UK opens F-gas phase-down consultation
5th November 2025
UK: The government’s Department of Environment, Food and Rural Affairs (DEFRA), has opened its consultation portal seeking views on its proposals to amend the F-gas phasedown schedule in Great Britain.
DEFRA proposes changing the HFC phase-down in the F gas regulation by adjusting the existing schedule (which is set out in Annex 5 of the F-gas regulation) from 2027 and adding further steps from 2030 until 2050. It would reduce the HFC quota in England, Scotland and Wales by 46.1 million tonnes of CO2e from 2027-2050.
Those adjustments would mean revising the end target of the phasedown, ie replacing the 79% reduction by 2030 target with a 98.6% reduction by 2048 target.

The consultation will close at 23:59 on 17 December 2025.
Links to the consultation and supporting information are available from the DEFRA website.
