F gas Regulation in Great Britain – Consultation on reform of the HFC phasedown
The Department for Environment, Food & Rural Affairs (Defra) has launched a consultation on a proposal to reform the phasedown of hydrofluorocarbons (HFCs) contained in the Regulation on Fluorinated Greenhouse Gases (the F gas Regulation).
The proposal is to change the HFC phasedown in the F gas Regulation by adjusting the existing schedule from 2027 and adding further steps from 2030 until 2050. Those adjustments would mean revising the end target of the phasedown – i.e. replacing the 79% reduction by 2030 target with a 98.6% reduction by 2048 target.
Details of the reform proposal can be found here.
