In 2013, ISEAL launched the Credibility Principles, which provide an international reference for defining the foundations of credible practices for sustainability standards.

We developed the Credibility Principles through an extensive global consultation with the guidance of an international multi-stakeholder Steering Committee.

In 2019, we carried out a review of the Credibility Principles. It explored how the how the principles have been used and adopted, the best approach to communicating the principles to meet stakeholder needs, changes in the landscape and trends, as well as their usability, scope and objectives.

The findings of the review informed the ISEAL Technical Committee’s decision to revise the Credibility Principles in 2020.

Through the revision, we are updating the principles to reflect current and future trends affecting standards and similar systems. We are also expanding their scope beyond sustainability standards to include a wider range of systems, such as data-driven and landscape approaches.
