Greener construction, how to build greener?
Across the world, nearly 200 m3 of concrete is poured every second. It is one of the most widely used industrial products – even more so than oil, especially in construction. In spite of its advantages in terms of land development, it is one of the major sources of CO2 emissions due to its cement content. How to build greener?
About one billion tonnes of CO2 is released each year in the world by the cement industry. In the face of such global challenges and future changes in urbanisation, a revolution in construction methods is beginning. How can the construction sector commit to becoming more carbon-free? Can green building meet this challenge?

Every day, concrete endures attacks of all kinds (carbon dioxide from the air, chlorides, etc.). These aggressive substances corrode the concrete's metal reinforcements and cause deterioration. Unavoidable? Yes. Disastrous? No – not if you know exactly when to do renovation work.
A subsidiary of Bouygues Construction, Bouygues Bâtiment Ile-de-France is a player in the wooden construction sector. Today, it is investing in new construction methods to reduce the carbon footprint of the construction industry and develop new solutions for the cities of the future.
With environmental issues changing sites, Hésus offers construction industry professionals the chance to improve the management of excavated material using recovery solutions, combined with logistical expertise. This collaboration is already under way on Brézillon Environnement’s construction sites!

When health conditions required the widespread use of teleworking – wherever possible – in 2020, the sudden drop in travel, especially by car, was obvious to everyone. Some have been quick to conclude that teleworking has a beneficial impact on the environment. But what are the real effects of teleworking on mobility, and as consequence, on the carbon footprint of occupational activities?
Responsible for 67% of global GHG emissions, cities are on the front line of this challenge. Two high-emissions sectors - transport and construction - are of direct concern to them. What are their margins of manoeuvre and trajectories to become low carbon and carbon neutral? What are the major assets of the local scale?
“At the end of the crisis [health linked to the Covid-19 epidemic], the questions [regarding energy policy] will need to be readdressed.” So said Pascal Roger, president of the Federation of energy environment services (Fedene) to News Tank Cities on 01 April 2020. Currently, new renewable energies represent a prospect for ecological transition for this sector with photovoltaic in the lead, between giant power plants and innovative installations. Where are we ?
23,000 hectares: this is the average annual area of natural, agricultural or forest land reallocated to urbanisation in France over recent years, the equivalent of 2.2 times the area of Paris, 33,000 football pitches or 19 million parking spaces. A figure which makes France one of the worst European students with regard to restraining real-estate development. The impact on biodiversity and CO2 emissions are such that there is an urgent need to hold back this effect. Although the target of Zero net artificialisation (ZAN) was written into the national biodiversity plan in July 2018, the strategy, method and means of bringing this into reality remains to be specified. Likewise the search for a denser, viable and liveable urban development model in large conurbations as well as town centres and small and medium-sized towns.
