HOEGH SYDNEY against its type
Built in 2007, it is 1 year older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 51,731 gross tonnage it is smaller than 73% 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 360 other vessels here, 8 of them vehicle carriers. Its MRV returns name it HOEGH SYDNEY for 2018–2024 and VIKING SYDNEY for 2025. The reported port of registry changed: Panama (2018–2024), then MAJURO (2025).
Its 4,184 t of CO₂ for 2025 is 41% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 335.6 kg CO₂, close to the type median of 309.1 kg. It logged 850 hours at sea against a median of 1,639 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 6 years with reported emissions, the highest was 2018 (20,143 t) and the lowest 2025 (4,184 t). Its efficiency percentile within the type went from 61 in 2018 to 76 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 320 of 423 qualifying vehicle carriers by EEOI, at the 76th percentile. The dashed line is the type median, 51.7; this vessel reported 74.3.
EEOI divides emissions by transport work, which for this vessel and year was 56,329,608 tonne-miles over 12,464 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 79.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 55.7% while distance sailed fell 54.3%and CO₂ per nautical mile fell 2.9%.That points mainly to how much the vessel sailed, rather than the other.
