EMERALD TOWER 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 95,390 gross tonnage it is larger than 77% 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 196 other vessels here, 17 of them container ships. MSC Shipmanagement is linked to 109 vessels on this register. Its MRV returns name it MSC ALGHERO for 2018–2024 and EMERALD TOWER for 2025. The reported port of registry changed: Panama (2018–2024), then Monrovia (2025).
Its 23,203 t of CO₂ for 2025 is 42% 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 964.2 kg CO₂, 1.8 times the type median of 545.6 kg. It logged 1,532 hours at sea against a median of 3,155 hours for its type that year. 5.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2020 (50,240 t) and the lowest 2024 (1,609 t). Its efficiency percentile within the type went from 22 in 2018 to 50 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 912 of 1,838 qualifying container ships by EEOI, at the 50th percentile. The dashed line is the type median, 14.2; this vessel reported 14.2.
Across the 102 ranked vessels operated by MSC Shipmanagement, the median percentile is 59. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 1,635,184,637 tonne-miles over 24,064 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 41.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 1,341.8% and CO₂ per nautical mile rose 7.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
