DELPHIS RIGA against its type
Built in 2017, it is 9 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 25,715 gross tonnage it is smaller than 71% of the other 3,000 container ships with a recorded tonnage. It is one of 202 container ships here under the Hong Kong flag, 5.8% of the 3,495 on the register. The same builder is recorded for 133 other vessels here, 105 of them container ships. The returns for 2018–2025 all give Hong Kong as port of registry.
Its 15,185 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 304.8 kg CO₂, 44% below the type median of 545.6 kg. It logged 4,118 hours at sea against a median of 3,155 hours for its type that year. 11.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2022 (18,847 t) and the lowest 2019 (11,399 t). Its efficiency percentile within the type went from 60 in 2018 to 67 in 2025 (lower is more efficient). Of the 4 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 1,225 of 1,838 qualifying container ships by EEOI, at the 67th percentile. The dashed line is the type median, 14.2; this vessel reported 19.1.
EEOI divides emissions by transport work, which for this vessel and year was 795,015,707 tonne-miles over 49,817 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 2.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 14.3% while distance sailed fell 11.4%and CO₂ per nautical mile fell 3.3%.That points mainly to how much the vessel sailed, rather than the other.
