We Need To Take CO2 Out Of The Sky

The key challenges to large-scale removal of carbon dioxide from the air are both technical and sociological. They include: 1) lack of knowledge – about the technologies needed, or how much capital will be necessary to pay for vital infrastructure; 2) fear – of unintended consequences, and that a reimagining of our global energy system will result ...

But to reach net-zero emissions, we need CDR to balance out emissions. Delivering on the idea of net-zero hinges on the development of sustainable CDR technologies and practices. Net-zero, though, is not a resting point; it is imperative to remove all the carbon dioxide we can – and then find new ways to remove more.  

Carbon dioxide removal offers a way to change the math. Extract large amounts of CO2 from the atmosphere and “negative emissions” could, conceivably, balance out the positive variety. It might even be feasible to cross the threshold of catastrophe and then suck enough carbon out of the…
