Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answer of 3 February 2026 to Question 109699, what proportion of the estimated revenue from domestic maritime will result in direct emissions abatement within the maritime sector.

The Government’s Impact Assessment estimates that including domestic maritime in the UK ETS will increase allowance purchase revenue by around £1.9 billion over the 20-year appraisal period, averaging roughly £95 million a year.

Revenue from the UK ETS is not currently hypothecated, but is used to fund the government’s spending priorities, including spending and subsidies supporting the Net Zero transition.

The Government continues to support the maritime sector’s decarbonisation through existing funding, guidance and policies that support the uptake of cleaner technologies.
