Breakdown of GHG emissions by sector
of activity in the world

The sectoral analysis reveals that the building sector, with its transport, is the largest emitter of GHGs, accounting for over 38%. Over its entire life cycle, 60% of the carbon footprint of a new building is linked to construction and 40% to operation.
Within the emissions linked to construction, the structural work alone accounts for 37% of global GHG emissions, with 59% being held by concrete.

The building industry, like other sectors, has mobilized its entire industry through the Global Alliance for Building and Construction (GABC) to try to reduce its cumulative carbon footprint over its entire life cycle: from the extraction of raw materials to the demolition of the building.
Of all the solutions developed to date, most of which are focused on the operational phase of the building, only those related to improving energy efficiency and the use of green energy sources are beginning to be implemented in the urban fabric of cities, but their environmental impact remains modest and far from the objectives set.

According to the French Institute for Energy Performance in Buildings (IFPEB):

« Regardless of the solutions implemented by manufacturers, getting on a carbon neutrality trajectory will involve a decrease in quantities »

« Even with a technological breakthrough, only a division by at least two of the volumes of concrete would make it possible to achieve the objectives of the SNBC »

NTIB is a solution that amply corroborates with the IFPEB recommendations, notably:

  • NTIB allows a massive reduction of CO2 emissions by reducing the volumes of concrete used,
  • NTIB, characterized by its simplicity of implementation, does not induce any additional cost to its use,
  • NTIB is identified as a reliable trend on the economic impact.
