HERCULES J against its type
Built in 2009, it is 1 year newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 10,585 gross tonnage it is smaller than 87% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Cyprus flag, 3.4% of the 3,495 on the register. The returns for 2018–2025 all give LIMASSOL as port of registry.
Its 26,599 t of CO₂ for 2025 is 1.6 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 262.6 kg CO₂, 52% below the type median of 545.6 kg. It logged 6,489 hours at sea against a median of 3,155 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2025 (26,599 t) and the lowest 2021 (11,205 t). Its efficiency percentile within the type went from 82 in 2018 to 98 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,794 of 1,838 qualifying container ships by EEOI, at the 98th percentile. The dashed line is the type median, 14.2; this vessel reported 54.4.
EEOI divides emissions by transport work, which for this vessel and year was 489,127,437 tonne-miles over 101,305 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 48.4% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 5.3% while distance sailed rose 7.6%and CO₂ per nautical mile fell 2.2%.That points mainly to how much the vessel sailed, rather than the other.
