The record

Purpose: CarbonAccounting.ai turns existing spend data into a GHG Protocol ledger with an audit trail.
Classification: Its AI drafts Scope 1, 2 or 3 and Scope 3 category classifications for each AP line, with confidence stated per line.
Factors: The live classification engine supports EPA USEEIO, EXIOBASE-style EU and UK DEFRA factor families, and automatically computes metered lines activity-based.
Imports: The platform accepts CSV and XLSX imports for AP and ERP exports, utility bills and fuel cards, and remembers column mappings per source.
Evidence and review: Each posting links to its source line or document, and the review queue supports approving or overriding low-confidence lines with owners and timestamps.
Reporting: Compliance tier report packs provide structured outputs for CSRD ESRS E1, CBAM and ISSB IFRS S2, plus customer questionnaire answers.
Limits: The demo is a spend-based screening estimate, not an audit-grade inventory or substitute for a verified GHG inventory.
Privacy: Demo lines are sent to a server and model API for classification, then returned; the policy says they are not stored in a database, logged with the user's identity or used for training.
Security: The maker says the product offers EU data residency, encryption in transit and at rest, and a DPA, and states that it has no SOC 2 attestation or ISO 27001 certificate today.
Support: Support runs over email and is handled by the product builders, with replies usually arriving within a day or two.
Audience: The site describes Ledger for a first reporting year and one entity, Compliance for organizations in scope for CSRD, CBAM or SB 253, and Assurance for organizations facing third-party assurance.
