MAERSK EDWARD against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 26,659 gross tonnage it is larger than 62% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 160 other vessels here, 8 of them chemical tankers. Its MRV returns name it MAERSK EDWARD for 2018–2019 and TONDA for 2023–2025. The reported port of registry changed: Kobenhavn (2018–2019), then Majuro (2023–2025).
Its 7,840 t of CO₂ for 2025 is 42% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 373.3 kg CO₂, 49% above the type median of 250.2 kg. It logged 1,920 hours at sea against a median of 2,109 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2019 (14,858 t) and the lowest 2024 (7,697 t). Its efficiency percentile within the type went from 89 in 2018 to 52 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 701 of 1,348 qualifying chemical tankers by EEOI, at the 52nd percentile. The dashed line is the type median, 14.4; this vessel reported 14.9.
EEOI divides emissions by transport work, which for this vessel and year was 525,125,921 tonne-miles over 21,004 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 43.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 1.9% while distance sailed rose 0.2%and CO₂ per nautical mile rose 1.6%.That points mainly to how efficiently it sailed, rather than the other.
