Emissions and EU ETS
The round voyage burns about 1,012 tonnes of VLSFO, emitting about 3,189 tonnes of CO2. One end of the voyage is in the EU ETS area, so half of the emissions at sea count, plus emissions at the EU berth: about 1,594 tonnes of CO2, or the same number of EU allowances.
From 2026 shipping companies surrender allowances for 100% of in-scope emissions. Who pays is for the charter party to say.
