To date, around 10 divisions across the Group, in France and around the world, have already mapped their social and environmental risks, making it possible to consolidate a Group-level map and provide an overview of priority purchasing categories. The highest risk categories include temporary workers, transport services with drivers, subcontracting, steel, concrete, aggregates, sand and clay. Efforts have focused on these categories in particular, and targeted action plans have been drawn up for the main human rights and environmental risks in each category. Each of these priority categories is covered by specific risk management procedures in line with the salient issues identified. The scope and features of the action plans are defined and adapted in line with the level of risk identified during the mapping process.
VINCI is developing a series of tools to cover the various stages in the relationship with suppliers, from selection phase assessments through to the contractual framework. All of the tools, metrics, and action plans deployed aim to prevent and mitigate risks and adverse impacts on the planet, human rights and the health and safety of workers in the value chain.
Prioritisation of suppliers
The scope of the action plans implemented depends on the level of risk identified for each purchasing category, but may also factor in the level of exposure to suppliers’ social and environmental risks within a given category. VINCI has developed a methodology to rank suppliers according to their risk exposure using a set of criteria that may be weighted differently depending on their relevance for each purchasing category. These criteria include the supplier’s country of production associated with a risk level for the country, findings from ESG assessment questionnaires, any certifications obtained, amounts of spending on purchases, contract terms, the proportion of temporary staff and the use of subcontracting.
This methodology was applied for several priority purchasing categories, in collaboration with VINCI Energies in France, VINCI Construction in France, and VINCI Energies International & Systems. Specific action plans were developed and are being rolled out by the relevant business lines and divisions.
ESG assessment of suppliers
In 2025, VINCI overhauled its general ESG assessment questionnaire for suppliers, subcontractors and service providers. Used for several years by various business lines when selecting suppliers or at any time during the contractual relationship, it must also be applied for Group-level calls for tenders. Drawing on feedback from several years of use, a working group bringing together the business lines represented on the Responsible Procurement Committee and VINCI’s Social Responsibility, Environment, Ethics and Vigilance, and Procurement departments worked to enhance the questionnaire in various ways, such as automating and adapting the rating system based on the scale of purchasing partners, improving the relevance of questions and the options for answers, and automating progress plans.
For the purchasing categories with the highest risk exposure identified during the mapping process, a specific social and environmental risk assessment questionnaire tailored to the sectors or industries concerned is used in addition to the ESG questionnaire. This makes it possible to address the most relevant issues more effectively, depending on the sector covered by purchasing partners. To date, more than 20 specific social and environmental risk assessment questionnaires have been developed by the Group and its business lines in connection with calls for tenders.
Supplier audits and controls
For the priority purchasing categories, as part of a continuous improvement approach and to support suppliers with the highest exposure to social and environmental risk factors, on-site audits are planned and conducted directly by VINCI and the business lines. While prioritising Tier 1 suppliers, these audits can also be extended to Tier 2 and beyond, depending on the level at which the most significant social and environmental risks have been identified. During the last quarter of 2024, the Group launched an audit scorecard that can be adapted in line with the priority issues to be audited. Working with VINCI Construction’s Road France and Networks France divisions, this scorecard was tested on high-visibility workwear suppliers, ranging from Tier 1 to Tier 5. At the end of 2025, a working group was set up with responsible procurement correspondents from various Group divisions to supplement and finalise this supplier audit scorecard.
Human rights and health and safety audits are also carried out for VINCI subcontractors working on the Group’s projects, as presented in more detail in paragraphs 2.6, “Assessing the situation of subsidiaries, subcontractors and suppliers”, page 302, and 3.4, “Monitoring implementation and effectiveness”, page 314, both in chapter F, “Duty of vigilance plan.” Following each audit, a progress plan is drawn up and its implementation is monitored over time by the assessors.
Developing the level of knowledge and training all employees handling purchases to systematically take into account sustainability aspects is vital to the successful implementation of VINCI’s responsible procurement approach. The Group is therefore putting in place different approaches to further strengthen responsible procurement skill levels and provide each entity with ad hoc tools to implement this approach.
Raising employee awareness
An initial phase to raise awareness was carried out through a responsible procurement e-learning module to help employees absorb the content of the Group’s practical guide on responsible procurement. Available in five languages, this module is designed for all employees, across all business lines, and was completed by nearly 2,400 employees in 2025, taking the total figure since its launch at the end of 2020 to nearly 8,000.
Providing training for purchasers
A more in-depth course for the purchasing teams has also been in place since 2021, covering employees in key positions for the Group’s purchases. Due to the growing demand for sustainability skills development and to ensure that this advanced course remains relevant, its content was updated in 2024 and continues to be distributed across the Group’s business lines in France and around the world. At the end of 2025, this program was incorporated into VINCI Academy’s training catalogue, enabling wider deployment and improved monitoring and reporting.
To meet more specific needs and cover as many employees as possible, the Group is also working with the divisions to develop training programs with formats and contents that are better suited to the various roles, and particularly the legal, human resources, health and safety, and QHSE teams.
