Carbon Capture: Resource considerations and costs for carbon removal
While efforts to reduce GHG emissions should always take priority, meeting climate goals will also require carbon dioxide removal (CDR) — systems that remove carbon directly from the air — likely at the billion-tonne scale by midcentury. The precise amount needed will depend on how fast the world curbs emissions. Carbon removal can take numerous forms, including natural and technological solutions that accelerate current carbon dioxide removal rates. Direct air capture (DAC) is gaining traction as a promising carbon removal approach that will likely be a necessary part of a larger carbo...
