Our steel classification The CO2 label shows you at a glance in which emission class the steel is produced. Under the current climate protection agreements, steel producers are to convert steel production and make it "cleaner" in several development steps and process variants by 2050 at the latest. The classification shows 7 levels from G (high CO2 pollution) to A (very low CO2 pollution). The first materials in level C can already be offered today. Please contact us. It is possible to select the material in such a way that CO2 savings of up to 75% are possible.
