Avarni

Avarni is a carbon accounting platform, founded in Australia, that focuses on supply chain emissions and on helping organisations mobilise their suppliers to reduce them. For most companies, the largest share of their footprint sits in Scope 3, which arises from purchased goods and services and other value chain activities outside direct control. These emissions are difficult to measure accurately, and reduction requires cooperation from suppliers who may themselves lack carbon expertise. Avarni tackles this challenge by combining emissions measurement with structured supplier engagement, enabling companies to replace generic spend-based estimates with more specific supplier data over time. Its approach links measurement directly to action, so that net zero commitments can be translated into practical reduction plans and tracked progress rather than remaining high-level targets without an operational pathway. The platform is designed to be usable by procurement and operations teams as well as sustainability specialists, broadening ownership of climate targets across the business.

The platform supports calculation of Scope 1, 2 and 3 emissions, using spend, activity and supplier-specific data, with AI-assisted categorisation of procurement and financial records to speed up the initial footprint. Supplier engagement tools allow companies to invite vendors to share emissions data, track their participation and progress, and identify which suppliers contribute most to the overall footprint. Reduction planning features help model the impact of initiatives such as switching suppliers or materials, and decarbonisation pathways can be tracked against science-based targets. Reporting capabilities support disclosures aligned with frameworks such as the Greenhouse Gas Protocol and emerging climate reporting standards in Australia and elsewhere. Avarni is cloud-based and aimed at mid-sized and large organisations in sectors such as construction, property, manufacturing, retail and professional services, where supply chain emissions dominate and procurement teams play a central role in decarbonisation efforts.
