2% of current greenhouse gas emissions are creating ammonia for fertilizer from natural gas.

Two potential solutions are a)

Create the ammonia from green hydrogen i.e. made from water with renewavle electricity

b)

Theres a process that turns natural gas (ideally from food waste) into hydrogen plus graphite do the carbon becomes a usable resource ratger than being vented as CO2.




c) use practices that were commonplace before artificial fertilizer was invented; fallowing, manure, compost, etc.

Of course, manure and compost have their own set of CO2 (and methane) emission problems. At least it's carbon neutral I guess.


And get much lower yields as a result
