation research, Resallience and Sixense (VINCI Construction) use tools to assess corrosion in concrete structures, urban heat island effects, urban areas prone to flooding and the cost of climate change for infrastructure. VINCI Energies offers solutions enabling early fire detection in the vicinity of high- and medium-voltage lines, using video surveillance to monitor forests in real time in order to respond quickly with targeted action to protect infrastructure. One such solution, rolled out in Corsica, won a prize at the RTE Supplier Awards in 2022. It also makes use of critical path modelling to implement appropriate measures.
In 2025, Sixense Monitoring launched Initiative Sécheresse, a programme to equip more than 35 homes with sensors to monitor and repair the consequences of clay shrinkage and swelling due to climate change.
Training on how to use the ResiLens tool was delivered to more than 110 people in 2025 (90 in 2024). In 2026, VINCI Concessions will launch the Climate Adapt’action community for its operational teams, to share best practices, hear from experts and organise site visits on climate adaptation.
Awareness initiatives focusing especially on protecting the health and safety of Group employees while adapting to changing climate risks are described in paragraph 3.1.1.2, “Identification of impacts, risks and opportunities”, page 245.
In May 2025, Leonard compiled a catalogue of adaptation solutions as part of a larger climate adaptation foresight process. The purpose of the catalogue, which features a selection of climate adaptation solutions offered by VINCI, is to provide a convenient resource for employees looking for an effective response to the challenges of climate change to propose to customers. The solutions are sorted into three categories – analysis tools (described above), prevention solutions and repair solutions – and apply to four of the Group’s business areas: buildings and energy renovation, transport and roads, energy infrastructure, and water infrastructure.
VINCI anticipates the adaptation of cities and their energy, transport, water and sewer infrastructure by incorporating eco-design into all its projects. The Group makes constructions more resilient to weather events by introducing innovations and implementing technical improvements: reinforced sea walls, flood risk prevention areas, lift pumps, permeable asphalt to absorb water (Drainovia) during heavy rainfall, and heat-resistant materials to reduce the effects of temperatures over 50°C, such as light-coloured asphalt by Ecolvia Déco and Puma to reduce radiated heat. VINCI Construction is also developing technologies such as Biocalcis® and Greenfloor®. Biocalcis® is a soil treatment that uses biotechnology to strengthen soil, backfill materials and stone. It reinforces the stability of constructions and helps to prevent climate risks. Greenfloor® is a ventilated concrete slab system that uses clean ventilation air to enhance a building’s energy performance.
VINCI Construction has significantly scaled up its projects for climate adaptation, such as combating urban heat islands and soil unsealing, using their new Revilo® integrated offering (see paragraph 2.1.2.1, “Employee engagement”, page 206). In 2025, VINCI Construction continued work on several major climate adaptation projects: a sewer tunnel under the Thames, to intercept stormwater and wastewater during heavy rainfall, and the Springbank dry reservoir in Calgary, to protect the city from flooding by temporarily storing overflow from the Elbow River. In Morocco, the Sogea-Satom delegation is leading a seawater desalination project that will increase the production of drinking water by 90 million cu. metres per year.
VINCI Immobilier is incorporating summer comfort criteria into all its new residential property projects. In anticipation of high temperatures, it uses bioclimatic design principles and climate-adapted solutions to achieve a 20% to 50% reduction in the number of hours during which occupant comfort exceeds the threshold defined in the RE2020 regulation.
For short-term adaptation, VINCI companies regularly repair and restore infrastructure and power lines. In 2025, revenue from the Group’s adaptation projects was €141 million, compared with €118 million in 2024 (see paragraph 2.1.1.1, “Eligibility and alignment of VINCI’s revenue”, page 203). Following the flooding in Spain caused by the DANA storm (high-altitude isolated depression) at the end of October 2024 and Storm Martinho in Portugal in March 2025, Cobra IS teams worked to restore power and basic communications services to homes and infrastructure as quickly as possible.
Energy consumption is a central focus in the environmental action plans defined by VINCI companies, which aim both to reduce the amount of energy they use and use low-carbon energy whenever possible.
