ARC HONOR against its type
Built in 2012, it is 4 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 72,295 gross tonnage it is larger than 92% of the other 571 vehicle carriers with a recorded tonnage. It is one of 23 vehicle carriers here under the United States flag, 3.2% of the 713 on the register. The same builder is recorded for 761 other vessels here, 18 of them vehicle carriers. Its MRV returns name it TULANE for 2018–2023 and ARC HONOR for 2024–2025. The reported port of registry changed: Valletta (2018–2023), then WILMINGTON, DE (2024–2025).
Its 6,854 t of CO₂ for 2025 is close to the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 389.8 kg CO₂, 26% above the type median of 309.1 kg. It logged 1,202 hours at sea against a median of 1,639 hours for its type that year. 6.9% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2018 (17,956 t) and the lowest 2024 (2,755 t). Its efficiency percentile within the type went from 12 in 2018 to 78 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 329 of 423 qualifying vehicle carriers by EEOI, at the 78th percentile. The dashed line is the type median, 51.7; this vessel reported 77.4.
EEOI divides emissions by transport work, which for this vessel and year was 88,530,225 tonne-miles over 17,582 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 61.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 148.8% while distance sailed rose 170.6%and CO₂ per nautical mile fell 8.1%.That points mainly to how much the vessel sailed, rather than the other.
