Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, with reference to his Department's document entitled Maritime Decarbonisation Strategy, published on 25 March 2025, when he will announce the outcome of the consultation on the application of the UK Emissions Trading Scheme to shipping operating in UK waters.

A second, technical consultation on the expansion of the UK Emissions Trading Scheme to include the maritime sector closed in January 2025. The UK ETS Authority is currently analysing responses and finalising policy design for implementation. The consultation outlined that the scheme would apply to domestic voyages between UK ports, including voyages that begin and end in the same UK port. The Authority also proposed to include emissions at berth in UK ports (irrespective of whether a ship is undertaking a domestic or international voyage). We will publish the Authority Response to this consultation in due course.
