Avarni

Avarni is an Australian-owned carbon accounting software company headquartered in Sydney. Backed by CSIRO through Main Sequence Ventures, Avarni has spent the past four years helping organisations across diverse industries automate their greenhouse gas (GHG) management and reporting using advanced artificial intelligence (AI).

The platform uses AI to streamline every stage of the emissions accounting process - from data collection and analysis to regulatory-aligned reporting. This helps businesses meet compliance requirements with greater speed, accuracy and confidence. By replacing manual, spreadsheet-driven workflows with automation, Avarni reduces time and resource burdens - freeing teams to focus on strategic sustainability initiatives.

With proven experience in enterprise-scale and sector-specific reporting, Avarni supports clients in navigating evolving climate disclosure frameworks and achieving their decarbonisation goals. The technology adapts to different compliance regimes and integrates with existing systems - providing a flexible and future-ready solution.

Avarni is committed to equipping organisations with AI-powered tools and insights to not only meet their obligations but also lead in climate action - turning compliance into a catalyst for lasting environmental and business value.

Over the past four years, Avarni has enabled organisations across diverse industries to replace manual, spreadsheet-based processes with fully automated, AI-powered workflows.

The platform imports and transforms data from spreadsheets, PDF invoices or integrations with over 1,000 enterprise systems - including Oracle, SAP, Power BI and Pronto. Users can map columns, resolve data issues and customise entity structures and reporting categories. AI calculates emissions and matches them to over 65,000 up-to-date, audit-ready emission factors, with support for custom factor uploads.

Avarni also enables users to set and model net-zero targets by scope, year or emission source; compare reduction scenarios; and export compliance-ready reports with full traceability and audit support. Supplier engagement is streamlined through customisable surveys and free platform access.

With SOC 2 and ISO 27001 compliance and end-to-end encryption, Avarni delivers robust security while helping businesses meet today’s sustainability reporting requirements and prepare for future climate disclosure frameworks.
