Period-correct factors, enforced
The factor is chosen from the library edition valid for the record’s own period and geography, then stamped on the record. The system refuses to price 2023 activity with a 2024 factor.
Carbon accounting software
Terrametri turns your operational data into Scope 1, 2 and 3 emissions with period-correct factors — and keeps every figure traceable to the source record, the exact factor version, and the person who signed it. Built for the number that gets filed and assured, not a dashboard estimate.
What it does
The factor is chosen from the library edition valid for the record’s own period and geography, then stamped on the record. The system refuses to price 2023 activity with a 2024 factor.
A total resolves to its calculation, the contributing records, and the exact factor version — with actor and timestamp at each step. The auditor’s path is the product.
A record whose factor can’t be resolved goes to a review queue with a reason — it never quietly counts as nil, and a scope with no data reads “not reported”, never 0.
Who it’s for
A defensible Scope 1/2/3 number from the operational data you already keep.
Carbon reporting for goods placed on the market, alongside packaging EPR.
Fleet, refrigerants and energy — the mobile and fugitive lines handled properly.
Sign client figures with an evidence trail, across multiple organisations.
One platform
The validated activity behind your carbon number also drives a CSRD / ESRS E1 disclosure, a UK packaging EPR filing, and fleet emissions — one set of records, several regulated outputs.
Questions
A dashboard gives you an estimate; Terrametri produces the number you file and may have assured. Every figure traces to its activity records and the exact emission-factor version, a reviewer who did not prepare it signs it off, and any later edit invalidates that signature.
Scope 1, 2 and 3, computed from validated activity data — energy, fuel, travel, freight, waste, refrigerants and more — using the emission-factor edition valid for each record's own reporting period.
Loaded DEFRA/DESNZ editions for the UK and EEA EU-27 electricity factors for EU geographies, each with its own validity window. The system will not price earlier activity with a later year's factor.
Yes — the same validated data drives the ESRS E1 disclosure, with an XBRL instance validated against the ESRS taxonomy and an auditor evidence pack. See the CSRD / ESRS E1 page for detail.
