Partnership culture

A responsible supply chain

A responsible supply chain

Promoting sustainable and 
responsible practices 

Common principles and 
shared values

Our relations with suppliers and subcontractors are based on three principles: ethics, social responsibility and environmental issues.
In practical terms, this means that in every call for tenders, we incorporate specific environmental and social requirements: our suppliers are selected on the basis of strict CSR criteria, not just by taking account of cost or commercial performance.

We are also committed to working with our partners to help them reduce their carbon footprint and to support their initiatives to boost local employment. These commitments deliver tangible benefits for local communities and residents.

In practice, we use the EcoVadis platform to assess our suppliers’ CSR performance: 400 partners will be assessed by the end of 2026. These assessments allow us to measure progress, pinpoint areas of improvement and encourage the adoption of best practices. This helps strengthen our mutual trust and joint capacity for innovation.

An ambitious and responsible purchasing strategy

    Decarbonisation 

    We use a number of methods to measure and reduce emissions across our supply chain. Primarily, we focus on optimising the categories with the greatest impact (energy, fuel, concrete, reinforcement), developing circular economy practices and bio-based materials, optimising transport and using EPDs (environmental product declarations). These actions allow us to compare different solutions and highlight the emissions savings achieved on each project.

Le soleil orange éclatant illumine les toits clairs des bâtiments et les nuages, contrastant avec les teintes grises de la ville.

    Local economic development

    We prioritise SMEs along with social economy structures, such as the sheltered and protected employment sector. In 2024, we awarded several hundred contracts to local businesses, generating direct jobs and contributing to regional development.

    Commitment to human rights

    We prioritise risk prevention by conducting social audits and considering vigilance criteria from the moment partners are selected. This ensures compliance with international standards and enhances the integrity of our projects.

    Sustainable partnerships

    We support our suppliers in their CSR ambitions by providing progress plans, training and sector-focused workshops. This promotes collective skill development that benefits the entire industry, creating a virtuous circle of performance.

A central issue of environmental transition

We believe that we have a role to play in supporting our entire ecosystem in the transition to a more responsible model. To achieve this, we prioritise sustainable purchasing, which reduces our environmental footprint, and energy-efficient solutions; we choose local suppliers wherever possible to support regional economic growth; and we demand respect for human rights throughout our supply chain.

We work with a variety of partners – start-ups, SMEs, large corporations, local authorities, research laboratories and NGOs – to develop innovative solutions that address our challenges with respect to environmental transition, local economic development and human rights. Our collaborations with research laboratories, for example, enable us to test low-carbon materials, while our partnerships with local NGOs contribute to preserving biodiversity on our construction sites and to ensuring compliance with social standards.

The guarantee of a lasting relationship

Our certification for responsible procurement (the RFAR label) demonstrates our commitment in this area, including strict compliance with payment deadlines, balanced contractual relations, recourse to mediation in the event of disputes, and the inclusion of social and environmental criteria in decision-making processes.

Suppliers and subcontractors can be confident that this means a stable and fair contractual framework, which helps them to ensure the long-term success of their business. This recognition strengthens the structure of our procurement policy and guarantees our customers and partners relationships based on transparency and sustainability.

In addition, the ISO 9001 certifications held by several of Bouygues Construction’s entities reflect our dedication to continuous improvement and standardising of our practices on a global level.
