The FuelEU Maritime Regulation was introduced as part of the EU's efforts to support decarbonisation. FuelEU Maritime sets maximum limits for the yearly average greenhouse gas (GHG) intensity of the energy used by ships above 5,000 gross tonnage trading in the EU. HFO, LFO, MDO and MGO will be fined from 2025 onwards. LNG will also be fined from 2030 onwards depending on the fuel type.
