Technical Paper: Reducing CO2 Emissions in Tunnel Construction From a Material Technology Perspective.

Tunnel and underground construction is a material-intensive undertaking that involves the use of large quantities of concrete. Considering the carbon footprint, the material properties of the building material and the optimization of the quantity used play a decisive role. In terms of achieving carbon neutrality, a fundamental transformation in the construction industry is thus unavoidable.

In this article, our highly respected tunneling specialist, Wolfgang Aldrian, imparts invaluable expertise on:       

  • How to declare and reduce CO2 emissions per cubic meter of concrete
  • To design concrete formulations with climate-friendly materials


  • Why sustainable tunneling is an interdisciplinary task and requires a multidisciplinary team
  • What measures need to be addressed in the future
