Compliance with business ethics drives the Group’s performance

In 2006, the Bouygues group introduced a Code of Ethics (other languages available here), which reaffirms the Group’s key values of respect, integrity and responsibility.

The Code of Ethics is intended to guide managers and employees in their day-to-day decisions, regardless of their level of responsibility, or of the entity, project or country concerned.

The principles that govern the actions contained within the Code of Ethics are outlined in more detail in an Anti-Corruption Code of Conduct, several compliance programmes as well as specific policies:

These documents, which are regularly updated, describe the behaviour to be adopted and help employees make decisions in real-life situations.
The Ethics, CSR and Patronage Committee is systematically informed whenever serious breaches are observed and monitors the remedial measures. As with the parent company, each business segment has its own Ethics committee and Ethics officer.


The Group encourages freedom of speech and has rolled out a secure system for collecting and processing whistleblowing alerts. The system is accessible to all and guarantees the confidentiality:

  • of the whistleblower’s identity,
  • of the identity of the persons implicated in the whistleblowing alert, and
  • of any other information obtained ​.

Duty of Vigilance, a matter of great concern for the Group

The Vigilance plan includes measures to identify and prevent violations of

  • human rights and fundamental freedoms,
  • the health and safety of people, and
  • the environment,

resulting from the operations of Bouygues and its subsidiaries and those of their subcontractors or suppliers with which they have an established business relationship.


  • environmental damage, including water and soil pollution, biodiversity loss, and climate change mitigation and adaptation
  • human rights abuses and violations of fundamental freedoms, especially undeclared work, child labour and forced labour 
  • safety, workplace accidents, occupational illnesses and health
  • supply chains and outsourcing.


Updated in 2022, this charter sets out the key commitments that must be upheld by suppliers and subcontractors wanting to do business with the Group. Failure to uphold the rules outlined in this document, which is appended to orders and/or contracts managed by each purchasing department within the Group, can lead to measures up to and including termination of the contract.
