Research on the Implementation Path of Maritime Carbon Monitoring Systems

Abstract

With global shipping accelerating its transition toward low-carbon development, establishing a scientific and operable carbon monitoring system has become essential. Existing mechanisms such as the EU MRV and IMO DCS are shaping a shift from voluntary cooperation to rule-based competition. For China, a major shipping nation, simply adopting international frameworks cannot accommodate its diverse fleet, complex operations, and uneven digitalization. This study reviews key monitoring technologies—including BDN-based methods, tank level measurement, flowmeters, and direct CO₂ monitoring—and assesses their applicability within China. It further proposes an implementation pathway featuring multi-source data integration, digital governance, metrological traceability, differentiated monitoring strategies, and linkage with national carbon markets. The findings provide a framework to support accurate carbon accounting, regulatory compliance, and the sector’s green transition.
