AA1000 Assurance Standard


Twenty years ago, sustainability was a business nonessential; a decade ago, a passive investment. Today, sustainability is responsible business practice.

With expectations higher than ever before, assurance has become a business necessity. And AccountAbility has developed the solution of choice for sustainability leaders seeking assurance of their sustainability management, performance, and reporting.

The AA1000 Assurance Standard (AA1000AS v3) is the leading methodology used by sustainability professionals worldwide for sustainability-related assurance engagements, to assess the nature and extent to which an organization adheres to the AccountAbility Principles.

The AA1000AS v3 is a next generation standard for sustainability assurance that:

  • Offers Principles-based Guidance rooted in the AA1000 Accountability Principles (2018) of Inclusivity, Materiality, Responsiveness, and Impact.
  • Incorporates a Wide-angle, Integrated, and Forward-looking view of a company’s overall sustainability management, performance, and reporting practices.
  • Ensures Flexibility, Accessibility, and Applicability by any organization, of any size, in any industry, anywhere in the world.
  • Prioritizes the User Experience to be easy to read, simple to use, and clear in its objectives.

The AA1000AS v3 will be administered through an innovative e-licensing system for AccountAbility-licensed assurance providers, which will be introduced in Fall 2020. Please check back soon for more information.

Until January 1, 2021, organizations that have transitioned to the AA1000AP (2018) seeking assurance must be assured by AccountAbility licensed assurance providers using the AA1000AS (2008) with 2018 Addendum. Organizations that have not yet transitioned to the AA1000AP (2018) and still use the AA1000AS (2008) may continue to use the AA1000AS (2008) – available below – for assurance purposes until 2021.
