CHEMTRANS NOVA: CO₂ emissions 2019–2025

CHEMTRANS NOVA against its type

Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,167 gross tonnage it is smaller than 63% of the other 2,841 oil tankers with a recorded tonnage. It is one of 8 oil tankers here under the Antigua and Barbuda flag, 0.2% of the 3,548 on the register. The reported port of registry changed: Limassol (2019–2021), then St. John's (2024–2025).

Its 4,920 t of CO₂ for 2025 is 38% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 364.1 kg CO₂, close to the type median of 403.2 kg. It logged 1,159 hours at sea against a median of 2,030 hours for its type that year. 12.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2025 (4,920 t) and the lowest 2021 (2,518 t). Its efficiency percentile within the type went from 38 in 2019 to 86 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,239 of 1,448 qualifying oil tankers by EEOI, at the 86th percentile. The dashed line is the type median, 7.5; this vessel reported 14.6.

EEOI divides emissions by transport work, which for this vessel and year was 337,901,099 tonne-miles over 13,514 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 1.8% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.

From 2021 to 2025, emissions rose 95.4% while distance sailed rose 198.3%and CO₂ per nautical mile fell 34.5%.That points mainly to how much the vessel sailed, rather than the other.
