Paulownia or Empress/Princess trees are one of the other top contenders from a growth/carbon sequestration standpoint[0]. They're one of the only trees that use C4 photosynthesis (more commonly employed by grasses like bamboo) than the C3 process most trees use. This lets them grow up to 20ft/6m per year, and they're able to be harvested commercially within five years. They're also good from a woodworking perspective: traditionally, parents of daughters in southern Japan would plant a kiri tree on the birth of a daughter and then cut it down to make chests, drawers, and boxes for their daughter's marriage ceremony. I has a higher strength:weight ratio than balsa wood, and is pest and rot resistant. Other fun fact: they resprout from the stump after cutting, similar to coast redwoods.
