At the end of 2023, VINCI developed a methodology to rank suppliers according to their risk exposure using a set of criteria that are weighted differently depending on their relevance for each purchasing category. These criteria include the supplier’s country of production, the country’s environmental risk level, its human rights risk level as assessed using VINCI’s Global Human Rights Risks Mapping, findings of ESG assessment questionnaires, any certifications obtained, amounts of spending on purchases, contract terms, the proportion of temporary staff and the use of subcontracting. The methodology was applied throughout 2025 for five priority purchasing categories by VINCI Energies in France and VINCI Construction’s Building France, Civil Engineering France, Road France and Networks France divisions. Specific action plans were developed and are being implemented by the relevant business lines and divisions.
Discussions with certain strategic suppliers (for example, for fuel, equipment leasing and concrete) are ongoing, with a view to reducing the Group’s Scope 3 greenhouse gas emissions.
VINCI has set up a dedicated online solution enabling whistleblowers to report serious damage to the environment. The system is managed by the Ethics and Vigilance Department. At the same time, the Environment Department monitors major environmental incidents as part of the Group’s annual reporting. A major incident is defined as one that requires the intervention of an external specialist and whose consequences stretch beyond the boundaries of the entity’s sites.
At the local level, the Group’s subsidiaries, divisions and business lines have their own procedures to notify management if an environmental incident occurs so as to promptly implement corrective actions. For example, the environmental managers of construction companies must make a detailed report of any environmental incident. The report is then shared with the top management of the relevant company.
VINCI companies dialogue with stakeholders and consult more widely with local residents, maintaining regular communications via a diverse range of channels. Details on how the Group consults with local residents are provided in paragraph 2.4.2.2, “Actions to prevent environmental pollution and incidents”, of the sustainability report, page 234.
A major incident is defined as a pollution incident for which the entity was liable during the year, having required the intervention of an external specialist (environmental remediation company, firefighters, etc.) where the consequences stretch beyond the boundaries of the entity’s sites or caused unforeseen harm to protected species and their habitats (deterioration or destruction) not covered by an authorisation from the environmental authorities. In 2025, 15 environmental incidents involving a VINCI subsidiary or one of its subcontractors were identified. These mainly included cases of pollution requiring the intervention of an external specialist where the consequences extended beyond the boundaries of the originating entity or worksite, as well as cases of destruction of a protected species’ habitat or degradation of wetlands outside the area covered by an authorisation. For example, while an asphalt plant was being cleaned, a bitumen remover solution of which large quantities were used overflowed from an oil separator, spilling into a ditch connecting to a waterway. The pollution was quickly brought under control and the site remediated. Improvements were also made to the site—a cleaning and refueling station—to prevent similar incidents from reoccurring.
VINCI’s Environment Department, together with the Audit and Internal Control, Ethics and Vigilance, Social Responsibility, and Procurement departments, supervises the work undertaken to monitor these environmental risk management measures and assess their effectiveness. This follow-up is performed on a continuous basis through the coordination of internal committees focusing on each of the Group’s material environmental issues (the Environment Committee, the Biodiversity Task Force, and the Circular Economy Task Force). Monitoring and assessment are also carried out by the Group’s network of environment officers. Among other tasks, these officers respond to the annual environmental reporting questionnaire, which contains about 60 quantitative indicators based on Global Reporting Initiative standards (a common set of indicators to assess companies’ sustainable development policies), the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD, see the cross-reference table, page 453), the Taskforce on Nature-related Financial Disclosures (TNFD, see the cross-reference table, page 454), and the Sustainability Accounting Standards Board framework (SASB, see the cross-reference table, page 455). The reporting process is an excellent resource for managing and following up on action taken to reduce the environmental risks relating to VINCI’s activities. It also incorporates data on the subcontractors of VINCI companies.
In addition, the Audit Department conducts an annual self-assessment of internal control relating to the following areas: the internal control environment, financial and accounting information, the environment, human rights, compliance and IT security (see paragraph 2.4, “Internal control”, of chapter D, “Risk factors and management procedures”, pages 182 to 184). The 2025 questionnaire included specific questions on the implementation of the CSRD.
