Guidelines
VINCI strongly emphasises listening and dialogue with its stakeholders in all its business lines.
Respecting ethical principles
VINCI has adopted a stronger framework so that all its employees can contribute effectively to the Group’s integrity and transparency requirements.
Whistleblowing procedure
VINCI has set up a system to gather and process reports, whereby any physical person may securely and confidentially submit suspicions relating to the Group’s activities.
Duty of vigilance plan
VINCI presents its duty of vigilance plan every year, in accordance with regulations on the duty of vigilance of parent companies and subcontracting companies.
Ethics and compliance
VINCI has evolved around strong values that mould its culture and guide its actions. Ethics is at the heart of all VINCI’s business relations with its stakeholders. The Group expects the highest standards of conduct from each of its employees based on a sense of honesty, loyalty, respect for dignity and individual rights. This commitment is reflected at the highest level in the Group.
The Code of Ethics and Conduct lays down all the principles of business ethics that apply in all circumstances, in all countries where the Group operates and to all companies and their employees. It is used in tandem the Anti-corruption Code of Conduct, which details the rules concerning the prevention of all acts of corruption, notably identifying risks in business processes and defining conduct to be avoided.
These two documents are available in 30 languages on the Group intranet and website. They can therefore be accessed by almost 100% of employees in the official language of their country and are included in the new employee welcome kit. 91,000 employees had undertaken, as at end-2025, to comply with and enforce the Code of Ethics and Conduct and the Anti-corruption Code of Conduct within their scope of responsibility.
Training and information
To enable all employees to contribute effectively to preventing and detecting acts of corruption, at the level of their responsibilities, specific training programmes have been developed and deployed at all levels in the organisation. These modules complement the general e-learning training courses on the Group platform, such as the "Anti-corruption – challenges and risks", "Conflicts of Interest" and "Competition law" courses.
Partners and subcontractors
The integrity and transparency requirement does not just apply to Group companies and employees, but also to its partners and subcontractors. In addition to their technical expertise and ability to fulfil their duties, subcontractors are also assessed for their own commitment to respecting human rights and business ethics.
VINCI Integrity
The online whistleblowing platform called VINCI Integrity is available in five languages on the Group intranet and website. In addition to the systems specific to each entity, it enables employees and all other stakeholders to report any inappropriate behaviour in the areas of human rights, business ethics, environmental risks, and health and safety. It guarantees full traceability and anonymity of all discussions, and the protection of whistleblowers.

Governance
The Ethics and Conduct Department reports to the Executive Management. Working closely with the business line departments, corporate functions and the Group’s Ethics and Vigilance Committee, and relying on both internal expertise (Legal, Audit and Human Resources departments, Ethics and Compliance Club, GDPR steering committee and Human Rights steering committee) and external expertise, it coordinates the implementation of the prevention system.
Created in 2018, the Ethics and Vigilance Committee has seven members, five of whom are also members of the VINCI Executive Committee. It is responsible for implementing and updating compliance systems covered by Code of Ethics and Conduct, notably concerning the detection and prevention of acts of corruption and preventing serious breaches of human rights and basic freedoms, and the health and safety of people and the environment, attributable to the Group’s businesses.
It oversees changes to the Code of Ethics and Conduct and the Anti-corruption Code of Conduct.
Building leverage through active collaborations
The issues facing VINCI and its entities are often complex and involve multiple players throughout the value chain. Although VINCI continually enhances its risk prevention and management systems, it does not always have the necessary leverage to pursue every possible action, due to its position in the value chain and the cyclical nature of its activities.
For this reason, as a complement to its in-house efforts, VINCI has joined a number of external coalitions and initiatives, working in collaboration with a variety of stakeholders on tools, methodologies and actions that promote human rights, to better address human rights issues.
Building Responsibly
of which VINCI is a founding member. Because the building industry faces specific challenges, this coalition of engineering and construction firms works to develop common approaches and tools, share practices, engage with all stakeholders in the value chain (customers, investors, subcontractors, etc.) and find concrete and collective solutions to the sector’s challenges.
Entreprises pour les Droits de l’Homme / Businesses for Human Rights
of which VINCI is an executive board member. This association of leading French companies is a forum for discussion, initiatives and proposals by these businesses to improve the integration of human rights into business policies and practices.
Leadership Group for Responsible Recruitment
which welcomed VINCI to its steering committee in June 2017. This collaborative initiative between leading companies and expert organisations strives to promote responsible recruitment practices and combat forced labour.
Global Compact
which VINCI signed in 2003. VINCI is a member of the Human Rights Club of the French network of the Global Compact.
World Business Council for Sustainable Development (WBCSD)
which VINCI joined after the organisation merged with Business for Inclusive Growth in January 2024. VINCI coordinates a WBCSD subgroup on forced labour and responsible recruitment.
Responsible purchasing: guiding the Group's purchasing partners towards overall performance
In line with the Group's commitments and values, VINCI expects each of its purchasing partners to respect and ensure respect within its own supply chain for the principles and values set out in our Global Performance Charter for Purchasing Partners.
From the moment we select our partners, we undertake to integrate social and environmental issues into every stage of our purchasing processes.
Our areas of action
We have a VINCI Responsible Purchasing Committee that includes the business lines and whose mission is to define and oversee the implementation of the approach within the Group.
We provide our employees with tools to help them deploy the approach: Group purchasing policy, Global Performance Charter for purchasing partners, e-learning, buyer training adapted to each business line, risk mapping by purchasing family and supplier audit grid.
- We include social and environmental criteria in the selection of our main purchasing partners.
- We evaluate and audit our main suppliers and subcontractors on relevant social and environmental issues, particularly in purchasing families with high sales potential and/or a high level of social and/or environmental risk.
- We support our purchasing partners in gradually improving the environmental, societal and social quality of their offers and practices.
- We develop partnerships and close relationships with suppliers and local small and medium-sized enterprises (SMEs).
