21 SUNNY against its type
Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 23,273 gross tonnage it is larger than 89% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 51 general cargo ships here under the Singapore flag, 1.7% of the 3,081 on the register. The same builder is recorded for 80 other vessels here, 22 of them general cargo ships. Its MRV returns name it SEA SMILE for 2018–2021 and 21 SUNNY for 2024–2025. The reported port of registry changed: MONROVIA (2018–2021), then Singapore (2024–2025).
Its 3,700 t of CO₂ for 2025 is 31% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 222.4 kg CO₂, 1.8 times the type median of 122.2 kg. It logged 1,419 hours at sea against a median of 3,044 hours for its type that year. 2.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2024 (5,150 t) and the lowest 2021 (1,262 t). Its efficiency percentile within the type was 71 in both 2018 and 2021. Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 65.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 28.1% and CO₂ per nautical mile fell 3.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
