Calcium-looping direct air carbon capture and storage (DACCS) is a mature technology positioned for gigatonne-scale carbon dioxide removal (CDR). However, a holistic assessment of its system-wide environmental performance and large-scale implications remains critically absent. Here, the authors present a prospective life cycle assessment (LCA) of megatonne-scale calcium-looping DACCS systems under projected 2050 energy scenarios, evaluating CO₂ removal alongside 18 other environmental impact categories.
