The article only mentions that consuming this particular seaweed eliminates methane. I am missing the production perspective. How much more/less greenhouse gasses are created during production of the seaweed compared to traditional fodder? The net total is what counts.

Well the seaweed itself would take up some CO2 during growth... so you have that bonus too. I'd guess the major costs would come during transport.

Seaweed dries and rehydrates well, and like all vegetables it's mostly water, so if it's grown somewhere where it can be sun-dried then total energy cost for transport could be low.

Also, seaweed is a good source of protein, which for cows tends to come from (imported) soy or corn.
