This podcast episode emphasizes the challenges of decarbonizing the aviation industry, especially the urgent need to decrease CO2 emissions. The industry's goal is to reduce its absolute footprint by 13% by 2030 and 80% by 2050. Three solutions are presented: changing the fleet mix, exploring alternative propulsion technologies, and transitioning to sustainable aviation fuel (SAF). SAF is seen as the most realistic pathway to achieve 2030 goals. Currently, SAF comprises less than 1% of aviation fuel, facing constraints such as cost, availability, environmental impact, and infrastructure. However, there is growing support for SAF, including government incentives and airline commitments. The podcast promises continued updates on the aviation industry's decarbonization journey.
