JANIS against its type
Built in 2009, it is the same age as the median vessel in the other ship types category on this register (build year 2009, 451 vessels with a known build year). At 9,611 gross tonnage it is smaller than 54% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 35 vessels in the other ship types category here under the Liberia flag, 7.0% of the 499 on the register. The same builder is recorded for 95 other vessels here, 15 of them vessels in the other ship types category. Its MRV returns name it OSLO FJORD 1 for 2018, JANIS for 2019–2023 and OCEAN7 ALGORA for 2025. The reported port of registry changed: Panama (2019–2022), then Monrovia (2023–2025).
Its 3,684 t of CO₂ for 2025 is 28% below the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 179.6 kg CO₂, 22% below the type median of 231.1 kg. It logged 1,730 hours at sea against a median of 2,231 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 7 years with reported emissions, the highest was 2019 (11,685 t) and the lowest 2022 (1,268 t). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 74 of 119 qualifying other ship typess by EEOI, at the 62nd percentile. The dashed line is the type median, 69.3; this vessel reported 86.1.
EEOI divides emissions by transport work, which for this vessel and year was 42,807,692 tonne-miles over 20,515 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 89.5% and CO₂ per nautical mile rose 41.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
