my feeling would be if it's a "cement" type board with some cellulose fiber then it wouldn't need to be low emitting per se however if it's a mostly cellulose based board with some anhydrite in it then it may need to be low emitting. You can ask mfgr to classify board if it's agricultural based or not.
