123Carbon and ZERO44 have announced a strategic partnership aimed at linking the voluntary and mandatory carbon markets for shipowners, operators, and charterers.
The collaboration integrates 123Carbon’s carbon insetting registry with ZERO44’s SaaS platform for CO₂ management, allowing companies to allocate low-carbon fuel impacts either to regulatory compliance or voluntary carbon insetting, and to monitor vessel compliance in real time.
The combined system also enables users to assign specific fuel volumes for compliance or voluntary use, the companies note, avoiding double-counting.
ZERO44’s technology supports emission forecasting and compliance planning under frameworks such as FuelEU Maritime, the EU ETS, and the Carbon Intensity Indicator, while 123Carbon’s registry manages the issuance and allocation of Environmental Attribute Certificates across all transport modes following Book and Claim methodologies.
“For the first time, voluntary carbon trading opportunities are seamlessly combined with regulatory obligations under FuelEU, EU ETS, and CII, within a single platform,” said Frederike Hesse, Managing Director, at ZERO44.
“This integration provides our customers with full transparency, empowering them to make optimal decisions and secure a clear competitive advantage on their journey to net zero.”
