GREEN LAKE 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 57,623 gross tonnage it is smaller than 61% 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 307 other vessels here, 55 of them vehicle carriers. Its MRV returns name it GREEN LAKE for 2020 and VELA LEADER for 2025.
Its 2,025 t of CO₂ for 2025 is 71% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 288.3 kg CO₂, close to the type median of 309.1 kg. It logged 532 hours at sea against a median of 1,639 hours for its type that year. 7.8% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Of the 4 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 85 of 423 qualifying vehicle carriers by EEOI, at the 20th percentile. The dashed line is the type median, 51.7; this vessel reported 39.3.
EEOI divides emissions by transport work, which for this vessel and year was 51,536,641 tonne-miles over 7,026 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 38.7% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions fell 38.7% and CO₂ per nautical mile fell 22.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
