Group 1 — Installation and processes
Where the boundary actually sits.
- Site plan and unit layout.
- Installation boundary exactly as it will be reported — including what is excluded and why.
- Process flow diagram for each CBAM good produced.
- Production routes mapped to CN codes.
Group 2 — Inputs and energy
What went in.
- Fuel consumption by type and quantity for the reporting period.
- Electricity consumption and its source.
- Raw materials and precursors, with their origin.
- Embedded-emissions data for purchased precursors — supplier records, not generic factors, where an actual value is claimed.
Group 3 — Production
What came out.
- Production quantities per good and per CN code.
- Co-products and the allocation rules applied between them.
- Reconciliation of production quantities to commercial and operational records.
Group 4 — Measurement and quality
How you know.
- Meter specifications, ranges and data owners.
- Calibration certificates for every meter that feeds a reported figure.
- Fault and outage log.
- Sampling and laboratory procedures, including frequency.
- Emission factors, with source, version and applicability.
- Documented procedure for treating missing data.
Group 5 — Management
Who approved it.
- The monitoring plan, in the version actually applied.
- Quality-control procedures over data collection.
- Change log with approvals.
- Named data owner for each source stream.
- Prior reports and any restatements.
One test that predicts the whole verification
Readiness testTake any single figure in your draft report and trace it, without help, to a primary record with a date, an owner and an instrument behind it. If that takes more than a few minutes for a material figure, the file is not ready — and no amount of report formatting will change that.
