voestalpine isovac® - Nachhaltigkeit - greentec steel

Sustainable voestalpine premium quality with reduced carbon footprint

Ten percent of the direct carbon emissions at the Linz site are avoided through processoptimized operation in the production of greentec steel. Using a balance model, these saved emissions are allocated to the flat steel products supplied by the voestalpine Steel Division. 

The material and processing properties of the steel are not affected in any way by the carbonreduced production route. Each high-quality voestalpine steel strip product is available with its unique profile of benefits and a reduced carbon footprint. 


Convincing advantages:

  • Reduced specific carbon footprint
  • Reduced Scope 3 emissions at the customer

  • Individually adjusted carbon footprint based on a verified balance model

  • Unchanged range of grades and dimensions in proven voestalpine premium quality.

  • No change in material and processing properties because the chemical analysis and mechanical profiles remain unchanged.
