Module 4 of 9 · A3 · Calculating embedded emissions of aluminium goods

3.Complex goods: aluminium products

Episode A3-02 · Simple vs complex goods · 3:05

SEE = (AttrEm + Σ Mi × SEEi) ÷ AL

or per tonne: SEE = ae + Σ mi × SEEi, where ae = AttrEm ÷ AL and mi = Mi ÷ AL.

  • ae = the forming process's own emissions per tonne of product.
  • mi = specific mass consumption: tonnes of precursor per tonne of product. You must share it with your buyer.

KEY Mi is all precursor used, including metal lost as scrap, offcuts or residues. That is why mi is usually above 1.
