The Roundtable on Sustainable Biomaterials (RSB) is a global membership organisation that drives the just and sustainable transition to a bio-based and circular economy. RSB’s sustainability framework is a globally-recognised, trusted and peer-reviewed foundation for supporting innovative solutions to the climate crisis, and has been collaboratively developed by its multi-stakeholder membership community – a diverse range of organisations across multiple supply chains, regions and industries that are lighting the way for a global sustainability movement. Underpinned by the RSB Principles & Criteria, RSB uses this foundation to develop projects, new knowledge and solutions that equip key decision-makers to deliver positive impacts for people and the planet.

ISEAL Code Compliant organisations have successfully adhered to our previous Codes of Good Practice (Standard-Setting, Impacts and Assurance) and have committed to aligning their systems to the ISEAL Code. Independent evaluations against the ISEAL Code commenced in October 2025, and organisations must demonstrate full adherence to the ISEAL Code by October 2029 to maintain their ISEAL Code Compliant status.
Please note, all ISEAL Code Compliant members are also ISEAL Community Members.
The ISEAL Code came into effect on 1 March 2024. Organisations that had adhered to the previous Codes of Good Practice were granted an 18-month transition period to align their system(s) with the ISEAL Code. For further information, visit: What is ISEAL Code Compliant.
From October 2025, independent evaluations against the ISEAL Code will commence in accordance with the Independent Evaluation Procedure. ISEAL Code Compliant organisations are required to successfully close an evaluation across the full scope of the ISEAL Code. This can be done through a single, full-scope evaluation or through phased specific-scope evaluations. Evaluations must be completed within four years of the end of the transition period, no later than October 2029, to maintain ISEAL Code Compliant status.
Details on the evaluation schedule will be made publicly available.
As a result of this independent evaluation, RSB has made the following improvements to how they set their standards:
- Updated their website to ensure that paper-copies of their standard are available upon request.
As a result of this independent evaluation, RSB has made the following improvements to their assurance system:
- Updated their Certification Standard Operating Procedure to ensure that monitoring activities are in place for suspended customers or for investigating misuse of the RSB logo.
- Updated the RSB Procedure for Certification Bodies and Auditors to clearly state that certification decisions may not be outsourced
- Updated the Assurance Standard Operating Procedure to indicate where documents are stored.
As a result of this independent evaluation, RSB identified the following improvements needed to their M&E system:
- Identify and measure any potential unintended negative effects of their standard
This improvement was assessed in 2024 by ISEAL as part of an assessment against the ISEAL Code and will be validated through independent evaluation in 2026.
ISEAL Code Compliant members provide publicly available reports that give a comprehensive and accessible overview of a member's system.
