Not necessarily about the national inventory report, but I will provide an observation. During the period when the plant is capturing the carbon for the production of seed and grain, as soon as the grain is used for feed, food, etc., that carbon is released. It's not something that is actually stored.
It's not like a tree that is cut and burned or used, and the carbon stays there. That carbon gets recycled as soon as we actually use it. It's released again into the atmosphere when we use it for food.
