Carbon · ESG · EPR · Fleet emissions
Terrametri turns your operational data into a reconciled CSRD / ESRS E1 disclosure and a UK packaging EPR filing — with every figure traceable to the record, the exact factor version, and the person who signed it.
Built for the number that gets filed and assured — not a dashboard estimate. DEFRA/DESNZ factors across every scope for UK operations, EEA factors for EU electricity, period-correct by construction, XBRL output validated against the ESRS taxonomy.
Example figures — not your data
One platform, two filed outputs
The same engine takes utility bills, fuel cards, travel, waste, refrigerants and packaging specs and produces two regulated outputs an auditor can follow line by line.
A reconciled climate disclosure, E1-1 to E1-9, built from validated activity data — not a spreadsheet.
Producer obligation, tonnage and modulated fees — through to a Defra RPD export that ties to the kilogram.
Your fleet system stays the source of truth. Terrametri becomes the carbon-accounting layer on top — drivers key nothing new.
Why Terrametri
Plenty of tools will give you a number. For a figure that gets filed and may be assured, what matters is that the system won’t quietly produce one that’s wrong. Five guarantees, enforced in the engine:
The system refuses to price 2023 activity with a 2024 factor. It holds the record for review with a stated reason rather than quietly using the wrong year.
A disclosure figure resolves to its calculation, to the contributing records, to the exact factor version — with actor and timestamp at each step.
Whoever prepares the numbers cannot sign them off; whoever signs cannot edit them. Any later change to the data invalidates the signature.
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.
Without a valid legal entity identifier the filing stays a preview. Where the taxonomy has no proper home for a datapoint, it says so rather than inventing a mapping.
The system declines to produce a plausible wrong answer. For a number that gets filed and assured, that is the property that matters.
How it works
There is no side door. A number can’t enter the disclosure without carrying its evidence with it.
Activity arrives by hand, CSV, or API — energy, fuel, travel, freight, waste, refrigerants and packaging. It carries its period and its source.
Units convert to the canonical unit for the type. An unrecognised unit is refused rather than guessed at.
The factor is chosen from the library edition valid for the record’s own period and geography, then stamped on the record.
Validated records compute the ESRS E1 datapoints and the EPR tonnage and fees. Reconciliations run in code; anything with nothing behind it reads “not reported”.
A reviewer who didn’t prepare the figures signs them off. Signing freezes them; a held record or a stale figure blocks the signature.
A validated XBRL instance, an auditor evidence pack, and the Defra RPD CSV — each flags what it can’t resolve rather than inventing a value.
Who it’s for
A defensible Scope 1/2/3 number and packaging EPR, from one set of operational data.
Producer responsibility and carbon reporting for goods placed on the market.
Fleet, refrigerants and energy — the fugitive and mobile lines other tools handle poorly.
Sign client disclosures with an evidence trail, across multiple organisations.
Pricing
Platform pricing is fenced by legal entity, not by how much you record — never by vehicle, never by record. Four tiers, one included feature set, and a transparent rate for every additional entity.
For networks, associations and franchise groups managing many independent organisations
£3,500 for each additional entity, in any tier, pro-rated to your renewal date. Prices shown are ex VAT. Every tier includes unlimited users, free advisor and consultant seats, and a filing export that is never a paid add-on. A time-boxed early-partner rate is available — see full pricing.
Questions
Neither, and the difference matters. The figures are not estimates: each one traces to its records, the exact factor version and the person who signed it, with an auditor evidence package and a content-hashed assurance pack behind it. But the XBRL file is not submission-ready. We tag against the official EFRAG ESRS taxonomy and validate with Arelle, and 8 of the 41 datapoints we disclose have an official concept to map to — the rest, the headline gross total among them, need dimensional structures we don’t yet emit. Digital tagging is not law yet either: ESMA has still to issue the technical standards and the Commission the delegated act. So — audit-ready today, submission-ready when the rules land.
From loaded DEFRA/DESNZ editions for the UK and EEA EU-27 electricity factors for EU geographies, each with its own validity window. Factors resolve against a record’s own reporting period — the system will not apply a later year’s factor to earlier activity.
Your fleet system stays the operational source of truth. You export its vehicle activity and load it as a CSV or through the API — there is no live link to a fleet provider to configure — and the platform converts that activity into period-correct emissions, recording which of the three calculation tiers produced each figure. Drivers carry on using the system they already have. UK fleets are covered for fuel and distance; for EU geographies we hold electricity factors but no fuel source, so an EU diesel line is held for review with its quantity intact rather than estimated. Fleet is now being onboarded with early partners — see fleet emissions.
Whoever prepares a disclosure can’t sign it — a different reviewer attests it (four-eyes). Signing freezes the figures; any later change to the underlying data invalidates the signature, so the signed document and the live data can never silently disagree.
Yes. The same platform produces a UK pEPR filing with the Defra RPD export and the modulated fee behind it, from your product and placement data — with duplicate placements caught before they count toward the bill.
UK reporting (CSRD/ESRS E1 and UK pEPR) with DEFRA/DESNZ factors, and EU electricity via EEA factors. SECR draws on the same energy and emissions data, but has no output of its own yet. Multi-country coverage and further integrations are expanding; the early-partner cohort rate is held for three years as that happens.
Book a walkthrough and we’ll run a disclosure and an EPR filing end to end — ingestion to signed export — on data that looks like yours.
