CO₂-reduced steel

Greensteel

With the GreenSteel option, you reduce the CO₂ footprint of your construction project and contribute to climate protection. You can choose from different proportions of CO₂-reduced steel.

This is how you reduce the CO₂ emissions of your product#

With the GreenSteel option, you can reduce the CO₂ footprint of your construction project and play your part in protecting our climate. You can choose between different proportions of CO₂-reduced steel:

  • GreenSteel 25: your product is made from 25% CO₂-reduced steel
  • GreenSteel 50: your product is made from 50% CO₂-reduced steel
  • GreenSteel 100: your product is made from 100% CO₂-reduced steel

A bathtub made from GreenSteel 100 is therefore 100% CO₂-free in steel production.

The GreenSteel option is available for most of our bathtubs, shower bases, shower areas, washbasins and urinals.

GreenSteel: What is it?#

From a purely accounting perspective, GreenSteel products contain the selected proportion of CO₂-reduced steel. Physically, however, this steel is no different from conventional steel. Our mass balance model ensures that the quantities are allocated correctly.

Our steel supplier guarantees the supply of a defined volume of green steel. Should demand for the GreenSteel option exceed available quantities, we will inform you before the contract is concluded. Our commitment: we use only steel for which CO₂ emissions have actually been reduced during production. We do not use steel whose emissions have merely been offset through compensation measures.

The mass balance model#

The purchased steel is reduced in CO₂ emissions by 10%. Therefore, 10,000 kg of steel corresponds, on a calculated basis, to 1,000 kg of steel that is 100% CO₂-reduced.

This allows the following products to be manufactured (example calculations):

Green steel: What ist it?

The steel for our GreenSteel products is produced using a process that emits less CO₂ than conventional steel production. Our steel supplier Voestalpine has implemented the following measures in steel production:

  • More scrap iron instead of raw ore
  • Less coke in the processes
  • More green electricity for melting steel

With all these measures, our supplier now produces 10% less CO₂ than with conventionally produced steel – these are real reductions in the production process, rather than offsetting. These methods for reducing CO₂ emissions lead to higher costs at the steelworks, which are reflected in the price of materials. The reduced CO₂ is allocated to the steel sold using an accounting model, which for us means the purchase price for CO₂-reduced titanium steel is slightly higher than for conventionally produced steel. GreenSteel offers exactly the same material quality.

Will I get a certificat for my GreenSteel product?

We certify on your order confirmation and on the invoice that you have purchased a GreenSteel product. On request, we can send you a copy of the certificates from our steel supplier Voestalpine. These certificates show how much CO₂-reduced steel Schmidlin has purchased and how large its CO₂ footprint is. The emissions reductions are calculated in accordance with the established ISO 14064-2 and EN 15804+A2 standards and verified by an independent testing institute.

Is a further reduction in CO₂ emissions planned?

By 2027, our steel manufacturer Voestalpine aims to reduce its CO₂ emissions by a total of 30% compared to the baseline year. Over the coming decades, it aims to gradually reduce CO₂ emissions to zero. To do this, it has introduced the following measures:

  • In the blast furnace, hydrogen produced from green electricity is increasingly being used instead of coke
  • More and more green electricity is being used to melt the steel.
