HOEGH MAPUTO against its type
Built in 2011, it is 3 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 47,266 gross tonnage it is smaller than 77% of the other 571 vehicle carriers with a recorded tonnage. It is one of 6 vehicle carriers here under the Greece flag, 0.8% of the 713 on the register. The same builder is recorded for 41 other vessels here, 22 of them vehicle carriers. Its MRV returns name it HOEGH MAPUTO for 2018–2021 and NEPTUNE THARROS for 2022–2025. The reported port of registry changed: Oslo (2018–2021), then Piraeus (2022–2025).
Its 17,777 t of CO₂ for 2025 is 2.5 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 276.2 kg CO₂, 11% below the type median of 309.1 kg. It logged 5,246 hours at sea against a median of 1,639 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2022 (20,769 t) and the lowest 2020 (10,787 t). Its efficiency percentile within the type went from 70 in 2018 to 88 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 373 of 423 qualifying vehicle carriers by EEOI, at the 88th percentile. The dashed line is the type median, 51.7; this vessel reported 101.7.
EEOI divides emissions by transport work, which for this vessel and year was 174,870,450 tonne-miles over 64,371 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 2.4% while distance sailed rose 8.4%and CO₂ per nautical mile fell 5.6%.That points mainly to how much the vessel sailed, rather than the other.
