Use case
Carbon accounting
We're extending the same reconciliation and citation engine that grounds your financial model to emissions and consumption data, so a carbon figure carries the same evidence trail a revenue figure already does.

Designed to reconcile against
- Utility invoices
- Meter reads
- Supplier disclosures
- ERP exports
- Excel schedules
Why carbon numbers don't hold up
Most carbon accounting is estimated, siloed, and impossible to trace.
- Emissions figures get modeled top-down from industry averages instead of the bills and meter reads a business actually holds.
- Utility invoices, supplier disclosures, and spend data live in separate trackers that never reconcile with each other.
- A number in the sustainability deck rarely traces back to the document it was supposed to come from.
- Finance and sustainability teams keep two definitions of the same metric and argue about whose is right.
Rexfin's approach to carbon accounting
One trust chain, extended to emissions and consumption.
Concept preview · roadmap
An illustrative rendering of the direction, not a recording of a shipped screen: talk to us if evidence-grade carbon accounting fits your reporting cycle.
Reconciled, not estimated
The plan is to check emissions and consumption data against the source document the same way an actual is checked today, not model it top-down from an industry factor.
One chain, two domains
Carbon figures are designed to carry the identical trust chain financial actuals already do: filed, extracted, reconciled, cited, exported.
Same definitions, no new glossary
A metric would be defined once in the governed library finance already relies on, so sustainability and finance stop arguing over whose number is correct.
Key features, planned
What extending the evidence layer to carbon would look like
Scenario modeling for a reduction plan
Model a reduction target or an unmitigated baseline in plain language and see dependent lines recompute: the same deterministic recompute already used for financial scenarios.
58% Baseline
34% Reduction plan
86% Unmitigated
Coming soon
A citation for every emissions line
The intent is that any figure opens onto the utility bill or supplier record it was built from, plus the check that confirmed it agreed with the printed total.
Coming soon
One store for both kinds of actuals
Emissions and consumption data would sit in the same canonical atom store as financial actuals, addressable and versioned per close rather than living in a side tracker.

Not a rating. A chain.
The same chain finance already trusts, extended one domain.

Questions about carbon accounting on Rexfin.
Is carbon accounting available in Rexfin today?
Not yet. It sits on our roadmap as a direct extension of the reconciliation and citation engine already running for financial actuals; this page describes the direction, not a shipped module.
What data would an emissions figure be built from?
The plan is the same source documents a business already holds (utility invoices, meter reads, and supplier disclosures), checked against the printed total the same way a financial actual is today.
Would a carbon figure carry the same citation as a revenue figure?
That is the intent: every real figure in the product is designed to open onto the source page it came from, the extraction that produced it, and the check that confirmed agreement, carbon and finance under one discipline.
How would this differ from a typical top-down emissions estimate?
Reconciled to source documents rather than modeled from an industry-average factor: the same distinction Rexfin already draws for financial actuals versus a re-keyed spreadsheet export.
Does this require a separate ESG platform alongside Rexfin?
That's the problem this direction is meant to remove: one governed model and one trust chain instead of a financial system and a disconnected sustainability tracker.
