GUDRUN MAERSK against its type
Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 98,648 gross tonnage it is larger than 78% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Denmark flag, 3.4% of the 3,495 on the register. The same builder is recorded for 64 other vessels here, 53 of them container ships. Maersk is linked to 8 vessels on this register. The returns for 2018–2025 all give Svendborg as port of registry.
Its 21,033 t of CO₂ for 2025 is 29% 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 845.4 kg CO₂, 1.5 times the type median of 545.6 kg. It logged 1,554 hours at sea against a median of 3,155 hours for its type that year. 0.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2025 (21,033 t) and the lowest 2018 (2,732 t). Its efficiency percentile within the type went from 22 in 2018 to 34 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 628 of 1,838 qualifying container ships by EEOI, at the 34th percentile. The dashed line is the type median, 14.2; this vessel reported 10.6.
Across the 7 ranked vessels operated by Maersk, the median percentile is 29. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 1,976,743,421 tonne-miles over 24,878 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 670.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 81.6% while distance sailed rose 61.3%and CO₂ per nautical mile rose 12.6%.That points mainly to how much the vessel sailed, rather than the other.
