Aviation’s climate ambitions are hitting a political wall. Bill Gates and IATA warn that without global coordination, even the best technologies won’t deliver on decarbonization goals.
Bill Gates said that aviation is one of the hardest sectors to decarbonize, warning that it will require urgent innovation and stronger government policies to drive down emissions.
“The world has made meaningful progress in the last decade, cutting projected emissions by more than 40%,” Gates wrote in his annual note for 2026. “But we still have a lot of innovation and scaling up to do in tough areas like industrial emissions and aviation.”
Aviation is especially hard to decarbonize due to long aircraft lifespans and the high cost of sustainable aviation fuel, which is three to five times that of jet fuel. And SAF still makes up just 0.7% of global supply.
Gates warned that unchecked climate change will cause suffering on par with
