At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. If you want to get to a net-zero aviation sector, this is a potential way of solving the air pollution part of it, which is significant, and in a way that’s technologically quite viable.
