CMA CGM TOKYO against its type

Built in 2013, it is 5 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 69,809 gross tonnage it is larger than 62% of the other 3,000 container ships with a recorded tonnage. It is one of 336 container ships here under the Malta flag, 9.6% of the 3,495 on the register. The same builder is recorded for 74 other vessels here, 49 of them container ships. Its MRV returns name it TOKYO BAY for 2020–2023 and CMA CGM TOKYO for 2024–2025. The reported port of registry changed: Monrovia (2020–2023), then VALLETTA (2024–2025).

Its 28,447 t of CO₂ for 2025 is 1.7 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 564.1 kg CO₂, close to the type median of 545.6 kg. It logged 4,378 hours at sea against a median of 3,155 hours for its type that year. 7.4% 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 (28,447 t) and the lowest 2020 (6,155 t). Its efficiency percentile within the type went from 29 in 2020 to 33 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 608 of 1,838 qualifying container ships by EEOI, at the 33rd percentile. The dashed line is the type median, 14.2; this vessel reported 10.5.

EEOI divides emissions by transport work, which for this vessel and year was 2,709,284,762 tonne-miles over 50,426 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 362.2% higher than in 2020, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 274.9% while distance sailed rose 254.5%and CO₂ per nautical mile rose 5.7%.That points mainly to how much the vessel sailed, rather than the other.
