That fertilizer accounts for about 2% of global carbon output, but it does seem on track to be replaced with ammonia made from green hydrogen rather than steam reformed from fossil gas.

Probably won't help with runoff issues though, as it'll be chemically identical, just with a lower carbon footprint.
