The five principles of assurance-ready carbon accounting

AASB S2 requires Scope 3 emissions to be measured using the GHG Protocol and independently assured. The Avarni × BDO methodology anchors every calculation in your financial and operational data, keeping it traceable and fully documented from source to disclosure.

Completeness

Data reconciled to the Trial Balance and General Ledger, with coverage checks across your emissions sources.

Consistency

Repeatable methodologies applied the same way across every reporting period.

Transparency

Clear audit trails and calculations you can trace back to the source.

Relevance

Materiality-led prioritisation, so effort goes where it matters most.

Accuracy

Progressive improvement from spend-based to activity-based data as your program matures.

Watch: a conversation with Aletta Boshoff, BDO in Australia

Aletta Boshoff, Partner and National Leader of IFRS & Corporate Reporting at BDO in Australia, has spent 30 years with accounting standards, and now helps organisations navigate mandatory climate disclosure under AASB S1 and S2. In this conversation she unpacks the pitfalls she sees most often: rushing to collect data before setting boundaries, and trusting technology that works like a black box. Her take on what assurance-ready really means is why Avarni and BDO built this partnership the way we did.
