Carbon capture and storage (CCS) is purported to collect or "capture" carbon dioxide generated by high-emitting activities, and is therefore commonly proposed as a technology to help meet global energy and climate goals. However, CCS does not address the core drivers of the climate crisis or meaningfully reduce greenhouse emissions, and should
