Your EU buyer needs your carbon per tonne.
Send it, or they pay on a standard figure for India. Unlike steel, your electricity counts here.
Is your product covered?
Tap it. The scheme is the Carbon Border Adjustment Mechanism (CBAM).
- Clinker: Covered (2523 10).
- Cement: Covered (2523). Keep the clinker share per type.
- Urea: Covered (3102).
- DAP, NPK: Covered (3105), except phosphorus and potassium only.
- Ammonia: Covered (2814).
- Nitric acid: Covered (2808).
- Potash: Not covered today (3104).
- Superphosphate: Not covered today (3103).
Check the code on your invoice and agree it with your buyer. The scheme is run by the European Union (EU).
Lay four sheets. That is your file.
Pick what you make, then tap each sheet.
Clinker and cement
1. Limestone carbon
Heating limestone in the kiln lets carbon dioxide out of the rock itself, like a cake letting out steam that was never fuel. For clinker it is usually the biggest part.
Your papers: Clinker made, or cement delivered with your clinker to cement ratio, from your plant registers and stock counts.
If it is missing: Your buyer uses the standard figure for the whole product.
2. Kiln fuel
Coal, petcoke, gas and alternative fuels burnt to heat the kiln. Start-up oil counts too.
Your papers: Fuel purchase bills and weighbridge slips with dates and quantities.
If it is missing: Your buyer cannot use your kiln, only the standard figure.
3. Power
Mills, kiln fans, crushers and packing run on power. For cement, unlike steel, electricity counts.
Your papers: Electricity bills in kWh, each month, times the grid factor.
If it is missing: This part falls back to the standard figure.
4. Clinker share
How much clinker sits in each tonne of cement. Slag and fly ash add little process carbon, so blends with more of them come out lower. Made-to-order blends need a clinker declaration for each consignment.
Your papers: Clinker share per cement type, from lab analysis or from deliveries, stock and additives.
If it is missing: Your buyer uses the standard figure.
Urea, DAP, NPK
1. Gas in the plant
Natural gas is both the raw material and the fuel for ammonia, the base of urea. It is the largest line for most plants.
Your papers: Gas purchase bills and meter readings with dates and quantities.
If it is missing: Your buyer uses the standard figure for this part.
2. Nitrous oxide
Making nitric acid leaks nitrous oxide, a gas that warms far more than carbon dioxide, like a small tap leak that floods the floor. Catalysts that cut it show up in your figure.
Your papers: Nitric acid plant records and catalyst records. If you buy your acid, ask your seller for their figure.
If it is missing: Without records, defaults apply and usually run higher.
3. Power
Compressors, granulation, pumps and bagging lines. For fertiliser, electricity counts.
Your papers: Electricity bills in kWh, each month, times the grid factor.
If it is missing: This part falls back to the standard figure.
4. Bought in, and nitrogen
Ammonia you buy carries its maker’s own figure. Your buyer also wants nitrogen content and form, such as urea or nitrate. Blended liquid batches report one weighted average.
Your papers: Supplier letters with the year, plus nitrogen content from your lab sheets.
If it is missing: Your buyer uses the standard figure for the bought-in part.
Ammonia, nitric acid
1. Gas feedstock and fuel
Gas reformed into hydrogen for ammonia, plus reformer and boiler fuel.
Your papers: Gas purchase bills and meter readings with dates and quantities.
If it is missing: Your buyer uses the standard figure for this part.
2. Bought-in hydrogen
Hydrogen made elsewhere and fed to your synthesis counts as an ingredient. Its maker’s figure adds to yours. Put that request into the supply contract, with a deadline before your buyer’s declaration.
Your papers: Tonnes delivered, the supplier’s figure, its method, and the period it covers.
If it is missing: Defaults apply for it and are usually higher.
3. Power
Compressors and utilities. For ammonia, electricity counts.
Your papers: Electricity bills in kWh, each month, times the grid factor.
If it is missing: This part falls back to the standard figure.
4. Nitrous oxide from nitric acid
The leak that comes with making nitric acid. Abatement in the acid plant lowers your figure.
Your papers: Acid plant production and abatement records.
If it is missing: Without records, defaults apply and usually run higher.
What silence costs you
The standard figure is the hotel rack rate: what you pay with no booking. It is set so it never understates.
- A blended cement with little clinker. Its real figure is usually well below the standard one.
- A fertiliser plant with good records. The standard figure is usually higher than a well-run plant's real one.
- Any plant that waits. Your buyer asks you to cut your price, or looks at a supplier who sent a number.
Worked example: the power sheet
Example: a cement grinding unit, per tonne of cement
35 kWh per tonne x 0.675 = 23.6 kg CO2 per tonne of cement from grinding power
Then add the clinker inside each tonne of cement, and kiln fuel if you run one.
The grid factor of 0.675 kg CO2 per kWh is the factor for FY 2025-26. The 35 kWh is an example. The clinker inside each tonne of cement adds the rest, so keep the clinker share per cement type on record.
A verifier signs it off.
Senseible builds the verifier-ready file and checks every figure in-house; an accredited verifier Senseible partners with signs it off, or the client sends it to their own.
Why this is not the same check
Actual figures need verification by an accredited verifier before an importer can use them for the definitive regime. The in-house check is not that verification. It is what makes the file ready for it.
Start with one gas or power bill.
Senseible connects your verified record to its financing partners for loans, credits and grants. Senseible does not lend. The partner decides, and nothing is guaranteed.
