A catalyst maker asks our Rustenburg platinum smelter for carbon data. Is it a CBAM good?
No. Platinum group metals are not CBAM goods. The buyer wants a Scope 3 figure: emissions from mining, concentrating, smelting and refining per ounce or kilogram, where Eskom electricity is usually the largest part. Give the allocation basis between metals.
What drives the figure
- Electricity for furnaces and concentrators, at the Eskom grid factor.
- Diesel for mining equipment.
- Coal or reductants in smelting.
Allocation
One ore yields platinum, palladium, rhodium and base metals. Say whether emissions are split by mass or by value; value allocation puts most of it on the precious metals.
Format
Car catalyst makers usually want kilograms of CO2e per kilogram of metal, with the year and the grid factor used.
What Senseible does here
Senseible reads bills, fuel invoices and production records into dated, fingerprinted records, so the figure you send a buyer can be traced to its documents.
