Scientists at UC Berkeley say they can do the same job with less than half a pound of a fluffy yellow powder.

The powder was designed to trap the greenhouse gas in its microscopic pores, then release it when it’s ready to be squirreled away someplace where it can’t contribute to global warming.

Keeping the concentration of atmospheric carbon dioxide below 450 parts per million is necessary to limit global warming to 2 degrees Celsius .

A version of COF-999 could be ready for direct air capture plants within two years .

Yaghi says it doesn’t require expensive or exotic materials.

Lackner says the entire process will have to become “ 10 times cheaper than it is now” before it can make a real dent in carbon dioxide.
