The Baobab tree, as a soft deciduous tree, sequesters more carbon than most trees, meaning it absorbs more carbon from the air than it releases.

Also, "A sweeping study of forests around the world finds that the older the tree, the greater its potential to store carbon and slow climate change. The 38 researchers from 15 countries found that 97 percent of trees from more than 400 species studied grew more quickly as they aged, thus absorbing more carbon." (Pacific Forest Trust)
