UK Emissions Trading Scheme

Asked by Andrew GriffithConservativeTreasuryTabled Answered 9 February 2026UIN 110485

The question

To ask the Chancellor of the Exchequer, what is the (a) gross and (b) net revenue raised for her Department from the UK Emissions Trading Scheme in the 2024-25 financial year, broken down by auction receipts, administrative costs, and any revenue recycling and hypothecation.

Answered by Dan Tomlinson

Receipts from auctioning of UK Emissions Trading Scheme (ETS) allowances accrue to the exchequer. The Economic and Fiscal Outlook (November 2025) published by the OBR confirms the ETS outturn for 2024-25.

The administrative cost of the UK ETS can be found in the National Audit Office’s report on the UK ETS.

The UK does not hypothecate revenue from the UK ETS, which is subject to a floating carbon price which changes frequently. All receipts from the UK ETS accrue to the consolidated fund, and go to funding government priorities, which includes decarbonisation support for ETS participants.
