The Group has thereby placed the fight against climate change at the heart of its priorities, and has implemented an innovative strategy to meet the real challenges of society, as well as meeting ambitious targets that it has set itself in low-carbon construction materials.
“Our challenge is to find the pathway for transitioning from being a traditional business to being a post-carbon business. It is important to keep on restoring and renovating, to choose materials according to their technical, environmental and economic performance. All this is to happen right from the design stage of the work being done.”

Following its ISO 50001 certification, Dragages Hong Kong has made economies within its perimeter of 87 000 MWh of energy, this being 71 000 tons de CO2e over a three-year period. This is the equivalent of 20 000 round-trip journeys between Paris and New York!
Wood acts as a trap for natural carbon, storing CO2 emitted by industrial activity. It is the low-carbon material par excellence. Modular buildings made of timber covering an area of 65 000 m² was built for the French army, heralding the beginning of wood construction in the world of large-scale projects.
Energy performance improvement is at the heart of the redevelopment project of the 17 buildings of the University of Bordeaux. The innovative glass facades make it possible for solar input in winter to be built up, and for the building to be kept cool in winter.
Carbon is responsible for 5 to 7% of world greenhouse gasses, of which 90% are directly linked to cement-making. Adding recycled materials reduces the carbon impact of concrete used in cement-making by 10 to 60%. Bouygues Construction is actually focussing increasingly on the use of CEM III, whose carbon impact is on average 2 times less than traditional Portland cement.
Wizom Connected delivers solutions for reducing a residential building’s carbon footprint during use. Consumption is better handled through the use of digital tools such as connected thermostats and best practice booklets sent to residents, contributing to behavioural change in order to better manage their energy consumption.
Key target: savings of up to 20% on heating for residential buildings!
Mix 3B is the fruit of the Group’s Research and Development, and it makes it possible to use a wooden façade while installing concrete during a building’s construction. It is a solution that makes best use of the two materials whilst considerably reducing the additional cost to the client compared to an all-concrete alternative.
