At Climate Week NYC, Alaska Air Group sustainability director Ryan Spies outlined the airline's approach to cutting emissions, which relies on sustainable aviation fuel (SAF) and investments in fuel-efficient aircraft. SAF currently supplies less than 1% of global aviation fuel, so Alaska Air co-founded a $150 million fund with Breakthrough Energy Ventures to back SAF innovators. Spies noted that recent oil price volatility has made SAF more cost-competitive with conventional jet fuel, shifting the economic case. The airline also backs JetZero, a blended-wing body aircraft developer claiming 50% fuel reduction, and Ampaire, a hybrid-electric startup for smaller planes. Spies emphasized that aviation is one of the hardest sectors to decarbonize due to physics and thin profit margins, making strategic bets necessary. The article also mentions the Cascadia Sustainable Aviation Accelerator, a regional effort to build a SAF hub in the Pacific Northwest.

Alaska Air's Ryan Spies explains why aviation decarbonization is slow. SAF supply under 1% of fuel, they're betting on a $150M fund with Breakthrough and next-gen planes like JetZero. Worth reading for the economics and the physics constraint.

The interesting bit is that Iran war oil prices make SAF competitive now. That flips the cost argument, but production still lags. If they can scale feedstocks, maybe this actually moves.

JetZero says 50% fuel cut with blended wing. Prototype next year, passengers 2030. That timeline seems optimistic. Ampaire's hybrid for small planes is more near term, but Hawaii market? Curious about certification path.

The Cascadia accelerator is good for regional supply. But without a carbon price on jet fuel, SAF adoption will stay driven by voluntary corporate demand. That limits scale. Check how the fund picks winners.

They mention SAF from captured carbon and waste. But the energy input matters. If it takes too much renewable electricity, it might be better used elsewhere. Aviation is hard, but let's see the life cycle numbers.
