ISEAL Codes of Good Practice

We help sustainability systems to achieve their sustainability goals. 

ISEAL’s Codes of Good Practice provide a globally recognised framework, defining practices for effective and credible sustainability systems.

ISEAL’s Code Compliant members meet all three of our Codes of Good Practice, which focus on the core elements of a sustainability system: 

  • The ISEAL Standard-setting Code defines how a standard should be developed, structured and improved over time. The Code addresses multi-stakeholder consultation and decision-making, and ensures the standard contains clear requirements that can be measured and assessed.
  • The ISEAL Assurance Code provides a framework for assessing compliance with standards, so that consumers, supply chain partners, investors and other stakeholders know they can trust the results of assessments. It encourages assurance that is rigorous and accessible, providing accurate and transparent results.
  • The ISEAL Impacts Code supports robust monitoring and evaluation that helps systems to understand how effective their  standards are in achieving what they set out to do. It provides standards with a roadmap to measure progress against sustainability goals and to improve practices over time.

Upcoming consultation on ISEAL Code of Good Practice

We are currently preparing for the revision and integration of the ISEAL Impacts, Standard-Setting and Assurance Codes of Good Practice into one integrated Code of Good Practice.

We anticipate opening consultation on a first draft of the revised and integrated Code in September 2022. If you have any feedback or questions in the meantime, please contact Caitlin Peeling, Senior Manager for Membership and Services.

Please note that until the completion of the revision, information in the Codes' forewords on ISEAL membership is out of date since the introduction of our new membership structure

Additionally, in the Impacts and Standard-Setting Codes, Appendix A: Compliance Criteria is also outdated as, in line with our new membership structure, ISEAL Code Compliant members must demonstrate adherence to the baseline and improvement criteria of all three of ISEAL’s Codes of Good Practice. 

We welcome your feedback

ISEAL welcomes all stakeholders' comments to help improve our Codes of Good Practices.
