EVA HERON against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 20,145 gross tonnage it is smaller than 55% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The same builder is recorded for 307 other vessels here, 98 of them chemical tankers. Its MRV returns name it EVA HERON for 2018 and PACIFIC STAR for 2019–2025. The reported port of registry changed: Manila (2018), then Singapore (2019–2025).
Its 3,117 t of CO₂ for 2025 is 44% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 244.5 kg CO₂, close to the type median of 250.2 kg. It logged 1,226 hours at sea against a median of 2,106 hours for its type that year. 2.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2019 (14,951 t) and the lowest 2025 (3,117 t). Its efficiency percentile within the type went from 79 in 2018 to 70 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 939 of 1,348 qualifying chemical tankers by EEOI, at the 70th percentile. The dashed line is the type median, 14.4; this vessel reported 20.6.
EEOI divides emissions by transport work, which for this vessel and year was 151,389,995 tonne-miles over 12,747 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 16.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions fell 68.3% while distance sailed fell 62.8%and CO₂ per nautical mile fell 14.7%.That points mainly to how much the vessel sailed, rather than the other.
