SYNERGY ANTWERP against its type
Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 40,030 gross tonnage it is smaller than 56% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Marshall Islands flag, 3.4% of the 3,495 on the register. The same builder is recorded for 563 other vessels here, 243 of them container ships. The reported port of registry changed: Hong Kong (2018), then Majuro (2019–2025).
Its 23,487 t of CO₂ for 2025 is 44% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 386.3 kg CO₂, 29% below the type median of 545.6 kg. It logged 4,592 hours at sea against a median of 3,155 hours for its type that year. 0.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (35,723 t) and the lowest 2023 (7,780 t). Its efficiency percentile within the type went from 57 in 2018 to 38 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 704 of 1,838 qualifying container ships by EEOI, at the 38th percentile. The dashed line is the type median, 14.2; this vessel reported 11.4.
EEOI divides emissions by transport work, which for this vessel and year was 2,067,559,859 tonne-miles over 60,803 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 34.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 118.6% while distance sailed rose 102.8%and CO₂ per nautical mile rose 7.8%.That points mainly to how much the vessel sailed, rather than the other.
