Sure, that works, and will continue to work. Forests on the other hand help when new, but reach a steady state. However the problem is that at least for the near future burning oil, making plastic, and similar other carbon intensive processes make it near impossible to plant enough trees. Carbon taxes, solar, wind, energy storage, and nuclear offer at least the possibility of offsetting carbon generation.... then plant and sink trees. I do wonder how hard it would be to make a widget that with sunlight could make pure carbon bricks that would be useful as a building material. I think Cory Doctorow described it in one of his sci-fi books. Ideally self replicating of course.
