The U5 in Hamburg will be one of the most modern subway lines in Europe. It runs right through the city, will transport around 270,000 passengers a day and the frequency can be controlled “on demand” at peak times. Sustainability is already a top priority in the construction of the U5. You can find out more about Hochbahn U5 in the previous presentation.

Reinforcing steel, for which Sülzle Stahlpartner calculates a clear CO₂ footprint and which, in addition, also complies with defined CO2 limits, is making a decisive contribution to reducing CO₂ emissions in the construction of the U5.

The following factors make this success possible:

Knowledge of the supplier plants (keyword: EPD),

Steel obtained from electric arc furnaces with approx. 90 % recycled content,

Unambiguous material tracking through a digitized production process,

Adaptation of warehouse logistics for making low CO₂ material separately available,

TÜV validated calculation logic of the product carbon footprint.
