Global production of Sustainable Aviation Fuel (SAF) is set to reach just 2.4 million tonnes in 2026, covering a mere 0.8% of total aviation fuel consumption worldwide, according to estimates released by the International Air Transport Association (IATA). The figures underscore the widening gap between the airline industry's net-zero ambitions and the pace of clean fuel adoption.

Scale of the Shortfall

Airlines are projected to spend approximately $4.3 billion on SAF this year — a significant outlay that nonetheless buys a negligible share of their total fuel needs. The aviation sector has committed to achieving net-zero carbon emissions by 2050, a target that analysts say requires SAF to meet roughly 65% of future fuel demand. At current trajectories, that goal looks increasingly out of reach.

What IATA's Leadership Said

Willie Walsh, IATA's Senior Vice President Sustainability and Chief Economist, described the pace of SAF development as 'disappointing' — five years after the industry formalised its net-zero commitment. Walsh pointed to two primary obstacles: ineffective government policies and what he characterised as a lack of interest from oil companies in scaling up production capacity.

He further noted that recent disruptions in global energy markets, which might have been expected to accelerate investment in renewable fuels, have not translated into the financial incentives necessary to build a commercially viable SAF market.

What Needs to Change

IATA has called for coordinated action across governments and industry stakeholders. The association's recommendations include expanding renewable energy supplies, ensuring open access to fuel infrastructure, strengthening production incentives and investment frameworks, and fostering a global SAF market with sufficient volumes and commercially viable pricing.

Notably, IATA also stressed the need for a global 'book-and-claim' system — a mechanism that would allow airlines and fuel producers to participate in the SAF market irrespective of their geographic location, while supporting harmonised standards and fair competition across borders.

Why This Matters for Aviation's Climate Future

Aviation accounts for roughly 2-3% of global CO₂ emissions, and unlike road transport, it has limited electrification pathways at scale in the near term, making SAF the industry's primary decarbonisation lever. The fact that SAF remains below 1% of fuel use in 2026 — more than a decade into serious industry-level climate commitments — signals a structural policy and investment failure, not merely a technological one. This comes amid growing regulatory pressure from the European Union and other jurisdictions mandating SAF blending requirements, which could further strain supply chains already running far short of demand.

Whether governments and energy majors respond with the urgency IATA is demanding will likely determine how credible the aviation industry's 2050 net-zero pledge remains in the years ahead.
