NAPA FLEET INTELLIGENCE FOR MERCHANT SHIPS
Emission Compliance
Review and simulate your fleet’s compliance with CII, EU ETS, and FuelEU Maritime – all in one place, with full visibility and control.
One place for all your emissions compliance needs
With increasing pressure from CII, EU ETS, and FuelEU Maritime, staying compliant is more critical — and more complex — than ever. NAPA’s Emission Compliance module brings everything together in one platform, helping you monitor, report, and simulate your fleet’s compliance status in real time.
Under the EU ETS, shipping companies must surrender allowances for 100% of their emissions from 2027 onwards, based on emissions reported from 2026. The regulation applies to all ships over 5,000 GT calling at EU ports, covering 100% of intra-EU voyages and 50% of international legs. At the same time, CII ratings are pushing operators to continuously improve their vessel efficiency, while FuelEU Maritime will introduce greenhouse gas intensity limits for energy used on board.
As regional and global regulations tighten, proactive compliance is fast becoming a commercial imperative.
