GREEN SPINEL against its type
Built in 2012, it is 2 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,840 gross tonnage it is larger than 85% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. Its MRV returns name it NAVIGARE PACTOR for 2018–2022 and GREEN SPINEL for 2023–2025. The reported port of registry changed: Skovshoved (2018–2022), then Valletta (2023–2025).
Its 15,422 t of CO₂ for 2025 is 2.8 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 381.3 kg CO₂, 1.5 times the type median of 250.2 kg. It logged 4,490 hours at sea against a median of 2,106 hours for its type that year. 15.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2023 (17,485 t) and the lowest 2020 (4,998 t). Its efficiency percentile within the type went from 37 in 2018 to 58 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 781 of 1,348 qualifying chemical tankers by EEOI, at the 58th percentile. The dashed line is the type median, 14.4; this vessel reported 16.3.
EEOI divides emissions by transport work, which for this vessel and year was 944,371,708 tonne-miles over 40,447 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 75.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 8.4% while distance sailed fell 8.8%and CO₂ per nautical mile rose 0.5%.That points mainly to how much the vessel sailed, rather than the other.
