With a worldwide fleet of over 80,000 passenger and utility vehicles, fuel consumption relating to the use of vehicles by VINCI employees is a significant source of GHG emissions for the Group. Reducing these emissions requires studying relevant, locally available travel solutions, as well as transitioning the vehicle fleet and travel policy. The actions taken range from optimising journeys and kilometers travelled to the use of low-emission vehicles, awareness initiatives and training in eco-driving practices.
More and more light and utility vehicle fleets are being replaced with electric or other alternative energy vehicles. In 2025, 56% of new vehicle orders were for electric or other alternative energy vehicles (44% in 2024). At 31 December 2025, VINCI’s fleet in France comprised more than 30% all-electric and plug-in hybrid vehicles (21% in 2024). The Group aims to have converted more than 50% of its fleet in France to low-emissions vehicles by 2030.
VINCI Construction trained over 60% of its employees in eco-driving in 2025 (as in 2024). At VINCI Energies, eco-driving training continued in 2025 and more than 6,000 EV charge points were deployed internally across its fixed sites to facilitate electric mobility.
All Group companies encourage carpooling from worksites and operating sites. At several Cobra Energía (Cobra IS) worksites, employees are provided with means of collective transport, by bus or van, to travel around the site.
B. Site machinery and heavy vehicle performance
The consumption of energy relating to the use of site machinery and heavy vehicles is a major source (over 30%) of VINCI’s Scope 1 and 2 emissions. To reduce the corresponding emissions, VINCI entities are working with their suppliers to take action in three key areas: monitoring consumption in real time, electrifying their fleets of site machinery and trucks and using biofuels instead of diesel.
To monitor its consumption, VINCI Construction continues to roll out e-Track, which captures data for machines, trucks and utility vehicles fitted with telematics systems, with a view to optimising their use and therefore their energy consumption. This tool was operational for more than 66% of the VINCI Construction fleet in 2025. VINCI Construction GeoInfrastructure has developed Linaster, which provides the same functionality designed specifically for earthworks machinery. Sogea-Satom (Europe Africa Division) has rolled out a system to monitor consumption for each of its vehicles. An alert is triggered if consumption is excessive. VINCI Construction is teaching operators about reducing idle times worldwide, including through Energic challenges and 15-minute environment sessions.
VINCI is also modernising its fleet of machines and trucks. Although the large-scale electrification of construction vehicles remains hampered by technical constraints and long wait times for deliveries, significant progress was observed in 2025. Several experiments were carried out in the VINCI Construction and VINCI Energies divisions. They related to projects to electrify worksite machines and other heavy machinery, fully electrify worksites, connect equipment to the grid and use solar energy to power equipment and generators. Trials were also conducted—by VINCI Construction’s Specialty Networks Division, for example—to connect concrete plants to the grid and equip them with additional battery packs. These projects act as springboards toward widespread electrification solutions.
Biofuels are being used more widely and accounted for 4% of the Group’s total energy consumption in 2025, up from 3% in 2024 (see paragraph 2.2.3, “Performance monitoring”, page 222). Biofuels serve as a transition solution pending the electrification of site machinery. Their use, especially that of HVO100, is increasing in VINCI Construction, VINCI Autoroutes and VINCI Energies divisions, where it replaces diesel, which continues to be heavily relied on to power site machinery. For the Gate Tank 4 project being built by VINCI Construction, which will expand a liquefied natural gas (LNG) terminal in the Netherlands, hydrotreated vegetable oil (HVO) is being used to fuel the equipment. In 2025, 83% of VINCI Autoroutes’ patrol and response vehicles ran on XTL fuel, pending an electrification solution.
C. Optimising energy for industrial activities and buildings
Reduction of energy consumption by asphalt plants, in kWh/tonne of asphalt produced
Although energy consumption at asphalt plants has edged down since 2018, their energy performance—measured by the average amount of energy required to produce one tonne of asphalt — has deteriorated slightly. In 2025, this performance stood at 81 kWh per tonne produced.
This slight decrease is the result of several factors. First, only about five sites are being renewed each year, despite a dedicated investment policy and the improved energy performance of the most recent plants. Second, bitumen must be rejuvenated before it can be incorporated into production and therefore increase the proportion of recycled materials (reclaimed asphalt pavement). This rejuvenation process is more energy-intensive than manufacturing asphalt from virgin aggregates and bitumen. Lastly, the operating model influences a plant’s energy consumption, whether it operates continuously or in batches. Site location is a significant factor in determining the production method.
As a result, industrial activities vary in energy efficiency across the Group’s different geographies. Upgrades have continued at asphalt plants in France. Some facilities have been designed to meet ambitious performance standards. Energy consumption at industrial sites therefore remained stable in 2025.
VINCI Construction’s industrial facilities also continued to lower their energy consumption, in particular in North America. Six VINCI Construction USA plants obtained Energy Star certification in 2025 and are now among the country’s top 25% energy performers (as mentioned in paragraph 2.1.2.3 “Eco-labelling and certification”, page 208).
