We know trees and plants can remove CO2 from the atmosphere. Why can't we?

Startups have figured out how to remove carbon from the air. Will anyone pay them to do it?

Three startups, Carbon Engineering, Global Thermostat and Climeworks, are making strides with technology that can directly remove carbon dioxide from the air. What they need now is a viable business model

The Calgary-based company is one of a crop of startups placing bold bets on technology designed to directly capture CO2 from the air.

All three companies talk about a hypothetical future in which CO2 will be harvested from the sky and transformed, using renewable energy, into low-carbon fuels

If direct air capture of CO2 is to emerge as a meaningful climate solution, it would have to be built out at a global, industrial scale, costing billions of dollars.

Still, while direct air capture won’t be ready for deployment any time soon, climate experts say negative emissions technologies merit more attention. In a detailed review of climate intervention technologies published in February, The National Academies of Sciences described direct air capture as “an immature technology” and called on the government to invest in research “to improve methods of carbon dioxide removal and disposal at scales that would have a significant global climate impact”.
