CELSIUS PORTO against its type

Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 30,241 gross tonnage it is smaller than 70% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 192 other vessels here, 71 of them oil tankers. Its MRV returns name it CELSIUS PORTO for 2018–2020 and CHARLINE for 2024–2025. The returns for 2018–2025 all give Majuro as port of registry.

Its 3,173 t of CO₂ for 2025 is 60% 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 317.5 kg CO₂, 21% below the type median of 403.2 kg. It logged 912 hours at sea against a median of 2,030 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2019 (9,877 t) and the lowest 2025 (3,173 t). Its efficiency percentile within the type went from 67 in 2018 to 65 in 2025 (lower is more efficient). Of the 7 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 940 of 1,448 qualifying oil tankers by EEOI, at the 65th percentile. The dashed line is the type median, 7.5; this vessel reported 8.8.

EEOI divides emissions by transport work, which for this vessel and year was 359,761,905 tonne-miles over 9,994 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 41.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions fell 9.7% while distance sailed fell 0.5%and CO₂ per nautical mile fell 9.3%.That points mainly to how efficiently it sailed, rather than the other.
