Carbon Accounting Software for CFOs and Finance Directors

AASB S2 pulled climate disclosure into the annual sustainability report and made the CFO responsible for signing off numbers that are as material to the market as the P&L. Corporations Act section 180 makes director sign-off personally defensible only if the reporter can prove reasonable grounds to believe the number is accurate. The 40-60 hours the sustainability team lost preparing walk-through evidence for year-one Group 1 assurance is what your finance team is about to inherit in year two under reasonable assurance. Carbonly closes that gap by making the audit trail a first-class object rather than an afterthought.

What changes for cfos and finance directors

  • Every emission record links back to the source document, the factor version applied, and the reviewer who confirmed it - section 180 defensibility is one click, not a week
  • AR5 for NGER (the CER submission) and AR6 for AASB S2 (the sustainability report) both render from the same activity data without double entry
  • Reporting period lifecycle mirrors the finance close - open, locked, submitted, archived - with restatement requiring written justification captured as load-bearing evidence
  • Custom dashboards reflect the live ledger so board reporting is not a PowerPoint rebuild every quarter
  • MCP server lets you ask ChatGPT or Claude Desktop "what does the audit committee need to see this quarter" and get an audited answer
  • Per-project pricing predictable and scoped by workspace size, not per-seat SaaS licence economics

What the system does

  • Auditor Workspace with dedicated read-only access for the external assurance team, one-click Evidence Pack export for ASSA 5010 walk-through testing
  • Factor version pinning per NGA edition (2024, 2025) - the answer to "which factor edition applied to FY25" is a single click on any record
  • Baseline snapshots for AASB S2 paragraph 21 comparative disclosures preserved immutably at period submit
  • JV consolidation across operational, financial, and equity-share methods so subsidiaries, associates, and joint ventures each disclose under the right boundary
  • Enterprise SSO, SCIM, MFA with security stepup, seven-year audit trail retention, Australian data residency
  • Executive Summary generator produces the AGM slide and board-pack chart set auto-built from the ledger

Frequently asked

How does this reduce personal director sign-off risk under section 180?

The four failure modes a director cannot defend on the stand are silent factor version drift, spend-based fallback when activity data was available, alias miscoding at volume, and missing provenance. Carbonly addresses each: factor version pinning per NGA edition, quantity-based extraction with methodology labels per record, Trust Graduation with reviewer-confirmed alias learning, and source-document provenance on every emission record. This is what "reasonable grounds to believe" looks like in a system.

What is the annual all-in cost for an ASX 200 deployment?

Per-project pricing by workspace size (Small, Medium, Large, Enterprise) with a $100/month workspace minimum. Watershed quotes A$37K-$264K per year and Salesforce Net Zero Cloud A$48K-$210K per year. Carbonly delivers the same enterprise-grade audit trail, AI extraction, and reasonable-assurance readiness at per-project pricing that scales with your actual workspace size, not per seat.

How does the Auditor Workspace change the reasonable assurance conversation?

The external assurance team logs in with dedicated read-only access, steps through any reporting period, and one-click generates an Evidence Pack - a ZIP that bundles every emission ledger row with its source document, extraction event, reviewer confirmation, factor version, and audit-event chain. This is built for ASSA 5010 walk-through testing. Year-two Group 1 companies moving from limited to reasonable assurance for Scope 1 and 2 find this is where the 40-60 hours of internal walk-through preparation goes.
