Introduction: Collect It Once, Use It Twice
A steel producer needs much the same primary data for a CBAM emissions figure and for an EN 15804 EPD. Collect it once, in the right structure, and you serve both — and you are ready when an EU customer or a specifier asks.
The single most common regret we hear from producers is not having the data when they needed it. This is the checklist to fix that — the inputs that feed both your CBAM position and your EPD, gathered once.
The Checklist
| Data point | CBAM | EPD |
|---|---|---|
| Metered electricity consumption (and source / PPA) | Yes (monitoring; indirect reported) | Yes (A1–A3 GWP) |
| Fuel and reductant use by type | Yes (direct emissions) | Yes |
| Material inputs: ore, scrap, alloys, precursors | Yes (precursors) | Yes |
| Direct process emissions | Yes (the chargeable figure for steel) | Yes |
| Production volumes per product / CN code | Yes (per tonne, per CN) | Yes (declared unit) |
| Production route per line (BF/BOF, DRI, EAF) | Yes (route benchmark) | Yes |
| Supplier emissions data for precursors | Yes | Yes (upstream) |
| Carbon price paid in country of origin | Yes (deduction) | — |
| Monitoring plan & system boundaries | Yes | Yes (PCR boundary) |
Why Structure Matters
The figures differ between CBAM and EPD (different gases, allocation and verification — see EPD and CBAM), but the primary data is the same. Capture it per installation, per line and per reference year, and you can produce a CBAM dataset, an EPD, and an answer for any customer without starting over each time. To model what your CBAM exposure looks like once you have the numbers, use the cost guide and calculator.
How EPD Polska / Multicert Can Help
We help producers set up this data foundation once and turn it into verified EPDs and a CBAM-ready dataset. Contact us for a data-readiness review.
FAQ
Will the same number work for both CBAM and the EPD?
No — the outputs differ. But the inputs overlap heavily, so one well-structured dataset feeds both.
What is the longest lead-time item?
Installation-level monitoring of energy and process emissions. Start there; it is entirely in your control.
