UK Emissions Trading Scheme: Shipping
The question
To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answer of 10 February 2026 to Question 110103 on the Emissions Trading Scheme, how much revenue does the Government expect to raise per year for the period to 2030 from the extension of the Emissions Trading Scheme to maritime.
Answered by Chris McDonald
The Impact Assessment includes a 20‑year discounted appraisal of the expected effects of extending the UK Emissions Trading Scheme (UK ETS) to domestic maritime.
This assessment projects roughly £1.9 billion in additional revenue to the UK Government over the appraisal period through the purchasing of allowances.
If the analysis is disaggregated to focus on the compliance period from 2026-2030, the estimated increase in revenue is £720 million, reflecting that earlier years account for a proportionally larger share of emissions, and allowance purchases, before the maritime sector begins to decarbonise more substantially.
