The Need for Carbon Removal Is Clear

To effectively combat the climate crisis, we’re going to need to remove carbon from the atmosphere. But what’s the best way to do it? Two of the main solutions being considered are direct carbon capture technology and growing trees and each approach has its pros and cons.

Carbon removal is a catch-all term for anything that people do that pulls CO2 out of the air and stores it somewhere else. To meet the world’s climate goals, we would need to do this on a massive scale — anywhere from 440 billion to 1.1 trillion metric tons before the end of the century. That’s more carbon than the U.S. has emitted in its entire history.

So how do we remove all that carbon? There are two carbon removal ideas that have really captured the conversation. One is direct air capture, which involves big factories that suck in tons of CO2 from the atmosphere, chemically concentrate it, and store it deep in the ground. The other idea is to simply plant trees! After all, trees have naturally sequestered carbon for millions of years.
