United Kingdom Expands Emissions Trading Scheme to Ferries and Passenger Vessels
UK ETS to Cover Large Parts of the Maritime Sector from July 2026
The UK government has confirmed the expansion of the UK Emissions Trading Scheme (UK ETS) to the maritime sector. From 1 July 2026, operators of larger ferries, RoPax vessels and passenger ships will be required to monitor their greenhouse gas emissions and surrender emissions allowances under the scheme. The measure is intended to accelerate the decarbonisation of maritime transport and encourage investment in cleaner technologies.
Under the new regulations, vessels of 5,000 gross tonnage (GT) and above will fall within the scope of the UK ETS. The scheme will cover carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) emissions. It applies to voyages between UK ports, domestic cruises departing from and returning to a UK port, as well as emissions generated while vessels are at berth in UK ports.
Additional Costs for Ferry Operators
For ferry companies, inclusion in the emissions trading system represents a new economic challenge. As operators will be required to purchase emissions allowances for their greenhouse gas emissions, operating costs are expected to increase, particularly for vessels relying on conventional fossil fuels.
The new requirements will affect a significant number of RoPax ferries carrying both passengers and vehicles. The additional costs may influence the economic viability of certain routes and are likely to become an increasingly important factor in future investment decisions.
Incentive for Alternative Propulsion Technologies
Many industry observers view the expansion of the UK ETS as an important driver for fleet modernisation. Shipping companies are already investing in battery-electric ferries, hybrid propulsion systems, shore power connections and alternative fuels such as methanol and hydrogen.
By placing a financial value on emissions, the scheme is expected to improve the competitiveness of low-emission technologies. In particular, shorter ferry routes may become increasingly suitable for the deployment of alternative propulsion solutions.
Special Provisions for Northern Ireland and Island Services
To minimise potential impacts on regional connectivity, the UK government has introduced several exemptions and special arrangements. For services operating between Northern Ireland and Great Britain, only 50% of the relevant emissions will initially be subject to the scheme.
In addition, certain essential ferry services connecting remote Scottish islands will remain exempt for the time being. The government has highlighted the importance of these routes for local communities, mobility and the supply of goods and services.
Conclusion
By bringing large ferries and passenger vessels into the UK ETS, the United Kingdom is significantly expanding the scope of its emissions trading system. The new requirements increase pressure on the maritime sector to reduce greenhouse gas emissions and represent another important step towards a more sustainable shipping industry.
