The EU carbon border mechanism, known as CBAM, counts the emissions embedded in imported steel, and that includes emissions from the materials and intermediate products used to make it. For Indian steel plants, this means tracing carbon through sinter, pellets, coke, hot metal, direct reduced iron and crude steel, then carrying it into every downstream product. Plants that can do this with reliable data protect their margins and their EU customers. To see how this could work in your plant, you can review a precursor tracing approach with our team.

Where CBAM standsThe Definitive Period Has Started and Data Quality Now Matters
CBAM moved from a reporting phase into its definitive period on 1 January 2026. EU importers now need to account for embedded emissions in what they bring in.

The steel chainEmissions Pile Up as Material Moves Through the Plant
Each stage adds emissions, and each stage feeds the next. Tracing means following the material and its carbon together.
Raw materials
Iron ore, pellets, coal and fluxes enter the plant
Intermediate products
Sinter, coke, hot metal or direct reduced iron are made
Steelmaking
Crude steel is produced from the intermediates
Rolling and finishing
Downstream products inherit the carbon of earlier stages
CBAM treats certain intermediate products as precursors, and their embedded emissions flow into the goods made from them. Confirm which materials count under the current regulation.
What to trackPrecursor, Emission Source and Data Needed
| Stage or precursor | Main emission source | Data you need |
|---|
| Sinter and pellets | Fuel and process emissions in agglomeration | Fuel use, production tonnes, carbon content |
| Coke | Coal carbonisation and fuel | Coal input, coke output, by-product streams |
| Hot metal or pig iron | Reduction in the blast furnace | Ore, coke and fuel inputs, tonnes produced |
| Direct reduced iron | Reductant and process fuel | Reductant use, product tonnes, fuel |
| Crude steel | Furnace fuel, electrode and flux use | Charge mix, additives, tonnes cast |
| Rolled products | Reheating furnace and process heat | Fuel per tonne, yield, product tonnes |

Calculation stepsFour Steps From Plant Data to a Product Figure
1
Define the boundary
Set which processes and materials belong to each product.
2
Measure and calculate
Collect fuel, material and emission data and apply factors.
3
Allocate
Share emissions between products using agreed rules.
4
Carry forward
Add precursor emissions into downstream products.
Write the method down. Verifiers and EU customers will ask how each number was produced.
Where the data livesBring Plant Systems Into One Emissions Layer
Most of the needed data already exists, but in separate systems.

Keep raw data, calculations and approvals together. An evidence trail saves weeks during verification.
Layers of boundariesFour Levels That Keep the Calculation Organised
Installation
The plant or site as a whole, with all its processes.
Production process
Each process such as sintering, ironmaking or steelmaking.
Precursor
Intermediate products moving between processes.
Final product
The goods shipped to the EU customer.
Working from the top down helps make sure no emission is missed and none is counted twice.
Measure or calculateTwo Ways to Obtain the Numbers
Calculation-based
Uses activity data and emission factors
Common for fuels and materials
Needs good records of quantities
Cheaper to run day to day
Measurement-based
Uses direct gas measurement
Needs certified analysers and procedures
Can improve accuracy for some sources
Costs more to install and maintain
Most plants combine both, using whichever is practical and acceptable for each source.
Indian plant realitiesFive Issues Plants Often Face
1
Multiple production routes
Blast furnace, coal-based DRI and scrap-based steelmaking can sit on one site.
2
Captive power and shared utilities
Allocating shared fuel and steam needs clear rules.
3
Variable raw materials
Ore, coal and scrap quality changes affect emissions.
4
Manual records
Paper logs slow down evidence collection.
5
Product mix complexity
Many grades and sizes need consistent allocation.
Starting with the biggest route and product groups gives results sooner. To plan your first scope, ask our team about phased precursor tracking.

Where emissions come fromAn Illustrative Split by Production Stage
The split differs widely between routes. This example shows why tracing stages matters. It is illustrative only.
15 percent: Sinter and pellets
Agglomeration fuel and process emissions.
50 percent: Coke and ironmaking
The largest source in an integrated route.
20 percent: Steelmaking
Furnace fuel, electrodes and fluxes.
15 percent: Rolling and finishing
Reheating furnace fuel and process heat.
Direct reduced iron and scrap-based routes have very different shapes. Each route needs its own map.

Frequently asked questionsWhat Indian Steel Plants Ask About CBAM Precursors
What is a precursor in CBAM?
A precursor is an input material that is itself made in a carbon-intensive process and whose embedded emissions pass into the final product. In steel, intermediates such as pig iron and direct reduced iron are examples. Confirm the current list with official guidance.
Review your precursors.
Do we have to use actual emissions or can we use defaults?
EU importers can use default values, but these are typically conservative and may raise costs. Using actual plant data requires verification by an accredited verifier. Many exporters aim for verified actual data.
Ask about actual versus default data.
Do indirect emissions from electricity count for steel?
Under the current definitive rules, only direct emissions are counted for iron and steel. Rules can change, so check current guidance and keep electricity data anyway for other reporting needs.
Discuss reporting scope.
How do we handle plants with several routes?
Treat each production route as its own flow, with clear boundaries and allocation rules between products and shared utilities. Documentation matters most for shared fuels and mixed charges.
Ask about multi-route plants.
How long does it take to set up tracking?
A first working version for one route and a few products can take weeks to a few months, depending on data quality. Plan extra time for meter fixes and for verifier feedback.
