Which steel carbon figure should a Jamshedpur ancillary unit use for steel bought from the integrated mill?

Use the mill's own product figure for the grade and year you bought, from its product footprint, EPD or CBAM data, and keep the document. Only fall back to a published average if the mill will not share one, and label it. Steel is usually most of an ancillary part's footprint.

What to ask the mill or stockist

• kg CO2e per tonne for the product: coil, plate, bar or section.
• Year, boundary and route.
• Whether any low carbon claim rests on certificates and how they are tracked.

Through a stockist

If you buy from a service centre, ask for mill test certificates and the mill's figure. Add cutting and transport separately.

Then add your own

Your electricity, fuel and process scrap, split by parts made. Process scrap sent back to the mill is reported as waste, not subtracted.

What Senseible does here

Senseible reads steel, electricity and fuel invoices into a dated, fingerprinted record, so the steel tonnes and supplier figure behind a part trace back to the documents.

• Green steel certificates
• Mill certificate CO2 for a forged part
• Jamshedpur steel for EU buyers
