A startup using minerals to draw down CO2 has scored funding—and its first buyer

Removing the greenhouse gas from the air will likely be necessary, along with radical emissions cuts, to keep temperatures from rising 2˚C.
What it will take to achieve affordable carbon removal
Another big direct-air-capture plant is moving ahead, but a new study finds we may need to build many more before the economics start to make sense.
