Avarni

Avarni is the emissions management platform built for Australian finance teams facing mandatory ASRS and AASB S2 climate disclosure. Designed for CFOs, financial controllers, and sustainability leads at mid-market and enterprise organisations with mandatory reporting obligations. As mandatory climate reporting rolls out across Australia, Avarni gives finance teams the data infrastructure to measure, disclose, and reduce Scope 1, 2, and 3 emissions with confidence. With ASRS deadlines now in effect for large entities and phasing in for others, the pressure on finance teams to produce rigorous, auditable climate disclosures has never been greater. Avarni is built specifically to meet that challenge. Unlike generic ESG platforms built for a global market, Avarni is designed from the ground up for Australian compliance frameworks. The platform maps directly to AASB S2 / IFRS S2 disclosure requirements, so finance teams aren't left translating international standards into local obligations. Everything from data collection through to board-ready reporting is structured around what Australian regulators actually require. Why finance teams choose Avarni over generic ESG tools: ✅ Automated Scope 1, 2, and 3 emissions tracking across your operations and supply chain ✅ AASB S2-aligned reporting and scenario analysis, structured around Australian disclosure requirements, not adapted from overseas frameworks ✅ Supplier engagement tools to collect, verify, and audit upstream emissions data across your value chain ✅ Audit-ready outputs that meet the evidentiary standards your external auditors and board will expect ✅ Dashboard views built for both finance teams and board-level reporting, with the granularity CFOs need and the clarity boards require ✅ Integrations with over 1,000 enterprise tools, so Avarni fits into your existing financial systems rather than replacing them Integrations include: Microsoft Dynamics 365 · Oracle NetSuite · Salesforce · SAP · Xero · Pronto · Power BI · Workday · Q2 · and 990+ more Who uses Avarni: Avarni is used by CFOs, financial controllers, sustainability leads, and ESG reporting teams at Australian mid-market and enterprise organisations. It's particularly suited to organisations in their first or second year of ASRS reporting, where getting the data infrastructure right from the outset is critical, as well as finance teams managing complex supply chains with significant Scope 3 exposure. Trusted by ASX-listed and other leading Australian organisations including Latitude Financial, Hutchinson Builders, BDO Australia, CSL, Maersk, Pedal Group (99 Bikes), Cement Australia, Schneider Electric, Green by Nature, Kagome, Teys, Capricorn Financial, COG Financial Services, and Marubeni-Itochu Steel. What sets Avarni apart: Most emissions platforms were built for sustainability teams, not finance teams. That means data that's hard to audit, reporting that doesn't map to accounting standards, and outputs that create more work for finance rather than less. Avarni is different. Built with the rigour that finance teams expect: traceable data lineage, structured around AASB S2, and designed to produce outputs your auditors can actually work with. Avarni is SOC 2 Type II certified, giving finance teams and their IT and security stakeholders confidence that their data is handled to enterprise-grade standards. Avarni was named a Sustainability Leader by the Australian Financial Review (AFR) in 2023. Backed by leading Australian investors: Avarni is backed by Main Sequence (CSIRO Innovation Fund), AfterWork, Sprint, Common Sense, and Vulpes, investors who back category-defining Australian technology companies. Getting started: Avarni connects to your existing financial and procurement systems in days, not months. Implementation is guided by a team with deep expertise in both Australian climate regulation and financial reporting, so you're not navigating ASRS compliance alone. Avarni is built in Australia, for Australian reporting requirements.
