Joe Sagues @joesagues.bsky.social · 12/08/2025If the goal of SAF is to mitigate fossil emissions, carbon removal can do the same - potentially with greater scalability and lower cost in the near term. I agree that long-term SAF will be essential, but perhaps carbon removal can serve as a bridge? (2/2) 010
Joe Sagues @joesagues.bsky.social · 12/08/2025The Sustainable Aviation Fuel (SAF) industry is facing headwinds.
