How will this improve the global average of air quality? If you are removing the CO2 from the air then reintroducing it back into the same environment (assuming it is not repurposed in another sector e.g. jet fuel, commercial containers) wont the net effect be the same?

I understand this will concentrate the pollution significantly and may even reduce it in the short term, but wont the average effects be the same?

By "air quality" I believe he is saying that an extra benefit to being carbon neutral is that their fuel combusts more purely than fuel made from crude oil. This means less SOx, NOx, particulates, etc.

It'll improve net air quality (if it works) because our current methods of producing fuels themselves require other 'carbon negative' energy.
