VINCI Construction is also working with its suppliers and customers to use recycled steel on a large scale in its buildings and structures, such as the future Maison LVMH – Arts, Talents, Patrimoine, a conversion project carried out by the Building France Division. The share of recycled steel used has risen at VINCI Construction, accounting for 47% of the steel consumed in 2025 (30% in 2024), of which 88% for the Building France Division and 82% for the Major Projects Division.
The Road France Division of VINCI Construction is acting in several areas to limit the impacts linked to the transport of these materials: optimising the distances travelled, ensuring the widespread adoption of covered trucks, investing in internal B100 refueling systems, significantly increasing two-way freight flows between production sites, and transforming materials and works procedures. Discussions are being held with transport providers to promote the use of more efficient transport modes with lower emissions.
VINCI Construction is also working to diversify its bitumen formulations. In 2025, it trialled an innovative biogenic bitumen, produced with a paper industry co-product, at an EST Microsurfacing worksite in the United Kingdom. An environmental product declaration (EPD) will be made for the binder to quantify its environmental impact.
VINCI Construction’s Building France and Civil Engineering France divisions also develop designs for hybrid wood and concrete structures, providing the means to lessen reliance on concrete in favour of materials with a lower carbon impact. These actions are described in paragraph 2.3.2.1, “Promoting the use of construction techniques and materials that economise on natural resources”, page 228.
Responsible procurement
The Group is working to reduce emissions associated with its purchases by setting up selection criteria and responsible procurement processes. These actions are presented in detail in paragraph 3.2.2.1, “Human rights and health and safety issues for procurement and subcontracting”, page 269. Some VINCI Construction divisions are collaborating with their main suppliers on reporting the carbon impact of their concrete and steel purchases.
VINCI Energies has reinforced its responsible procurement practices by implementing a responsible procurement charter, incorporating environmental criteria into supplier assessments and frequently working with its suppliers to reduce their environmental impact. For example, opportunities were provided to learn about low-carbon cables. Since May 2024 in France, national selection and bidding processes have included an ESG scoring system for suppliers.
F. Decarbonising motorways
Number of electric vehicle charge points per 100 km in France
VINCI Autoroutes has taken initiatives to decarbonize road infrastructure since 2021, some of which were published in the report “Décarboner l’autoroute : une urgence écologique” (Decarbonising motorways: an ecological emergency), co-authored with the consultancy Altermind. In 2023, VINCI Autoroutes joined the Alliance pour la Décarbonation de la Route (Alliance for Road Decarbonisation), through which it collaborates with a range of public and private sector partners to design effective solutions to reduce the carbon emissions generated by road transport. With this aim, VINCI Autoroutes is committed to developing carpooling and public transport on motorways. A program is under way to develop carpool parking facilities at motorway entrances and exits, and to be linked up as soon as possible to public transport services: 68 facilities were in service at end-December 2025 (59 in 2024). The number of multimodal transport hubs and park-and-ride lots in service is also growing.
The deployment of electric vehicle charging infrastructure is gathering pace to support the acceleration of electric mobility. In 2025, VINCI Autoroutes had more than 2,400 EV charge points in its network (2,100 in 2024). Development of EV charging infrastructure especially increased at rest areas, with 399 charge points in 2025 (215 in 2024). Mobile EV charging stations and roadside assistance from “blue vest” staff have been tested to supplement charging station capacity and limit wait times during high traffic peaks. The VINCI Autoroutes network provided 55 EV charge points per 100 km in 2025.
VINCI Autoroutes actively promotes electric road transport and contributes to research. In partnership with TotalEnergies, Enedis and six European manufacturers, VINCI Autoroutes has published a study on charging needs for electric long-distance heavy vehicles. In late 2025, nine charge points for heavy vehicles were installed across road networks. VINCI Autoroutes is also leading the “Charge As You Drive” consortium made up of VINCI Construction, Gustave Eiffel University, Hutchinson, two technology suppliers and Cerema. Since end-2024, the consortium has been testing two wireless charging solutions for electric heavy vehicles in real conditions on the A10 motorway. The first solution uses electromagnetic induction technology and the second conductive charging with a central rail. The tests carried out in September 2025 demonstrated that enough power can be transferred (200 kW) to charge trucks.
G. Decarbonising building and infrastructure use
Eco-design
Eco-design involves the re-engineering of construction processes to limit the quantities of materials required or to use materials with lower emissions or recycled components. The Group offers a wide range of sustainable products and materials to its customers. Before these solutions can be made available, impact studies must be carried out to obtain tangible evidence of their environmental benefits.
Several eco-design initiatives are under way in the Group. At VINCI Construction’s Major Projects Division, the Environment in Design (EiD) approach takes account of environmental issues right from the initial design phase (see paragraph 2.3.2.1, “Promoting the use of construction techniques and materials that economise on natural resources”, page 228). Thanks to this approach and the tool provided by the Infrastructure Sustainability Council of Australia, the City Rail Link infrastructure project in Auckland, New Zealand, successfully doubled passenger capacity while reducing emissions from materials by 15%. The project obtained the highest sustainability rating awarded to an infrastructure project in New Zealand. VINCI Construction is also continuing its life cycle assessments of several of its products, including high-percentage recycled roads and Power Road® technology, which was deployed for 26 projects in France and abroad at end-2025.
