Mitigate the impact on the climate

In response to the climate emergency, the Bouygues group is rolling out a Climate strategy to reduce greenhouse gas emissions over its entire value chain and to help its customers achieve their own decarbonisation targets.

Take firm action to reduce our carbon footprint and offer more virtuous products and services

Independent endorsement.

Bouygues has made a tangible pledge to reduce its carbon footprint and that of its customers by 2030. Its six business segments have had their decarbonisation targets endorsed by the Science Based Targets initiative (SBTi). This independent certification of Bouygues’ climate strategy shows that it is on the right track and encourages it to strengthen its practices in order to achieve its objectives. The drivers of its climate strategy:

  • Improve the reliability of carbon footprint calculations and life cycle analyses for its products. 
  • For scopes 1 and 2: change energy sources and reduce energy use (ISO 50 001, monitoring and management of energy use on worksites, energy efficiency, etc.). 
  • For scope 3, actions include eco-design, more ‘low carbon’ materials (low-carbon concrete, wood, etc.), greater circularity, redesigning current products and services to be more energy-efficient and better adapted to tomorrow’s climate, and supporting the Group’s suppliers and customers to collectively reduce their carbon footprint and use of resources. 

A managed climate strategy

The Group and each of its business segments manage the Climate strategy and its objectives within a specific governance structure, with regular monitoring by Bouygues’ Ethics, CSR and Patronage Committee and Board of Directors.
