FAQ
Can I use Excel + auditor for Group 1?
For very limited disclosure scope, yes — but the assurance + audit-ready trail becomes hard once Scope 3 + supplier engagement scale.
Do Group 2 + 3 entities need to start now?
Yes — Group 2 commences FY27, Group 3 FY28. NGER alignment + supplier engagement take 12-18 months to mature.
