Sustainable aviation fuel is drawing renewed interest as mandates begin to create real demand and geopolitical disruption puts fuel security back on the agenda. Recent industry discussion at the Global Aerospace Summit in St. Louis highlighted how European SAF rules and tensions affecting oil transit routes are pushing airlines, fuel suppliers and policymakers to treat SAF as both a decarbonisation measure and a resilience strategy.
The debate centres on whether policy alone can scale the market quickly enough. Existing mandates are helping build demand, but they are also exposing gaps in supply, financing and market design. Projected 2030 demand is increasingly tied to a mix of binding rules, expected future mandates, targets, incentives and voluntary purchases, with a substantial share still dependent on additional policy support.
Industry observers have also pointed to a broader shift in the conversation. SAF is no longer framed only through climate goals; it is now being linked to energy security as conflict and high oil prices increase attention on fuel supply risk. That dynamic is particularly relevant in Europe, where binding SAF requirements are already in force and where policymakers are weighing how to encourage production without relying on pilot-scale demand alone.
