The government will by 26 April confirm how it will compel airlines to use SAF in increasing amounts and instruct fuel suppliers on their obligations.
The announcement may also feature a price stability mechanism to help airlines manage the additional cost of SAF and to boost production.
Campaign groups are highlighting what they claim are pitfalls in the transition towards SAF, particularly SAF produced from waste products.
Speaking on Thursday (11 April) during a briefing hosted by a group of environmental NGOs, Cait Hewitt, Aviation Environment Federation policy director, said SAF should instead be referred to as “Alternative Jet Fuels".
