Maritime transport remains among the largest sources of greenhouse gas emissions. Oil tankers, passenger vessels and huge merchant ships release substantial pollutants into the atmosphere. Yet European institutions have agreed on a robust decarbonisation plan. Between 2025 and 2050, large ships will be required to capture just 20% of their current emissions. The path to cleaner seas is taking shape through standardized fuel rules and tougher efficiency benchmarks that steer the industry toward renewable fuels and lower carbon outputs.
Negotiators from the European Parliament and the Council reached a consensus on a policy framework aimed at cutting polluting emissions from ships operating under EU jurisdiction. The framework sets a timeline that accelerates reductions from a 2% cut starting in 2025 to an 80% reduction by 2050.
The new shipping-fuel standard focuses on practical steps that help the sector shift toward decarbonisation. The emphasis is on renewable energy sources and low-carbon fuels, along with improved energy efficiency across the fleet.
The policy requires gradual greenhouse gas reductions, targeting a 2% decrease over the next two years and a total of 80% by 2050. Interim milestones include a 6% cut by 2030, 14.5% by 2035, 31% by 2040, and 62% by 2045, creating a steady trajectory toward deep decarbonisation.
The measure applies to ships with a gross tonnage exceeding 5,000 tons. These vessels are historically responsible for the largest share of CO2 emissions and account for almost all on-board energy use when they operate within or between European Union ports. In other travel scenarios, around half of the energy consumed on journeys to or from non-EU or outer EU regions falls under a broader scope. The rule reflects an ambition to cover the most energy-intensive operations while encouraging efficiency improvements across the board.
The European Parliament noted during negotiations that Members would decide whether the Commission should review the rules by 2028. Discussions also explored whether the emission reduction requirements should extend to smaller ships or broaden the share of energy sourced from non-EU countries.

The outcome signals a clear direction: ships operating under EU rules will face tighter emissions standards every few years, as technology, fuel choices and operational practices evolve. The approach prioritizes measurable targets, transparent reporting, and ongoing assessment to ensure that the sector can adapt without compromising safety or reliability.
In the end, the air around busy ports could look and feel different. Cleaner exhausts, more efficient propulsion systems, and a growing use of renewable fuels will gradually redefine maritime operations. The plan invites the industry to invest in green technologies, adopt cleaner fuels, and implement energy-saving practices as part of a broader shift toward sustainable maritime transport.
