SEAWAYS CITRON: CO₂ emissions 2018–2025

SEAWAYS CITRON against its type

Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,295 gross tonnage it is larger than 71% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it CITRON for 2018–2021, SEAWAYS CITRON for 2022–2024 and LILA KINGSTON for 2025. The reported port of registry changed: Hong Kong (2018–2024), then Monrovia (2025).

Its 5,939 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 315.2 kg CO₂, 26% above the type median of 250.2 kg. It logged 1,718 hours at sea against a median of 2,106 hours for its type that year. 6.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2021 (11,775 t) and the lowest 2020 (4,680 t). Its efficiency percentile within the type went from 11 in 2018 to 58 in 2025 (lower is more efficient). Of the 4 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 787 of 1,348 qualifying chemical tankers by EEOI, at the 58th percentile. The dashed line is the type median, 14.4; this vessel reported 16.6.

EEOI divides emissions by transport work, which for this vessel and year was 358,015,069 tonne-miles over 18,844 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 17.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions fell 40.1% while distance sailed fell 36.9%and CO₂ per nautical mile fell 5.2%.That points mainly to how much the vessel sailed, rather than the other.
