Carbon Accounting Software for Australian ESG and Sustainability Consultants

ESG and sustainability advisory firms sit at the intersection of AASB S2 disclosure preparation, materiality assessment, transition planning, and stakeholder engagement. The strategy and narrative work stays with the advisor. What compounds unmanageably per additional client is the underlying data collection, extraction, factor application, and audit trail. Carbonly is the ledger and evidence layer that lets the advisor scale without turning the practice into a data-clerk operation.

What changes for esg and sustainability advisory consultants

  • ESG advisory teams from Big 4 climate risk practices to boutique climate advisory firms use Carbonly as the underlying ledger under their engagement
  • Multi-tenant per-client workspace with strict isolation - every client tenant has its own factor library, audit trail, and users
  • Consultant workspace switch via MCP - Claude Desktop or ChatGPT connector lets the advisor query any client tenant in natural language
  • The strategy, materiality assessment, scenario analysis, and transition planning remain the advisor's authored work; the metrics section is auto-generated from the ledger
  • Per-project pricing (Small, Medium, Large, Enterprise) with $100/month workspace minimum so a starter client fits alongside an ASX 200 reporter
  • Auditor Workspace lets the client's external assurance provider walk the evidence pack directly, without asking the advisor to prepare it manually

What the system does

  • AI document engine reads supplier invoices, utility bills, fuel dockets across 8 file formats - same engine on every client tenant
  • Per-supplier extraction templates auto-derived per-tenant (strictly org-scoped) for the specific suppliers each client uses
  • AASB S2 disclosure PDF and Word output auto-generated from the client's ledger with paragraph-level references
  • MCP server with 8 smart tools (ask_copilot, take_action, upload_document, check_compliance, generate_report, email_report, switch_context, connect)
  • JV consolidation with operational, financial, and equity-share methods for client engagements with joint venture structures
  • Restatement register captures written justification when the advisor amends prior-year figures

Frequently asked

Do we position against ESG advisory firms or with them?

With them. Every blog on this site is written on the assumption that ESG consultants are buyers of the platform. Carbonly is the extraction engine, factor library, and audit trail underneath the advisory workflow. Strategy, materiality assessment, transition planning, and stakeholder engagement remain the advisor's authored work.

How does this differ from a carbon-only consulting engagement?

The platform capabilities are identical - the workspace structure is per-client. ESG advisory engagements typically extend to scenario analysis (AASB S2 paragraph 22) and transition planning; those authored artefacts sit alongside the ledger in the same client workspace and export together for the assurance provider.

What about scenario analysis under AASB S2 paragraph 22?

Carbonly stores the emission ledger, factor library, and climate risk register that feed the scenario analysis. Carbonly does not run climate scenario models internally - those remain the advisor's authored work (typically referencing IPCC AR6, IEA WEO, or NGFS scenarios). The Auditor Workspace bundles the scenario documentation with the underlying ledger for reasonable assurance walk-through.
