Across the world, nearly 200 m3 of concrete is poured every second. Concrete is one of the most widely used industrial products - even more so than oil. Although we know all about its advantages in terms of land development, its drawbacks are significant. It is one of the major sources of CO2 emissions due to its cement content. 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?

Will electrical cars be mandatory by the year 2030?
Are European car manufacturers poised to switch to all-electric? On 10 September, MEPs in Brussels gave their support for draft legislation setting a 45% reduction in CO2 emissions from cars and vans under 3.5 tonnes by the year 2030, with an intermediate target of 20% by 2025. A much more ambitious roadmap than that of the European Commission, which tabled plans for a 30% reduction by 2030.

Stéphanie Barrault, head of the Circular Design Experience project: applying all of the circular-economy principles to the construction sector
In France, the construction sector generates more than 40 million tonnes of waste every year and consumes large quantities of resources to meet the needs of renovation and new construction. A situation that contributes to threatening certain resources with scarcity, or even shortage, in the medium to long term. For example, this is the case with sand, of which the sector is a large consumer.
One of the most significant potential areas for saving energy and greenhouse gases is the thermal renovation of buildings. But we are not renovating enough. The method needs to change, and this will probably happen via industrialisation. Industrialisation, boosted by the European EnergieSprong project, means improved performance and quality of use.
The need to make cities denser and to develop original tools for collaboration is giving rise to new ways of approaching the design of urban planning and housing. There are two objectives: to get citizens involved in urban projects that affect them directly; and, in parallel, to promote the design of open and custom collective housing in their own image.
The Floatgen project, the largest offshore wind turbine in France on which construction is soon due to be completed in the port of Saint-Nazaire, has won the Usine Nouvelle 2017 Renewable Energies Trophy for Energy Transition at the ceremony organised on Tuesday 16 May in the presence of Jean Jouzel, climatologist and former vice-president of GIEC.
Regulatory pressure is growing on how building and public works waste is processed. The sector produces 70% of waste in France (245 million tonnes, 46 million tonnes of which from the construction sector).
Improving thermal insulation, reducing the carbon footprint, optimising energy performance… The solution to all these linked objectives lies in the design phase with the choice of materials. A dilemma or a boon?
The Olympic and Paralympic Games represent a wonderful opportunity to rethink the regions through ambitious urban projects. This event associated with the Greater Paris area will enable the capital to perfect its status as a global city and accelerate the transformation of the Ile-de-France department. Spotlight on the impact of the Olympic Games on our cities and on the economic benefits derived from the magic of Olympism.
