Book & Claim 101: How we’re building trust to scale the future of sustainable aviation
As sectors like aviation and shipping race to decarbonise, one challenge remains persistent: how can we connect sustainable fuel supply with global demand when physical delivery isn’t always possible?
That’s where ‘Book & Claim’ comes in.
This innovative chain-of-custody model allows the environmental attributes of sustainable aviation fuel (SAF) to be decoupled from its physical movement, enabling buyers to claim the climate benefits, even when fuel is used elsewhere. The model is vital for overcoming geographic, logistical, and production barriers, especially in hard-to-abate sectors.
But credibility is critical. Without strong rules and oversight, Book & Claim risks losing the trust that makes it powerful.
That’s why the Roundtable on Sustainable Biomaterials (RSB) has built a robust, transparent Book & Claim system, co-developed with our multistakeholder membership community and expert stakeholders from industry, civil society and academia – designed to ensure traceability, integrity, and real climate impact.
At this year’s Sustainable Aviation Futures North American Congress, RSB’s Associate Director of Digital Solutions and Book & Claim, Max Eichelbaum, will join the panel Book & Claim, Trust & Trade: Building Market Integrity Without Molecules, a timely conversation as momentum around this model continues to grow.
Recent milestones from RSB include:
Over 100 retirement statements issued via the RSB Book & Claim Registry since launch
RSB Book & Claim Manual v4 published, improving usability and market transparency
Recognition Procedure for an ecosystem of trusted registries
First registered co-processed fuel with SkyNRG
New Facilitator Account pilot with Airbus to simplify market access
With this system, RSB is not just supporting carbon claims, it’s unlocking market access, reducing Scope 3 emissions, and accelerating global SAF adoption.
