Data in. The right number out. Nothing files without a record.

Production volumes, fuel and energy consumption, and purchased electricity — from whichever system you already use to track them.

• CSV or Excel upload, for plants that track this in spreadsheets today.
• Direct Tally or SAP connectors, for plants where it already lives in an ERP.
• AI extraction from invoices and utility bills, for the data that only exists on paper.

The point is not to make you change how you keep records before you can start — it's to get what you already have into one place.

One data set, run through the methodology for your sector and regulation — the engine knows a tonne of clinker is calculated differently from a tonne of primary aluminium, and that CBAM's embedded-emissions method isn't CCTS's GEI method, even when they're both drawing on the same plant.

That means the same underlying numbers produce both a CBAM-compliant embedded-emissions figure and a CCTS GEI figure — you enter your plant data once, not twice.

Where supplier-verified data exists, it's used in place of EU default values automatically.

For CBAM, a report your importer can file through the EU's registry. For CCTS, BEE's Form A — the performance assessment itself, generated from the same calculation, with the evidence pack behind it.

A CCTS filing needs Form B as well: your accredited verifier's certificate. We render it from the verification the agency actually recorded, and won't produce it before that exists — because under §5(1) a Form A without a Form B isn't a filing.

If you're obligated under both regimes, both come off the same underlying calculation, so the numbers can't quietly drift apart between them.

Every event — a data upload, a supplier declaration, a recalculation, a filing — is written into a hash chain: each entry's hash is derived from the entry before it, so nothing can be quietly edited or deleted after the fact.

Your auditor doesn't get a PDF export of your evidence — they get read-only access to the actual chain, and can independently confirm it hasn't been tampered with.
