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. Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5%
