THETAGAS against its type

Built in 2008, it is 5 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 9,110 gross tonnage it is smaller than 80% of the other 525 gas carriers with a recorded tonnage. It is one of 10 gas carriers here under the Antigua and Barbuda flag, 1.5% of the 688 on the register. The same builder is recorded for 96 other vessels here, 7 of them gas carriers. Its MRV returns name it THETAGAS for 2018–2021, THETAGAS (THETAGAS) for 2022 and THETAGAS for 2023–2025. The reported port of registry changed: Saint John's (2018–2021), then Saint John's (AG SJO) (2022), then Saint John's (2023–2025).

Its 7,975 t of CO₂ for 2025 is 34% above the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 238.3 kg CO₂, close to the type median of 256.2 kg. It logged 2,789 hours at sea against a median of 1,943 hours for its type that year. 11.2% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2020 (10,788 t) and the lowest 2022 (6,305 t). Its efficiency percentile within the type went from 87 in 2018 to 98 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.

Efficiency against its own type2025

Position 286 of 292 qualifying gas carriers by EEOI, at the 98th percentile. The dashed line is the type median, 27.9; this vessel reported 123.9.

EEOI divides emissions by transport work, which for this vessel and year was 64,376,816 tonne-miles over 33,462 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 4.9% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 10.7% while distance sailed fell 20.1%and CO₂ per nautical mile rose 11.7%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 8,098 t
Methane (CH₄): 0.12 t
Nitrous oxide (N₂O): 0.45 t
