Air travel produces about 3% of global carbon dioxide emissions, and it is one of the fastest-growing sources of greenhouse gases, according to the International Council on Clean Transportation (ICCT). “The least-emitting flight is one that doesn’t happen at all,” says Nikita Pavlenko , senior fuels researcher for the ICCT. This advice is not practical for people who need to travel long distances or for the airline industry.

Multiple airline companies have announced programs to try to become more sustainable in the coming years. Delta Air Lines recently committed $1 billion to become carbon neutral by 2030. JetBlue pledged to get there by 2040, and United Airlines by 2050 . Many other global airlines around the world have made similar promises. But making air travel more sustainable is not simple.
