KARLSKRONA against its type
Built in 1996, it is 12 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 81,488 gross tonnage it is larger than 68% 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 64 other vessels here, 53 of them container ships. Its MRV returns name it MAERSK KARLSKRONA for 2019–2022 and KARLSKRONA for 2023–2024. The returns for 2019–2024 all give MONROVIA as port of registry.
Its 18,840 t of CO₂ for 2024 is close to the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 713.8 kg CO₂, 35% above the type median of 528.5 kg. It logged 1,834 hours at sea against a median of 3,325 hours for its type that year. 2.4% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 6 years with reported emissions, the highest was 2021 (50,888 t) and the lowest 2023 (17,915 t). Its efficiency percentile within the type went from 39 in 2019 to 47 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 778 of 1,661 qualifying container ships by EEOI, at the 47th percentile. The dashed line is the type median, 15.4; this vessel reported 14.5.
EEOI divides emissions by transport work, which for this vessel and year was 1,299,342,759 tonne-miles over 26,394 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 3.5% higher than in 2019, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 5.2% while distance sailed rose 9.2%and CO₂ per nautical mile fell 3.7%.That points mainly to how much the vessel sailed, rather than the other.
