cobank.ai is a carbon accounting platform that turns every invoice line into a verifiable, hash-sealed CO₂e ledger entry, replacing weeks of spreadsheet work with an afternoon of automated calculation. It classifies each line against versioned factor libraries like BAFU and DEFRA, and generates audit-ready reports that follow the GHG Protocol and ISSA 5000 standards. The system’s SHA-256 snapshot hashes allow external auditors to verify closed periods byte-for-byte without manual re-entry.

Problem
Companies preparing carbon emissions reports under frameworks like VSME, CSRD, or bank climate-risk requests rely on manual spreadsheet work to classify thousands of invoice line items, match them to emission factors, and document the process for auditors. This takes two weeks per period, produces inconsistent results, and leaves an evidence trail that is difficult for assurance teams to verify efficiently.
Solution
cobank.ai provides a carbon ledger that automatically ingests invoices from Bexio, e-invoice XML formats, CSV/Excel, and PDFs via OCR, then classifies each line against a versioned factor library from sources like BAFU, DEFRA, GLEC, and IPCC AR6. Every line receives a factor match, confidence score, and reasoning trace, with low-confidence items routed to a reviewer queue. At period close, the platform generates a single SHA-256 snapshot hash that seals the period and makes the entire ledger verifiable by auditors. The system supports Scope 1, 2, and material Scope 3 categories under the GHG Protocol Corporate Standard and produces VSME-aligned or GHG Protocol-compliant report exports, reducing period close from two weeks to an afternoon.
Target Audience
Primary customers are Swiss SMEs and mid-sized companies filing VSME-aligned emissions data or bank climate-risk reports, plus larger enterprises in mandatory CSRD scope and the audit firms that review their emissions data.
Features
- Automated ingestion from Bexio ERP, XRechnung, ZUGFeRD/Factur-X, PEPBI BIS, CSV/Excel, and PDF via OCR, with API ingest on higher tiers
- Per-line classification against a versioned factor library (BAFU 2025, DEFRA 2024, GLEC 2025, IMO 2025, IPCC AR6) with effective dates and source citations
- SHA-256 hash-chained ledger where every edit is linked, and each closed period is sealed under a verifiable snapshot hash
- Three calculation methods used in priority order: physical activity (quantity × factor), distance × weight freight (ISO 14083:2023), and spend-based multipliers with confidence flags
- Free auditor read-access with hash-chained evidence packs and ISA 320/ISA 530 sampling surfaces, reducing audit time from ~40 hours to ~6–10 hours
- GHG Protocol reporting with operational control boundary, location-based and market-based Scope 2, and computed Scope 3 Category 3 figures from fuel quantities
