To become an RSB member there are a few simple steps.

  1. Review our Membership Guide and Complete the Application Form.
  2. Write a Cover Letter. You may use the template included in the guide on page 9, or create your own as long as it includes:
  • A brief description of your organisation’s biofuel/biomaterial-related activities.
  • An acknowledgement that your organisation accepts the RSB’s Articles of Association and other official RSB documents and decisions (in other words the RSB standard and decisions of the RSB governing bodies).
  • A declaration of any conflict of interests you are aware of, or statement that none exist.
  • And, if you are applying for a fee waiver, your organisation’s most recent financial statements.

Applications must be reviewed and accepted by the RSB Board of Directors. This process can take up to 3 weeks from date of receipt. We accept applications on a rolling basis, and we look forward to welcoming you!


Should you have any questions regarding membership, your application, etc., please feel free to contact us at or +41 22 534 97 33.

We appreciate your support in advancing our mission of ensuring biomaterial sustainability across the globe!


By accepting the Articles of Association of the RSB, members endorse RSB objectives and commit to allocate sufficient time and resources towards the development and implementation of the RSB Standard.
RSB membership, however, does not indicate compliance with the RSB Principles & Criteria. Compliance with the RSB Principles & Criteria may only be demonstrated via certification, including the successful completion of an on-site audit by an accredited certification body, as defined in the RSB certification standards.
