We deliver independent third-party assurance for sustainability reports, GHG inventories, and GRESB Real Estate submissions, in accordance with AA1000AS v3 — available at both Type 1 and Type 2 assurance levels. Our assurance engagements serve listed corporates, asset managers, property developers, and financial institutions seeking credible, investor-grade verification of their ESG disclosures.
AA1000AS v3 Assurance
The AA1000 Assurance Standard v3 (AA1000AS v3) evaluates how effectively an organisation applies the AA1000 Accountability Principles: inclusivity, materiality, responsiveness, and impact. These principles support transparent, credible, and accountable sustainability reporting.
External assurance in accordance with AA1000AS v3 enables organisations to demonstrate strong governance and accountability, while providing stakeholders with greater confidence in the quality and credibility of sustainability information.
