In this episode, we reckon with the guilt of flying, tracing it from economy class all the way up to private jets, where a handful of ultra-wealthy passengers emit up to 500 times more carbon than the average person annually. Plus, we dig into sustainable aviation fuel with Alyssa Norris from Aether Fuels and what it would actually take to make flying something we don't have to feel guilty about. Episode rundown: (00:35) - Should we feel guilty about flying? (03:12) - Our flying footprint (05:17) - Reckoning with guilty consciences (09:52) - What is SAF and why aren’t all planes using it? (27:19) - Following the money from private jets to economy (37:08) - Individual actions for systemic change 📱 Want to make your money count?
