Reported CO₂ in 2025 was 1,080.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions rose 133.9% and CO₂ per nautical mile rose 4.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 6 MRV reporting years, 4 of 5 vessel particulars and a name history. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
