Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what assessment they have made of the impact of the Greenhouse Gas Emissions Trading Scheme (Amendment) (Extension to Maritime Activities) Order 2026 on Northern Ireland’s ferry operators.

The Government assessed the implications of extending the UK Emissions Trading Scheme to domestic maritime through a published impact assessment. Analysis does not assess the impact on individual operators, as costs vary widely by fleet, route and commercial arrangements. However, to support policy development, case study analysis of specific routes was carried out, including Great Britain–Northern Ireland ferries. This showed that, even assuming full cost passthrough, the effect on passenger fares was minimal.
