About the Webinar 

Continuous improvement is core to RSB’s mission — and that commitment extends to every part of our work, including RSB’s Book & Claim System. As the sustainability landscape evolves, so too must our frameworks. That’s why we’re updating our approach to Additionality.

Join us for a deep dive into the latest update to RSB’s Book & Claim System, where we unveil a more flexible, transparent, and market-enabling framework for assessing Additionality. 

Historically, RSB’s approach to Additionality has been deliberately conservative: only fuels that went beyond regulatory mandates were permitted in the system. In response to extensive stakeholder feedback, we’re introducing a new model that embraces transparency, reflects market realities, and empowers users to assign value based on clearly disclosed information. 

In this session, we’ll explore: 

• What’s changing in RSB’s Additionality requirements — and why now 

• How the new 4-category framework works (with real examples) 

• What this means for system users 

• How trust is built through full disclosure, not exclusion 

• Perspectives from across the market  

Whether you’re an RSB member, Book & Claim user, or a stakeholder in the sustainable fuel ecosystem, this is your chance to learn, question, and shape how we move forward together.
