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).

SAF is currently produced and supplied in 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 also their corporate customers who wish to decrease emissions from business travel.

Book & 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 & 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 ‘credit’. 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 & Claim certification approach that we are currently piloting with SAF transactions.

RSB's Book & Claim Approach

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

    RSB has developed a Book & Claim System consisting of:

    • The Book & Claim Manual, which is a procedure describing the rules which allow a company to register, trade and retire credits in the RSB Book and Claim system.
    • The Book & Claim Registry, which is a system to store Book & 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 & Claim, the net environmental effect is the same.

  • Who are the key partners?

    RSB is currently piloting Book & Claim in collaboration with Airbp, and other partners including United Airlines and Microsoft, and we are designing further pilots in both the aviation and shipping sectors.

    RSB is also working with the Sustainable Aviation Buyers Alliance (SABA), a joint initiative of Environmental Defense Fund (EDF) and RMI on the development of an electronic registry to support the uptake of book & claim at a larger scale.

    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?

    We are currently running a stakeholder consultation on the RSB Book & Claim Manual that will run until Friday 25 February 2022. Click here for more info on how to participate.
