Nine maritime companies to develop ‘book and claim’ decarbonisation approaches

Nine maritime companies have signed a joint statement committing to developing and implementing ‘book and claim’ chain of custody systems, aiming to accelerate the early phases of shipping’s decarbonisation.

In a book and claim system, the environmental benefits of zero- and near zero-emission fuels are tracked and transferred across the maritime value chain.

One party can purchase, or “book”, a specific quantity of zero- or near zero-emission fuel and then “claim” the environmental benefits of it even though the fuel is physically used by another shipper in a different location.
