To my understanding, trees are the best carbon sink among plants. Weeds can be extremely important for healthy ecosystems, but are not considered as "carbon sink" per se because they have small roots compared to trees and other plants. (Btw if you have a link to share that talks about weeds as important carbon sinks, I would be very interested to take a look at it. So, please share.)
This technique utilizes invasive weeds to make pellets, instead of cutting trees.
I think it really depends. Trees actually aren't as good at storing carbon as bog plants are. Peat just keeps stacking up indefinitely, while trees only hold what carbon they can hold while alive, unless something unusual happens (e.g., sinking in a swamp, buried by humans, etc)
This was actually a problem in Scotland where there were misguided attempts at planting trees into peatlands for ecological benefit, but they actually did more harm.
With herbacious, or shrubby plants, it's going to really depend. Some perennial plants are able to build up a pretty decent root mass in the soil that keeps the carbon locked up in the soil for a long time. It may not be as good as trees, but there are plenty of places that just can't support the biomass of trees (deserts, prairies, savannahs, etc.), and non-tree plants are the best you can do there.
This is all also modified by the fact that a lot of times, invasive plant removal is desirable anyway, so you might as well utilize the waste.
