Key Takeaways:

1. SAF is the most significant lever for achieving aviation’s net-zero goals

Boeing frames SAF within a holistic decarbonization strategy that includes fleet renewal, operational efficiency, renewable energy, advanced technologies, and market-based measures such as CORSIA and carbon removals. Among these tools, SAF represents the largest opportunity for emissions reduction through 2050.

​

2. Scaling SAF is ultimately a finance challenge, not a technology challenge

After years of demonstration flights and technical validation, Boeing is now focused on mobilizing capital and enabling project financing. The priority is convincing investors, banks, and project developers to deploy infrastructure at scale.

​

3. Diverse feedstocks and global partnerships are essential to resilient supply

Boeing remains technology-agnostic, supporting a portfolio of production pathways. Partnerships—from Firefly’s sewage-derived fuel to Norway’s power-to-liquid Norse E-Fuel—enable learning across cost models, business structures, and regional opportunities.

​

4. Book-and-claim systems will play a critical role in bridging supply and demand

With SAF production and demand often misaligned geographically, credible book-and-claim mechanisms can allow emissions benefits to be transferred without physically delivering fuel to every airport. However, regulatory alignment and global confidence-building are still needed.​

​

5. Policy stability and government support will unlock investment and accelerate the tipping point

Boeing collaborates with governments, trade associations, and financing bodies to de-risk supply through long-term certainty, project support structures, and tools such as export credit agencies. Steven emphasized that aviation is currently in the hardest phase—the first 5%—the most difficult segment of any energy transition, but momentum is building.
