CONCERTO against its type

Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 22,987 gross tonnage it is smaller than 52% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The returns for 2018–2025 all give SINGAPORE as port of registry.

Its 12,788 t of CO₂ for 2025 is 2.3 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 246.1 kg CO₂, close to the type median of 250.2 kg. It logged 4,459 hours at sea against a median of 2,109 hours for its type that year. 4.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2020 (13,463 t) and the lowest 2024 (4,030 t). Its efficiency percentile within the type went from 14 in 2018 to 31 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 417 of 1,348 qualifying chemical tankers by EEOI, at the 31st percentile. The dashed line is the type median, 14.4; this vessel reported 11.2.

EEOI divides emissions by transport work, which for this vessel and year was 1,140,746,655 tonne-miles over 51,968 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 62.8% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 217.3% while distance sailed rose 234.0%and CO₂ per nautical mile fell 5.0%.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: 12,989 t
Methane (CH₄): 0.20 t
Nitrous oxide (N₂O): 0.74 t
Under EU ETS: 7,740 t, 61% of total

Laden voyages2025

CO₂ on laden voyages: 11,201 t, 88% of total
Fuel, laden: 3,597 t

The rest of the 2025 total was emitted on ballast legs or at berth.
