As we are all well aware, the aviation industry is undergoing a transformative shift towards sustainability with the emergence of Sustainable Aviation Fuel (SAF) but if you are looking for a high level overview this article on the Medium by Pete Facty, does a nice job of outlining what we will most likely see in the future. 

SAF, derived from renewable sources like biomass and waste oils, significantly reduces greenhouse gas emissions compared to conventional jet fuel. 

Airlines and manufacturers are increasingly adopting SAF to meet environmental goals and combat climate change. Governments worldwide are incentivising its production and use, fostering innovation in the sector. As this eco-friendly alternative gains momentum, it offers hope for a greener future in aviation, aligning with global efforts to reduce the carbon footprint of air travel and mitigate its impact on the environment.
