Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether his Department has made an estimate of the compliance cost to the maritime sector of expanding the UK Emissions Trading Scheme to international maritime voyages in each of the subsequent ten years from 2028.

We published a consultation in late November seeking views on a number of proposals to expand the UK ETS to the international maritime voyages.

When we responded to the consultation on expansion to domestic maritime emissions, we also published a full impact assessment. This includes detail on the compliance costs for the expansion to domestic voyages.

We will publish a full impact assessment on the expansion to international voyages alongside the Authority Response to the consultation.
