G2 Ocean rolls out book-and-claim service backed by biofuel voyages

Ship operator G2 Ocean on Wednesday (24 June) said it has launched Emission Reduction Certificates, a new service enabling customers to reduce emissions associated with their transportation services.

The service allows cargo owners and transport buyers to reduce their emissions from transportation by purchasing verified emission reductions generated from the use of biofuel in G2 Ocean’s operations.

The service is available to any company with emissions from transportation (Scope 3). It does not require cargo to be transported on specific low-emission G2 Ocean voyages.

For most companies, emissions from shipping are classified as indirect emissions (Scope 3) and sit outside their direct control. Reducing these emissions requires collaboration across the value chain.

Emission Reduction Certificates use a book-and-claim model, enabling customers to invest in emission reductions linked directly to maritime transport and to account for them in their climate reporting. The revenue will be reinvested in new biofuel voyages, helping create a cost-sharing model for biofuel and narrowing the gap between biofuel and regular fuel.

“Supply chain decarbonisation requires practical solutions. With our new service, Emission Reduction Certificates, customers can take immediate action to reduce their transport emissions while supporting the increased use of lower-emission fuels,” says Arthur English, Chief Executive Officer at G2 Ocean.

The emission reductions come from the use of certified biofuels on G2 Ocean voyages. They are verified and documented before being issued as digital certificates in a blockchain-connected registry. This registry tracks ownership and establishes a clear chain of custody for each certificate, ensuring that every certificate is unique and not double-counted or double-claimed.

“The certificates can be purchased and used by any company with emissions from transportation. The verified reductions are supported by audit documentation that enables credible climate reporting and emission accounting,” says Sigrid Bakken, ESG and Communications Director at G2 Ocean.

This ensures transparency, traceability and safeguards against double counting, providing customers with credible claims for decision-making, reporting and stakeholder communication.
