Just half a pound of the stuff may remove as much carbon dioxide as a tree can, according to early tests. Once the carbon is absorbed by the powder, it can be released into safe storage or be used in industrial processes, like carbonizing drinks.

“This really addresses a major problem in the tech field, and it gives an opportunity now for us to scale it up and start using it,” says Omar Yaghi, a chemist at the University of California, Berkeley. It’s not the first material to absorb carbon, but “it’s a quantum leap ahead [of other compounds] in terms of the durability of the material”.
