TIVY GOLD against its type
Built in 2003, it is 7 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,063 gross tonnage it is larger than 58% 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 VALLERMOSA for 2018–2021 and TIVY GOLD for 2024–2025. The reported port of registry changed: Trieste (2020–2021), then MONROVIA (2024–2025).
Its 7,964 t of CO₂ for 2025 is 44% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 350.3 kg CO₂, 40% above the type median of 250.2 kg. It logged 2,011 hours at sea against a median of 2,106 hours for its type that year. 8.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2020 (14,816 t) and the lowest 2024 (7,156 t). Its efficiency percentile within the type went from 90 in 2020 to 42 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 568 of 1,348 qualifying chemical tankers by EEOI, at the 42nd percentile. The dashed line is the type median, 14.4; this vessel reported 13.0.
EEOI divides emissions by transport work, which for this vessel and year was 612,144,504 tonne-miles over 22,735 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 36.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 11.3% while distance sailed rose 5.1%and CO₂ per nautical mile rose 5.9%.
