Bill Gates now targets airplanes in new war against climate change

Bill Gates states that aviation is one of the hardest sectors to decarbonize due to the engineering challenges of keeping large jets in the air without significant emissions. He notes that sustainable aviation fuels and electric or hybrid aircraft are under development but not yet scalable. Gates also highlights that eliminating some contrails could reduce global warming by up to 2 %, as these cloud formations significantly contribute to climate change.
