Corporate demand for sustainable aviation fuel could grow as much as sixfold by 2030, according to IATA, a projection that lands as airlines scramble for every drop of SAF they can contract.

The figure comes from the International Air Transport Association, the trade body representing the world's carriers, and it points at a specific slice of the SAF market: fuel bought by corporations rather than airlines themselves. Companies with heavy business-travel footprints — banks, consultancies, technology firms — have emerged as willing buyers, using SAF purchases to cut the emissions attributed to their own flying.

Why does the corporate slice matter?

Airlines face a supply problem before they face a demand problem. SAF output remains a fraction of global jet fuel consumption, and most of what exists gets snapped up through bilateral agreements, government mandates and book-and-claim schemes. Corporate buyers bring fresh money to the table.

If IATA's upper-bound projection holds, company-funded demand in 2030 would sit six times above today's level. That scale of growth would matter for three reasons:

• It would pull new capital into SAF production capacity, which remains the binding constraint on decarbonising aviation.
• It would give airlines a way to fund premium-priced fuel without bearing the full cost difference on their own margins.
• It would pressure book-and-claim accounting frameworks to scale up and win corporate trust in the certificates being sold.

What stands between the projection and the fuel?

A sixfold increase in demand does not guarantee a sixfold increase in supply. Production capacity, feedstock availability and refinery economics all constrain how much SAF actually reaches airports by 2030. Corporate buyers can sign contracts; whether those contracts convert into delivered barrels depends on plants getting built.

That distinction — contracted demand versus physical supply — is where IATA's number should be read carefully. It describes what corporations are prepared to buy, not what producers are guaranteed to deliver.

What comes next?

The projection gives airlines, fuel suppliers and corporate travel buyers a shared benchmark for negotiations through the decade, and the gap between sixfold demand and today's constrained supply now defines the commercial race in aviation fuel.
