COOL EXPLORER against its type
Built in 2015, it is 1 year newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 102,097 gross tonnage it is smaller than 71% of the other 377 LNG carriers with a recorded tonnage. It is one of 60 LNG carriers here under the Malta flag, 11.2% of the 538 on the register. The same builder is recorded for 563 other vessels here, 82 of them LNG carriers. The returns for 2018–2025 all give Valletta as port of registry.
Its 5,168 t of CO₂ for 2025 is 76% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 525.4 kg CO₂, close to the type median of 533.6 kg. It logged 661 hours at sea against a median of 2,940 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 8 years with reported emissions, the highest was 2022 (31,476 t) and the lowest 2025 (5,168 t). Its efficiency percentile within the type went from 40 in 2018 to 0 in 2019 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2019
Position 1 of 3 qualifying lng carriers by EEOI, at the 0th percentile. The dashed line is the type median, 52.5; this vessel reported 23.6.
EEOI divides emissions by transport work, which for this vessel and year was 2,967,325,765 cubic-metre-miles over 42,836 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 54.3% and CO₂ per nautical mile fell 19.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
