(Bloomberg Businessweek) -- To help battle global warming, companies around the world are expected to spend billions of dollars over the next decade building devices aimed at sucking carbon from the atmosphere. The thing is, Mother Nature already made one. While each acre of most tree species can capture and store 1.1 to 9.5 metric tons of carbon dioxide a year, an acre of empress trees can absorb 103. “The tree has a very Jack and the Beanstalk energy to it,” says Wendy Burton, whose 15-year-old Mesa, Ariz.-based timber company, World Tree, has planted more than 1,000 acres of empress.
Once the trees reach maturity, farmers harvest their wood for use in houses or musical instruments. World Tree investors share in the profits. The trees can regrow easily from the stumps after they've been harvested. Says Cathy Key, the company's chief operating officer: “It's a tree that grows like grass.”
