Certainly. The Canadian Hemp Trade Alliance has established a sustainability subcommittee that is doing detailed life-cycle analysis and assessment to provide specific data and evidence in this regard.
The reason that hemp is so attractive in its sequestration potential is because of its nature as a multi-use crop and, in particular, the utilization of fibre in materials, such as building materials and construction materials, and environmental enhancement products, such as environmental remediation mats, non-woven mats, etc. The hemp plant itself does a great job of pulling carbon dioxide out of the atmosphere, but the uses of hemp tie up that carbon that's in the stalk for many years.
I'm not sure if the other two witnesses would care to add to that.
