Total energy consumption by business line, with change

The energy consumption of construction activities accounted for 71% of the Group’s total energy consumption in 2025 (70% in 2024), mostly due to its industrial activities. The 2% increase in consumption in 2025 results mainly from the integration of new companies, including FM Conway (see previous page). VINCI Construction’s main reduction efforts involve both improving the energy performance of site machinery and heavy vehicles, by gradually replacing diesel with biofuels (see sub-paragraph B, “Site machinery and heavy vehicle performance”, of paragraph 2.2.2, “Climate strategy (policy, objectives and action plan)”, page 214) and optimising energy for industrial activities and buildings, which mainly involves substituting heavy fuel oil with lower-carbon energy sources (see sub-paragraph C, “Optimising energy for industrial activities and buildings”, of paragraph 2.2.2, “Climate strategy (policy, objectives and action plan)”, pages 214 to 215).

The Energy Solutions business accounted for 21% of the Group’s energy consumption in 2025. These activities posted a 2% rise in their energy consumption, driven by growth at Cobra IS.

The Concessions business represents 8% of the Group’s total energy consumption, which remained broadly stable in 2025.

Use of renewable energy

In addition to the initiatives taken by VINCI companies to reduce their energy consumption, the use of electricity from renewable sources and biofuels has risen sharply since 2018. In 2025, 768 GWh of renewable electricity was used (640 GWh in 2024), representing an increase of 20% compared with 2024. Renewable electricity accounted for 46% of total electricity used, compared with 40% in 2024, and came from several sources: purchases of renewable energy certificates (representing 64% or 488 GWh), renewable energy supply contracts (representing 16% or 125 GWh), off-site and on-site power purchase agreements (representing 13% or 102 GWh), and sites’ own energy production and self-consumption (representing 7% or 53 GWh). VINCI Concessions was responsible for 67% of the Group’s self-consumption of electricity produced on site. Biofuel consumption totalled 454 GWh, of which 61% was used by VINCI Construction.

Energy production

Energy produced by VINCI companies and not used by the Group was 9 TWh (7 TWh in 2024). This figure breaks down into 1 TWh of renewable energy (solar, wind, etc.), accounting for 11% of the Group’s total production (see activities described under “Supporting the transition to a low-carbon economy” in paragraph 2.2.2.1, “Climate change mitigation and energy”, page 218), and 8 TWh of non-renewable energy, accounting for about 89% of the Group’s total production.

2.2.3.2 GHG emissions

The methodology used to determine the greenhouse gas (GHG) emissions of VINCI’s businesses is based on the Group’s energy consumption data presented above as well as the emissions factors presented in paragraph 5.4.3.1, “Scope 1 and Scope 2 greenhouse gas emissions”, of the methodology note, page 290. Scope 1 includes direct emissions from the use of biofuels, fossil fuels (fixed sites, worksites and company vehicles), as well as non-energy emissions (VINCI Construction’s lime plants). Scope 2 includes indirect emissions produced to make energy (mainly electricity) purchased and used at fixed sites and for projects. Scope 2 emissions are calculated using two methods: location-based and market-based, which are described in paragraph 5.4.3.1, “Scope 1 and Scope 2 greenhouse gas emissions”, of the methodology note, page 290. The difference between the emissions values recognised using these two methods is due to the fact that market-based emissions take into account contracts for the purchase of electricity from renewable sources, such as off-site power purchase agreements, green electricity contracts and guarantee of origin certificates, signed for a total of 698 GWh in 2025. These contracts represented a reduction of 121 thousand tonnes of CO₂ equivalent, or 47% of location-based Scope 2 emissions in 2025.
