CHENNAI EXPRESS against its type
Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 73,934 gross tonnage it is larger than 64% 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 PUCON for 2018, RDO CONCEPTION for 2019 and CHENNAI EXPRESS for 2022–2025. The reported port of registry changed: Majuro (2018), then Monrovia (2019–2025).
Its 40,113 t of CO₂ for 2025 is 2.5 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 570.0 kg CO₂, close to the type median of 545.6 kg. It logged 5,136 hours at sea against a median of 3,155 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2025 (40,113 t) and the lowest 2019 (10,634 t). Its efficiency percentile within the type went from 39 in 2018 to 43 in 2025 (lower is more efficient). Of the 3 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 791 of 1,838 qualifying container ships by EEOI, at the 43rd percentile. The dashed line is the type median, 14.2; this vessel reported 12.4.
EEOI divides emissions by transport work, which for this vessel and year was 3,240,156,704 tonne-miles over 70,373 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 62.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2024 to 2025, emissions rose 5.9% while distance sailed rose 19.6%and CO₂ per nautical mile fell 11.5%.That points mainly to how much the vessel sailed, rather than the other.
