What if an EU importer buys the same steel from two plants of one supplier?
Embedded emissions are worked out per installation, so the importer needs a separate figure for each plant that made the goods, even when the supplier, product and invoice look the same. Ask the supplier to name the installation on every shipment and to send per-installation data.
Why per plant
CBAM ties embedded emissions to the installation where the good was produced. Two plants with different routes or fuels can give very different figures for the same CN code.
What to ask for
- The installation that produced each consignment.
- Embedded emissions per tonne for that installation and period.
- Which plant supplied which share, when one shipment mixes production.
If the supplier cannot split it
Without per-installation data, the importer may have to use default values for the part it cannot attribute. Agree the split in the supply contract.
What Senseible does here
Senseible reads your fuel and electricity bills into dated, fingerprinted installation records, the starting point for the actual emissions your EU importer asks for, and its CBAM cost calculator estimates certificate cost from 2026 to 2034 for covered goods. Senseible does not verify emissions or file CBAM declarations.
