Review and revision
The ISEAL Code of Good Practice for Sustainability Systems (‘the ISEAL Code’) v1.0 came into effect on 1 March 2024, followed by an 18-month transition period for ISEAL Code Compliant organisations to align their systems to the ISEAL Code.
About the review and revision process
The ISEAL Code of Good Practice for Sustainability Systems (‘the ISEAL Code’) is reviewed every four years. The next review will take place no later than March 2028.
ISEAL’s Technical Committee are responsible for oversight of the revision process, including the decision of whether a revision to the ISEAL Code is needed. Outside of the review and revision cycle, editorial and non-substantive changes can be made at any time when identified as necessary, with input from ISEAL’s Technical Committee.
The ISEAL Code v1.1
The ISEAL Code v1.1 is a minor update which includes editorial and non-substantive changes that improve the clarity and intent of requirements. It was published and came into effect from September 2025.
The changes do not affect the performance levels or expectations for compliance, and instead aim to address three objectives:
To provide greater clarity on requirements relevant to remediation
To improve consistency with ISEAL’s guidance on structuring data sharing and licensing agreements and chain of custody models and definitions
To provide additional guidance and editorial improvements
