Next, to assess the resilience of all its activities and assets across the value chain, the Group developed ResiLens, an internal tool created by the Resallience engineering and design office (Sixense, VINCI Construction), specialised in helping regions adapt to climate change. The ResiLens solution is coordinated centrally but in use in all business lines. It helps to identify assets exposed to climate risks – not only fixed worksites, but also temporary projects – and can be used to launch more in-depth vulnerability assessments as needed. ResiLens uses global mapping technology to evaluate an asset’s exposure to 14 climate risks, such as floods, drought, storms or cyclones, rising sea levels and heat waves, taking into account the critical levels for each type of infrastructure. Using IPCC data corresponding to the most pessimistic scenario (SSP5-8.5), exposure is calculated for different time horizons: 2030, 2050 and 2070. A preliminary vulnerability analysis is systematically performed using ResiLens for any major project submitted to the Risk Committee.
These ResiLens assessments – covering all of the Group’s activities and assets, across the entire value chain, using data from the IPCC’s SSP5-8.5 scenario – show that, although extreme weather events such as flooding or hurricanes may occur in the short term, the most significant material impact is to be expected in the long term, due to a probable increase in the frequency and intensity of these events. They also indicate that concessions activities, which are long-term, are more vulnerable than construction activities, which involve shorter time frames and worksites that are very local in scope.
The Group therefore focuses on concession assets in its vulnerability assessments. In 2025, VINCI Concessions plotted a map of the most vulnerable airports and international motorways. VINCI Autoroutes conducted a criticality analysis of its national network in 2020. This study assesses changes in weather parameters in the long term (2035) and very long term (2085) and their impact on motorway infrastructure. It is based on two climate scenarios, RCP 8.5 (business as usual) and RCP 4.5 (ambitious policy to reduce greenhouse gas emissions).
VINCI’s worksites and activities are more specifically exposed to the following climate risks:
In the short term, the Group has identified opportunities related to work undertaken to adapt to climate change. VINCI provides regions with concrete solutions in the construction and financing of infrastructure adaptation projects (sea walls, drainage systems for heavy rainfall, reservoirs for river discharge, reconfiguring of stream and river channels, urban cool islands, water desalination plants, etc.) and the eco-design of adapted buildings. Projects aimed at preventing flooding, including the Springbank Off-stream Reservoir project in Canada, which began in 2022 (see paragraph 2.2.2.2, “Climate change adaptation”, page 220), totalled more than €130 million in revenue for VINCI Construction companies in 2025.

Acting for the climate requires a transformation of the Group’s activities by optimising its energy consumption and promoting widespread use of renewables to reduce its dependence on fossil fuels. This also means rethinking the way its projects are conceived and designed so as to develop more resilient, low-carbon and energy-efficient buildings and infrastructure. In addition, new solutions need to be created that will transform mobility, housing and lifestyles to help its customers and end users reduce their carbon footprint.
A detailed description of VINCI’s environmental ambition is accessible to all its stakeholders on the Group’s website. It addresses the impacts, risks and opportunities (IROs) presented in paragraph 1.1.2.6, “Results of the double materiality assessment”, page 189. VINCI’s deployment of its climate strategy, whether with regard to mitigation or adaptation, is not limited by resource availability.
Since 2007, VINCI has maintained a proactive approach to reducing and monitoring its greenhouse gas (GHG) emissions covered by the Kyoto Protocol (see paragraph 5.4.3, “Greenhouse gas emissions reduction plan and performance”, of the methodology note, page 290), in line with the “Accelerate the environmental transition” commitment from its Manifesto. At the Shareholders’ General Meeting of 8 April 2021, the shareholders approved the Group’s environmental strategy and transition plan. These are fully aligned with the Group’s growth strategy, which involves investing in the energy sector, especially renewables (see “The Group’s business model for all-round performance” in the institutional section of this Universal Registration Document, page 6, and section 1, “General information” of this sustainability report, page 187). The transition plan is consistent with the Paris Agreement goal to limit global warming to well below 2°C by the end of the century. The Group aims to reduce all of its greenhouse gas emissions, mainly through two commitments:
