Our steel mill buys coke from Shanxi. Is the coke maker's emission a CBAM precursor?
No. Coke is not a CBAM precursor. Its carbon enters your own mass balance as an input when it is burnt or used to reduce ore, and the coking plant's emissions stay upstream. Count them in Scope 3 category 1 for your corporate footprint.
In the CBAM figure
The carbon content of purchased coke is part of the installation's mass balance, so the CO2 it releases in the furnace is counted as direct emissions. What happened at the coke oven is not added.
In your corporate footprint
- Scope 1: CO2 from the coke you use.
- Scope 3 category 1: the coke maker's own emissions per tonne.
- Scope 3 category 4: rail or truck transport.
What to ask the supplier
- Carbon content and moisture per lot.
- Emissions per tonne of coke, with the method used.
What Senseible does here
Senseible reads fuel, electricity and production documents into dated, fingerprinted installation records, the starting point for the actual emissions an EU importer asks for.
