The future viability of the Group’s business activities hinges on its ability to address environmental challenges. 

Accordingly, Bouygues is committed to offering solutions that address the climate emergency, resource scarcity and rapidly retreating biodiversity. Bouygues supports its customers worldwide to reduce their carbon footprint.

The Group focuses particularly on…… 

…encouraging electric mobility

Transportation is a very important part of the Group’s climate strategy because it is the main source of CO2 emissions in the world. Bouygues is therefore innovating and working hard to provide public transport and soft mobility infrastructure (tram lines, cycle paths).

For example, Colas offers Wattway panels. When these are placed on cycle paths, they generate renewable energy as bikes pass over them, which can then be fed in to the power grid.    

The Group is also investing in electric mobility. The expansion of the charge point network is fundamental to encouraging the use of electric vehicles and therefore ultimately to stop using fossil fuels. The network of charge points installed by Bouygues Energies & Services avoids nearly 660 tonnes of CO2 each month. Their use is greatly facilitated by mobile apps and web sites which help geolocate them.

Bouygues also addresses these issues very early on by integrating charging solutions into the design of buildings. In 2019, the “Ready4Mobility” consortium brought together players from the construction and mobility sectors in order to draft a common set of guidelines to promote building/mobility convergence.

…safeguarding resources

The Bouygues group has committed each one of its business segments to redesign its processes, products and services to factor in circular economy principles in order to safeguard natural resources.

Construction businesses:

given that the construction industry generates 70% of all waste produced in France, the Bouygues group is rolling out solutions in four priority areas:  

1- the selection of sustainable and recyclable materials from the project’s design stage

2- a reduction in the volume of resources used during the construction stage

3- on-site recovery and repurposing  

4- recycling of materials 


Several million handsets are lying around unused in France. In reaction to this, Bouygues Telecom is running awareness campaigns to encourage people to hand them in for recycling as part of its 4R strategy (repair, recover, refurbish, recycle). As a result of this initiative, some 228,494 unwanted smartphones were recycled in 2020.


TF1’s set designers apply eco-design principles and recycle existing set components.  

…preserving biodiversity

The Bouygues group has been working for several years to limit the impact of its infrastructure projects on biodiversity in order to safeguard ecosystems and combat the loss of greenfield sites. It does this by:  

  • running R&D programmes to investigate infrastructure in urban environments (e.g. on green roofs) 
  • carrying out works to protect ecosystems, such as rewilding and restoring waterways  
  • creating labels such as BiodiverCity, which recognises new-build or renovation projects that factor in biodiversity. Nearly 9,000 housing units have either received this label or in the process of receiving it.
  • Bouygues Immobilier has set a target of making 25% of its projects (by surface area) biodiversity-positive by 2025. This term designates a site that contains more nature-supporting spaces post-development than it did in its initial state.
