Driving rapid decarbonisation with innovative chain of custody solutions

Book & Claim

Buyers and end-users globally are increasingly demanding sustainable products and materials but cannot always access them via their existing supply chain network. This is the case, for example, for Sustainable Aviation Fuels (SAF), which is currently produced and supplied in only a few countries and airports – meaning that it is often out of reach for the growing number of customers globally (including not only airlines, but their corporate customers too who may wish to decrease their emissions from business travel).

‘Book and claim’ is a solution that enables airlines to purchase SAF without being geographically connected to a supply site, and to further transfer its sustainability attributes to their corporate partners. Technically speaking, ‘book and claim’ is a chain of custody model that allows to ‘de-couple’ specific attributes, like for example the environmental benefits, from the physical product and to transfer them separately via a dedicated registry in the form of a ‘Book & Claim Unit’. This approach has been already successfully implemented in the renewable electricity sector (see here).

Ensuring that there is full traceability and no risk of double counting is absolutely vital to maintain credibility and trust in the process. This means that producers and customers should be using a system that is managed by an independent and trusted third party and is subject to regular independent audits. In close collaboration with stakeholders and industry experts, RSB has developed a ‘book and claim’ certification approach that we are currently piloting.

RSB's Book & Claim Approach

The RSB Book & Claim System aims to accelerate decarbonisation efforts across sectors, and to promote the production and use of sustainably certified fuels and materials. The system is currently focusing on the famously hard-to-abate sectors of aviation and shipping, and aims to address the key challenges of cost, given that sustainable aviation and marine fuels are still considerably more expensive than fossil fuels, and the limited amount of supply sites vis-à- vis growing global interest and demand. The RSB Book & Claim System provides a robust and transparent approach to decouple and transfer the environmental benefits of sustainable aviation and marine fuels via book and claim’, and allows multiple entities to share a claim, such as the emission reduction, provided they report within relevant GHG scopes and according to the requirements of this manual.

 

It was developed to promote in-sector decarbonisation, and as such, enable organisations to invest in emission reductions within their value chains and link them to the organisation’s actual transport activity (i.e. SAF-related reductions linked to the company’s actual air transportation-related emissions)¹, as well as meet the requirements of the Science Based Targets Initiative’s (SBTi) Aviation Guidance². The RSB Book & Claim System has been designed, and is being continuously improved, through a series of stakeholder consultations and pilots. This has been described in the table below.

  • How does it work?
  • Who are the key partners?
  • How can I get involved?
  • How does it work?

    The RSB Book & Claim System consists of:

    • The RSB Book & Claim Manual, which is a procedure describing the rules which allow a company to register, transfer and retire credits in the RSB Book and Claim System.
    • The RSB Book & Claim Registry, which is a system to store ‘book and claim’ transaction data.

    The RSB Book & Claim System aims to ensure that for each claim made on a book & claim basis, products with the same specified characteristics have been produced and double claiming of the environmental benefit of those products is avoided at all times. Ultimately, no matter where the product is purchased and used via ‘book and claim’, the net environmental effect is the same. 

  • Who are the key partners?

    RSB is currently piloting Book & Claim in collaboration with several aviation partners, including: Airbp, United Airlines and Microsoft, Singapore Airlines, Etihad, TotalEnergies, Shell and the Sustainable Aviation Buyers Alliance (SABA) and we are designing further pilots in both the aviation and shipping sectors.

     

    RSB is also an advisory member of the World Economic Forum’s Clean Skies for Tomorrow, supporting the development of mechanisms based on book & claim to facilitate the transition to net-zero flying by 2050.

  • How can I get involved?

    RSB members are invited to participate in the stakeholder consultation of the RSB Book & Claim Manual v3.0 which runs until 19 September 2022, and to join us at the RSB Innovations Meeting in Boston on 5 October 2022 to discuss book & claim and US policy.
