Sustainable aviation fuels (SAF) are clear fuels, created from sources similar to used cooking oil, agricultural residues and different waste, that can be utilized to energy plane rather than or alongside standard jet gas. Governments worldwide have been investing closely in analysis and improvement into SAF in a bid to decarbonize one of many hardest-to-abate industries – aviation. Nonetheless, current strikes by the Trump administration threaten to stall progress on U.S. innovation and the manufacturing of SAF.
Why We Want SAF and How you can Speed up Deployment
Air site visitors is anticipated to double by 2042, from round 12 billion passengers a 12 months at current. Aviation contributed 2.5% of worldwide energy-related CO2 emissions in 2023, having grown quicker between 2000 and 2019 than rail, street, or transport, in line with the Worldwide Power Company (IEA).
There’s a vary of SAFs at present getting used or trialed in numerous plane. SAF can cut back carbon emissions by as much as 80% on a lifecycle foundation. Whereas different different inexperienced aviation options are being developed, similar to batteries and hydrogen gas cells, SAF seems to be probably the most viable within the mid-term, with a number of airways already mixing SAF with standard jet gas to scale back emissions.
The worldwide SAF market was valued at $2.06 billion in 2025 and is anticipated to develop at a compound annual progress charge of 65.5% over the subsequent 5 years to attain $25.62 billion by 2030. Manufacturing is forecast to extend from 0.30 billion gallons in 2025 to three.68 billion gallons in 2030.
Nonetheless, many corporations are deterred from utilizing SAF, as an alternative of jet gas, as a result of excessive price ticket, which is anticipated to stay between two and thrice extra pricey by way of 2030. Scaling up manufacturing would doubtless drive down value, however demand stays tepid at current as a result of value.
The CEO of Dubai Airports, Paul Griffiths, stated, “The worldwide jet gas market is value round $254 billion per 12 months, with SAF representing simply 0.7% of whole gas manufacturing.” In the meantime, if SAF manufacturing doubles each two years, it might take over seven and a half years for 10% of whole jet gas to return from sustainable sources, in line with Griffiths. He believes, “Trade and governments have started working collectively to create a degree taking part in area of funding that doesn’t incentivize poor conduct.” Griffiths recommends introducing a levy on aviation gas or ticket costs to put money into SAF innovation and manufacturing.
Progress earlier than Funds Cuts
In america, funding into SAF analysis and improvement has elevated lately because of favorable local weather insurance policies and monetary incentives launched underneath the Biden Administration’s 2022 Inflation Discount Act (IRA).
Below Biden, the U.S. aimed to be producing 3 billion gallons of SAF a 12 months by 2030, with the intention of scaling up output to produce all business flights by 2050. Nonetheless, the current rollback of a variety of local weather and energy-related incentives underneath the Trump administration is making attaining this goal appear more and more unlikely.
In June, the U.S. Senate tax-writing committee proposed reducing the 45Z tax credit score’s extra subsidy for SAFs. Political strikes similar to these have created larger uncertainty throughout the choice gas trade and will deter buyers from funding initiatives.
A number of U.S. startups specializing in SAF have reported undertaking delays in current months, in addition to a lack of curiosity from buyers. If the sector can not maintain political backing, creating the SAF wanted to help aviation decarbonization goals will probably be an uphill battle. As well as, larger deregulation underneath the Trump administration could make aviation corporations much less desirous to put money into emissions discount efforts.
Whereas home SAF operations could falter, the trade is anticipated to proceed rising on a worldwide scale, as governments and airways attempt to decarbonize. SAF manufacturing in Europe and Asia will develop considerably within the coming many years, in nations similar to France, the Netherlands, and Japan, supported by favorable authorities insurance policies.
Trade Failings
It isn’t simply U.S. coverage that’s limiting SAF progress, as a number of trade failings have been seen lately, which undermine lots of the world SAF targets for the approaching many years.
A number of airways have been accused of greenwashing by overstating their mid-term SAF targets with out the manufacturing pipeline to again it up. The Worldwide Air Transport Affiliation (IATA) expects SAF will contribute simply 0.7% of whole jet gas this 12 months, up from 0.3% in 2024. The IATA set the purpose of web zero emissions by 2050, which might require airways to extend SAF to 118 billion gallons a 12 months, at greater than 300 occasions the present manufacturing charge.
Whereas airways have introduced 165 SAF initiatives over the previous 12 years, solely 36 have come to fruition, in line with a report by Reuters. If all of the pending initiatives introduced by airways reached their most potential, it might solely add 12 billion gallons of SAF manufacturing, the Reuters evaluation discovered, which is round 10% of what’s wanted to attain the web zero goal. This means that larger collaborative efforts must be made by political actors, gas corporations and the aviation sector, on a global degree, to reinforce SAF manufacturing and higher regulate the sector to encourage uptake.
