Why the mood has shifted
One year ago analysts worried about modest production levels for sustainable aviation fuel yet 2025 is closing with a wave of encouraging data. Annual output has doubled to roughly one million tonnes and orders for new capacity are accelerating. What changed is a trio of forces: firmer policy signals inventive project finance and unexpected leadership from emerging economies.
Emerging markets seize the initiative
India Argentina and Indonesia are demonstrating that a late start can be an advantage. Their refineries are being certified to run feedstocks such as used cooking oil and agricultural residue from day one avoiding costly retrofits common in older plants. A non obvious insight is that by designing facilities
around locally abundant waste developers lock in both supply security and lower feedstock volatility boosting project bankability.
Mandates create momentum
Europe and the United Kingdom now require two percent SAF blending rising steadily toward 2030. Although airlines voiced cost concerns the rule has already catalysed joint purchase agreements that aggregate demand and smooth price premiums. Similar mechanisms helped solar energy scale a decade ago and may repeat the pattern here.
Financing innovation
Private equity funds are exploring subscription style Energy as a Service contracts that pay producers per litre delivered rather than through traditional offtake guarantees. This approach shifts performance risk to financiers comfortable with infrastructure assets and gives airlines a predictable cost curve. Several pilot deals were quietly signed in 2025 signalling a maturing market.
Collaboration over competition
International organisations are arranging knowledge exchanges where established producers share certification data with newcomers. Early evidence suggests this cuts permitting timelines by up to thirty percent illustrating that transparent collaboration can accelerate global decarbonisation.
Conclusion
Sustainable aviation fuel is moving from promise to practice. With adaptive policy creative finance and south south cooperation the sector looks positioned to outpace earlier forecasts and help aviation chart a credible path to net zero flight.
