GH PARKS against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,006 gross tonnage it is larger than 89% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 65 chemical tankers here under the Hong Kong flag, 2.8% of the 2,344 on the register. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it MR PAT BROWN for 2019–2020, GH PARKS for 2021–2023 and PEACE ONE for 2025. The reported port of registry changed: Majuro (2021–2023), then Hong Kong (2025).
Its 1,217 t of CO₂ for 2025 is 78% 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 291.1 kg CO₂, 16% above the type median of 250.2 kg. It logged 367 hours at sea against a median of 2,109 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2023 (13,472 t) and the lowest 2025 (1,217 t). Its efficiency percentile within the type went from 88 in 2019 to 5 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 70 of 1,348 qualifying chemical tankers by EEOI, at the 5th percentile. The dashed line is the type median, 14.4; this vessel reported 7.2.
EEOI divides emissions by transport work, which for this vessel and year was 168,040,055 tonne-miles over 4,179 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 61.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 91.0% while distance sailed fell 87.9%and CO₂ per nautical mile fell 25.6%.That points mainly to how much the vessel sailed, rather than the other.
