The UK government has opened a consultation aimed at supporting the sustainable aviation fuel (SAF) sector, with the dual objectives of cutting carbon emissions and fostering economic growth.
At the heart of the proposal is a revenue certainty mechanism (RCM), designed to attract investment in green fuel production while ensuring ticket prices remain stable. Sustainable aviation fuel has the potential to reduce greenhouse gas emissions by up to 70% compared to conventional jet fuel, offering a significant environmental benefit.
The initiative is expected to support up to 15,000 jobs and contribute £5 billion to the UK economy by 2050. The consultation, which runs from 3 March to 31 March 2025, outlines an industry-funded price guarantee to provide financial stability for SAF producers.
This latest move follows the introduction of the SAF Mandate in January 2025, which requires an increasing proportion of aviation fuel to come from sustainable sources. The government has also secured international carbon limits for aircraft, mandating that new aircraft types be 10% more efficient from 2031.
Aviation Minister Mike Kane reaffirmed the government’s commitment to greener air travel, stating: “We are committed to building the technology and fuel supply that will see greener flying become a reality in a way that protects consumers.”
Industry leaders have largely welcomed the initiative. Tim Alderslade, CEO of Airlines UK, backed the mechanism, emphasising the goal of producing SAF “at the cheapest possible price for consumers”. Karen Dee, Chief Executive of AirportsUK, noted that SAF would play a “key role in decarbonising aviation”.
The temporary support scheme aims to stimulate the SAF market, with the government pledging to monitor its impact and manage potential risks through volume and price caps. The initiative is part of a broader strategy to position the UK as a leader in clean energy and sustainable transport.
