POLARIS PRINCESS against its type
Built in 1996, it is 12 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 9,827 gross tonnage it is smaller than 99% of the other 571 vehicle carriers with a recorded tonnage. It is one of 62 vehicle carriers here under the Marshall Islands flag, 8.7% of the 713 on the register. The same builder is recorded for 17 other vessels here, one of them a vehicle carrier. Its MRV returns name it VIKING PRINCESS for 2018–2023 and POLARIS PRINCESS for 2024–2025. The reported port of registry changed: Singapore (2018–2020), then Majuro (2021–2025).
Its 8,861 t of CO₂ for 2025 is 25% above the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 130.3 kg CO₂, 58% below the type median of 309.1 kg. It logged 5,764 hours at sea against a median of 1,639 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2025 (8,861 t) and the lowest 2018 (686 t). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 422 of 423 qualifying vehicle carriers by EEOI, at the 100th percentile. The dashed line is the type median, 51.7; this vessel reported 254.7.
EEOI divides emissions by transport work, which for this vessel and year was 34,793,977 tonne-miles over 67,986 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1,191.0% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 25.3% and CO₂ per nautical mile rose 9.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
