Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what estimate they have made of the impact of the Greenhouse Gas Emissions Trading Scheme (Amendment) (Extension to Maritime Activities) Order 2026 on freight and passenger costs on routes between Great Britain and Northern Ireland.

Compliance costs from the UK Emission Trading Scheme fall on ship operators, not passengers, and any fuel or ticket price changes are commercial decisions. Internal analysis, including route specific case studies, indicates final cost impacts on Great Britain–Northern Ireland voyages are minimal for passengers on key ferry routes and well under 1% for freight goods. These findings are consistent with international evidence showing only low single digit ticket price changes, not the larger increases suggested.
