OceanScore said its OceanScore Pool-Price Index (OPX) increased to €225 per tCO₂e in May from €196 in April.
The company said current market behaviour resembles patterns seen at the start of the previous compliance cycle, with a wide range of offers entering the market while overall trading activity remains relatively limited.
According to OceanScore, some quoted prices have reached as high as €300 per tCO₂e, although the majority of offers continue to fall within the €170-€210 range.
The company said the pricing trend reflects an ongoing surplus of compliance balances in the market, with OceanScore data indicating that oversupply conditions are continuing to increase.
The OPX is widely used in the shipping sector as a reference point for FuelEU Maritime pooling costs and commercial planning.
