🔗 Comment “pod” for a link to the episode! The aviation industry has gotten twice as fuel-efficient since 1990, and emissions have still quadrupled. In the latest episode of Second Nature, 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. ‍ #fossilfuels #flying #jetfuel
