NOx consists of the following three gasses: NO, N2O, and NO2
Which one is also a greenhouse gas?
N2O is also known as laughing gas (used at the dentist during tooth pulling). But due to the very long lifetime in the atmosphere, where it is a greenhouse gas, we should limit how much we let into the atmosphere. Thus all the solutions to NOx removal (acid deposition), or mitigation, or prevention, are applicable to N2O reductions.
