SAF Output of 2.4 Million Tonnes in 2026 Exposes 2050 Net-Zero Gap

Global sustainable aviation fuel production will reach roughly 2.4 million tonnes in 2026 — just 0.8% of aviation's total fuel consumption, according to IATA. Industry executives meeting at APG World Connect 2026 in Monaco used that figure to question whether aviation's 2050 net-zero goal remains achievable.

The number is not new in kind, only in scale. SAF output climbed from about 1 million tonnes in 2024 to 1.9 million tonnes in 2025. Growth is real. It is also nowhere near enough. IATA estimates the industry needs roughly 500 million tonnes of annual SAF supply by 2050 to stay on its net-zero pathway — more than 200 times the expected 2026 volume.

What does this change for airlines?

The arithmetic leaves carriers with a cost problem, not a choice. SAF still costs substantially more than conventional jet fuel. Airlines already juggle aircraft purchases, operating expenses and environmental compliance, and every tonne of SAF they burn widens that squeeze.

That tension produced the sharpest exchange of the Monaco panel. Asked whether he would rather invest $100 million in a new aircraft or in sustainable fuel, one aviation executive chose the aircraft, arguing that technology offers the better long-term return. Another panelist pushed back hard. Burning SAF still releases carbon dioxide, he conceded, but lifecycle emissions can be substantially lower than those of fossil-derived jet fuel — depending on feedstocks, energy sources and manufacturing processes.

The caveat matters. SAF is not automatically carbon-neutral. Only qualifying production pathways deliver significant lifecycle reductions. Treating every barrel as equivalent overstates the fuel's contribution to net zero.

Where do Europe's carbon revenues go?

The panel then turned on the European Union Emissions Trading System. One participant questioned why more EU ETS revenue is not directed toward SAF production, suggesting stronger financial support for fuel research and manufacturing could attack both the supply shortage and the price premium.

The numbers are large. The European Commission reports the EU ETS generated €38.8 billion in auction revenues in 2024, rising above €43 billion in 2025. Those figures cover the entire trading system, including sectors far beyond aviation — not money collected exclusively from airlines.

EU rules already require member states to spend ETS revenues, or an equivalent financial value, on climate and energy objectives. Current funding supports renewable energy, industrial decarbonization, cleaner transport and technological innovation. The dispute in Monaco was therefore about allocation, not about whether the money serves environmental purposes at all. Executives argued that channeling more of it into SAF production could narrow the price gap with conventional jet fuel and strengthen investment incentives.

Is China winning the SAF race?

Investment pace became the panel's geopolitical fault line. One speaker argued China is moving aggressively to build SAF production capacity while investment elsewhere progresses too slowly, and claimed China accounts for a very large share of global SAF output. That market-share figure has not been independently verified. Current international industry estimates show SAF manufacturing capacity distributed across North America, Europe and Asia-Pacific.

The unverified claim should not distract from the underlying argument. Countries that build production facilities, supply chains and supporting infrastructure now could lock in a competitive advantage as airline demand for lower-carbon fuel grows. For European carriers, access to competitively priced SAF will increasingly shape both regulatory compliance and operating costs.

The Monaco debate also made clear that decarbonization is no longer an airline-only burden. Energy companies, governments, airports and airframe manufacturers all sit inside the problem.

Net zero by 2050 — or 2060?

The panel closed on timing, and the skepticism was specific. One participant noted that large aviation programs routinely suffer delays and need many years to reach commercial service. He backed SAF as a near-term tool but said fuel alone will not solve the industry's long-term emissions problem.

Another executive went further. The next generation of more efficient aircraft technologies, he suggested, may not become widely established across commercial fleets until around 2060 — a decade past the target. Development timelines compound the delay: an aircraft or propulsion system entering service does not instantly displace older jets. Airlines operate aircraft for decades, and fleet replacement is gradual and capital-intensive.

Hydrogen propulsion, advanced airframe designs and more efficient engines could eventually cut aviation's environmental footprint substantially. Their commercial potential still depends on technological progress, infrastructure investment and certification — none of them guaranteed on schedule.

Panelists broadly agreed on one point: stronger cooperation among governments, manufacturers, fuel producers and airlines is essential to accelerate progress. Passengers should expect consequences in ticket prices as carriers absorb the cost of sustainable fuels, environmental regulation and new aircraft investment.

The Monaco session exposed the core problem plainly. Aviation has set an ambitious destination for 2050, but the financial and technological route to it remains undefined. Whether the industry arrives on time may depend less on whether promising technologies exist than on how quickly governments and businesses can turn them into affordable, commercially viable systems at global scale.
