Ship CO2 surcharge

What is a ship CO₂ surcharge?

The ship CO₂ surcharge is imposed by ship operators to compensate for CO₂ emitted during the sea crossing.

How is the ship CO₂ surcharge calculated?

The reference CO₂ price for each month (EEX EUA End of Day Index Price in €/tonne) is taken from the 16th of month N-2 until 15th of the month N-1. It is adjusted with a discount reflecting the use of biofuel (-2% on EU-EU routes and -1% on EU-UK routes) and also for EU phase-in period (-30% in 2025) and for routes to/from the UK (a further -50%). The CO₂ surcharge on individual routes is then calcualted by multiplying the CO₂ reference by a 'trade factor' for each route.
