  • Extending the UK Emissions Trading Scheme cap beyond 2030

    Date published: 8 December 2025

    The UK Emissions Trading Scheme (ETS) Authority has published a Response following a period of public consultation seeking input on proposals for extending the UK ETS beyond the end of Phase I at midnight on 31 December 2030.

    The UK ETS Authority has analysed stakeholder views and feedback on the consultation to extend the UK Emissions Trading Scheme beyond 2030, including the advice of the Climate Change Committee, and has made the following decisions:

    • the UK ETS will be extended into a Phase II from 2031
    • this phase will run for 10 years from 1 January 2031 to 31 December 2040
    • banking of allowances will be permitted between Phase I and Phase II of the Scheme

    Next steps

    We will seek to consult again on a specific trajectory for the Phase II cap in due course, including the analytical basis for the range of trajectories we are considering, and the emerging impacts of those trajectories.​

    The entire second-stage consultation process, including an Authority response, will occur sufficiently ahead of the beginning of Phase II on 1 January 2031 to provide the required certainty for participants.
