I recently read a couple of articles about Nitrous Oxide, which explained the following...

It is the most overlooked greenhouse gas, which is especially worrying because in terms of its heat trapping ability, it is 300 times worse than CO2.

I also learned that Nitrous Oxide is principally produced by modern agriculture, because artificial fertilizers are used, and once they are mixed into the soil, microbes begin a chemical chain reaction whose end product is Nitrous Oxide.

So I've been thinking about ways to curb the production of this gas which, given the scale of agriculture in this world, must produced in vast quantities every day.

The first and most obvious thought is to invent and use different artificial fertilizers that don't end up precipitating the production of nos. But someone here on Reddit suggested designing car engines that burned Nitrous Oxide as fuel. If this is possible, though, what would the exhaust from such a vehicle or factory machine consist of? Wouldn't we just be trading six of one for half a dozen of the other, in terms of greenhouse gases?
