AA1000 Sustainability Assurance
Independent assurance of your sustainability report — conducted entirely online. Evaluate adherence to AccountAbility Principles, verify performance data, and receive a formal assurance statement. Remote delivery enables a lower cost structure than traditional on-site engagements.
What is AA1000 Assurance?
AA1000AS v3 is the global standard for sustainability assurance, issued by AccountAbility. It evaluates how well your organisation identifies, prioritises, responds to, and measures the impact of its sustainability commitments.
Principles-Based Approach
Unlike financial audit standards, AA1000 takes a principles-based approach — assessing the quality of your sustainability management, stakeholder engagement, and reporting processes. The focus is on whether your organisation genuinely integrates sustainability, not just whether the numbers add up.
SEBI & BRSR Compatible
SEBI-mandated companies can use AA1000 alongside ISAE 3000 for BRSR Core assurance. AA1000 provides the principles-based framework that complements the data-focused ISAE approach — giving stakeholders confidence in both your processes and your numbers.
Four Principles We Assess
Every engagement evaluates your organisation against the four AccountAbility Principles — the foundation of credible sustainability management.
Inclusivity
Are your stakeholders genuinely involved in decision-making? We assess identification, mapping, engagement channels, documentation, and whether feedback actually influences strategy.
Materiality
Have you identified what truly matters? We evaluate your materiality assessment process, double materiality consideration, topic coverage, and boundary definitions.
Responsiveness
Are you acting on what matters? We examine policies, targets, KPIs, progress disclosure, grievance mechanisms, and governance oversight of sustainability responses.
Impact
Are you measuring real outcomes? We assess impact methodology, quantitative metrics, stakeholder-disaggregated data, and whether impact evidence informs future strategy.
