ISTANBUL BRIDGE against its type
Built in 2000, it is 8 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 54,437 gross tonnage it is larger than 56% 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. The same builder is recorded for 761 other vessels here, 355 of them container ships. Its MRV returns name it OAKLAND EXPRESS for 2018–2022 and ISTANBUL BRIDGE for 2025. The reported port of registry changed: Hong Kong (2018–2022), then MONROVIA (2025).
Its 3,234 t of CO₂ for 2025 is 80% 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 558.8 kg CO₂, close to the type median of 545.6 kg. It logged 391 hours at sea against a median of 3,155 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2018 (28,381 t) and the lowest 2022 (1,799 t). Its efficiency percentile within the type went from 41 in 2018 to 46 in 2021 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 88.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 79.7% and CO₂ per nautical mile rose 27.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
