Eco Aviation in Trouble: Why Europe’s SAF Plans Are Falling Behind

Here’s the tricky part about going green in aviation: wanting it isn’t enough—you actually have to produce the fuel.

A new warning from Scandinavian Airlines (SAS) puts this into sharp focus. Europe’s push toward sustainable aviation fuel (SAF) is accelerating, especially under the EU’s ReFuelEU Aviation rules, which essentially force airlines to start using cleaner fuels. On paper, it sounds like real progress. In reality, there’s a growing gap between ambition and supply—and it could turn into a full-blown crisis after 2030.

The core issue is simple: demand is being mandated, but production isn’t keeping up.

Take Scandinavia as an example. According to SAS’s analysis, demand for e-SAF in the region could hit 36,000 tons by 2030. Just five years later, that figure may jump to 160,000 tons, and by 2040, exceed 330,000 tons. Those are steep increases by any measure. But here’s the catch—across Europe, there isn’t even a single e-SAF production facility that has reached a final investment decision yet.

To keep up, at least one plant would need to be operational by 2032, and five by 2040. Right now, that looks more like a wish list than a plan.

And when demand outpaces supply, the outcome is predictable: prices rise. Fast. SAS warns that e-SAF could become significantly more expensive than conventional jet fuel, putting serious financial pressure on airlines. That pressure doesn’t just stay on balance sheets—it trickles down to ticket prices, route networks, and ultimately, passengers.

There’s also a bigger competitive angle here. If European airlines are forced to use costly sustainable fuels while others lag behind, they could find themselves at a disadvantage—especially on long-haul routes where margins are already tight.

Perhaps the most ironic risk is this: in trying to reduce dependence on fossil fuels, Europe could end up creating a new kind of dependency. Without strong local production, airlines may be forced to rely on imported sustainable fuels—just under a different label.

So what now?

Europe is facing a choice. It can either slow down its targets and give the industry more time to catch up, or double down—support production with subsidies, incentives, and serious infrastructure investment. SAS makes it clear that the window for action is narrowing.

Because in the end, the transition to greener aviation won’t be decided by targets or policies alone. It will come down to whether the fuel is actually there when planes need it.
