> The General Sherman removed 1438.892 metric tons of carbon dioxide from the air. Divided by the American yearly CO2 footprint of 16.6 metric tons ,we get 86.7 years of CO2 sequestered in a single tree! Although it took around 2500 years to do so. If your calculations are right, the American should presumably plant 30 of these trees rather than one in order to have a more real-time impact. This is also assuming that each tree planted will follow something like the growth trajectory of the largest tree in the world. I'm also not sure that this calculation is right, for example because using the approximate mass of the tree as the amount of CO₂ fixed by the tree neglects the contribution of the H₂O that was also an ingredient for the tree's cellulose content. (I fully support people planting sequoia trees, though!)
