  • Banked reductions can be sold by the customer under its own brand.
Does your company have its own carbon bank?

Customer which doesn't have a CO2 bank:

  • CO2 intensity values can be used to quantify the carbon emissions of the product the customer sells
  • The impacts associated with processing the steel (e.g. fabrication) should be accounted for along with any associated yield losses
  • It should be made clear that the final carbon intensity of the customer's product is calculated using a mass balance approach.
