MAATIMAATI
Methodology

Every figure traces back to a method, a source, and a standard.

MAATI doesn’t compute a number and hope it holds up at audit time — the pipeline below is the same one every activity record passes through, from the moment it’s entered to the moment it’s locked into a disclosure-ready inventory.

  1. 1

    Activity data in

    Enter data by hand, or bulk-import CSV/Excel across every scope, with per-row validation so one bad line never blocks the rest of a batch.

  2. 2

    Emission factor resolution

    Factors resolve automatically against the reference dataset for the activity, region, and period, with full fallback tracking recorded whenever an exact match isn’t available.

  3. 3

    Validation

    Runtime checks flag anomalies, gaps, and inconsistencies before a record can move forward — completeness and plausibility are checked, not assumed.

  4. 4

    Approval workflow

    A Draft → Submitted → Approved → Locked lifecycle enforces segregation of duties at every transition. Once a record is Locked, it is immutable.

  5. 5

    Audit trail

    Every calculated figure carries its source document and the exact emission-factor version used to produce it — evidence, not just a total.
