GreenSteel 100 option
20 bathtubs of 50 kg each, made from 100% CO₂-reduced steel
CO₂-reduced steel
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.
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:
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.
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 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):
20 bathtubs of 50 kg each, made from 100% CO₂-reduced steel
40 bathtubs of 50 kg each, made from 50% CO₂-reduced steel
80 bathtubs of 50 kg each, made from 25% CO₂-reduced steel
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:
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.
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.
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:
