ANTON against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 5,655 gross tonnage it is smaller than 95% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 12 chemical tankers here under the Gibraltar flag, 0.5% of the 2,344 on the register. Its MRV returns name it HEATHER for 2018–2021 and ANTON for 2022–2025. The reported port of registry changed: VALLETTA (2018–2021), then Gibraltar (2022–2025).
Its 4,466 t of CO₂ for 2025 is 19% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 155.8 kg CO₂, 38% below the type median of 250.2 kg. It logged 2,909 hours at sea against a median of 2,109 hours for its type that year. 11.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (8,123 t) and the lowest 2022 (4,465 t). Its efficiency percentile within the type went from 97 in 2018 to 93 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,249 of 1,348 qualifying chemical tankers by EEOI, at the 93rd percentile. The dashed line is the type median, 14.4; this vessel reported 39.5.
EEOI divides emissions by transport work, which for this vessel and year was 113,052,405 tonne-miles over 28,670 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 45.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 8.3% while distance sailed rose 7.9%and CO₂ per nautical mile fell 15.0%.That points mainly to how efficiently it sailed, rather than the other.
