DEVBULK KAYA against its type

Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 23,857 gross tonnage it is larger than 90% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. Its MRV returns name it INDIGO MARCH for 2022 and DEVBULK KAYA for 2025. The reported port of registry changed: Panama (2022), then Majuro (2025).

Its 2,669 t of CO₂ for 2025 is close to the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 198.9 kg CO₂, 1.6 times the type median of 122.2 kg. It logged 1,347 hours at sea against a median of 3,044 hours for its type that year. 2.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Of the 7 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

EEOI divides emissions by transport work, which for this vessel and year was 439,571,798 tonne-miles over 15,160 nautical miles.

Reported CO₂ by year

2022: 3,398 t20223,3982025: 2,669 t20252,669

Reported CO₂ in 2025 was 21.4% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions fell 21.4% and CO₂ per nautical mile fell 11.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
