CRUX LEADER against its type
Built in 1998, it is 10 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 57,449 gross tonnage it is smaller than 64% of the other 571 vehicle carriers with a recorded tonnage. It is one of 89 vehicle carriers here under the Liberia flag, 12.5% of the 713 on the register. The same builder is recorded for 323 other vessels here, 27 of them vehicle carriers. Its MRV returns name it GREEN RIDGE for 2018–2022 and CRUX LEADER for 2024–2025. The reported port of registry changed: Mobile, AL (2018–2021), then Mobile (2022), then MONROVIA (2024–2025).
Its 21,149 t of CO₂ for 2025 is 3.0 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 333.7 kg CO₂, close to the type median of 309.1 kg. It logged 4,053 hours at sea against a median of 1,639 hours for its type that year. 0.4% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 7 years with reported emissions, the highest was 2019 (25,442 t) and the lowest 2024 (2,146 t). Its efficiency percentile within the type went from 88 in 2018 to 86 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 364 of 423 qualifying vehicle carriers by EEOI, at the 86th percentile. The dashed line is the type median, 51.7; this vessel reported 93.5.
EEOI divides emissions by transport work, which for this vessel and year was 226,143,606 tonne-miles over 63,370 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 885.5% and CO₂ per nautical mile rose 18.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
