The Sustainable Aviation Fuel (SAF) mandates in the USA are set to increase airfares by 20% by 2030, driven by the rising costs of green fuel production and carbon-reduction targets. As the Biden administration accelerates SAF adoption through regulatory frameworks like the Clean Energy Standard, airlines are expected to invest heavily in SAF technology and infrastructure. While SAF will help decarbonize the aviation sector, the additional costs will result in higher airfares for consumers, estimated to rise by $15–$30 per ticket by 2030. However, regulatory incentives will reduce overall expenses for airlines, and fuel production technologies will gradually reduce costs.

The SAF market for US airlines is projected to reach $14.5B by 2030, with a CAGR of 29.6% driven by regulatory mandates and green fuel adoption. The Biden administration’s policies, including the Clean Energy Standard and $2.8B in SAF incentives, will be pivotal in supporting the growth of SAF infrastructure. By 2030, 40% of aviation fuel in the US will be sustainable, helping to decarbonize the aviation sector and meet the net-zero emissions target. However, SAF adoption will lead to a 20% increase in airfares as the cost per flight rises by $15–$30 due to the higher production cost of SAF. Private sector investments in SAF production technologies will reduce costs by 25% by 2030, making green aviation more affordable over time.
The USA is at the forefront of SAF adoption, with airlines like Delta, United, and American Airlines leading the way. The adoption of SAF is driven by regulatory pressures, such as the Biden administration’s clean fuel initiatives, which aim to reduce aviation emissions by 50% by 2030. The supply chain for SAF will see significant investments in production facilities and fuel distribution infrastructure, with over $1.5B in capital expected to flow into the market by 2030. As SAF adoption increases, airlines will pass some of these costs to consumers, causing airfare increases of $15–$30 per ticket. Government policies and subsidies will also help offset the additional costs, while private-sector partnerships will support the expansion of SAF production. By 2030, US airlines will be expected to have fully integrated SAF into their fleet, leading to a 40% reduction in CO₂ emissions across the sector.

The SAF market is segmented into production technologies (50%), government subsidies and incentives (30%), private sector investment (15%), and supply chain infrastructure (5%). Production technologies will account for 50% of the investment, focusing on algae-based SAF, waste-to-fuel, and biochemical conversion methods. Government incentives, including $2.8B in subsidies, will play a critical role in facilitating SAF adoption and reducing the burden on airlines. Private sector investments will focus on scaling SAF production and expanding fuel distribution infrastructure, while supply chain infrastructure investments will ensure that SAF is distributed efficiently across airlines. By 2030, SAF production will make up 40% of the aviation fuel used in US commercial flights.
The USA is leading the SAF market, accounting for 40% of the global share in 2025. Key airline hubs in California, Texas, and Florida will drive the adoption of SAF and sustainable aviation policies. Europe is closely following with 20% of the market, with countries like Germany and France heavily investing in green aviation technologies. The Middle East and Asia-Pacific regions are expected to follow the US lead, focusing on SAF adoption and aviation fuel transition. By 2030, the USA will remain the largest market for SAF globally, contributing to carbon-neutral aviation through the adoption of green fuels and sustainable practices.

Key players in the SAF market include ExxonMobil, Shell, BP, TotalEnergies, and Neste. These companies are leading in SAF production and innovation, particularly with waste-to-fuel technologies and biomass-based SAF. United Airlines, Delta, and American Airlines are major adopters of SAF in their flight fleets, with partnerships to secure long-term SAF supplies. Tesla and SpaceX are also contributing to green fuel development through partnerships with aviation companies. Government incentives and private sector collaboration will play a crucial role in scaling SAF production, reducing costs, and ensuring widespread adoption by US airlines by 2030.
