BARBARA against its type

Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 52,726 gross tonnage it is larger than 54% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. Its MRV returns name it BARBARA for 2018–2020 and GSL TINOS for 2024–2025. The reported port of registry changed: Madeira (2018–2020), then Monrovia (2024–2025).

Its 4,370 t of CO₂ for 2025 is 73% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 429.5 kg CO₂, 21% below the type median of 545.6 kg. It logged 926 hours at sea against a median of 3,155 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2024 (20,323 t) and the lowest 2025 (4,370 t). Its efficiency percentile within the type went from 78 in 2018 to 58 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,063 of 1,838 qualifying container ships by EEOI, at the 58th percentile. The dashed line is the type median, 14.2; this vessel reported 16.4.

EEOI divides emissions by transport work, which for this vessel and year was 266,137,637 tonne-miles over 10,175 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 63.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions fell 78.5% while distance sailed fell 73.2%and CO₂ per nautical mile fell 19.7%.That points mainly to how much the vessel sailed, rather than the other.
