CMC ANTILLANCA against its type

It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. Its MRV returns name it STI SAN ANTONIO for 2018–2023 and CMC ANTILLANCA for 2024–2025. The reported port of registry changed: Majuro (2018–2023), then MONROVIA (2024–2025).

Its 8,079 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 293.0 kg CO₂, 27% below the type median of 403.2 kg. It logged 2,366 hours at sea against a median of 2,030 hours for its type that year. 5.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2023 (13,780 t) and the lowest 2021 (2,649 t). Its efficiency percentile within the type went from 60 in 2018 to 77 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 27.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.

From 2024 to 2025, emissions fell 37.1% while distance sailed fell 38.4%and CO₂ per nautical mile rose 2.1%.That points mainly to how much the vessel sailed, rather than the other.
