Can Sustainable Aviation Fuels Enable Guilt-Free Flying?

Video Description

Remember the time-traveling DeLorean from the 1985 film series Back to the Future? And how Doc, the disheveled inventor-scientist with Einsteinian hair, powered his time-traveling DeLorean with banana peels and pizza? While time travel and flying cars remain a figment of human imagination, waste-fueled flights are on aviation’s not-too-distant horizon. Fasten your seatbelts because in this video, we’re flying high into blue skies to see how the aviation industry is changing its energy itinerary by going green with new, waste-based fuels called Sustainable Aviation Fuels, or SAF, that can directly substitute for existing jet fuel, without the CO2 emissions. We’ll look at the state of emissions from the aviation industry today and why it’s so challenging to eliminate its climate impacts. We’ll also learn about SAF, what it is and how it’s made. And, we’ll dig into some SAF data to unearth adoption trends and to see what it will take to scale SAF towards net zero aviation, and I will share what happened when I purchased SAF for my own upcoming flight, I got the hugest shock and I think you will too when you see what happened!
