ENDURANCE against its type

Built in 1996, it is 6 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 72,708 gross tonnage it is larger than 99% of the other 269 ro-ro ships with a recorded tonnage. It is the only ro-ro ship on this register under the United States flag. The same builder is recorded for 38 other vessels here. The returns for 2018–2025 all give Wilmington, DE as port of registry.

Its 14,425 t of CO₂ for 2025 is 32% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 371.2 kg CO₂, 14% above the type median of 327.0 kg. It logged 2,742 hours at sea against a median of 4,872 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2022 (33,560 t) and the lowest 2025 (14,425 t). Its efficiency percentile within the type went from 79 in 2018 to 38 in 2025 (lower is more efficient). Of the 8 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 74 of 192 qualifying ro-ro ships by EEOI, at the 38th percentile. The dashed line is the type median, 85.3; this vessel reported 74.7.

EEOI divides emissions by transport work, which for this vessel and year was 193,079,507 tonne-miles over 38,858 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 42.0% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 35.8% while distance sailed fell 39.5%and CO₂ per nautical mile rose 6.2%.That points mainly to how much the vessel sailed, rather than the other.
