Avarni Carbon Accounting & Supply Chain Emissions Platform

Avarni is a Sydney-based carbon accounting software company launched in early 2021 by Misha Cajic and Anuj Paudel, both formerly of Atlassian and Macquarie Telecom Group. It helps companies prepare audit-ready emissions data for Australia's mandatory climate reporting under ASRS / AASB S2, which is aligned with the ISSB standard, and to decarbonise their supply chains.

The platform imports activity data through OCR of invoices and connections to ERP systems such as SAP, NetSuite and Dynamics 365, then uses AI to classify general ledger lines and calculate Scope 1, 2 and 3 emissions with full calculation breakdowns and an emission factor library. Further modules cover targets, forecasting and scenario analysis, compliance reporting, audit and assurance support and supplier engagement, including tracking of supplier SBTi commitments. Customers include CSL, Maersk, Schneider Electric, Kagome and Cement Australia.

• Data import: OCR invoice import and ERP connections to SAP, NetSuite and Dynamics 365.
• AI emissions calculation: classifies ledger lines and calculates Scope 1, 2 and 3 with breakdowns.
• Emission factor library: access to factors used in each calculation.
• Targets and forecasting: scenario analysis and reduction pathway modelling.
• Reporting and assurance: ASRS / AASB S2 reports with a traceable audit trail.
• Supplier engagement: collects supplier data and tracks SBTi commitments across the supply chain.

A Vietnamese subsidiary of an Australian group can feed its ERP data into group-level ASRS reporting. A listed company preparing ISSB-aligned disclosures can calculate Scope 1 to 3 emissions from accounting data with an audit trail. A food or building materials producer can track which suppliers have set SBTi targets.

The company states it has served more than 450 organisations with a 100% audit pass rate and that a first filing can be ready in two to three months. AI reading of invoices and ledger lines replaces manual spreadsheet work, while traceable calculations support external assurance. Named support contacts and hands-on onboarding are offered as a lower-cost alternative to large consulting firms.

Mandatory ISSB-aligned climate disclosure is being phased in across Asia-Pacific, including Australia, Singapore and Malaysia, and Vietnam is preparing its own ESG reporting roadmap. Companies need audit-grade emissions data rather than estimates, which favours tools that link ERP data directly to calculations.
