Carbon Dioxide Removal Primer

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.  

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 ...

CDR encompasses myriad techniques and technologies: direct air capture, carbon storage and sequestration in natural basins, bioenergy with carbon capture, reforestation, carbon-friendly soil management practices, ocean enhancement, and many more. Each method has different rates of CO2 uptake, land requirements, energy demands, storage permanence, a... See more
