Carbon Accounting Software for Finance Teams

Ledger-style data model. Reconciliation checksums. Versioned methodology. Separation of duties. OffGridFlow is what a CFO actually wants when sustainability lands on the 10-K.

Start Free TrialReview the workflow

When climate disclosures entered the 10-K (SEC Climate), the annual report (CSRD), and the CARB filing (SB 253), emissions data became financial data. CFOs and controllers inherit a new line item that their existing sustainability tools were never designed to defend.

What finance teams need that most tools miss

  • Immutable ledger so prior-period disclosures can be reproduced on demand
  • Factor snapshot locks so restatements are explicit and traceable
  • Approval workflow with separation of duties (preparer, reviewer, approver)
  • Change log with field-level before/after and actor attribution
  • Reconciliation checksums that prove the PDF matches the underlying data
  • Multi-framework output from one source of truth

Carbon close alongside financial close

Run the carbon close on the same monthly rhythm as the financial close. Import activities, run calculations, review anomalies, submit for review, approve, lock factor snapshot. Next year's assurance engagement reconstructs last year's numbers without needing last year's spreadsheets.

What it replaces

Six-figure Big 4 engagements, bespoke consulting spreadsheets, ad hoc email chains with suppliers for Scope 3 data. OffGridFlow starts at $6,500/year and produces the same audit-ready draft outputs — with a published methodology auditors can reference.

Frequently Asked Questions

Why should the CFO own carbon reporting, not just sustainability?

Climate disclosures are now financial disclosures. SEC Climate, CSRD, and SB 253 require Scope 1/2 (and material Scope 3) to appear alongside audited financials. A sustainability tool that lacks ledger discipline creates restatement risk. Finance teams that own the data pipeline avoid that risk.

How does OffGridFlow compare to a general ledger?

Activities are analogous to transactions, factors to chart-of-accounts mappings, the calculation ledger to journal entries, approval workflow to close-period controls, and factor snapshots to accounting-policy version locks. If you can defend a financial close, you can defend an OffGridFlow close.

Can we use the same workflow for multiple frameworks?

Yes. Reconcile once, disclose many times. The same activity ledger produces SEC, CSRD, SB 253, CBAM, and IFRS S2 draft outputs with each framework's required packaging. You maintain one source of truth.

Does OffGridFlow integrate with our ERP?

SAP S/4HANA connector, plus CSV and API fallbacks. Activity data ingestion can be scheduled so the carbon close becomes a monthly rhythm alongside the financial close.

What about internal controls?

RBAC with admin/user/viewer roles, approval workflow with separation-of-duty enforcement, immutable audit logs, and change-log field-level tracking. All documented in the public Trust Center.
