Linking compliance and opportunity
Software developers 123Carbon from the Netherlands and ZERO44 from Germany have combined their cloud platforms to create a single workspace where ship owners, operators and charterers can track, forecast and allocate greenhouse gas performance. The collaboration arrives as FuelEU Maritime and the European Union Emissions Trading System begin to influence fuel strategies and voyage economics across fleets.
Unlocking dynamic allocation
Within the new portal, users assign each delivery of low carbon fuel to either the mandatory account needed for regulatory compliance or the voluntary account requested by forward thinking cargo customers. This capability removes the previous need for duplicate record keeping and unlocks an extra revenue stream because buyers who value Scope Three reductions can purchase the Environmental Attribute Certificates linked to specific voyages.
Less obvious benefit of book claim logic
By reserving certificates until freight contracts are finalised, operators avoid the risk of overcommitting limited green fuel volumes. This buffer effect turns spare emission reductions into a tradable asset rather than an administrative liability.
End to end visibility
ZERO44 brings predictive algorithms that estimate future carbon intensity indicators and ETS exposure, while 123Carbon supplies the secure registry for certificate issuance under recognised Book and Claim methodology. Together the tools display live fleet dashboards, automated journal entries for finance teams and API connections for forwarders. ESG managers gain immediate evidence for sustainability reports, and commercial departments can quote low carbon options with confidence. Importantly, the platform reconciles allocations across sea rail road and air legs, giving logistics chains one ledger for emissions. The cross modal view cuts audit time and places maritime data at the centre of enterprise climate planning.
Conclusion
The partnership between 123Carbon and ZERO44 shows how digital cooperation can turn regulatory complexity into commercial advantage. By merging forecasting, registry and trading functions, the service empowers shipping companies to monetise climate progress and steer confidently toward net zero targets.
